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.

Voters in a community are considering a bond issue for a new school. The building plan and the projected increase in property taxes have been presented at several public meetings. With voting day just a few weeks away, Tasha is interested in determining whether the population of about 5,000 voters supports the bond issue. Describe in two to three sentences the best way for Tasha to sample the population so that she can conduct a survey.
Answer:
do you go gca too
Step-by-step explanation:
The best way to sample the population so that she can conduct a survey is to conduct a random sampling
How to determine the best way?From the question, we have the population to be:
Population = 5000
In order to conduct a survey, Tasha must carry out a random sampling by using the following steps
Set a small size of interval (say 5)Ask every other 5 (or the chosen size) people present at the meeting about the vote preference.The above is called a random sampling technique

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

If John solved the equation x? - 10x + 8 = 0 by completing the
square, one of the steps in his process would be
(1) (x-5)^2 = -8
(2) (x-5)^2 = 17
(3) (x+ 4)^2 = 10x
(4) (x + 4)^2 = 10x + 16
Answer:
[tex](x - 5)^{2} =17[/tex]
Step-by-step explanation:
[tex]x^{2} -10x = -8 \ add \ and \ subtract \ 25;\\x^2-10x+25-25= -8\\(x-5)^2 - 25 = -8\\(x-5)^2 = 17\\x-5=+\ \sqrt{17} \\\x_{1,} _{2} =5+\sqrt{17}[/tex]

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]

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.

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

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.
