Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is B, 4.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that the table represents the relationship between the weight of apples purchased and the total cost of the apples.

Apple Cost Weight (lb)      Total cost ($)

              1                                    2

              4                                   8

              6                                   12

             10                                  20

Now, we look at the table in the first row the weight of the apple is 1lb and the cost is $2. But, when the weight is increased by 4 in the next row the price became $8.

Thus, it can be concluded that When the weight of apples is increased by a factor of 4, then the factor by which the total cost increase is 4.

Hence, the correct option is B, 4.

The rate of change of the area of the square with respect to time, da/dt, can be expressed in terms of the rate of change of the perimeter, dp/dt, as (P/2) * dp/dt.

To find da/dt, the rate of change of the area of a square with respect to time, in terms of dp/dt, the rate of change of the perimeter, we can apply the chain rule of differentiation. The first step is to express the area and perimeter of the square in terms of x. Then, differentiate both sides of the equation and solve for da/dt.
Let's start by expressing the area and perimeter of the square in terms of x. The area of a square is given by A = x^2, and the perimeter is given by P = 4x.
Next, we differentiate both sides of the equation with respect to time, t. Using the chain rule, we have:
dA/dt = dA/dx * dx/dt
The derivative dA/dx represents the rate of change of the area with respect to the side length x, which is 2x. The derivative dx/dt represents the rate of change of the side length with respect to time, which we'll denote as dp/dt.
Substituting these values into the equation, we get:
dA/dt = 2x * dp/dt
Finally, we can express da/dt in terms of dp/dt by substituting 4x for P:
dA/dt = (P/2) * dp/dt
Therefore, the rate of change of the area of the square with respect to time, da/dt, can be expressed in terms of the rate of change of the perimeter, dp/dt, as (P/2) * dp/dt.

Answer:

  (a) -48

Step-by-step explanation:

You want the solution to the equation 1/6(x +18) = -5.

The first step to solving this can be to multiply both sides by 6, eliminating the fraction:

  x +18 = -30

The second step can be to isolate the variable by subtracting 18 from both sides.

  x = -48

The solution is x = -48.

Additional comment

Sometimes you may want to simplify the equation before you start the solution process. Here, you can also start by eliminating parentheses:

  1/6x +3 = -5

Now, subtracting 3 gives ...

  1/6x = -8

Finally, multiplying by 6, we have ...

  x = -48

1/5

Step-by-step explanation:

Answer: 8.1

Step-by-step explanation:

Answer:

The equation is  \(-\frac{1}{8}\) x = \(-\frac{3}{4}\)

Step-by-step explanation:

The Equation is formed from two sides equal to each other

∵ One eighth means \(\frac{1}{8}\)

∴ Negative one eighth means  \(-\frac{1}{8}\)

→ Assume that the number is x

∵ "of" means times

∴ Negative one eighth of a number = \(-\frac{1}{8}\) × (x)

∴ Negative one eighth of a number = \(-\frac{1}{8}\) x

∵ Negative one eighth of a number is \(-\frac{3}{4}\)

→ "is" means equal, so the left side is \(-\frac{1}{8}\) x and the right side is \(-\frac{3}{4}\)

∴  \(-\frac{1}{8}\) x = \(-\frac{3}{4}\) ⇒ Equation

∴ The equation is  \(-\frac{1}{8}\) x = \(-\frac{3}{4}\)

Note that in the above case,  the p-value for the hypothesis test is approximately 0.999.

To find the test statistic (t) and the p-value for the given hypothesis test, we can use the following formula  -

t = (sample mean - hypothesized mean) / (sample standard deviation / √n)

Thus

t = ($56,500 - $55,000) / ($3,750 / √61)

≈ 3.77

Using the t-table with   60 degrees of freedom (corresponding to n-1),we find that the critical value for a right-tailed test with α = 0.05 is approximately 2.632

Comparing the   test statistic to the critical value,we see that

t = 3.77 > 2.632

This  indicates that the test statistic falls   in the critical region.

Next,we need to find the p-value   associated with the test statistic.

Since t = 3.77 falls in the right tail of   the t-distribution,we can use the t-table to estimate the p-value.

Looking at the t-table,the closest value to t = 3.77 with 60 degrees of freedom is 3.733, which   corresponds to a probability of 0.0014.

Since the   p -value is the probability of observing a test statisticas extreme or more extreme than the one obtained, we take the complement of the probability  - 1 - 0.0014

= 0.9986.

Therefore, the   p-value for the hypothesis test isapproximately 0.999

The total amount of money in the purse was approximately 23 ducats. A man finds a purse with an unknown number of ducats in it. After he spends 1/4, 1/5, and 1/6 of the amount, 9 ducats remain. To find the initial amount in the purse, let's represent it as "x".

He spent (1/4)x, (1/5)x, and (1/6)x. The sum of these fractions plus the remaining 9 ducats equals the total amount:

(1/4)x + (1/5)x + (1/6)x + 9 = x

To solve this equation, first find a common denominator for the fractions, which is 60. Rewrite the equation with the common denominator:

(15/60)x + (12/60)x + (10/60)x + 9 = x

Combine the fractions:

(37/60)x + 9 = x

Now, isolate x on one side of the equation:

9 = (23/60)x

To find x, divide both sides by (23/60):

x = 9 / (23/60)

x = 9 * (60/23)

x = 540/23

Since x represents the number of ducats, it should be a whole number. So, we round it to the nearest whole number:

x ≈ 23

Therefore, there were approximately 23 ducats in the purse initially.

ab = x, bc = y, and ca = 2x

om = 5

The scale factor from abc to mno is 0.5.

So, we have:

0.5 * ca = om

Substitute om = 5

0.5 * ca = 5

Divide both sides by 0.5

ca = 10

Recall that:

ca = 2x

So, we have:

2x = 10

Divide by 2

x = 5

The probability that none of the households are tuned to 50 Minutes is 0.4693. The probability that at least one household is tuned to 50 Minutes is 0.5307. The probability that at most one household is tuned to 50 Minutes is 0.5307. Since the probability of at most one household being tuned to 50 Minutes is relatively high (0.5307), it suggests that the 24% share value might be inaccurate.

To find the probability that none of the households are tuned to 50 Minutes, we need to calculate the complement of at least one household being tuned to the show. The complement is 1 minus the probability of at least one household tuning in. Therefore,

P(none) = 1 - P(at least one) = 1 - 0.5307 = 0.4693.

Similarly, to find the probability of at least one household being tuned to 50 Minutes, we can calculate the complement of none of the households tuning in. This is simply 1 minus the probability of none of the households tuning in. Therefore, P(at least one) = 1 - P(none) = 1 - 0.4693 = 0.5307.

The probability that at most one household is tuned to 50 Minutes is the sum of the probabilities of none and only one household tuning in. Since the probability of at least one household tuning in is 0.5307, the probability of at most one household tuning in is also 0.5307.

Since the probability of at most one household being tuned to 50 Minutes is relatively high (0.5307), it suggests that the 24% share value might be inaccurate. If the actual share value were 24%, we would expect a lower probability of at most one household tuning in. However, since the probability is relatively high, it indicates that the share value might be wrong or inaccurate. Further investigation or a larger sample size might be necessary to confirm the accuracy of the share value.
