We want the equation in the form y = mx + b.
We are given that m = -7.
The y-intercept (our b) is 8.
Here it is:
y = -7x + 8
Answer:
-8 and -2
Step-by-step explanation:
f(x) basically means y and at the y value 0 the x values are -8 and -2 (also known as the roots of the function)
Answer:
If a 1% level of significance is used to test a null hypothesis, there is a probability of ____ less than 1%______ of rejecting the null hypothesis when it is true
Step-by-step explanation:
Given that a hypothesis testing is done.
Level of significance used is 1%
i.e. alpha = 1%
When we do hypothesis test, we find out test statistic Z or t suitable for the test and find p value
If p value is < 1% we reject null hypothesis otherwise we accept null hypothesis.
So p value can be atmost 1% only for accepting null hypothesis.
So the answer is 1%
If a 1% level of significance is used to test a null hypothesis, there is a probability of ____less than 1%______ of rejecting the null hypothesis when it is true.
Distribute the 5 to both b and 3
5(b) = 5b
5(3) = 15
5b + 15 = b + 39
move all the b's to one side and the numbers to the other (do the opposite sign)
5b (-b) + 15 (-15) = b (-b) + 39 (-15)
5b (-b) = 39 (-15)
4b = 24
divide 4 from both sides
4b/4 = 24/4
b = 24/4
b = 6
6 is b, and is your answer
hope this helps
The solution is 6
9x6+3=57
