Step-by-step explanation:
2.5 = 2 5/10 = 250%
40% = .40 = 40/100 = 4/10 =2/5
220% = 220/100 = 2 20/100 = 2 2/10 = 2 1/5
1/4 = 25/100 = 25%
4% = 4/100 = .04
Given:
μ = $3.26 million, averaged salary
σ = $1.2 million, standard deviation
n = 100, sample size.
Let x = random test value
We want to determine P(x>4).
Calculate z-score.
z = (x - μ)/ (σ/√n) = (4 - 3.26)/(1.2/10) = 6.1667
From standard tables,
P(z<6.1667) = 1
The area under the distribution curve = 1.
Therefore
P(z>6.1667) = 1 - P(z<=6.1667) = 1 - 1 = 0
Answer: The probability is 0.
You have

apples left.
You have 5 whole apples, you took one whole apple out, which equals 4 whole apples left. Then with the whole apple you took out, you ate

of it.
Jack ate
of an apple in 5 apples. If you say that Jack ate

of 3 apples, then he ate

apples. So there isn't any difference when he ate

of an apple.

Step-by-step explanation:
x-7=-5x-1
x-(-5x)-7=-1
x+5x-7=-1
6x-7=-1
6x=-1+7
6x=6
x=6/6
x=1
