Answer: the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
Step-by-step explanation:
Given that;
p = 10% = 0.1
so let q = 1 - p = 1 - 0.1 = 0.9
n = 818
μ = np = 818 × 0.1 = 81.8
α = √(npq) = √( 818 × 0.1 × 0.9 ) = √73.62 = 8.58
Now to find P( x < 100)
we say;
Z = (X-μ / α) = ((100-81.8) / 8.58) = 18.2 / 8.58 = 2.12
P(x<100) = P(z < 2.12)
from z-score table
P(z < 2.12) = 0.9830
Therefore the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
Answer:
w = 62m
Step-by-step explanation:
We need to make an expression for the numbers of words (w) John types in m minutes.
We know he types 62 words in 1 minute, so 62 is the coefficient of m.
The dependent variable here is w, so that should on the left of the equal sign.
m, on the other hand, is independent, so that's on the right of the equal sign.
So, the expression is w = 62m.
Tom is spending more on tax totaling 23.54
while his cousin is only spending 18.72
How to get tax with percent take base price ex:22+ 7%
transform percent into a decimal : .07
now multiply the decimal times base price : 22x0.07
tax is a $1.54 now add that to your base price 22
and you get your total $23.54
F(4)= -64-3=-69 g(5)= -15-3=-18
