Answer:
7788 observations are expected to be below a value of 242.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 188, standard deviation = 18
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
Percentage of observations below 242:
242 = 188 + 3*18
So 242 is three standard deviations above the mean
Of the measures below the mean, all are below 242.
Of the measures above the mean, 99.7% are between the mean of 188 and three standard deviations above the mean(242). So the percentage is:
[tex}P = 0.5 + 0.997*0.5 = 0.9985[/tex]
Number of observations below 242:
99.85% of 7800 observations
0.9985*7800 = 7788
7788 observations are expected to be below a value of 242.

If F(x) = 9x, which of the following is the inverse of Fx)?
Answer:
F⁻¹(x) = x/9
Step-by-step explanation:
To find the inverse of a function, you want to switch x and y in the equation and solve for y.
F(x) = 9x
x = 9F(x)
x/9 = F⁻¹(x)
Therefore, the inverse is F⁻¹(x) = x/9.

C. 2 hours
D. They will never meet.
Answer:
C. 2 hours

you have 7/8 of a pizza left over form a party. you would like to give each friend 1/4 of the left over pizza. how many friends can you give 1/4 of the pizza to
A. 7/32
b 1
c 3
d 3 1/2
Answer: C
Step-by-step explanation:
Answer and Step-by-step explanation:
The answer is C.
[tex]\frac{1}{4} = \frac{2}{8}\\\\[/tex]
Each friend will be receiving [tex]\frac{2}{8}[/tex] of a pizza.
[tex]\frac{7}{8} - \frac{2}{8} - \frac{2}{8} - \frac{2}{8} = \frac{1}{8}[/tex]
You can't give someone [tex]\frac{1}{8}[/tex] of a pizza, and you can't have half of a friend, so that one remains uneaten. This means that you give pizza to 3 friends.
