25% of 30 = 7.5
Hope this helps idk if it does tho
Answer:
84
Step-by-step explanation:
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.
Then it is $19:99 per chesse piece
For box of 100 gloves, each glove = 44.95/100 =
$0.4495
For box of 50 gloves, each glove = 23.50/50 = $0.47
<span>
Thus the box of 100
gloves is good to buy than the box of 50 gloves.</span>
