Answer:
B
Step-by-step explanation:
Here, we are to give the reason why we would reject the null hypothesis during the hypothesis testing.
In considering whether to accept the null hypothesis or reject the null hypothesis, we have to take into consideration two things.
The p-value and the alpha value. The p-value refers to the probability which is directly obtainable from the standard score which is referred to as the z-score while the alpha refers to the level of significance.
Now, when the p-value is less than alpha, we simply reject the null hypothesis and accept the alternative hypothesis. In a case however, we have the value of p greater than or equal to the significance level alpha, we simply accept the null hypothesis in this case.
The question asks for a rejection case and this can happen only when the p-value is less than the level of significance alpha
The answer is 9 I’m pretty positive
The expressions equivalent to 5+(-3)(6x-5) is -18 x +20 , Option A is the correct answer.
The complete question is
Which expressions are equivalent to 5+(−3)(6x−5)
Choose all answers that apply:
A : -18x+20
B: 3x-3
C: None of the above
<h3>What is an Expression ?</h3>
An expression is a mathematical statement that has variables , constants and mathematical operators all simultaneously.
The expression given is
5+(-3)(6x-5)
By Distributive Property
a(b+c) =ab+ac
5 + (-3*6x) -(-3*5)
5 - 18x +15
-18 x +20
Therefore Option A is the correct answer.
