Answer:
9. 40°
10. 50°
11. 270°
12. 310°
Step-by-step explanation:
m∠BPC = 40° because it is complementary to ∠APB, which is 50°.
Arc AB is 50° because it will be equal to the central angle, which is 50°.
Arc ADC is 270° because it will be equal to the central angle, which is 270°.
Arc ADB is 310° because it will be equal to the central angle, also 310°.
The standard deviation from the mean of the data with a variance of 36 is: B. 6.
<h3>What is Standard Deviation?</h3>
Standard deviation can be described as the average of the distance each of the value lies from the mean of the data.
The standard deviation is the square root of the variance.
Variance of the data is given already as 36.
Standard deviation = √36 = 6.
The answer is B. 6.

Radii and chord form an equilateral triangle. The angle of the larger segment is
.
The length of the larger segment is
Answer:
6 houses
Step-by-step explanation:
Formula:
V = 1/3 * b * h
Plug in what we know:
35 = 1/3 * b * 7
Multiply 7 * 1/3:
35 = 2 1/3 * b
Multiply:
35 = 2 1/3b
Divide 2 1/3 to both sides:
b = 15
