Answer:
79 degrees i think
Step-by-step explanation:
Lines that are horizontal and straight are always 180 degrees so i just subtracted 180 degrees from 101 and i got 79 degrees
Answer:
x = 79
Step-by-step explanation:
A straghit line is equal to 180 degrees.
If 101 of it is taken, you have to find out what the other side is equal to.
The equation would look like: 101 + x = 180 or 180 - 101 = x
I hope you understand now! :D

Section 3 - Topic 1 What is a Function? 1. A group of students were discussing whether the relationship on the graph is o function Ed: The relotionship is not a function because if I craw a horizontal line at y= 2, the horizon al line crosses the graph ot two points. Debra: The relationship is a function because it is a graph of two different Alejandro: The relationship is not a function because x = 1 has two different y-values. Antoine: The relationship is a function because I can write an equation for diline. Which students are not correct and whot is the flow in their argument:
9514 1404 393
Answer:
Not correct: Ed, Debra, Antoine
Step-by-step explanation:
Ed is incorrect because he is using a horizontal line test instead of the appropriate vertical line test.
Debra is incorrect because the fact it is two different lines is irrelevant. A piecewise linear function may be two or more different lines.
Antoine is incorrect because the existence of an equation for the curve has nothing to do with whether or not it is a function. (Here, Antoine would need two equations with overlapping domains. The overlap of the domains is what tells you it is not a function.)
__
Alejandro is correct. The relation fails the vertical line test

Find the radius c=63 ft
Complete the solution of the equation. Find
the value of y when x equals 12.
x + 3y = 21
Answer:
y=3
Step-by-step explanation:
12+3y=21
-12 -21 subtract 12 from both sides
------------------
3y=9
divide 3 from y and 9, so you can get y by itself
3y/3= y 9/3= 3
so y is equal to 3

A frequency distribution for the response time for EMTs after a 911 call is shown below.
Response Time for EMTS
Frequency
Response Time
(in minutes)
7-7.9
19
8-8.9
23
9-9.9
38
47
10 - 10.9
11 - 11.9
12 - 12.9

29
13-13.9
21
Step 2 of 2: Calculate the population variance for the response time. Round any intermediate calculations, if needed, to no less than four decimal places, and round
your final answer to two decimal places.
Answer: σ² = 2.90
Step-by-step explanation: For a frequency table, population variance is calculated by:
[tex]\sigma^{2}=\frac{\Sigma f(x-\mu)^{2}}{\Sigma f}[/tex]
where
f is frequency
μ is expected value or mean of the distribution
In this case, mean of the distribution for a grouped frequency table is calculated by:
[tex]\mu=\Sigma x.f(x)[/tex]
where
x is (as the data is grouped) the mid value of the response time
So, the table is
x | f
6.45 | 18
7.45 | 21
8.45 | 34
9.45 | 46
10.45 | 46
11.45 | 25
12.45 | 21
And mean will be:
[tex]\mu=6.45(18)+7.45(21)+8.45(34)+9.45(46)+10.45(46)+11.45(25)+12.45(21)[/tex]
μ = 9.5874
To calculate the variance, the formula above is transformed into
[tex]\sigma^{2}=\frac{\Sigma f.x^{2}-\frac{(\Sigma f.x)^{2}}{\Sigma f} }{\Sigma f}[/tex]
So, to facilitate the calculations, divide each term in a table:
f | x | f.x | f.x²
18 | 6.45 | 116.1 | 748.845
21 | 7.45 | 156.45 | 1165.5525
34 | 8.45 | 287.3 | 2427.685
46 | 9.45 | 434.7 | 4107.915
46 | 10.45 | 480.7 | 5023.315
25 | 11.45 | 286.25 | 3277.5625
21 | 12.45 | 261.45 | 3255.0525
∑ 211 | | 2022.95 | 20005.9275
Population variance will be:
[tex]\frac{(\Sigma f.x)^{2}}{\Sigma f} =[/tex] [tex]\frac{(2022.95)^{2}}{211}[/tex] = 19394.9133
[tex]\sigma^{2}=\frac{\Sigma f.x^{2}-\frac{(\Sigma f.x)^{2}}{\Sigma f} }{\Sigma f}[/tex]
[tex]\sigma^{2}=\frac{20005.9275-19394.9133}{211}[/tex]
σ² = 2.90
The population variance for the response time for EMTs is 2.90.

It takes 30 mins to shape 10 pots, and heating all 10 pots takes 10 mins. Add 30 and 10 minutes to get: 40 minutes.
Answer:
3p + 10; 40 minutes
Step-by-step explanation:
It takes 3 minutes to shape one pot.
It takes 3p minutes to shape p pots.
A batch of pots has p pots and takes 10 minutes in the kiln.
The total time it takes to make 1 batch is the time to shape the pots, 3p, plus the time in the kiln, 10 minutes.
The expression is
3p + 10
For a batch of 10 pots, p = 10.
3p + 10 = 3(10) + 10 = 30 + 10 = 40
Answer: 3p + 10; 40 minutes

1/3+4/9= please help
Answer:
7/9
Step-by-step explanation:
Answer:
It equals 7/9
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(1/3×3/3)+(4/9×1/1)=?
Complete the multiplication and the equation becomes
3/9+4/9=?
The two fractions now have like denominators so you can add the numerators.
Then:
3+4
------- =7/9
9
This fraction cannot be reduced.
Therefore:
1/3+4/9=7/9

The length of a rectangle is 5 inches more than the width. The perimeter is 46 inches. Find the length and the width.
The length is inches___ and the width is_____ inches.
Answer:
width: 9 inches
length: 14 inches
Step-by-step explanation:
width: x
length: x + 5
perimeter = 2L + 2W
46 = 2(x + 5) + 2x
46 = 2x + 10 + 2x
46 = 4x + 10
36 = 4x
x = 9
width: 9
length: 9 + 5 = 14
