What is the value of z?
Answers
explanation: in order to find z you need to add all of the angles given together, and all triangles equal to 180 . so 8z+12^+19z+15z=180
42z+12=180
subtract 12 from 180 then your left with
42z=168
divide 42 on both sides
and you get 168/42 = 4
z=4

y subscript 2 baseline tilde m x subscript 2 baseline plus b
y subscript 2 baseline equals m x subscript 2 baseline plus b
y tilde m x plus b
y = mx + b
Answers
Given: The Table of Values
To Find: The least-squares regression line for the data set in the table by using the desmos graphing calculator.
SolutionThe general form of least-squares regression line is: y = mx + b Where, m is the slope and b is the y-intercept.
Where, m is the slope and b is the y-intercept.By using the desmos graphing calculator, we get
m 2.55 b -6.435 Substitute these Values
y = (2.55)x + (-6.435)
y = 2.55x - 6.435
Answer: A
The expression to generate the parameters and statistics is y tilde m x plus b, the correct option is C.
What is an expression?Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given that;
x subscript 2 baseline y subscript 2 baseline;
1 2
2 9
3 7
4 12
Now,
To find the least-squares regression line for a data set using Desmos, you need to follow these steps:
Enter the data as a table in Desmos. For example, type {1, 2, 3, 4} in the x column and {2, 9, 7, 12} in the y column.
Type y tilde m x plus b in the expression box. This tells Desmos to find the values of m and b that minimize the sum of squared errors between y and y tilde (the predicted values).
Click on the wrench icon next to the expression to see the parameters and statistics. You should see something like this:
m = 2.8 b = -1.6 r² = 0.84
This means that the equation of the least-squares regression line is:
y tilde = 2.8 x - 1.6
And that the coefficient of determination (r²) is 0.84.
Therefore, by expression the answer will be y tilde m x plus b.

To rent a certain meeting room, a college charges a reservation fee of $16 and an additional fee of $6 per hour. The chemistry club wants to spend less than $82 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Answers
Answer:
10 hours
Step-by-step explanation:
For about 10 hours.
6 times 10 = 60
60+16= 76
82=6h+16 (minus 16 from both sides)
6h=66 (divide both sides by 6)
h=11

A. k= 49°
B. RSQ= 157°
explanations:
A. the angle shown is a right angle, right angles are 90°. so to get the measure of angle k you must subtract the already known angle from 90°. thus giving the answer 49°
B. a straight line has a measure of 180°. to get the measure of RSQ, you have to subtract the already known angle from 180°. thus giving the answer 157°.
Given ΔABC with measure of angle B equals 82 degrees comma measure of angle C equals 48 degrees comma and a = 16 inches, what is the length of b?
Answers
Answer:
Side b = 20.68325
Step-by-step explanation:
Because the angles of a triangle will always equal 180 we can determine that angle a is 50 because 82+48+x=180. Then we use the law of sines and figure out that sin82/b=sin50/16. Then you cross multiply and get your answer.

1: y = 2x - 4
2: y=-1/2x+2
3: y=-1/2x+6
4: y = 2x - 12
Answers
Answer:
1: y = 2x -4
Step-by-step explanation:
The perpendicular bisector of the given segment is the line through its midpoint that has a slope that is the opposite reciprocal of the segment's slope.
SlopeThe slope of the given segment can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (6 -2)/(0 -8) = 4/-8 = -1/2
The opposite reciprocal of this is ...
m' = -1/(-1/2) = 2 . . . . (eliminates answer choices 2 and 3)
__
PointThe midpoint of the given segment is ...
(A+B)/2 = (8 +0, 2 +6)/2 = (4, 4)
__
Y-interceptThe y-intercept of the perpendicular bisector can be found from ...
b = y -mx
b = 4 -(2)(4) = -4
Then the equation of the perpendicular bisector is ...
y = 2x -4

y=−8x
−7x+3=−8x
−7x+3+8x=−8x+8x(Add 8x to both sides)
x+3=0
x+3+−3=0+−3(Add -3 to both sides)
