Answer:
29/7
Step-by-step explanation:
10-5x=3(x-4)-(x+7)
10-5x=3x-12-x-7
10-5x=3x-x-12-7
10-5x=2x-19
10-5x-2x=-19
10-7x=-19
7x=10-(-19)
7x=10+19
7x=29
x=29/7
21

In stratified sampling, a sample is drawn from each strata (using a random sampling method like simple random sampling or systematic sampling). In cluster sampling, the sampling unit is the whole cluster; Instead of sampling individuals from within each group, a researcher will study whole clusters.
Answer:
<h2>(g+ h) (-3) = 4</h2>
Step-by-step explanation:
g(x) = 8x - 3
h(x) = 3x² - 2x - 2
To find (g+ h) (-3) we must first find
(g+ h) (x)
To find (g+ h) (x) add g(x) to h(x)
That's
(g+ h) (x) = 8x - 3 + 3x² - 2x - 2
(g+ h) (x) = 3x² - 2x + 8x - 3 - 2
(g+ h) (x) = 3x² + 6x - 5
To find (g+ h) (-3) substitute the value of x that's - 3 into (g+ h) (x) that's for every x in (g+ h) (x) replace it with - 3
We have
(g+ h) (-3) = 3(-3)² + 6(-3) - 5
= 3(9) - 18 - 5
= 27 - 18 - 5
We have the final answer as
<h3>(g+ h) (-3) = 4</h3>
Hope this helps you
