Answer:
201.45 cm²
Step-by-step explanation:
The whole circle has an area of π(9)² cm², or 81π cm². The shaded part represents all of the circle except for the chunk swept out by sector XZ.
Sector XZ sweeps out 75°, which represents 75/360 of the whole circle, or, simplified, 15/72. That means the shaded area must represent the other 57/72. To find the area then, we can just multiply that fraction by 81π:
[tex]81\pi\cdot\frac{57}{72}=9\pi\cdot\frac{57}{8}[/tex]
Using π ≈ 3.14 and crunching the numbers out gives us a result of approximately 201.45 cm².

Solve for the value of z.
Answers
Answer:
z=75
Step-by-step explanation:
Answer:Z=75
Step-by-step explanation: Since the line is a straight angle, and all straight angles are equal to 180 degrees, you can start building an equation by setting both 101 degrees and (z+4) degrees to equal 180.
Your equation will then be (z+4)+101=180
Add like terms to get z+105=180
Subtract using the subtraction property of equality to get z=75

Can a set of data have more than one line of best fit? Why or why not?
Answers
Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software. A straight line will result from a simple linear regression analysis of two or more independent variables. A regression involving multiple related variables can produce a curved line in some cases.

Step 1: Simplify both sides of the inequality.
−6x−4≥−6x−4
Step 2: Add 6x to both sides.
−6x−4+6x≥−6x−4+6x
−4≥−4

What is the slope of the line that passes through the points (48, 10) and (-36, 17)?
Answers
Answer:
y = m x + b equation of a straight line
m = (y2 - y1) / (x2 - x1) slope of line
m = (17 - 10) / (-36 - 48) = 7 / -84 = -1 / 12
y = -x / 12 + b equation of line
Or b = y + x / 12
If y = 10 and x = 48 then b = 10 + 48 / 4 = 14
if y = 17 and x = -36 then b = 17 - 36 / 12 = 14
So b = 14 and y = -x / 12 + 14
