The fraction of the circle measured by a sector which subtends an angle; 45° is; 1/8 (one-eighth).
It has been established from circle geometry that the angle subtended at a point is 360°.
On this note, the algebraic sum of angles in a circle is; 360°.In essence, a sector which measures 45° is only 1/8 of the circle.
45/360 = 1/8.Read more on sectors and circles;

I don't understand this: If Kelly spins the spinner 120 times, how many times would you predict the spinner lands on pink based on experimental data? Show your work in the box below the image.
Pink:6
purple:12
yellow:9
Blue:13
The expected value of the spinner landing on pink will be 18.
What is the expected value?The anticipated value is an extension of the weighting factor in statistical inference. Informally, the anticipated value is the simple average of a significant number of outcomes of a randomly selected variable that was separately chosen.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
If Kelly spins the spinner 120 times. The table is given below.
Color Frequency
Pink 6
Purple 12
Yellow 9
Blue 13
Total 40
Then the probability of the pink color will be
p = 6 / 40
p = 0.15
Then the expected value of the spinner landing on pink will be
E(x) = 120 x 0.15
E(x) = 18
The expected value of the spinner landing on pink will be 18.

Hey guy can you pls help me find the area and pls show your working
*links are not allowed*
Step-by-step explanation and Answer :)
So we can split this shape into a few easier shapes to solve the area!
There are multiple combinations:
rectangle, triangle, and another rectangle
rectangle, trapezium
The second option is faster so lets use that :)
[tex]187m^{2}[/tex]
You should draw a dotted line across the top of the rectangle so now there is a rectangle on the bottom and a trapezium on the top!
[tex]A_{square} = b * h\\A_{square} = 16 * 6\\A_{square} = 96m^{2} \\\\\\A_{trap} = \frac{(a + b)h}{2}\\[/tex]
[tex]A_{trap} = \frac{(10 + 16)7}{2}\\\\A_{trap} = \frac{(182)}{2}\\\\A_{trap} = 91 m^{2}[/tex]
96 + 91 = [tex]187m^{2}[/tex]

Step-by-step explanation:
Answer:
5. is C which is 9.
6. is B which is 37.
Step-by-step explanation:
The first on is C. 9 because to find the interquartile range you need to subtract the upper quartile range by the lower quartile range. The upper is 16 and the lower is 7 so you do 16-7 which is 9.
The last question is B. 37 because the lower quartile range is first line in the box plot which is 37.

what are the first four terms of the sequence an=n2+4
Step-by-step explanation:
Given formula
an = n² + 4
Now the first four terms of the sequence are
a1 = 1² + 4 = 5
a2 = 2² + 4 = 4 + 4 = 8
a3 = 3² + 4 = 9 + 4 = 13
a4 = 4² + 4 = 16 + 4 = 20
The terms are
5 , 8 , 13 and 20.
Hi!! Please explain how you got the answer, thanks!! :))
Start out by finding the area of the square.
a = 4²
a = 16
Since all we have to look at is 1/4 of this square, multiply the area by 1/4.
(16)1/4
4
The area of the triangle is 4.
Now we need the area of the circle.
a = πr²
Sub: a = π(2)²
a = π(4)
Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.
a = 4 - 1/4(π(4))
a = 4 - 1/4π x 1
a = 4 - 1/4π
Now this is where it's supposed to go, considering the fact that π isn't given a value.
Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.
Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.
Uhh good luck I guess this math test is weird

A mortgage has an initial balance of $150,000 and is charged 5% yearly interest applied monthly. If a person makes a payment of $1000 each month, which of the following is closest to the mortgage balance after 3 months of payments?

(2)$147,520
(3)$148,160
(4)$148,870
A mortgage loan is termed as a loan that is used to purchase or maintain a home, land or other pieces of real estate.
The borrower agrees to repay the amount of loan to the lender over a period of time, usually in a series of regular installments divided into principal and interest. The property is used as security for the loan.
Calculation of the amount of mortgage is as follows:
[tex]\text{Interest}= \text{Mortgage amount} \times\frac{0.05}{12}\times3[/tex] = 1875
[tex]\text{Principal Pay }= 1000 \times3[/tex] = 3000
Total amount paid = Interest + principal pay = 1875 + 3000 = 4875
Initial balance = 150000
The remaining balance for the mortgage amount = initial balance - the total amount paid.
Amount of mortgage = $ 145125.
Therefore the closest to the mortgage balance after 3 months of payments is
(1) $145,165.

17. There are 1,024 players in a tennis tournament. In each round, half the players are eliminated.
Which function can be used to find the number of players remaining in the tournament at the end of
x rounds?
A f(x) = 1,024(1.50)
B f(x) = 1,024(0.50)*
C f(x) = 1,024(1.05)
D f(x) = 1,024(0.50)x
Answer?
Answer:
1024(0.50)^x
Step-by-step explanation:
Initial value = 1024
Players eliminated per round =half = 50% of players in the round
Using the relation :
A(x) = P(1 - r)^x (decreasing hence, negative)
A(x) = 1024(1 - 50%) ^x
A(x) = 1024(1 - 0.50)^x
A(x) = 1024(0.50)^x
