[tex]B = 102^\circ[/tex]

[tex]C = 102^\circ[/tex]

Step-by-step explanation:

Given

The attached image

Required

Find A, B and C

Because the sides of the crosswalk are parallel and the sidewalks are also parallel, then the following relationships exist

[tex]A = 78^\circ[/tex] ---- alternate interior angles

[tex]B = C[/tex]   ---- alternate interior angles

To solve for B, we have:

[tex]B + 78 = 180[/tex] --- the sum of the base angles

[tex]B = 180 - 78[/tex]

[tex]B = 102^\circ[/tex]

Recall that:

[tex]B = C[/tex]

[tex]C = 102^\circ[/tex]

Complete question :

A data set includes data from student evaluations of courses. The summary statistics are nequals92​, x overbarequals4.09​, sequals0.55. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim.

Answer:

H0 : μ = 4.25

H1 : μ < 4.25

T = - 2.79

Pvalue =0.0026354

we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%

Step-by-step explanation:

Given :

n = 92​, xbar = 4.09​, s = 0.55 ; μ = 4.25

H0 : μ = 4.25

H1 : μ < 4.25

The test statistic :

T = (xbar - μ) ÷ s / √n

T = (4.09 - 4.25) ÷ 0.55/√92

T = - 0.16 / 0.0573414

T = - 2.79

The Pvalue can be obtained from the test statistic, using the Pvalue calculator

Pvalue : (Z < - 2.79) = 0.0026354

Pvalue < α ; Hence, we reject the Null

Thus, we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%

Answer:

Step-by-step explanation:

The null and alternative hypotheses are:

Null hypothesis: The population mean of student course evaluations is equal to 4.25.

Alternative hypothesis: The population mean of student course evaluations is not equal to 4.25.

The significance level is 0.01, so the test will be a two-tailed test.

The test statistic is calculated as:

t = (x - μ) / (s / √n) = (4.18 - 4.25) / (0.54 / √97) = -2.63

The degrees of freedom for the t-distribution is n-1 = 96. Using a t-table or a calculator, the P-value for a two-tailed test with 96 degrees of freedom and a t-value of -2.63 is approximately 0.010.

Since the P-value (0.010) is less than the significance level (0.01), we reject the null hypothesis. We have sufficient evidence to conclude that the population mean of student course evaluations is not equal to 4.25.

In other words, the data provides strong evidence to suggest that the average student course evaluation rating is significantly lower than 4.25.

[tex]-\sqrt{5}[/tex] x 2 = [tex]-2\sqrt{5}[/tex]

[tex]\sqrt{5}[/tex] x 2 = [tex]2\sqrt{5}[/tex]

[tex]\sqrt{5}[/tex] x [tex]-\sqrt{5}[/tex] = -5

4 [tex]-2\sqrt{5}[/tex] + [tex]2\sqrt{5}[/tex] - 5 = ?

the radicals cancel out and 4 -5 = -1

Step-by-step explanation:

GCF of 4 and 6 is 12

1/6 = 2/12

3/4 = 9/12

4 + 1 = 5

2/12 + 9/12 = 11/12

5 11/12

Answer:

Step-by-step explanation:

First you want to make the denominators in the fractions the same number. To do so, we need to multiply both the numerators and the denominators. Do this until the denominators are the same.

[tex]\frac{1}{6} *\frac{4}{4} = \frac{4}{24}[/tex]

[tex]\frac{3}{4} *\frac{6}{6} = \frac{18}{24}[/tex]

Now add

[tex]4\frac{4}{24} + 1\frac{18}{24} = 5\frac{22}{24}[/tex]

After adding, you need to multiply the whole numbers by the denominator and add that number to the numerator.

[tex]5*24=120[/tex]

[tex]\frac{120}{24} +\frac{22}{24} = \frac{142}{24}[/tex]

Finally simplify

[tex]\frac{142}{24} / \frac{2}{2} = \frac{71}{12}[/tex]

Answer:

One woman receive 20 eggs

And the other receive 40 Egss

Explanation:

So the ratio is 1:2 so we gonna add them to get the total so 1+2=3

To find each amount divide each by the total so 1/3 and 2/3

To find the first amount

1/3×60=20

To find the other amount you can either subtract

60-20=40

or

2/3×60=40

One woman receive 20 eggs and the other receive 40 eggs.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

So the ratio is 1:2 so we have to add them to get the total.

So 1+2=3

In order to find each amount divide each by the total.

So 1/3 and 2/3

The first amount,

1/3 × 60 = 20

The other amount,

60-20=40

or

2/3 × 60 = 40

Thus, One woman receive 20 eggs and the other receive 40 eggs.

Step-by-step explanation: a p e x

The negative angle that is equivalent to 265° would be equal to negative 85 degrees.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

The negative angle is equivalent to 265°.

We know that the sum of angles is always 180

So,

we will subtract the angle 180 from the angle of 265 degrees.

265 - 180

= 85°
