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

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 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
info: use CORRESPONDING ABC AND DEF .

Step 1: Define
We are given a right triangle. We can use trig to find the missing length.
Step 2: Identify Variables
Angle = 31°
Opposite = 19
Hypotenuse = x
Step 3: Solve for x
Substitute: sin31° = 19/xMultiply x on both sides: xsin31° = 19Isolate x: x = 19/sin31°Evaluate: x = 36.8905Round: x ≈ 36.97. Sound travels through air at 330 meters per second.

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
