Answer:
a) P [ x ≤ 7000] is 0.55
b) P [ x > 5000 ] = 0.95
c) P [ 5000 < x ≤ 7000 ] = 0,5
Step-by-step explanation:
a) P [ x > 7000 ] = 0.45 straightforward P [ x ≤ 7000] is 0.55
The whole spectrum of probabilities is 1 which in this particular case is divided in two parts having 7000 as a limit, then we subtact 1 - 0.45
b) P [ x ≤ 5000] = 0.05 again we get P [ x > 5000] taking 1-0.05 to get
P [ x > 5000 ] = 0.95
c) P [ 5000 < x ≤ 7000 ]
Under Normal curve distribution the probability of x ≤ 7000 includes values smallers ( to the left of 5000) so we subtract from 0.55 - 0.05 = 0.50
c) P [ 5000 < x ≤ 7000 ] = 0,5

A vertical stretch of 3, left 9 units, and up 6 units
Answer:
0.875
Step-by-step explanation:
1/2 was broccoli and 1/2 was mushroom...
he ate 2/3 of the broccoli part......2/3 of 1/2 = 2/3 * 1/2 = 2/6 = 1/3
he ate 1/4 of the mushroom part....1/4 of 1/2 = 1/4 * 1/2 = 1/8
so he ate 1/3 + 1/8 = 8/24 + 3/24 = 11/24 <==
