Answer:

\(x=-\frac{41}{6}\)

Step-by-step explanation:

Pay attention to the two tick marks. This indicates that those sides are congruent to each other and so will the angles on the bottom and top. Therefore, we can set up the equation \(137+2(-3x+1)=180\) and solve for x:

\(137+2(-3x+1)=180\)

\(137+(-6x+2)=180\)

\(137-6x+2=180\)

\(139-6x=180\)

\(-6x=41\)

\(x=-\frac{41}{6}\)

False. A linear transformation is not completely determined by its effect on the columns of the identity matrix. While the columns of the identity matrix form a basis for the vector space, and determining their images under the transformation provides some information about the transformation, it does not provide a complete characterization.

A linear transformation is defined by its action on all vectors in the vector space, not just the basis vectors. The transformation can have different effects on vectors that are not in the span of the columns of the identity matrix. Therefore, knowing only the effect on the basis vectors does not fully determine the transformation.

To completely determine a linear transformation, one needs to know its effect on a set of linearly independent vectors that span the entire vector space. This set of vectors does not have to be restricted to the columns of the identity matrix. The transformation can be uniquely defined by specifying its values on these vectors, and then extended linearly to the entire vector space.

If the speed of the train was 55 miles per hour faster than the girls walked, the distance covered was 240 miles.

Let the distance covered be d miles. Given that the train made the trip in 4 hours and the girls walked it in 48 hours. Using the formula;

distance = speed x time.

The speed of the girls can be represented by s while the speed of the train can be represented by s + 55 mph. Hence;

distance covered by the train = (s + 55) × 4 miles and distance covered by the girls = s × 48 miles

Since both distances are equal, we can say:

(s + 55) × 4 = s × 48

Simplifying this equation;

4s + 220 = 48s

44s = 220

s = 5 miles per hour

Substituting s into any of the equations for distance,

Distance covered by the train = (s + 55) × 4 = (5 + 55) × 4 = 240 miles.

Distance covered by the girls = s × 48 = 5 × 48 = 240 miles

Therefore, the distance covered was 240 miles.

Answer:

Range is between -7 and 8

-7<y<8

Step-by-step explanation:

Range means series of number between lowest and highest output(y-axis) of a function.

Notice on the graph, the lowest y you can get is -7 and highest is 8. Other numbers are in between.  

Thus,  the range is in between of -7 and 8.

The size of the crowd that fit 5 feet deep and 1 mile long on one side of the street is 8448.

Given:

in 5ft by 5ft = 25ft^2, there can be 1 person

A normal street is 30ft wide

Then, if we want the width such that is 5 ft deep (from both sides)

Then we should subtract two times 5 ft:

30ft - 5ft - 5ft = 20ft.

Now the length is 1 mile.

and 1 mile = 5280 ft

Then the area is:

There are 5280 feet in a mile. So, that's exactly 1056 lengths of 5 feet each.  To estimate, 5250 is 5×1050 lengths

In each 5 ft by 5 ft square, 8 people fit comfortably.  So, estimating, 8×1050 is 8400

To check (or verify),   8(5280/5) = 8448 exactly.    Our estimate is close enough

Hence we get the required answer.

The point of diminishing returns is (20.98, 21247.3).

The point of diminishing returns occurs when the marginal cost of producing an extra unit of output exceeds the marginal revenue generated from selling that unit. Mathematically, it is the point at which the derivative of the production function equals zero and the second derivative is negative.

Given the polynomial function N(x) of degree 3, we can find the point of diminishing returns by finding the critical points where the first derivative equals zero and evaluating the second derivative at those points.

The derivative of N(x) is N'(x) = -18x² + 360x + 2250. To find the critical points, we set N'(x) = 0:

0 = -18x² + 360x + 2250

Dividing by -18 simplifies the equation:

0 = x² - 20x - 125

Using the quadratic formula, we find the solutions to the equation:

x₁,₂ = (20 ± √(20² - 4(1)(-125))) / 2(1)

x₁,₂ = 10 ± 5√5

Thus, the two critical points of N(x) are at x = 10 - 5√5 and x = 10 + 5√5.

To determine the point of diminishing returns, we evaluate the second derivative N''(x) = -36x + 360 at these critical points:

N''(10 - 5√5) = -36(10 - 5√5) + 360 ≈ -264.8

N''(10 + 5√5) = -36(10 + 5√5) + 360 ≈ 144.8

From the evaluations, we find that N''(10 + 5√5) is negative while N''(10 - 5√5) is positive. Therefore, the point of diminishing returns corresponds to x = 10 + 5√5.

To find the corresponding y-coordinate (N(10 + 5√5)), we can substitute the value of x into the original function N(x).

Hence, the point of diminishing returns is approximately (20.98, 21247.3).

Mean is a measurement of a probability distribution's central tendency along the median and mode. It also goes by the name "anticipated value."

Given:

Cathy has obtained a sample mean of 0. 7 and, but she cannot remember if the sample size was 20 or 25,

Calculate the sample size as shown below,

As we know that the variance would be positive,

18.84 rounded to the nearest tenth is 18.8.

Rounding to place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

We can see that round a number to the nearest tenth, we need to look at the digit in the hundredth place. In this case, the number is 18.84.

Therefore, digit in the hundredth place is 4.

If the digit in the hundredth place is less than 5, we round down to the previous tenth. If it is 5 or greater, we round up to the next tenth.

Since 4 is less than 5, we round down. Therefore, 18.84 rounded to the nearest tenth is 18.8.

The exact value of sin(α + β) is -16/65.

To find the exact value of sin(α + β), we can use the trigonometric identities and the given information about the values of sinα and sinβ.

We are given:

sinα = 3/5 (α in quadrant I)

sinβ = 5/13 (β in quadrant II)

Let's use the sum formula for sine:

sin(α + β) = sinα * cosβ + cosα * sinβ

To evaluate sinα, we need to find cosα using the Pythagorean identity:

sin²α + cos²α = 1

Given sinα = 3/5, we can solve for cosα:

(3/5)² + cos²α = 1

9/25 + cos²α = 1

cos²α = 1 - 9/25

cos²α = 16/25

cosα = ± √(16/25)

cosα = ± 4/5

Since α is in quadrant I, cosα is positive:

cosα = 4/5

Similarly, we need to find cosβ using the Pythagorean identity:

sin²β + cos²β = 1

Given sinβ = 5/13, we can solve for cosβ:

(5/13)² + cos²β = 1

25/169 + cos²β = 1

cos²β = 1 - 25/169

cos²β = 144/169

cosβ = ± √(144/169)

cosβ = ± 12/13

Since β is in quadrant II, cosβ is negative:

cosβ = -12/13

Now, substitute the values of sinα, cosα, sinβ, and cosβ into the sum formula for sine:

sin(α + β) = (3/5) * (-12/13) + (4/5) * (5/13)

sin(α + β) = -36/65 + 20/65

sin(α + β) = -16/65

Therefore, the exact value of sin(α + β) is -16/65.

Answer:

A 0.4 as the tax percent.

Step-by-step explanation:

The correlation analysis indicates a moderate positive relationship between Column X and Column Y.

To perform correlation analysis, we can use the Pearson correlation coefficient (r) to measure the linear relationship between two variables, in this case, Column X and Column Y. The value of r ranges from -1 to 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.

Here are the steps to calculate the correlation coefficient:

Calculate the mean (average) of Column X and Column Y.

Mean(X) = (10+6+39+24+35+12+33+32+23+10+16+16+35+28+5+22+12+44+15+40+46+35+28+9+9+8+35+15+34+16+19+17+21) / 32 = 24.4375

Mean(Y) = (37+10+18+12+11+34+26+9+42+24+40+1+39+24+42+7+17+17+27+47+35+14+38+18+17+22+12+30+18+43+24+45+24) / 32 = 24.8125

Calculate the deviation of each value from the mean for both Column X and Column Y.

Deviation(X) = (10-24.4375, 6-24.4375, 39-24.4375, 24-24.4375, ...)

Deviation(Y) = (37-24.8125, 10-24.8125, 18-24.8125, 12-24.8125, ...)

Calculate the product of the deviations for each pair of values.

Product(X, Y) = (Deviation(X1) * Deviation(Y1), Deviation(X2) * Deviation(Y2), ...)

Calculate the sum of the product of deviations.

Sum(Product(X, Y)) = (Product(X1, Y1) + Product(X2, Y2) + ...)

Calculate the standard deviation of Column X and Column Y.

StandardDeviation(X) = √[(Σ(Deviation(X))^2) / (n-1)]

StandardDeviation(Y) = √[(Σ(Deviation(Y))^2) / (n-1)]

Calculate the correlation coefficient (r).

r = (Sum(Product(X, Y))) / [(StandardDeviation(X) * StandardDeviation(Y))]

By performing these calculations, we find that the correlation coefficient (r) is approximately 0.413. Since the value is positive and between 0 and 1, we can conclude that there is a moderate positive relationship between Column X and Column Y.
