Answer:
y=7x-65
Step-by-step explanation:
The value of x in the given sector is determined as 7.1.
<h3>Area of the sector</h3>
Total area of the sector = area of the shaded + area of the unshaded
Since shaded and unshaded areas are equal, the value of x is calculated as follows;
πr²θ/360 = πx²60/360 + πx²60/360
πr²θ/360 = 2(πx²θ/360)
πr² = 2(πx²)
r² = 2x²
x² = r²/2
x² = (10²)/2
x² = 50
x = √50
x = 7.1
Thus, the value of x in the given sector is determined as 7.1.

Answer:
A=39.06 Sq Ft
Step-by-step explanation:
We are given with a square which has a side of 6.25 feet. We are asked to determine the area in square feet and Round to the correct significant digits.
Area of square is given as
A= side x side
Side = 6.25 ft
A=6.25 x 6.25
A= 39.0625
Rounding it to the nearest hundredth place
A=39.06 sq ft
Find a common denominator
7/12 + 1/12
= 7/12 + 4/12
=11/12
The percentage of the scores that are between 75.8 and 89 is; 95%
<h3>How to find the percentage from z-score?</h3>
We are given;
Population mean; μ
Standard deviation; σ = 3.3
Thus;
z-score for a mean score of 75.8 is;
z = (75.8 - 82.4)/3.3
z = -2
z-score for a mean score of 89 is;
z = (89 - 82.4)/3.3
z = 2
From online p-value from z-score calculator, the p-value between both z-scores is;
p-value = 0.9545 = 95.45%
Approximating to the nearest percent = 95%
