Answer:
A
Step-by-step explanation:
Given
p² + 2p - 8 = 0 ← in standard form
with a = 1, b = 2, c = - 8
Using the quadratic formula to solve for p
p = ( - 2 ± 
/ 2
= ( - 2 ± 
/ 2
= ( - 2 ± 
) / 2
p = 
= 
= - 4
p = 
= 
= 2
Answer:
1. z = 5, 2. w = 9
Step-by-step explanation:
1. 5z - 4 = 21
5z = 21 + 4
5z = 25
z = 25/5
z = 5
2. w/9 + 2 = 3
w/9 = 3 - 2
w/9 = 1
w = 1 x 9
w = 9
I hope this helps :)
12 because there is 8 ounces in a cup so 3*824 divided by 2 is 12
Answer:
1. b. 14.6 ± 7.38
2. b. 3.43
3. b. 0.01 < P-value < 0.05
4. b. There is sufficient evidence to reject the null hypothesis.
Step-by-step explanation:
The hypothesis test is used to test the null hypothesis against the alternative hypothesis. The p value of the test determines whether to accept or reject the null hypothesis. In the given scenario the p value is less than 0.05 so there is sufficient evidence against the null hypothesis in favor of alternative hypothesis.
To answer the calculation 1/2 + 3/4, you need to do the following:
1/2 + 3/4 =
2/4 + 3/4 =
(2 + 3) / 4 =
5/4 This can be also written as
.
