MATH QUESTION : WORTH 45 PTS
trapecia [35]

y ≤ x − 5

y ≥ −x − 4


This is a check and see type of problem.


if x=5

y ≤ 5 − 5      y≤ 0    

y ≥ −5 − 4     y ≥-9

-9≤ y  ≤ 0

-2 works   so (5,-2) is a solution


if x= -5

y ≤ -5 − 5      y≤ -10    

y ≥ 5 − 4     y ≥1

no solution

Choice B (5,-2)

48% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually
oksian1 [2.3K]

Answer:

There is no sufficient evidence to support the executive claim

Step-by-step explanation:

From the question we are told that

     The  population proportion is  p =  0.48

      The  sample proportion is  \r p  =  0.45

       The sample  size is  n  =  300

       The  level of significance is \alpha  =  0.02

The null hypothesis is  H_o  :  p=  0.48

The  alternative hypothesis is  H_a  :  p \ne  0.48

   Generally the test statistics is mathematically evaluated as

           t =  \frac{\r p  -  p  }{ \sqrt{ \frac{p(1 -  p )}{n} } }

=>        t =  \frac{0.45   -  0.48   }{ \sqrt{ \frac{0.48 (1 -  0.48 )}{300} } }

=>       t =  -1.04

The  p-value is mathematically represented as

     p-value  =  2P(z  >  |-1.04|)

Form the z-table  

                 P(z  >  |-1.04|)  =   0.15

=>   p-value  =  2 * 0.15

=>   p-value  = 0.3

Given that  p-value  >  \alpha  we fail to reject the null hypothesis

   Hence we can conclude that there is no sufficient evidence to support the executive claim

The probability that the club chooses a girl and then a boy for the representative spots

Total = 15

Boys = 6

Girls = 9

Prob of 2 person, a girl and a boy

= (9*6)/(105)

= 54/105

= 0.514
