<h2>Answer:</h2>

Option: B is the correct answer.

B.  They have the same vertical stretch.

<h2>Step-by-step explanation:</h2>

We are given function f(x) as:

         f(x)=\dfrac{3}{2}|x-7|-2

and function g(x) as:

                g(x)=1.5\ln(x-2)+7

As we know that for any function of the type:

        f(x)=a f(x)

if a>1 then the transformation would be a vertical stretch.

and if 0<a<1 then the transformation is a vertical shrink.

In the given function we see that the function f(x) has a vertical stretch of 3/2=1.5 units and the function g(x) has a vertical stretch of 1.5 units.

Hence, both the functions f(x) and g(x) have the same vertical stretch.

In a survey, 24 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped
erica [24]

Answer:

The 98% confidence interval for the mean amount spent on their child's last birthday gift is between $40.98 and $43.02.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 24 - 1 = 23

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 23 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.98}{2} = 0.99. So we have T = 2.5

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 2.5\frac{2}{\sqrt{24}} = 1.02

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 42 - 1.02 = $40.98.

The upper end of the interval is the sample mean added to M. So it is 42 + 1.02 = $43.02.

The 98% confidence interval for the mean amount spent on their child's last birthday gift is between $40.98 and $43.02.

Find the area of the triangle SHOW WORK
kykrilka [37]

Answer:

The area of triangle is 1263.6 mm².

This is an Equilateral triangle.

Step-by-step explanation:

Given that the area of triangle formula is A = 1/2×base×height. So you have to substitute the values into the formula :

area =  \frac{1}{2}  \times base \times height

Let base = 54mm,

Let height = 46.8mm,

area =  \frac{1}{2}  \times 54 \times 46.8

area =  \frac{1}{2}  \times 2527.2

area = 1263.6 \:  {mm}^{2}

This is the <u>E</u><u>q</u><u>u</u><u>i</u><u>l</u><u>a</u><u>t</u><u>e</u><u>r</u><u>a</u><u>l</u><u> </u><u>t</u><u>r</u><u>i</u><u>a</u><u>n</u><u>g</u><u>l</u><u>e</u> because all sides of the triangle are <u>e</u><u>q</u><u>u</u><u>a</u><u>l</u>.

atroni [7]

Answer:

5.70 < X < 5.89

Step-by-step explanation:

Z = ±1.40507156

z = (x - μ)/σ

1.40507156 = (x - 5.8)/.07

5.70 < X < 5.89
