Hazel plans to mow her neighbors' yards to earn money. she charges a base fee of $25 and $7 for every hour she mows. the amount
bogdanovich [222]

The function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.

<h3>What is a linear function?</h3>

The term linear function refers to a function that yields a straight line graph when it is plotted. Now we know that a linear function would not contain an exponent that is greater than one.

In this case, we know that the question states that she charges a base fee of $25 and $7 for every hour she mows thus the function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.

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
