asambeis [7]2 years ago

Answer:

Step-by-step explanation:

15a²bc = 3·5·a²·b·c

20ab²c = 2²·5·a·b²·c

25bc³ = 5²·b·c³

greatest common factor: 5bc

(-15a²bc + 20ab²c - 25bc³)÷(5bc) = -3a² + 4ab - 5c²

-15a²bc + 20ab²c - 25bc³ = (-3a² + 4ab - 5c²)(5bc)

VikaD [51]

Given :

Susan wanted to share her 37 seashells with her two younger brothers.

To Find :

If she divided her seashells between the three of them, how many would each person get.

Solution :

Let, each person will get x seashells.

So,

x = \dfrac{\text{Total number of seashells}}{\text{Number of persons}}\\\\x = \dfrac{37}{3}\\\\x = 12.333

But as we know seashells cannot be in decimal.

Therefore, each person will get exactly 12 shells.

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
