Answer:
![g(15)=93.8\%](https://tex.z-dn.net/?f=g%2815%29%3D93.8%5C%25)
see the explanation
Step-by-step explanation:
Let
x ----> the number of years since 2008,
g(x) ----> the percent of people 25 years and older who have completed at least high school
we know that
![g(x)=0.008x^2+0.42x+87.5](https://tex.z-dn.net/?f=g%28x%29%3D0.008x%5E2%2B0.42x%2B87.5)
so
For x=15 years since 2008
substitute
![g(15)=0.008(15)^2+0.42(15)+87.5=93.8\%](https://tex.z-dn.net/?f=g%2815%29%3D0.008%2815%29%5E2%2B0.42%2815%29%2B87.5%3D93.8%5C%25)
That means
In the year 2023 (2008+15) the percent of people 25 and older completing at least high school will be 93.8%
Answer: C
Step-by-step explanation:
Since the heights of the men are assumed to be normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = heights of the men.
µ = mean height
σ = standard deviation
From the information given,
µ = 70.7 inches
σ = 2.1 inches
The probability that they have a mean height greater than 71.7 inches is expressed as
P(x > 71.7) = 1 - P(x ≤ 71.7)
For x = 71.7
Since n = 36, then
z = (71.7 - 70.7)/2.1/√36 = 2.86
Looking at the normal distribution table, the probability corresponding to the z score is 0.998
P(x > 71.7) = 1 - 0.998 = 0.002
Answer:
Step-by-step explanation:
the student buys a total of 8 magazines for $14.00
x+y = 8
x = 8-y
2x+1.6y = 14
2(8-y)+1.6y = 14
16-2y+1.6y = 14
16-0.4y = 14
0.4y =16-14 = 2
y = 2/0.4 = 5
x = 8-y = 3
