Answer:
Quotient = a²+ 4a- 2
Step-by-step explanation:
(8a3+31a2-20a-5)/(8a-1)
=
<u> a² +4a-2 ⇒ quotient</u>
(8a-1)√(8a3+31a2-20a-5)
8a²- a² ⇒ Multiplying (8a-1) by a²
<u> - + </u> ⇒ Changing signs
32a²- 20a- 5
32a²- 4a ⇒ Multiplying (8a-1) by 4a
<u> - + </u> ⇒Changing signs
-16a -5
- 16a +2 ⇒ Multiplying (8a-1) by -2
<u> + - ⇒</u> Changing signs
-7 ⇒ Remainder
We follow the steps of simple division to get the quotient which is a²+ 4a- 2
We multiply (8a-1) by factors such as a², +4a and -2 to get the same terms as given in the dividend.
Answer:
Step-by-step explanation:
b = pints of blueberries
c = pints of cherry tomatoes
3b + 2c = 28
2b = c
First, substitute 2b into the c of the first equation.
3b + 2(2b) = 28
3b + 4b = 28
7b = 28
b = 4
Then, substitute 4 into the b of the second equation.
2(4) = c
c = 8
Then, substitute both values into the first equation to check.
3(4) + 2(8) = 28
12 + 16 = 28
Answer:
Slope intercept form is y = mx + b
m is slope
b is y intercept
y = -4/5x + -9
I only know that first one sry
Step-by-step explanation:
<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
