Help me with this math problem, I need someone to guide me through it I don’t understand what I’m supposed to do first

Answers

Answer 1

Answer:

see below

Step-by-step explanation:

The parent function is x^2 which is a parabola at vertex (0,0)

g(x) = ( x+3) ^2

y = f(x + C) C > 0 moves it left

So the parabola is shifted to the left 3 units

h(x) = -( x+3) ^2

y = −f(x)

Reflects it about x-axis

Means flip it about the x axis

1. Find the degrees of freedom for unequal variance test.
2. State the decision rule for 0.01 significance level:
H0:μLC≤μCK; H1:μLC>μCK.
3. Compute the value of the test statistic.

Answers

Answer:

(1) The degrees of freedom for unequal variance test is (14, 11).

(2) The decision rule for the 0.01 significance level is;

If the value of our test statistics is less than the critical values of F at 0.01 level of significance, then we have insufficient evidence to reject our null hypothesis. If the value of our test statistics is more than the critical values of F at 0.01 level of significance, then we have sufficient evidence to reject our null hypothesis.

(3) The value of the test statistic is 0.3796.

Step-by-step explanation:

We are given that you are an expert on the fashion industry and wish to gather information to compare the amount earned per month by models featuring Liz Claiborne's attire with those of Calvin Klein.

The following is the amount ($000) earned per month by a sample of 15 Claiborne models;

$3.5, $5.1, $5.2, $3.6, $5.0, $3.4, $5.3, $6.5, $4.8, $6.3, $5.8, $4.5, $6.3, $4.9, $4.2 .

The following is the amount ($000) earned by a sample of 12 Klein models;

$4.1, $2.5, $1.2, $3.5, $5.1, $2.3, $6.1, $1.2, $1.5, $1.3, $1.8, $2.1.

(1) As we know that for the unequal variance test, we use F-test. The degrees of freedom for the F-test is given by;

[tex]\text{F}_(_n__1-1, n_2-1_)[/tex]

Here, [tex]n_1[/tex] = sample of 15 Claiborne models

[tex]n_2[/tex] = sample of 12 Klein models

So, the degrees of freedom = ([tex]n_1-1, n_2-1[/tex]) = (15 - 1, 12 - 1) = (14, 11)

(2) The decision rule for 0.01 significance level is given by;

(3) The test statistics that will be used here is F-test which is given by;

T.S. = [tex]\frac{s_1^{2} }{s_2^{2} } \times \frac{\sigma_2^{2} }{\sigma_1^{2} }[/tex] ~ [tex]\text{F}_(_n__1-1, n_2-1_)[/tex]

where, [tex]s_1^{2}[/tex] = sample variance of the Claiborne models data = [tex]\frac{\sum (X_i-\bar X)^{2} }{n_1-1}[/tex] = 1.007

[tex]s_2^{2}[/tex] = sample variance of the Klein models data = [tex]\frac{\sum (X_i-\bar X)^{2} }{n_2-1}[/tex] = 2.653

So, the test statistics = [tex]\frac{1.007}{2.653 } \times 1[/tex] ~ [tex]\text{F}_(_1_4,_1_1_)[/tex]

= 0.3796

Hence, the value of the test statistic is 0.3796.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The 95% confidence interval is [tex] [670.03 , 673.97 ] [/tex]

The test statistics is [tex]t = 7.7 [/tex]

The p-value is [tex]p-value = 0[/tex]

The p-value suggests that the null hypothesis is rejected with a high degree of confidence. Hence there is statistically significant evidence that the districts with smaller classes have higher average test score

Step-by-step explanation:

From the question we are told that

The sample size is n = 408

The sample mean is [tex]\= y = 672.0[/tex]

The standard deviation is [tex]s = 20.3[/tex]

Given that the confidence level is 95% then the level of significance is

[tex]\alpha = (100 -95 )\% = 0.05[/tex]

From the normal distribution table the critical value of [tex]\frac{\alpha }{2} = \frac{0.05 }{2}[/tex] is

[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]

Generally the margin of error is mathematically represented as

[tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]

=> [tex]E = 1.96 * \frac{20.3}{\sqrt{408} }[/tex]

=> [tex]E = 1.970[/tex]

Generally the 95% confidence interval is mathematically represented as

[tex]\= y -E < \mu < \= y + E[/tex]

=> [tex] 672.0 -1.970 < \mu < 672.0 +1.970[/tex]

=> [tex] 670.03 < \mu < 673.97[/tex]

=> [tex] [670.03 , 673.97 ] [/tex]

From the question we are told that

Class size small large

[tex]Avg.score(\= y)[/tex] [tex]\= y_1 = 683.7[/tex] [tex]\= y_2 = 676.0[/tex]

[tex]S_y[/tex] [tex]S_{y_1} =20.2[/tex] [tex]S_{y_2} = 18.6[/tex]

sample size [tex]n_1 = 229[/tex] [tex]n_2 = 184[/tex]

The null hypothesis is [tex]H_o : \mu_1 - \mu_2 = 0[/tex]

The alternative hypothesis is [tex]H_a : \mu_1 - \mu_2 > 0[/tex]

Generally the standard error for the difference in mean is mathematically represented as

[tex]SE = \sqrt{\frac{S_{y_1}^2 }{n_1} +\frac{S_{y_2}^2 }{n_2} }[/tex]

=> [tex]SE = \sqrt{20.2^2 }{229} +\frac{18.6^2 }{184_2} }[/tex]

=> [tex]SE = 1.913[/tex]

Generally the test statistics is mathematically represented as

[tex]t = \frac{\= y _1 - \= y_2 }{SE}[/tex]

=> [tex]t = \frac{683.7 - 676.0 }{1.913}[/tex]

=> [tex]t = 7.7 [/tex]

Generally the p-value is mathematically represented as

[tex]p-value = P(t > 7.7 )[/tex]

From the z-table

[tex]P(t > 7.7 ) = 0[/tex]

[tex]p-value = 0[/tex]

From the values we obtained and calculated we can see that [tex]p-value < \alpha[/tex]

This mean that

What value of a makes the solution to the equation 5x-10=3x+a equal to 12

Answers

Answer:

a=-1.2

Step-by-step explanation:

5x-10=3x+a=12

let's first find x:

5x-10=12

add 10 to both sides:

5x=22

divide both sides by 5:

x=4.4

now that we know what x is, we can plug it back into the equation to find a:

3*4.4+a=12

first, simplify both sides:

13.2+a=12

then, subtract 13.2 from both sides:

and our answer is: a=-1.2

Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76 cm^2. Now suppose you are asked to enter the answer to two significant figures. (Note that if you do not round your answer to two significant figures, your answer will fall outside of the grading tolerance and be graded as incorrect.) Write your answer to two significant figures and include the appropriate units

Answers

Answer:

The area of the rectangle is 12 cm² (to two significant figures)

Step-by-step explanation:

To determine the area of a rectangle that is 2.1-cm wide by 5.6-cm long,

The area of a rectangle is given by

Area = l × w

where l is the length

and w is the width

From the question,

l = 5.6 cm

and w = 2.1 cm

Hence, Area of the given rectangle will be

Area = 5.6 cm × 2.1 cm

Area = 11.76 cm²

Now, we will convert the answer to two significant figures

Then,

Area = 12 cm²

Hence, the area of the rectangle is 12 cm² (to two significant figures)

— 7x — бу = — 15 Determine the intercepts of the line.

Answers

Answer:

see below

Step-by-step explanation:

— 7x — бу = — 15

To find the x intercept set y = 0 and solve for x

-7x - 0 = -15

-7x= -15

Divide by -7

-7x/-7 = -15/-7

x = 15/7

The x intercept is (15/7,0)

To find the y intercept set x = 0 and solve for y

o— бу = — 15

— бу= -15

Divide by -6

— бу/-6= -15/-6

у= 5/2

The y intercept is (0,5/2)

this isn’t accurate because they didn’t round the numbers correctly. for example, if a decimal is 7.5, you would usually round it up to 8, so anything higher should also be rounded to 8. the fact they rounded 7.95 to 7 doesn’t make sense as it’s much closer to 8 than it is to 7.
