Given a mean of 80 and a standard deviation of 3, label the normal curve below.
Answers
Answer:
The points from the left;
71, 74 , 77, 80, 83, 86 , 89
Step-by-step explanation:
Here, we want to label the normal curve given the mean and the standard deviation
From what we have, the central part is the mean while the other parts are deviations from the mean
We will label the graph starting from the left to the right
1 is 3 SD from the mean (negatively)
That will be 80-3(3) = 80-9 = 71
2 is 2 SD away
That will be;
80 -2(3) = 80-6 = 74
The 3rd part is 1 SD away
That will be 80-3 = 77
The midpoint is for the mean which is 80
The point after this will be;
80 + 3 = 83
The point after this will be;
83 + 3 = 86
Next is
86 + 3 = 89

The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5

7. Sound travels through air at 330 meters per second. How long will it take a bat's cry to reach its prey and echo back if the prey is 1 meter away? Round to the nearest thousandth of a second.
show your work pls and this is my 3rd time asking LOL
Answers
It takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back
How to determine how long will it take a bat's cry to reach its prey and echo back?The given parameters are
Speed = 330 meters per second
Distance = 1 meters
The time taken to get to the prey is calculated as
Speed =Distance/Time
Substitute the known values in the above equation
So, we have
330 = 1/Time
Cross multiply the factors of the equation
So, we have
Time * 330 = 1
Divide both sides of the equation by 330
So, we have
Time 1 = 1/330
Similarly, the time taken to get from the prey is calculated as
Speed =Distance/Time
Substitute the known values in the above equation
So, we have
330 = 1/Time
Cross multiply the factors of the equation
So, we have
Time * 330 = 1
Divide both sides of the equation by 330
So, we have
Time 2 = 1/330
The time it takes a bat's cry to reach its prey and echo back is
Time = Time 1 + Time 2
So, we have
Time = 1/330 + 1/330
Evaluate the sum
So, we have
Time = 2/330
Simplify the quotient
So, we have
Time = 1/165
Hence, it takes the sound of a bat's cry 1/165 seconds to reach its prey and echo back

Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought lunch from home. Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.
If each spinner is divided into 15 congruent sectors, how does the spinner representing Mr. Skinner’s class differ from the spinner representing Ms. Cho’s class?
One more sector of the Skinner-class spinner will represent bringing lunch from home.
One fewer sector of the Skinner-class spinner will represent bringing lunch from home.
Two more sectors of the Skinner-class spinner will represent bringing lunch from home.
Two fewer sectors of the Skinner-class spinner will represent bringing lunch from home.

The Video Club charges a $100 membership fee and then charges $5 per movie. The Movie Market has a $25 membership fee and then charges $10 per movie. When will both clubs have the same cost? What is the cost?
Answers
Answer:
At 15 movies, both will cost $175
Step-by-step explanation:
Set it up algebraicly. Let x be the number of movies
100 + 5x = 25 + 10x
75 + 5x = 10x
75 = 5x
x = 15
Lets substitute x into one equation
100 + 5(15)
100+75
175
