A square is inscribed in a circle. A point in the figure is selected at random. Find the probability that the point will be in the shaded region.
The probability of the point will be in the shaded region is 0.64 or 64%.
A square is inscribed in circle. Probability of point to be pick from the square to be find out.
Venn diagram are the Figures of probabilities to understand better.
Here, diameter of circle = d and radius r =d/2, edge of the square = a
By Pythagorean theorem,
a²+a²=d²
2a²= (2r)²
a²=2r²
Area of the square =2r²
Area of the circle = πr²
Now probability = Area of the square/Area of the circle
= 2r²/πr²
= 2/π
= 0.64
Thus, The probability of the point will be in the shaded region is 0.64 or 64%.

Scotty is planning to order 1 cubic yard of topsoil for his 15' by 24' garden expecting that if evenly spread, he would end up with 2 inches of topsoil. Is he correct? Explain.
2 inches = 0.1666 feet
15 x 24 x 0.1666 = 59.98 cubic feet
1 cubic yard = 27 cubic feet
59.98 is greater than 27 so 1 cubic yard of topsoil will not be enough
In a recent local taste contest testing Coke against Pepsi it was found that 3/5 of all people surveyed preferred to taste the Coke. if 7,500 people were in the survey how many chose Pepsi ?
Answer: 3,000
Step-by-step explanation:
Given : In a recent local taste contest testing Coke against Pepsi it was found that [tex]\dfrac{3}{5}[/tex] of all people surveyed preferred to taste the Coke.
If 7,500 people were in the survey , then the number of people chose coke will be :-
[tex]\dfrac{3}{5}\times7500=3\times1500=4500[/tex]
Now, the number of people chose Pepsi = 7,500-4,500=3,000
Hence, there are 3,000 people who chose Pepsi.

A company that packages cold cuts needs to transport the packaged meat to the supermarket.it will cost $1,200 to rent a truck,and it will cost an additional $100 for every 50 pounds transported.which equation represents the transport cost for every 50 pounds if cold cuts transported? The options are
A) y=1,200-100x
B) y= 1,200+100x
C) y=1,200x +100
D) y=100x-1,200
it to calculate the cost of $100 for every 50lbs, you would use 100x
then you need to add that to the 1200
so the equation would be y = 1200+100x

A single person earns a gross biweekly salary of $780 and claims 6 exemptions. What is the person's net pay?
a.
It is the same as the gross pay.
b.
It is $11 more than the gross pay.
c.
It is $11 less than the gross pay.
d.
It is $13 less than the gross pay
Answer:
A. It is the same as the gross pay.
Explanation:
To get the amount of income tax withheld, we use the table attached.
We are given that:
1- This biweekly gross salary is $780, therefore, we will go to the row having a minimum payment of $780 (red border)
2- The number of claimed allowances is 6, therefore, we will go to the column with 6 claimed allowances (blue border)
We now find the intersection between the row and the column. As we can see in the table, it is zero.
This means that the deducted taxes based on the givens is zero which means that the net pay is the same as the gross pay.
Hope this helps :)
Final answer:
To calculate the net pay, deduct the taxes and other deductions from the gross salary. Since the deductions will be greater than zero, the net pay will be $11 less than the gross pay.
Explanation:
To calculate the net pay, we need to deduct the taxes and other deductions from the gross salary. The main deductions to consider are Social Security, Medicare, and federal and state taxes. Let's break it down.
Calculate Social Security deduction: Gross biweekly salary x 6.2%.Calculate Medicare deduction: Gross biweekly salary x 1.45%.Calculate federal and state taxes: Gross biweekly salary x 15%.Add up all the deductions.Subtract the total deductions from the gross salary to find the net pay.
Since the deductions will be greater than zero, the net pay will be $11 less than the gross pay. Therefore, the correct answer is option c. $11 less than the gross pay.
a study of the amount of time it takes a mechanic to rebuild the transmission for a 1992 chevrolet cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 64 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 8.6 hours
Since we know the population standard deviation and the sample size is above 30, then we use the z statistic. The formula for z score is:
z = (x – u) / s
where,
x = the sample mean or sample value = 8.6 hours
u = the population mean = 8.4 hours
s = the standard deviation = 1.8 hours
Substituting into the given equation:
z = (8.6 – 8.4) / 1.8
z = 1.11
Using the standard probability distribution tables for z, a value of z = 1.11 has a probability of:
p = 0.8665
However this is still not the correct answer since this refers to the left of z. What we are trying to find is to the right of z since problem ask for exceeds 8.6 hours, therefore the correct answer is:
P (x>8.6 hours) = 1 – 0.8665
P (x>8.6 hours) = 0.1335
Therefore there is a 13.35% chance that the mean rebuild time is greater than 8.6 hours.

A.) (-1,0)
B.) (-1,7)
C.) (-1,2)
D.) (2,-1)
Answer:
C.) (-1, 2)
Step-by-step explanation:
You can plot the points on a graph, or you can just find the midpoint:
midpoint = (O + N)/2 = ((-1, 9) +(-1, -5))/2 = (-1-1, 9-5)/2 = (-2, 4)/2
midpoint = (-1, 2)

Convert r =-72/12+6 sin theta to Cartesian form.
Answer:
The answer is b. [tex]4x^2+3y^2-24y-144=0[/tex]
Step-by-step explanation:
The equation is:
[tex]r=\frac{-72}{12+6\sin(\theta)}[/tex]
Cross multiply;:
[tex]r(12+6\sin(\theta)=-72[/tex]
Expand;:
[tex]12r+6r\sin(\theta)=-72[/tex]
Divide through by 6;:
[tex]2r+r\sin(\theta)=-12[/tex]
[tex]2r=-12-r\sin(\theta)[/tex]
Substitute;:
[tex]y=r\sin(\theta), r=\sqrt{x^2+y^2}[/tex]
[tex]2\sqrt{x^2+y^2}=-12-y[/tex]
Square both sides;:
[tex](2\sqrt{x^2+y^2})^2=(-12-y)^2[/tex]
[tex]4(x^2+y^2)=144+24y+y^2[/tex]
[tex]4x^2+4y^2=144+24y+y^2[/tex]
Simplify;:
[tex]4x^2+3y^2-24y-144=0[/tex]

Quadrilateral STWR is inscribed inside a circle as shown below. Write a proof showing that angles T and R are supplementary. Circle Q is shown with an inscribed quadrilateral labeled RSTW.
Answer:
Step-by-step explanation:
Arc STR measures twice the measure of angle R, and arc WRS measures twice the measure of angle T.
STR = 2 x ∠R and WRS = 2 x ∠T --- This is because of the Inscribed Angle Theorem
If the measure of arcs STR and WRS are added together, the total would be 360° since a full circle is made up of 360°.
So mSTR + mWRS = 360°
Substituting the angle measures of R and T in for the arcs, the equation becomes:
2 • ∠R + 2 • ∠T = 360°
Simplifying further:
2 • [∠R + ∠T] = 360°
∠R + ∠T = 360° / 2
∠R + ∠T = 180° - This proves that opposite angles of a quadrilateral inscribed in a circle are supplementary.

The total cost of the least is $19,920.
Here,
lease a car at $415 per month for 4 years.
We have to find the total cost of the least.
What is Multiplication?
Multiplication is the process of calculating the total of one number multiplied by another.
Now,
lease a car at $415 per month for 4 years.
1 years = 12 month
4 years = 4 x 12 = 48 months.
Hence, total cost of the least = $415 x 48
= $19,920
So, The total cost of the least is $19,920.
