One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cyl
mojhsa [17]

The correct equation is:

216 = \frac{7}{8} \times x - 8

The volume of second cylinder is 256 centimeter cubed

<em><u>Solution:</u></em>

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

216 = \frac{7}{8} \times x - 8

216 = \frac{7x}{8}-8\\\\216 = \frac{7x-64}{8}\\\\7x - 64 = 8 \times 216\\\\7x - 64 = 1728\\\\7x = 1728 + 64\\\\7x = 1792\\\\Divide\ both\ sides\ by\ 7\\\\x = 256

Thus the volume of second cylinder is 256 centimeter cubed

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
