Answer:
And we can find the probability with the complement rule and the normal standard distirbution and we got:
Step-by-step explanation:
Let X the random variable that represent the time spent reading of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And we can use the z score formula given by:
Using this formula we got:
And we can find the probability with the complement rule and the normal standard distirbution and we got:
20 degrees. i have a protractor, and its really helpful! you should use one.
Answer: I believe it’s C
Step-by-step explanation: I hope i’m right
Answer:
See below
Step-by-step explanation:
She combined 3x and - 9x incorrectly
she should have gotten - 6 x not - 12 x
The least common multiple of each pair of the polynomial (5y² - 80) and
(y + 4) is equal to 5(y-4)(y+4).
As given in the question,
Given pair of the polynomial is (5y² - 80) and (y + 4)
Simplify the given polynomial using (a² -b²) = (a-b)(a +b)
(5y² - 80) = 5(y² -16)
⇒(5y² - 80) = 5(y² - 4²)
⇒(5y² - 80) = 5(y -4)(y + 4)
And (y + 4) = (1) (y+4)
Least common multiple = 5(y-4)(y+ 4)
Therefore, the least common multiple of the given pair of the polynomial is 5(y -4)(y+ 4).
