Answer: 0.80
<u>Step-by-step explanation:</u>
P (2 ≤ x ≤ 4) is: P(X = 2) + P(X = 3) + P(X = 4)
= 0.36 + 0.12 + 0.32
= 0.48 + 0.32
= 0.80
It can also be calculated as: 1 - P(X = 1)
= 1 - 0.20
= 0.80
Answer:
3(2x + 3y)
Step-by-step explanation:
Here, we want to divide
The inner term of the first part can be splitted by the use of the difference of two squares
That is;
given two perfect squares, separated by negative; we can write the factors as;
a^2-b^2 = (a-b)(a + b)
Thus;
4x^2 - 9y^2 = (2x-3y)(2x + 3y)
matching term for term;
6x/2x will give 3
while (2x-3y)(2x + 3y)/(2x-3y) = 2x + 3y
So we have the results of the division as;
3(2x + 3y)
