Answer:
6xy(15xy−1)
Step-by-step explanation:
The value of x from the expression is 2
<h3>Expression and equation </h3>
Given the expression
2x = 74/2 - 37
We are to calculate the value of x from the expression
2x = 37 - 37
Since 37 - 37 = 0
2x = 0
Divide both sides by 2:
2x/2 = 0/2
x = 0
Hence the value of x from the expression is 2

The answer is definitely false
F = kq2 / r2
q = ne
F = k(ne)2 / r2
n = âš(r2F / ke2) = (r/e) âš(F/k)
k = 9 x 109 Nm2/C2
e = 1.6 x 10-19 C
n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
Answer:
Step-by-step explanation:
The null hypothesis is usually the default statement while the alternative hypothesis is its opposite and usually tested against the null hypothesis.
In this case study, the null hypothesis is u = 21%/0.21, the percentage is not different among residents in Sonoma County and is equal to 0.21.
While the alternative hypothesis is u =/ 0.21, the percentage is different among residents in Sonoma County; not equal to 0.21
