Step-by-step explanation:
The equation is a reduction
it’s scale factor is 1/ 2
an algebraic representation for the dilation is written as (x, y) -> (kx, ky), with k being the variable for the scale factor
(2, 6) -> (1/ 2 • 2, 1/ 2 • 6)
Answer:
Step-by-step explanation:
1)
2(x – 4) + 32
Multiply it out.
2 * x - 2 * 4 + 32
2x - 8 + 32
2x + 24
2)
9x + 4(x + 2) – 5
Multiply it out
9x + 4 * x + 4 * 2 - 5
9x + 4x + 8 - 5
13x + 3
If U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g), find A-B and A nB.
Assoli18 [71]
<em>here</em><em>,</em>
U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g),
now,
A-B = {a,b}
A n B = { c,d,e}
We will see that the probability of x taking on a value between 75 to 90 is P = 0.5
<h3>
How to get the probability?</h3>
We know that x is a continuous random variable uniformly distributed between 65 and 85.
This means that the probability that x value y in the range is such that:
1 = P(y)*(85 - 65) = P(y)*20
1/20 = P(y).
Now, the probability of x taking a value between 75 and 85 is:
P(75 to 85) = (1/20)*(85 - 75) = 10/20 = 0.5
And the probability between 85 and 90 is zero (because the maximum value that x can take is 85, so this part does not affect).
Then we conclude that the probability of x taking a value between 75 to 90 is:
P(75 to 90) = P(75 to 85) + P(85 to 90) = 0.5 + 0 = 0.5
