Answer:

D. ASA

Step-by-step explanation:

We are given the measure of angle C, the side BC, and the measure of angle B

So we are given an angle, a side, then an angle

Answer:

The correct answer is option C.   AAS

Step-by-step explanation:

From the figure we can see that, two triangles,

ΔABC and ΔBCD

<u>To find the correct option</u>

From figure we can see that,

From ΔABC and ΔBCD we get,

<A = <D  

<C = <B and side BC is common for both the triangles ΔABC and ΔBCD

The order of congruence is

angle, angle and side AAS

The correct answer is option C.   AAS

If p stays constant and u is doubled what happens to e? given U=EP
Stolb23 [73]

We are given the expression:

U = E * P

 

The equality symbol “ = “ means that for all cases, the value of U and E * P must always be equal. This means that whatever happens on the left side, must equally happen on the right side.

 

So what this actually means is that, if we double U so we must also double the expression E * P, that is:

2 U = 2 (E * P)

 

However since P stays constant in the process, therefore only E is changed, hence:

2 U = P * 2 E

 

So we can see that E is also doubled.

Employees from A and company B receive annual bonuses. What information would you need to test the claim that the difference in
lyudmila [28]

Answer:

1. The required information are

The average annual bonuses, \bar {x}_1 received by employees from company A

The average annual bonuses, \bar {x}_2 received by employees from company B

The standard deviation, σ₁, of the average annual bonuses for employees from company A

The standard deviation, σ₂, of the average annual bonuses for employees from company A

The number of employees in company A, n₁

The number of employees in company B, n₂

2. The null hypothesis is H₀: \bar {x}_1 - \bar {x}_2 ≤ 100

The alternative hypothesis is Hₐ: \bar {x}_1 - \bar {x}_2 > 100

Step-by-step explanation:

1. The required information are

The average annual bonuses, \bar {x}_1 received by employees from company A

The average annual bonuses, \bar {x}_2 received by employees from company B

The standard deviation, σ₁, of the average annual bonuses for employees from company A

The standard deviation, σ₂, of the average annual bonuses for employees from company A

The number of employees in company A, n₁

The number of employees in company B, n₂

2. The null hypothesis is H₀: \bar {x}_1 - \bar {x}_2 ≤ 100

The alternative hypothesis is Hₐ: \bar {x}_1 - \bar {x}_2 > 100

The z value for the hypothesis testing of the difference between two means is given as follows;

z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})}{\sqrt{\frac{\sigma_{1}^{2} }{n_{1}}-\frac{\sigma _{2}^{2}}{n_{2}}}}

At 0.5 level of significance, the critical z_\alpha = ± 0

The rejection region is z > z_\alpha and z < -z_\alpha

Therefore, the value of z obtained from the relation above more than or less than 0, we reject the null hypothesis, and we fail to reject the alternative hypothesis.
