Answer:

A is the correct answer.

Step-by-step explanation:

- B, C, and D are wrong because those only move the position of the shape, which means they are still congruent.

- 1/7x means the shape will get smaller and therefore not be congruent.

- Congruent means they have the same size and shape. All have the same size and shape, but A and therefore that is the correct answer pertaining to this problem.

- Hope this helps! if you need a further explanation or help on any other problems please let me know. I would be glad to help anytime.

Is the national crime rate really going down? Some sociologists say yes! They say that the reason for the decline in crime rates
anygoal [31]

Answer:

a) Level of significance \alpha = 0.01

b) Standard normal

p = 0.75

Z = 0.62

c)  

P = 0.5352

d)  

P > \alpha

e) We fail to reject null hypothesis  

Step-by-step explanation:

Let us say

The null hypothesis H_0 is p= 0.70 which means that Probability of arresting male of age ranging between 15 to 34 years is 0.7

Alternate hypothesis H_1 is p not equal to 0.7 which means that Probability of arresting male of age ranging between 15 to 34 years is not equal to 0.7

a) For 1% level of significance \alpha = 0.01

b) Standard normal

n_p > 5\\n_q >5

p = \frac{24}{32} = 0.75

Z = \frac{(0.75-0.70)}{\sqrt{\frac{(0.7*0.3)}{32} } }  = 0.62

c)  

P = 2 * 0.2676 = 0.5352

d)  

P > \alpha

e) We fail to reject null hypothesis  

Hence, there is not enough data to prove that at 1% level of significance the probability of number of male arrested between age 15-34 is  0.70

The diameter of the cone is 6 inches. It’s height is 4 inches. What is its slant height?
Kisachek [45]

Answer:

5 inches

Step-by-step explanation:

As the height is perpendicular to the base, the radius and the height form a right angle, creating a right triangle where the slant height is the hypotenuse, thus:

(height)^2+(radius)^2=(slant\:height)^2

4^2+(6/2)^2=(slant\:height)^2

16+9=(slant\:height)^2

25=(slant\: height)^2

5=slant\: height

In conclusion, the slant height of the cone is 5 inches. See below for a visual.

The perimeter of a rectangle is 34 units. Its width is 6.5 units. What is its length?
andreyandreev [35.5K]
If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5

Need help asap<br> solve for x using cross multiplication 5x over 7= 2x over 3
Alona [7]

Answer:

0.4

step-by-step explanation

5x times 3 = 7 times 2x-4

first, you divide both sides by 2x

2.5x times 3 = 7-4

then, divide both sides by three

2.5x = 1

lastly, divide both sides by 2.5

x = 0.4
