Calculate like terms:
7x-8=8x
7x-8x=8
-x=8
-x/-1=8/-1
x=-8
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.
Answer:
<h2>
1.33</h2>
Step-by-step explanation:
3/4 = 0.75 pound
1 : 0.75 = x : 1
x = 1 * 1 : 0.75
x = 1.33
--------------check
1 : 0.75 = 1.33 : 1
1.33 = 1.33
the answer is good
