Which value of x makes the following equation true? <br> 6(x - 1) = -2x + 50
lakkis [162]

Answer:

x=7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(x−1)=−2x+50

(6)(x)+(6)(−1)=−2x+50(Distribute)

6x+−6=−2x+50

6x−6=−2x+50

Step 2: Add 2x to both sides.

6x−6+2x=−2x+50+2x

8x−6=50

Step 3: Add 6 to both sides.

8x−6+6=50+6

8x=56

Step 4: Divide both sides by 8.

8x /8 = 56 /8

x=7

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
