Answer: -4(7g - 6h)(7g + 6h)
<u>Step-by-step explanation:</u>
Separate the 4 terms into two groups of 2 terms. Then factor out the GCF of each group. You should end up with a common factor in each group - that is one of the factors. The other factor is what you factored out from each term.
49g² - 36h² - 28g - 24h
(7g - 6h)(<u>7g + 6h</u>) -4(<u>7g + 6h</u>)
They both have a common factor of (7g + 6h)
The terms factored out are (7g - 6h) and -4
So, the factorization is: -4(7g - 6h)(7g + 6h)
Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16
i hope this work for you
Answer:
2.34
Step-by-step explanation:
Divide the total by the number of bags!
28.08/12=2.34
CHECK: 2.34*12=28.08
brainliest, please? ty! <3
The slope is the gradient
Gradient = rise/run
Gradient = -1/1
Gradient = -1
Slope = -1
