Answer:
i) 0.872
ii) 0.300
iii) 0.76
iv) 0.704
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $261.50 per month
Standard Deviation, σ = $16.25
We are given that the distribution of monthly food cost for a 14- to 18-year-old male is a bell shaped distribution that is a normal distribution.
Formula:
a) P(Less than $280)
Calculation the value from standard normal z table, we have,
b) P(More than $270)
P(x > 270)
Calculation the value from standard normal z table, we have,
c) P(More than $250)
P(x > 250)
Calculation the value from standard normal z table, we have,
d) P(Between $240 and $275)
e) Thus, 0.704 is the probability that the monthly food cost for a randomly selected 14- to 18-year-old male is between $240 and $275.
Answer:
The last one
Step-by-step explanation:
when you are dividing an equation with exponents, you subtract the exponents from each other.
For example, in your problem you have d^4 and d^2 (notice that they have the same base) you subtract the exponents to get d^2
** even if the bases are numbers, you DONT touch the base, just the exponents ( ex.: 5^4 ÷ 5^3 = 5^1)
Do this w/ the rest of the exponents.
d^4 ÷ d^2 = d^2
e^3÷e^2= e
f^5÷f= f^4
** although f looks like it doesn't have an exponent, it has an invisible one
And w/ the power of deduction, you should get -2/3 d^2ef^4
The x variable is the first number in the parentheses. (X,Y) so you would go to -2 on the X axis(the horizontal line) and then go up 5 which is the y axis
