Answer:

35

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 7 on the left side and the dividend 249 on the right side like this:

   7 ⟌ 2 4 9

Step 2:

The divisor (7) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

       0    

   7 ⟌ 2 4 9

Step 3:

Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.

       0    

   7 ⟌ 2 4 9

      0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

       0    

   7 ⟌ 2 4 9

     - 0    

       2    

Step 5:

Move down the 2nd digit of the dividend (4) like this:

       0    

   7 ⟌ 2 4 9

     - 0    

       2 4  

Step 6:

The divisor (7) goes into the bottom number (24), 3 time(s). Therefore, put 3 on top:

       0 3  

   7 ⟌ 2 4 9

     - 0    

       2 4  

Step 7:

Multiply the divisor by the result in the previous step (7 x 3 = 21) and write that answer at the bottom:

       0 3  

   7 ⟌ 2 4 9

     - 0    

       2 4  

       2 1  

Step 8:

Subtract the result in the previous step from the number written above it. (24 - 21 = 3) and write the answer at the bottom.

       0 3  

   7 ⟌ 2 4 9

     - 0    

       2 4  

     - 2 1  

         3  

Step 9:

Move down the last digit of the dividend (9) like this:

       0 3  

   7 ⟌ 2 4 9

     - 0    

       2 4  

     - 2 1  

         3 9

Step 10:

The divisor (7) goes into the bottom number (39), 5 time(s). Therefore put 5 on top:

       0 3 5

   7 ⟌ 2 4 9

     - 0    

       2 4  

     - 2 1  

         3 9

Step 11:

Multiply the divisor by the result in the previous step (7 x 5 = 35) and write the answer at the bottom:

       0 3 5

   7 ⟌ 2 4 9

     - 0    

       2 4  

     - 2 1  

         3 9

         3 5

Step 12:

Subtract the result in the previous step from the number written above it. (39 - 35 = 4) and write the answer at the bottom.

       0 3 5

   7 ⟌ 2 4 9

     - 0    

       2 4  

     - 2 1  

         3 9

     -   3 5

           4

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 249 divided by 7 calculated using Long Division is:

(a) the equation of the least squares line is y = (3/5)x - 1/5. b) Hence, the least-squares error for the given data points is 26/5.

To find the slope, we use the formula:

m = (nΣxy - ΣxΣy) / (nΣx^2 - (Σx)^2)

Using the given data points:

Σx = -1 + 2 + 1 = 2

Σy = -1 + 2 + 0 = 1

Σxy = (-1)(-1) + (2)(2) + (1)(0) = 5

Σx^2 = (-1)^2 + 2^2 + 1^2 = 6

n = 3

Substituting these values into the formula, we get:

m = (3(5) - (2)(1)) / (3(6) - (2)^2) = 3/5

To find the y-intercept, we use the formula:

b = (Σy - mΣx) / n

Substituting the values, we get:

b = (1 - (3/5)(2)) / 3 = -1/5

Therefore, the equation of the least squares line is y = (3/5)x - 1/5.

(b) To compute the least-squares error, we need to calculate the sum of the squared differences between the observed y-values and the predicted y-values using the least squares line.

Using the given data points and the equation of the least squares line, we calculate the squared differences and sum them up:

(-1 - (-1/5))^2 + (2 - (6/5))^2 + (0 - (2/5))^2 = 26/5

Hence, the least-squares error for the given data points is 26/5.

Answer:

b. To find the probability a customer who ordered pancakes came to thediner late, we need to look at the intersection of the "pancakes" row and the "late" column. This gives us a probability of 0.1, or 10%

c. To determine whether breakfast choice and meal time are independent, we need to see if the probability of one event changes based on the occurrence of the other event. In this case, it seems that breakfast choice and meal time are not independent, as the probability of being late seems to differ based on what breakfast item the customer chose. For example, the probability of being late is higher for customers who ordered pancakes compared to those who ordered cereal. Therefore, the choice of breakfast item appears to be related to the probability of being late, and so breakfast choice and meal time are not independent.

Answer:

The cost of  0.76 pounds of onion is  \(x = \$ 0.988  \)

The  cost of  1.5 pounds  of  peppers is \( y = \$ 1.455\)

The  total cost is \(z =  \$ 2.443  \)

Step-by-step explanation:

From the question we are told that

  The  cost of one pound of pepper is  C = $0.97

   The cost of one pound of onion is  \(C_o = \$ 1.30\)

   Generally the cost of 0.76 pound of  onion is mathematically represented as

      \(x =  \frac{0.76 * 1.30}{1}\)

=>      \(x = \$ 0.988  \)

   Generally the cost of 1.5pound of  peppers  is mathematically represented as

            \( y  =  \frac{1.5 * 0.97}{1}\)

=>          \( y = \$ 1.455\)

The total cost of 0.76 pounds of onions and 1.5 pounds of peppers is

      \(z =  x+ y\)

=>    \(z =  0.988 + 1.455 \)

=>    \(z =  \$ 2.443  \)

Based on the data collected from the random sample, it can be expected that approximately 35 seventh graders would attend after-school programs out of a total of 200 seventh graders attending Lucy's school.

To determine the expected number of seventh graders who would attend after-school programs, we can set up a proportion based on the data collected from the random sample.

The proportion can be calculated as follows:

(Number of seventh graders attending after-school programs) / (Total number of seventh graders) = (Number of respondents attending after-school programs) / (Total number of respondents)

Let's denote the expected number of seventh graders attending after-school programs as x. We can set up the proportion as:

x / 200 = 7 / 40

To solve for x, we can cross-multiply and then divide:

40x = 7 * 200

40x = 1400

x = 1400 / 40

x = 35

Therefore, based on the data collected from the random sample, it can be expected that approximately 35 seventh graders would attend after-school programs out of a total of 200 seventh graders attending Lucy's school.

The true statement is "Every seventh-grade class has 12 more students than a kindergarten class." (option d).

For the seventh-grade class, the mean is 32, which is larger than the mean for the kindergarten class. This means that, on average, seventh-grade classes have more students than kindergarten classes. The MAD for the seventh-grade class is 2, which is larger than the MAD for the kindergarten class.

This suggests that the deviation from the mean for each data point in the seventh-grade class is larger, on average 2 students, than for the kindergarten class. This means that the size of seventh-grade classes is more variable than kindergarten classes.

Option D is correct because while the difference between the means of the two classes is 12, this does not mean that every seventh-grade class has 12 more students than every kindergarten class.

Hence the c correct choice is option (d).

We can use the double number line to find the cost of buying a different number of bags of rice or the number of bags of rice we can buy for a given amount of money.

The given double number line shows that it costs $3 to buy 2 bags of rice. This means that the cost of 1 bag of rice is $1.50.

To find the cost of buying a different number of bags of rice, we can use the double number line.

Suppose we want to know the cost of buying 5 bags of rice. We can do this by starting at the number 2 on the top line and following the diagonal line down to the bottom line.

Then, we can read off the number on the bottom line that corresponds to 5 on the top line.

This gives us a cost of $7.50 for 5 bags of rice.

We can also use the double number line to find the number of bags of rice that we can buy for a given amount of money.

For example, if we have $6, we can find the number of bags of rice we can buy by starting at the number $3 on the bottom line and following the diagonal line up to the top line. Then, we can read off the number on the top line that corresponds to $6 on the bottom line.

This gives us a value of 4 for the number of bags of rice.

Therefore, we can use the double number line to find the cost of buying a different number of bags of rice or the number of bags of rice we can buy for a given amount of money.

Diversified Citrus Industries will sell Zap to wholesalers at a price of $0.035 per 8-ounce can. The contribution per unit for Zap is -$0.205, indicating potential profitability issues.

a. To determine the price at which Diversified Citrus Industries will be selling its product to wholesalers, we need to consider the suggested retail price, the unit variable costs, and the desired margins for retailers and wholesalers. The suggested retail price to the consumer for the 8-ounce can is $0.05. The unit variable costs for the product are $0.18 for materials and $0.06 for labor. The company intends to give retailers a margin of 20% off the suggested retail price and wholesalers a margin of 10% of the retailer's cost.

Price to Wholesalers = Suggested Retail Price - Retailer's Margin - Wholesaler's Margin

Price to Wholesalers = $0.05 - ($0.05 * 20%) - ($0.05 * 10%)

Price to Wholesalers = $0.05 - $0.01 - $0.005

Price to Wholesalers = $0.035

Therefore, Diversified Citrus Industries will be selling its product to wholesalers at a price of $0.035 per 8-ounce can.

The contribution per unit for Zap can be calculated by subtracting the unit variable costs from the selling price to wholesalers:

Contribution per Unit = Price to Wholesalers - Unit Variable Costs

Contribution per Unit = $0.035 - ($0.18 + $0.06)

Contribution per Unit = $0.035 - $0.24

Contribution per Unit = -$0.205

Since the contribution per unit is negative, it means that the variable costs exceed the price to wholesalers. This suggests that the product may not be profitable in its current pricing and cost structure.

The break-even unit volume in the first year can be calculated by dividing the fixed overhead costs by the contribution per unit:

Break-even Unit Volume = Fixed Overhead Costs / Contribution per Unit

Break-even Unit Volume = $90,000 / (-$0.205)

However, since the contribution per unit is negative, the break-even unit volume cannot be determined using this approach.

The first-year break-even share of the market cannot be determined based on the information provided. The total market size and the expected sales volume of Zap are not specified, making it impossible to calculate the market share at the break-even point.

Step-by-step explanation:

To find the average rate of speed of the wind and the plane, we can use the formula: distance = rate × time.  Therefore, the average rate of speed of the wind is P/3.5, and the average rate of speed of the plane is P.

we have the equation: distance = (P + W) × 1/3. On the return trip against the headwind, the effective speed of the plane is the difference between the plane's rate and the wind's rate: P - W. Given that the time taken is 3/5 hour, we have the equation: distance = (P - W) × 3/5. Since the distance traveled is the same in both cases, we can set up the following equation: (P + W) × 1/3 = (P - W) × 3/5.

On the left side, we have (P + W) × 1/3 = (P/3) + (W/3).
On the right side, we have (P - W) × 3/5 = (3P/5) - (3W/5).
Simplifying further, we have 5W + 9W = 9P - 5P.
Combining like terms, we get 14W = 4P.
Finally, we can divide both sides by 4 to solve for W: W = P/3.5.

The final result is a simplified algebraic expression 3x + 1 that represents the average of 2x, x + 3, and 6x.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The average of 2x, x + 3, and 6x can be represented by the algebraic expression (2x + (x + 3) + 6x)/3.

This expression takes the sum of 2x, x + 3, and 6x, and then divides that sum by 3, which is the number of terms being averaged.

Alternatively, the average can be represented by (2x + x + 6x + 3) / 3 = (9x + 3) / 3 = 3x + 1.

Temperature change for water due to sheer drop is approximately 0.7 °C when Multnomah Falls in the Columbia River has a sheer drop of 543 ft.

Given that,

Multnomah Falls in the Columbia River Gorge has a sheer drop of 543 feet.

We have to find estimate the water temperature change in °F caused by this drop using the steady flow energy equation.

We know that,

Sheer drop is z₁ - z₂ = 543 feet

We required to calculate temperature change that is ∆T caused by this drop using steady flow energy equation says SFEE.

Assuming

Adiabatic flow i.e. Q =0

No work done, i.e. W=0

Neglecting kinetic energies.

Steady flow energy equation is a mathematical expression that states that for a steady flow the net energy at the inlet of control volume is equal to the net energy at the exit of of the control volume.

SFEE is given as,

h₁ + \(\frac{(v_1)^2}{2}\) + gz₁ + Q = h₂ + \(\frac{(v_2)^2}{2}\) + gz₂ + Q -------> equation(1)

Where, h₁ and h₂ enthalpies at inlet and exit of control volume,

v₁ and v₂ are velocities at inlet and exit of control volume (kinetic energies),

z₁ and z₂ are elevation at inlet and exit of control volume (potential energies),  

Q is energy flow into the control volume and

W is work done by control volume.

Neglecting change in kinetic energies ; Q=0; W=0

Then equation (1) will be,

h₁ - h₂ = g(z₂ - z₁)

Cp(ΔT) =  g(z₂ - z₁)

ΔT = \(\frac{g(z_2-z_1)}{Cp}\)

Here,

Value of g is 32.2 feet per second square and value of Cp for water is 25100 feet

Substituting all values we get,

ΔT = \(\frac{32.2(543)}{25000}\)

ΔT = 0.69°C

ΔT = 0.7°C (approximately)

Therefore, Temperature change for water due to sheer drop is approximately 0.7 °C.
