Answer:
AC=8
Step-by-step explanation:
We know that triangle ADC is a 30,60,90 triangle so the hypotenuse or AC is equal to 2 x the small side. In this case, it is 2 times AD or 2x4 which is equal to 8. Therefore, AC=8

Answer:
arc FG = 115°
arc EG = 165°
Step-by-step explanation:
The first step is to understand how these arcs are arranged on a circle. The next step is to realize the whole is the sum of the parts. Arcs have the same measure as their central angle. A circle totals 360°.
arc EF + arc FG = arc EFG . . . . parts of an arc add to give the whole arc
80° + arc FG = 195°
arc FG = 115° . . . . . . . . . subtract 80°
__
Similarly, parts of a circle add to give the whole circle.
arc EFG + arc EG = 360°
195° + arc EG = 360°
arc EG = 165° . . . . . . . . . subtract 195°

answer: 200
Step-by-step explanation:
Finding surface area for triangles is base × height ÷ 2 So 10 x 10 = 100 100 ÷ 2 = 50 sense all of these triangles are identical we just have to multiply 50 with the number of triangles so
50 × 4 = 200 So 200 is our answer. Hope this helps!

There are 750 people at a football game Out of this number 320 are students what percent of people at the football game are not students? Round to the nearest hundredth,if needed.
Answers
(430 are not students)
430/750= 0.5733333
To make it a percentage you move the decimal point 2 places to the left so it would be 57.3%
(I hope you understand I’m very bad at explaining)
The percent of people at the football game are not students will be 57.33%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The number of peoples in football game = 750
The number of students = 320
Now.
Find the percent of people at the football game are not students as;
Number of people are not students = 750 - 320
= 430
Thus, The percent of people at the football game are not students is;
Percent = 430 / 750 x 100
= 0.5733 x 100
= 57.33%
Hence, The percent of people at the football game are not students will be 57.33%.

If Henry decides to mow lawns then the opportunity cost would be - the chance to earn by working in a library
The correct answer is an option (B)
What is opportunity cost?"It is the value of what you lose when choosing between two or more options.""It is the value of the next best option."We know that,
the opportunity cost is the cost of the alternative that we waive when we make a certain decision, including the benefits that we could have obtained from having chosen the alternative option.It is referred to as "the value of the best option not selected".The opportunity cost is the values that are lost while choosing one alternative in place of others.This value may or may not be measured in money.It is the value of what you have to give up in order to choose something else.Henry wants to get a job this summer.
He can either mow lawns or work in the local library.
if he decides to mow lawns, he would lost the chance to earn by working in a library.
This means, the opportunity cost is - the chance to earn by working in a library
Therefore, if Henry decides to mow lawns then the opportunity cost would be - the chance to earn by working in a library

Mika is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124 families and finds that, on average, those families visit a farmers' market 4.2 times per month with a sample standard deviation of 1.3. If Mika wants to be 99% confident (z=2.58) using this sample, what should her margin of error be and what does it mean?
Answers
Answer:
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
Step-by-step explanation:
Margin of error
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Standard deviation of 1.3
This means that [tex]\sigma = 1.3[/tex]
She surveys 124 families
This means that [tex]n = 124[/tex]
Margin of error and meaning:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 2.58\frac{1.3}{\sqrt{124}}[/tex]
[tex]M = 0.3012[/tex]
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

How do you write an equation of a line that passes through (4,3) and has a slope of 2?
Answers
Answer:
y = 2x - 5
Step-by-step explanation:
y-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We know the slope is 2, so all that's left is to find the y-intercept. To do this, for every 1 we subtract from x in (4,3), we take away 2 from y because the slope is two. We keep doing this until x is zero. The remaining y-value is the y-intercept.
Answer:
[tex]y = 2x-5[/tex], see below.
Step-by-step explanation:
There is enough information to make a point slope equation that we can later convert into slope intercept.
Point slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex](x_1,y_1): \text{A point.} \\\\m - \text{Slope.}[/tex]
We are given the slope of 2 and the point (4,3).
Replace the variables with the given information.
[tex]y-y_1=m(x-x_1)\rightarrow y-3=2(x-4)[/tex]
With the equation we will now convert it into slope intercept form:
[tex]y-3=2(x-4)\\\\y-3=2x-8\\\\y-3+3=2x-8+3\\\\\boxed{y=2x-5}[/tex]
