Answer: 0.16
Step-by-step explanation:
Let X be a random variable that represents the heights of women at a large university are approximately bell-shaped, with a mean of 66 inches and standard deviation of 3 inches.
According to the Empirical Rule, for bell-shaped distributions, about 68% of the values fall within 1 standard deviation of the mean.
About 68% woman have height between ( 66-3) inches and (66+3) inches.
i.e. About 68% woman have height between 63 inches and 69 inches.
The percentage of woman have height either less than 69 inches or greater than 69 inches =100% - 68%= 32% [both share equal area on curve.]
The percentage of woman have height is 69 inches or taller = 32%÷2
= 16%
Hence, the probability that a randomly selected woman from this university is 69 inches or taller =16%=0.16
a 175,000 loan compounded monthly at 3.2% for 19 years. how much intrest was earned
Answer:
Interest earned = $146,196.75
Step-by-step explanation:
A = $175,000
r = 3.2% = 0.032
n = 19
m = 12
FV = A*(1+i/m)^nm
FV = 175,000*(1+0.032/12)^19*12
FV = 175,000*(1+0.002667)^228
FV = 175,000*(1.002667)^228
FV = 175,000*1.83541
FV = $321196.75
Interest earned = $321,196.75 - $175,000
Interest earned = $146,196.75

What is the question?
A goat is tethered to a rope that is 3.65 meters long. What is the maximum area of grass that the goat can graze on?
Answer:
3.65 meters
Step-by-step explanation:
If the rope is 3.65 meters long, then the goat can only go as far as the rope is long. That's unless the goat eats the rope.
The maximum area that a goat can graze on will be the area of a circle where the center of the circle will be one end of the rope as shown in the attached diagram.
What is the area of a circle?The area of a circle with radius r is πr².
Radius of the circle= length of the rope = 3.65m
So, area of the circle = [tex]\pi r^{2}[/tex]
Area of the circle = [tex]\pi 3.65^{2}[/tex]
Area of the circle = 41.85m².
Therefore, the maximum area of grass that the goat can graze on is 41.85 m²

According to data obtained from the National Weather Service 187 of the 368 people killed by lightning were men. Assume that this trend holds for the future. What is the probability that a person killed by lightning is a woman
Answer:
0.4919
Step-by-step explanation:
From the given data:
187 of the 368 people killed by lightning were men.
i.e
Number of men = 187
Total number of people killed = 368
The objective is to determine the probability that the person killed by lightning is a woman.
The number of women = 368 - 187
The number of women = 181
The probability that the person killed by lightning is a woman = 181/368
= 0.4919

what are the property for each equation
Answer:
associative, distributive, commutative
Step-by-step explanation:
Commutative is something just flipped around so the 3rd equation would be commutative. Associative is something with the same numbers but asked in a different way so 1st would be associative. Distributive is breaking the equation down and apart to make it easier to complete so the 2nd would be distributive.

Jonny is buying a new pair of shoes. If the shoes are normally $25.00 and are on sale for 20% off, how much will he pay for the shoes before tax?
Answer:
$20
Step-by-step explanation:
First, we need to find 20% of $25. You can do this by multiplying $25 by 0.2
After multiplying , you get $5. So 20% of 25 is 5.
Now, we subtract because the shoes are 20% off
25 - 5 = $20
I hope this helped, please mark Brainliest, thank you!
Answer:
If Jonny is buying a new pair of shoes for that were $25.00 before the shoes went on sale the shoes are now 12.50 ct

One number is selected from the set {1, 2, 3, 4, 5, 6, 7, 8, 9}. Find the probability the selected number is less than 7, given that it is less than 8.
Give your answer as a decimal rounded to 4 decimal places.
====================================================
Explanation:
We're told that "given that it is less than 8", so we only focus on these values {1,2,3,4,5,6,7}. There are B = 7 items in this set.
Of those, the set {1,2,3,4,5,6} are less than 7. There are A = 6 items in this set.
The probability we're after is A/B = 6/7 = 0.8571
Answer:
I just got this question in my book, and i already solved it. so just saying that i now the answer, it is 0.8571

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 minutes. Find the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes.
Answer: 0.75
Step-by-step explanation:
Given : Interval for uniform distribution : [0 minute, 5 minutes]
The probability density function will be :-
f(x) = 1/5-0 = 1/5 = 0.2, 0<x<5
The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-
Hence, the probability that a randomly selected passenger has a waiting time greater than 1.25 minutes = 0.75

Find the directional derivative of the function f(x,y)=2cos(y)exf(x,y)=2cos(y)ex at the point (0,π6)(0,π6) in the direction of the vector v=⟨−8,6⟩v=⟨−8,6⟩.
Answer:
[tex]D_u f(0,\pi/6)=\frac{4\sqrt{3}-3}{5}[/tex]
Step-by-step explanation:
We are given that
[tex]f(x,y)=2cos(y)e^{x}[/tex]
Point=([tex]0,\pi/6[/tex])
Vector v=<-8,6>
We have to find the directional derivative of the function.
[tex]f_x(x,y)=2cos(y)e^{x}[/tex]
[tex]f_x(0,\pi/6)=\sqrt{3}[/tex]
[tex]f_y(x,y)=-2sin(y)e^{x}[/tex]
[tex]f_y(0,\pi/6)=-1[/tex]
[tex]|v|=\sqrt{(-8)^2+6^2}=\sqrt{100}=10[/tex]
[tex]\hat{u}=\frac{v}{|v|}=\frac{-8i+6j}{10}=\frac{1}{10}(-8i+6j)[/tex]
[tex]\nabla f(0,\pi/6)=<f_x(0,\pi/6),f_y(0,\pi/6)>=<\sqrt{3},-1>[/tex]
Now, the directional derivative in the direction of v at point (0,[tex]\pi/6[/tex]) is given by
[tex]D_u f(0,\pi/6)=\nabla f(0,\pi/6)\cdot \hat{u}[/tex]
By using the formula
[tex]D_u f(x,y)=\nabla f(x,y)\cdot \hat{u}[/tex]
[tex]D_u f(0,\pi/6)=<\sqrt{3},-1>\cdot <-\frac{8}{10},\frac{6}{10}>[/tex]
[tex]D_u f(0,\pi/6)=-\frac{4\sqrt{3}}{5}-\frac{3}{5}=-\frac{1}{5}(4\sqrt{3}+3)[/tex]
