Answer: 11
if u put 1 and 1 together
u get 11
Distributive Property: a ( b + c) = (a*b) + (a*c)
b) x(x + 9) = x*x + 9*x
= x² + 9x
c) x² - 18x
x² = x * x
18x = 18 *x
G C F = x
Greatest common factor in both the terms is 'x'.Take the common variable from both the terms.
x² - 18x = x*x - 18*x
= x (x - 18)
Standard form. Factored form
x² x*x
x² + 9x x(x +9)
x² - 18x x(x - 18)
-x² + 10x x(-x + 10) = x(10 -x)
-x² - 2.75x -x(x + 2.75)
Answer:
The value of "x" is 34 and the value of "y" is 17.
Step-by-step explanation:
"x" is shown as 34 and "y" is shown on the rectangular shape in the number form of 17. If your trying to find the area of the rectangle the area is 578.
Yep he said it best good job
Answer:
n=42 adult men
Step-by-step explanation:
-The minimum sample size to get a desired margin of error, E is calculated using the formula:
![n\geq( \frac{z\sigma}{E})^2](https://tex.z-dn.net/?f=n%5Cgeq%28%20%5Cfrac%7Bz%5Csigma%7D%7BE%7D%29%5E2)
-Given that
, we can substitute to solve for n in the above formula:
![n\geq (\frac{z\sigma}{E})^2\\\\\therefore n=(\frac{z_{\alpha/2}\sigma}{E})^2\\\\=(\frac{2.58\times7.5}{3})^2\\\\=41.6025\approx42](https://tex.z-dn.net/?f=n%5Cgeq%20%28%5Cfrac%7Bz%5Csigma%7D%7BE%7D%29%5E2%5C%5C%5C%5C%5Ctherefore%20n%3D%28%5Cfrac%7Bz_%7B%5Calpha%2F2%7D%5Csigma%7D%7BE%7D%29%5E2%5C%5C%5C%5C%3D%28%5Cfrac%7B2.58%5Ctimes7.5%7D%7B3%7D%29%5E2%5C%5C%5C%5C%3D41.6025%5Capprox42)
Hence, the desired minimum sample size, n is 42 adult men.
