Answer: 24% of students
Step-by-step explanation:
6 students divided by 25 total students = 0.24. You would multiply 0.24 by 100 or move the decimal two places to the right to get the percentage. In this case, the percentage would be 24%. 24% of students do not play spring sports.
[tex]6/25 = 0.24 *100 = 24 percent[/tex]

1. The amount of time Mr. Smith spends exercising each day is
approximately normally distributed with a mean of 30 minutes and a
standard deviation of 10 minutes. On approximately what percent of the
days in a year does Mr. Smith exercise for between 10 minutes and 40
minutes?
Answer:boy
Step-by-step explanation:boy
Mr. Smith exercises for between 10 and 40 minutes on 77.45 percent of the days in a year.
Given that his exercising time follows a normal distribution with a mean of 30 minutes and a standard deviation of 10 minutes.
Here we have to find the percentage of days in a year that Mr. Smith exercises for between 10 and 40 minutes,
First, we need to standardize the values of 10 and 40 minutes using the formula,
⇒ z = (x - μ) / σ
where x is the value we want to standardize,
μ is the mean,
And σ is the standard deviation.
For x = 10:
⇒ z = (10 - 30) / 10
= -2
For x = 40:
⇒ z = (40 - 30) / 10
= 1
Now, we need to find the probability of Mr. Smith exercising between -2 and 1 standard deviations from the mean.
We can use a standard normal distribution table or a calculator to find this probability.
Using a standard normal distribution table,
we can find the probability of z being between -2 and 1 is about 0.7745. This means that on approximately 77.45% of the days in a year, Mr. Smith exercises for between 10 and 40 minutes.
Therefore,
Mr. Smith exercises for between 10 and 40 minutes on approximately 77.45% of the days in a year.

Find the equation of the exponential function represented by the table below:
Answer:
y = 0.2(0.5)^x
Step-by-step explanation:
Exponential function are of the form
y = ab^x
----------------------
To find "a" plug in x = 0 y = 0.2
0.2 = a(0.2)^0
0.2 = a
-------------------------
To find "b" plug in another point and a = 0.2
using x = 2, b = 0.05
0.05 = 0.2b^2
Divide both sides by 0.20
.25 = b^2
Take the square root of both sides
0.5 = b
-----------------------------
With a = 0.2 and b = 0.5 the equation becomes
y = 0.2(0.5)^x

Step-by-step explanation:
Angles 8x - 12 and 6x + 8 are adjacent angles.
Adjacent angles are equal.
8x - 12 = 6x + 8
8x - 6x = 8 + 12
2x = 20
x = 20 / 2
x = 10

100 students are interviewed to see which of biology, chemistry or physics they prefer.
39 of the students are girls. 21 of the girls like biology best.
16 of the boys prefer physics.
11 out of the 34 who prefer chemistry are girls.
What percentage of the students prefer biology?
Answer:
43% of the students prefer biology
Step-by-step explanation:
Among girls:
39 of the students are girls.
21 of the girls like biology best.
Boys:
100 - 39 = 61 are boys.
16 prefer physics
11 out of the 34 who prefer chemistry are girls, so 34 - 11 = 23 are boys.
61 - (16 + 23) = 22 prefer biology.
What percentage of the students prefer biology?
21 boys and 22 boys, that is, 43 students out of 100. So
43*100%/100 = 43%
43% of the students prefer biology

1. Christine picks three pumpkins. They weigh
6 14 pounds, 2 1/3 pounds, and 1 1/8 pounds.
What is the total weight of the pumpkins?
Answer: [tex]9\dfrac{17}{24}\ \text{Pounds}[/tex]
Step-by-step explanation:
Given
Christine Picks three Pumpkins which weighs
[tex]6\dfrac{1}{4}=\dfrac{6\times 4+1}{4}\ \text{Pounds}[/tex]
[tex]2\dfrac{1}{3}=\dfrac{2\times 3+1}{3}\ \text{Pounds}[/tex]
[tex]1\dfrac{1}{8}=\dfrac{8\times 1+1}{8}\ \text{Pounds}[/tex]
The total weight will be the addition of the weights of each pumpkin
[tex]\Rightarrow \dfrac{25}{4}+\dfrac{7}{3}+\dfrac{9}{8}\\\\\text{Take the LCM of the denominators which will be 24}\\\\\Rightarrow \dfrac{25\times 6}{24}+\dfrac{7\times 8}{24}+\dfrac{9\times 3}{24}\\\\\Rightarrow \dfrac{150+56+27}{24}\\\\\Rightarrow \dfrac{233}{24}\ \text{Pounds}\\\\\Rightarrow 9\dfrac{17}{24}\ \text{Pounds}[/tex]
Find the measure of arc BEF.
Given:
The diagram of a circle.
[tex]m\angle BPV=124^\circ ,m\angle VPE=30^\circ ,m\angle EPF=76^\circ, m\angle FPD=48^\circ[/tex].
To find:
The measure of arc BEF.
Solution:
The measure of central angle is equal to the measure of corresponding arc.
So, in the given figure,
[tex]n(arcBV)=124^\circ ,m(arcVE)=30^\circ ,m(arcEF)=76^\circ, m(arcFD)=48^\circ[/tex]
Now,
[tex]m(arcBEF)=m(arcBV)+m(arcVE)+m(arcEF)[/tex]
[tex]m(arcBEF)=124^\circ +30^\circ+76^\circ[/tex]
[tex]m(arcBEF)=230^\circ[/tex]
Therefore, the measure of arc BEF is 230 degrees.

Estimate 62% of 196.
A. 80
B. 100
C. 120
O D. 140
HURRY PLEASE
Answer:
The answer is C: 120
Step-by-step explanation:
Ok so to solve this, you need to know that when "of" is in an equation, it always means multiply.
So 62% of 196 = 62% * 196.
62% * 196 = 121.52
Then you need to round 121.52 to the nearest option, which is Option C: 120.

Here is the problem:)
Answer:
Yes, there are exactly 2 ways to solve this triangle.
Step-by-step explanation:
Well we know that to find out a trigonometric ratio we are given an angle and a side, and we have to solve for the other side. In this case only 2 of the legs are given, hypotenuse is neither given nor asked. So we have to use the ratio that doesn't have hypotenuse included. Tangent is the only such ration. Now we can use either Tan(51) or Tan(39) to solve for the "x".
These would be the functions to solve for x:
1.) Tan(51) = [tex]\frac{x}{10}[/tex]
2.) Tan (39) = [tex]\frac{10}{x}[/tex]
