Answer:

-4

Step-by-step explanation:

-129 = 6(7 + 7x) - 3

Distribute the 6 into the parentheses.

-129 = 42 + 42x - 3

Add like terms.

-129 = 39 +42x

Subtract 39 from both sides.

-168 = 42x

Divide 42 from both sides.

-4 = x

Answer:

x = -4

Step-by-step explanation:

6(7 + 7x) - 3 = -129

=>42 + 42x - 3 = -129

=>39 + 42x = -129

=>42x = -129 - 39

=>42x = -168

=>x = -168/42

=>x = -4

If the level of significance (alpha) is 0.05, it means that the probability of rejecting the null hypothesis, when it is false,

Kaylis [27]

Answer: The probability of rejecting the null hypothesis, when it is true, is 5%.

Step-by-step explanation:

We know that the level of significance ( denoted as $\alpha$ ) is generally the probability of rejecting the null hypothesis when it is true.

Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.

i.e. The probability of rejecting the null hypothesis when it is true= 0.05

In percent : $0.05=5\%$

Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.
