The approximate area of the shaded sector is 34.6 in2.
How to calculate the surface area of a composite figure?Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
We are given that;
Angle = 145°
Now,
The area of a sector of a circle is given by the formula A = (θ/360)πr2, where θ is the central angle in degrees and r is the radius of the circle. In this case, θ = 145° and r = 7 in.
Plugging these values into the formula, we get: A = (145/360)π(7)^2. Simplifying, we get: A = 0.4028π(49). Using a calculator, we get: A ≈ 34.6 in2.
Therefore, by the area the answer will be 34.6 in2.

A news reporter states that a study shows that 63% of people prefer vanilla ice cream to chocolate ice cream, plus or minus 2% points. The margin of error in this example is _____.
Answer: 21
Why: 21/2321
Using the concept of a confidence interval, it is that the margin of error in this example is of 2%.
------------------------
A confidence interval for a percentage is written in the following format:
[tex]P \pm M[/tex]
That is, the percentage is of P, plus of minus M points, in which M is the margin of error.
------------------------
In this question, the percentage is 63% plus or minus 2%, thus, the margin of error is of 2%.A similar problem is given at https://brainly.com/question/21496409

According to the triangle inequity if 20 and 25 are the lengths of two sides of a triangle then an inequality that represents all possible lengths for the third side is_____
A. 0
B. 0
C. 5_
D. 5
Answer and explanation:
The inequality theorem states that the sum of the length of two sides of a triangle is greater than the third side of a triangle.
Also the difference of two sides of a triangle is less than the third side
If we apply this theorem here,
Then we say the third side x<20+25 and x>25-20
Therefore x<45 but >5
5<x<45
Possible sides of x include: 6,7,8,9,10,11,12,13,14,15,16,17,18...not equal to 45 or more than

Answer:

Step-by-step explanation:
These are "one-step" equations.
To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.
To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).
Here are more details for the problems on the first page.

Mr. Martinez sells vehicles to 20% of the people that come to the dealership. If 65 people came to the dealership last month, how many vehicles did he sell?
Answer:
13 vehicles
Step-by-step explanation:
Just solve 20% of 65. "Of" means to multiply, and 20% is just 0.2
