Answer:

Perimeter = [tex](30-\frac{3}{2}x)[/tex]

Step-by-step explanation:

Width of the rectangle has been given as [tex](5-\frac{1}{4}x)[/tex].

Convert the statement into the algebraic expression,

"Length of the rectangle is twice the width"

Length = 2(Width)

            = [tex]2(5-\frac{1}{4}x)[/tex]

            = [tex]10-\frac{1}{2}x[/tex]

Since perimeter of a rectangle is given by the expression,

Perimeter = 2(Length + Width)

By substituting the values of length and width in the expression,

Perimeter = [tex]2[(5-\frac{1}{4}x)+(10-\frac{1}{2}x)][/tex]

                 = [tex]2(15-\frac{3}{4}x)[/tex]

                 = [tex](30-\frac{3}{2}x)[/tex]

Therefore, expression representing perimeter is [tex](30-\frac{3}{2}x)[/tex].

From Barbie dolls to runway models, women in Western countries are exposed to unrealistically thin and arguably unhealthy body standards for their gender. A body mass index (BMI) between 18.5 and 24.9 is considered healthy. Using a 3D computer avatar, participants built what they considered the ideal body of an adult of their own gender. Below appears a summary of the results for a sample of 40 female heterosexual Caucasian undergraduate students from British universities that had been recruited by the researchers. Mean BMI was recorded to be 18.85 with standard deviation 1.75. Does the data provide evidence that young Caucasian women in British Universities, on average, aim for an unhealthy ideal body type (corresponding to a BMI less than 18.5)? Use α = 0.10.

Required:
a. Construct a 99% confidence interval for the mean BMI for young Caucasian women in British universities using R. Use at least 2 decimals in your answer.
b. Would a 99% CI (for the mean BMI) constructed using a smaller sample than the one used for part a) tend to be wider or narrower? Explain.

Answers

Answer:

(18.1361 ; 19.5639) ;

using a smaller sample will widen the margin

Step-by-step explanation:

Given :

Xbar = 18.85

Standard deviation, s = 1.75

Sample size, n = 40

Confidence interval is obtained using the relation :

Xbar ± Margin of error

Margin of Error = Zcritical * s/ √n

Zcritical at 99% = 2.58

Margin of error = 2.58 * (1.75/√40) = 0.7139

Lower boundary = 18.85 - 0.7139 = 18.1361

Upper boundary = 18.85 + 0.7139 = 19.5639

(18.1361 ; 19.5639)

B.)

The sample size, n being the denominator in the margin error formula increases the error value as it reduces or decreases in value Hence widens the interval. Conversely, increasing the sample size reduces the error margin value and ultimately narrows the interval.

Therefore, using a smaller sample will widen the margin

Answer:

120 square inches.

Step-by-step explanation:

This is a regular octagon. (It has 8 equal sides). You have enough information to find the area of 1 triangle.label the bottom line as 5.Draw two lines from the center to each end of the bottom 5 inch line.That gives you 1 triangle. Find the area of that 1 triangle.

Area = 1/2 b * hb = 5h = 6Area = 1/2 * 5 * 6Area = 15.

Now here's the actual answer.You have 8 such triangles. The area of the octagon is 8 * 15 = 120 square inches.

A). Using a larger down payment often results in lower interest rates on the loan for the vehicle.
B) The amount of money placed upfront on a car loan is usually rebated back to the borrower at the end of the loan.
C) Placing a larger down payment on the loan typically lessens the total amount required to be paid back on the loan.
Eliminate
D) Using a larger down payment creates a larger principal on the loan, meaning the interest paid on the loan will be smaller.
E) Putting down more money upfront on a loan allows more money to be invested elsewhere by the borrower during the length of the car loan.

Write an equation of the line below.

Answers

Answer (assuming it can be in slope-intercept form):

[tex]y = \frac{4}{5} x[/tex]

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula [tex]m = \frac{y_2-y_1 }{x_2-x_1}[/tex] and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:

[tex]m = \frac{4-0}{5-0} \\m = \frac{4}{5}[/tex]

So, the slope is [tex]\frac{4}{5}[/tex].

2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.

3) Now, write the equation of the line in slope-intercept form using the [tex]y = mx + b[/tex] format. The number in place of [tex]m[/tex] represents the slope, so substitute [tex]\frac{4}{5}[/tex] in its place. The number in place of [tex]b[/tex] represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:

[tex]y =\frac{4}{5} x+0\\y = \frac{4}{5} x[/tex]

Answer:

y=4/5x

Step-by-step explanation:

y=mx+b where m=slope and b=y-intercept

In this problem, the slope is 4/5 because m=rise/run.

hope this helped :)

Answer:

B. 5/12

Step-by-step explanation:

2/3 x 5/8 = 10/24

The greatest common factor of 10 and 24 is 2.

Since the GCF is 2,

We divide the numerator and denominator by 2 and get 5/12.

Therefore, the simplified fraction of 10/24 is 5/12.

Consider the line y=7x+4.
Find the equation of the line that is parallel to this line and passes through the point ( -3, 5)
Find the equation of the line that is perpendicular to this line and passes through the point ( -3, 5)

Answers

Answer:

parallel y=7x+26

perpendicular y=1/7x+32/7

Step-by-step explanation:

parallel line have the same slope

y-5=7(x-(-3))

y-5=7(x+3)

y-5=7x+21

y=7x+21+5

y=7x+26

perpendicular slope  is the opposite of the original slope of 7

y-5=-1/7(x-(-3))

y-5=-1/7(x+3)

y-5=-1/7x-3/7

y=-1/7x-3/7+5

y=-1/7x+32/7

 |Z| = |-1.0| < 1.96 at 0.05 level of significance.

The null hypothesis is accepted

The company that produces the drug test claims that less than 14% of the test results are wrong

Step-by-step explanation:

Step(i):-

Given that the population proportion P = 14% =0.14

Given that the sample size 'n' = 382 tests

Given that find a study where 47 out of 382 test results using this test were wrong (either a false positive or a false negative).

Sample proportion

                        [tex]p = \frac{x}{n} = \frac{47}{382} = 0.1230[/tex]

Null hypothesis: H₀ : P = 0.14

Alternative Hypothesis:H₁ : P≠ 0.14

Step(ii):-

Test statistic

              [tex]Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }[/tex]

         [tex]Z = \frac{0.1230-0.14}{\sqrt{\frac{0.14 X0.86}{382} } }[/tex]

       Z = - 1.0

     |Z| = |-1.0| < 1.96 at 0.05 level of significance.

Final answer:-

The null hypothesis is accepted
