True [87]3 years ago
5 0

Answer:

Step-by-step explanation:

12(4x - 5) + \frac{5}{2}=10

Multiply the whole equation by 2

2*12(4x -5) + \frac{5}{2}*2=10*2\\\\24(4x-5) + 2 = 20\\

24*4x - 5*24 + 2 = 20

96x - 120 + 2 = 20

 96x - 118 = 20

Add 118 to both sides

       96x = 20 +118

       96x = 138

Divide both sides by 96

x = 138/96  = 23/16

x = 1 \frac{7}{16}

Which number is in the solution set of this equation? 7x − 9 = 40
skad [1K]

Answer: the answer is 7

Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40

7(7)=49 next 49-9= 40

it checks out, so x= 7

inysia [295]

Answer:

<u>B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed. </u>

Step-by-step explanation:

We make this conclusion based on these reasons:

  1. We are told that the "null hypothesis was rejected" after the <em>"manager feels that the pressure variability has changed.,</em> meaning the <u>null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.</u>
  2. <em>"changes in the manufacturing​ process"</em> form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.

It is based on the above reasons that the null hypothesis was rejected.
