In the given case, the population is assumed to have a normal distribution.

When creating a confidence interval for the population mean with a sample size of 100, the population is taken to have a normal distribution. This is due to the Central Limit Theorem, which asserts that regardless of the population distribution's form, the distribution of the sample means approaches a normal distribution as the sample size increases.

Therefore, it is safe to infer that the population mean is normally distributed when the sample size is large enough, for instance, n>30. Additionally, it is also ideal to conclude that the population mean has a normal distribution since a sample size of 100 is greater than 30.

The numbers in table are in proportion. Therefore, option B is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Here,

From the table A:

1/5 = 3/15 = 5/20 = 7/28

1/5 = 1/5 ≠ 1/4 = 1/4

Here, numbers are not in proportion.

From the table B:

The exponential depreciation rate to the nearest tenth of a percent is -0.2%. 

we need to use the exponential decay formula to find exponential rate.

A = A0 * e^(-rt)

where:

A0 = initial value of car (52,000)

A = final price of the car (45,000)

t = elapsed time (32 months)

r = exponential depreciation rate

Rearrange the formula to solve for the exponential depreciation rate "r".

r = -ln(A/A0) / t

Insert value:

r= -ln(45,000 / 52,000) / 32

r = -0.067115074/32

r = -0.002097288

The exponential depreciation rate, expressed as a percentage to the nearest tenth of a percent, is obtained by multiplying by 100.

r = -0.002097288 * 100

r = -0.21D

Answer: 126

Step-by-step explanation: Given that the median is the middle number in a sorted, ascending, or descending list of numbers and can be more descriptive of that data set than the average. We know that we need to put the numbers in order from greatest to least or least to greatest first.

Step 1: Ordering the numbers (from least to greatest)

98,118,121,126,127,132,134

Step 2: Finding the value in the middle

98,118,121,  126  ,127,132,134

We now know that 126 is the median number of people served.

Answer: 126 is the median number of people served.

Step-by-step explanation:

The median is found by arranging the data points in a set from lowest to greatest. Once this is done, if there are an odd number of data points, simply find the number in the middle. If there is an even number, find the average of the two middle numbers. Here, you would arrange the numbers as such, 98,118,121,126,127,132,134. Once this is done, since there are seven lines (an odd number of data points, therefore), figure out which number is in the middle, and here it is 126. Hence, the median is 126 (people)

The artist wants to paint a canvas that is proportional to the photograph, which measures 4 inches by 5 inches.

To calculate the proportionality, we will use the formula for converting inches to centimeters. 1 inch is equal to 2.54 centimeters. Therefore, 4 inches is equal to 10.16 centimeters and 5 inches is equal to 12.7 centimeters. Therefore, the artist should purchase canvases that are 10.16 centimeters by 12.7 centimeters in size. This will correspond to the following canvas prices: $6.43, $11.65, $18.47, and $22.80. By purchasing these canvases, the artist will ensure that the painting is proportional to the photograph.

According to the Pythagorean Theorem 1. b = 122. a = 1/4 for more detail scroll down.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. The theorem can be written as an equation: c^2 = a^2 + b^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

1. To use the Pythagorean theorem to find the length of side b, you can use the equation: c^2 = a^2 + b^2. In this case, c = 15 and a = 9, so you can substitute those values into the equation and solve for b:

15^2 = 9^2 + b^2

225 = 81 + b^2

b^2 = 225 - 81

b^2 = 144

b = sqrt(144)

b = 12

2. In the second case a is unknown and the other two sides are in fraction form, so we can use Pythagorean theorem to find the value of a.

The equation is c^2 = a^2 + b^2

(5/12)^2 = a^2 + (4/12)^2

25/144 = a^2 + 16/144

a^2 = 9/144

a = sqrt(9/144)

a = sqrt(1/16)

a = 1/4

The volume of the tetrahedron with base being the triangle with vertices (0,0), (1,0) and (0,1) and fourth vertex lying above the point (0,0) at height 1 can be found by evaluating the triple integral $\int_0^1 \int_0^{1-x} \int_0^{1-x-y} 1\,dz\,dy\,dx$, which evaluates to $\frac{1}{6}$. Therefore, the volume of the tetrahedron is $\frac{1}{6}$.

The integral that represents the volume of the tetrahedron is given by:

$$\int_0^1 \int_0^{1-x} \int_0^{1-x-y} 1\,dz\,dy\,dx$$

Evaluating the integral, we get:

$$\int_0^1 \int_0^{1-x} \int_0^{1-x-y} 1\,dz\,dy\,dx = \int_0^1 \int_0^{1-x} (1-x-y)\,dy\,dx = \int_0^1 \frac{1}{2} (1-x)^2\,dx = \frac{1}{6}$$

Therefore, the volume of the tetrahedron is $\frac{1}{6}$.

We first set up the integral that represents the volume of the tetrahedron. The integral is a triple integral, so it can be written as $\int_0^1 \int_0^{1-x} \int_0^{1-x-y} 1\,dz\,dy\,dx$. This integral is the volume of a 3-dimensional region enclosed by the limits $x \in [0,1]$, $y \in [0,1-x]$, and $z \in [0,1-x-y]$. This region is exactly the same as the volume of the tetrahedron because it is the same 3-dimensional region.

Next, we evaluate the integral. First, we integrate with respect to $z$, which gives us $\int_0^1 \int_0^{1-x} (1-x-y)\,dy\,dx$. Then, we integrate with respect to $y$, which gives us $\int_0^1 \frac{1}{2} (1-x)^2\,dx$. Finally, we integrate with respect to $x$, which gives us $\frac{1}{6}$. Therefore, the volume of the tetrahedron is $\frac{1}{6}$.

The volume of the tetrahedron with base being the triangle with vertices (0,0), (1,0) and (0,1) and fourth vertex lying above the point (0,0) at height 1 can be found by evaluating the triple integral $\int_0^1 \int_0^{1-x} \int_0^{1-x-y} 1\,dz\,dy\,dx$, which evaluates to $\frac{1}{6}$.

The surface area S is given by the definite integral of the function :

|r(t) X r'(t)| over the interval [1], which can be approximated by numerical integration methods.

To find the surface area of the surface generated by the given equations, we need to first find the cross-sectional area of the surface at every point of t and then integrate it over the interval. To do this, we need to find the vector r(t) = (x(t),y(t)) and its derivative r'(t) = (x'(t),y'(t)) which gives the tangent vector to the curve at t. The cross-sectional area of the surface at t is given by the magnitude of the vector cross product of the vectors r(t) and r'(t) and is written as |r(t) X r'(t)|. Then the surface area S is given by the definite integral of this cross-sectional area over the interval [1].

The definite integral can be solved analytically or numerically, however, the final answer would be the integration of the function |r(t) X r'(t)| over the interval [1], which is not possible to solve analytically, so we use numerical integration methods.

The medians of a triangle connect the midpoints of each side and intersect at the centroid of the triangle.

Medians of a triangle are lines that connect the midpoints of each side of the triangle to the opposite vertex. This means that they divide the triangle into two halves, each with an area that is equal to half of the area of the entire triangle. The medians of a triangle with vertices (a1, a2, a3) intersect at a point known as the centroid of the triangle, which is located at the intersection of the three medians. The centroid can be found by taking the average of the three vertices, or by finding the intersection of the three medians. The centroid is the point at which the three medians of the triangle intersect and is the center of gravity for the triangle. In other words, it is the point that all three medians will intersect at.

The y-intercept of the given line is 100.

What is the y-intercept?

The y-intercept is the point at which the line crosses the y-axis, which occurs when x = 0. To find the y-intercept, we can plug in x = 0 into the equation of the line.

We can write the equation of the line in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

We can find the slope m using the point slope formula:

m = (y2 - y1) / (x2 - x1) = (148-100)/(42-0) = 48/42 = 4/3

Now we can substitute the point (0,100) into the equation of the line:

y = (4/3)x + b

100 = (4/3) * 0 + b

b = 100

So the y-intercept is (0,100)
