O
10п cm2
O 20 п cm
50 п cm2
O 100 п cm2
Answer:
A = 100 pi cm^2
Step-by-step explanation:
A = pi(r^2)
A = pi(10^2)
A = pi(100)
A = 314.16 '
Convert to pi units.
314.16 ---> 100pi cm^2
Answer:
Half of 20 is 10(New radius)
10^2(radius squared) = 100
100pi is your next step, which is 100π cm2
Formula area of a circle:

In a game show, a contestant receives a prize that has a % chance of being worth $ and a % chance of being worth $. What is the expected value of winning a prize?
Answer:
112
Step-by-step explanation:
Expected Value is anticipated value, calculated by multiplying each of possible outcomes with their probability of occurrence.
If Price has = 60% chance of value 120 , & 40% chance of value 100
Expected Value = Sum ( Probability of outcome x Payoff )
E (X) = Σ [ xi . PR ( xi ) ] = x1. Pr (x1) + x2 . Pr (x2)
= 0.6 (120) + 0.4 (100) = 72 + 40
= 112

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
It is given that the base is 6 ft and the height is 8 ft then the value of hypotenuse or x will be calculated as below:-
The value of x is calculated as:-
H² = P² + B²
x² = 6² + 8²
x² = 36 + 64
x² = 100
Simply the square root to find the value of x.
x = √100
x = 10

Question 7 of 10
For which sample size (n) and sample proportion (6) can a normal curve be
used to approximate the sampling distribution?
O A. n = 45; Ø = 0.8
O B. n = 90; 0 = 0.9
O C. n = 90; i = 0.8
D. n = 45; P = 0.9
SUBMIT
Answer:
C. n = 90; p = 0.8
Step-by-step explanation:
According to the Central Limit Theorem, the distribution of the sample means will be approximately normally distributed when the sample size, 'n', is equal to or larger than 30, and the shape of sample distribution of sample proportions with a population proportion, 'p' is normal IF n·p ≥ 10 and n·(1 - p) ≥ 10
Analyzing the given options, we have;
A. n = 45, p = 0.8
∴ n·p = 45 × 0.8 = 36 > 10
n·(1 - p) = 45 × (1 - 0.8) = 9 < 10
Given that for n = 45, p = 0.8, n·(1 - p) = 9 < 10, a normal distribution can not be used to approximate the sampling distribution
B. n = 90, p = 0.9
∴ n·p = 90 × 0.9 = 81 > 10
n·(1 - p) = 90 × (1 - 0.9) = 9 < 10
Given that for n = 90, p = 0.9, n·(1 - p) = 9 < 10, a normal distribution can not be used to approximate the sampling distribution
C. n = 90, p = 0.8
∴ n·p = 90 × 0.8 = 72 > 10
n·(1 - p) = 90 × (1 - 0.8) = 18 > 10
Given that for n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution
D. n = 45, p = 0.9
∴ n·p = 45 × 0.9 = 40.5 > 10
n·(1 - p) = 45 × (1 - 0.9) = 4.5 < 10
Given that for n = 45, p = 0.9, n·(1 - p) = 4.5 < 10, a normal distribution can not be used to approximate the sampling distribution
A sampling distribution Normal Curve
45 × (1 - 0.8) = 9
90 × (1 - 0.9) = 9
90 × (1 - 0.8) = 18
45 × (1 - 0.9) = 4.5
Now we will investigate the shape of the sampling distribution of sample means. When we were discussing the sampling distribution of sample proportions, we said that this distribution is approximately normal if np ≥ 10 and n(1 – p) ≥ 10. In other words
Therefore;
A normal curve can be used to approximate the sampling distribution of only option C. n = 90; p = 0.8
If the fifth term of an arithmetic sequence is 11 and the common difference is 4, then the sixth term of the sequence is _______.
Answer:
15Step-by-step explanation:
11+4=15
The sixth term of an arithmetic sequence with fifth and common difference of 11 and 4 respectively is 15
Arithmetic sequence formulaaₙ = a + (n - 1)d
where
a = first termd = common differencen = number of termsTherefore,
11 = a + 4d
d = 4
Hence,
11 = a + 4(4)
11 = a + 16
a = 11 - 16
a = -5
Therefore, the sixth term is as follows
a + 5d = a₆
-5 + 5(4) = a₆
a₆ = -5 + 20
a₆ = 15

Answer:
h = 0
Step-by-step explanation:
Ok, I got you.
To begin, everyone knows that y = mx + b is the equation for any slope-intercept form problem.
y = the y - value of a point
m = the slope
x = the x - value of a point
b = the y - intercept (or where the line starts)
So, you are given the slope, and you're given the y - value. But, you don't have the x - value in the second point.
That mean's you're going to have to use the first point, because you're given both the x and y values, to find the y - intercept.
Simply, plug in the y and x values where they belong.
2 = 6 (-1) + b
(Remember the 6 is the slope)
Now, solve for b.
2 = -6 + b
8 = b
Now, you know the y - intercept.
So, you can find the value of h in the second point. Since you don't know the x - value, plug in what you do know and solve for y.
So...
8 = 6 (x) + 8
(Remember 6 is the slope and 8 is the y - intercept)
Now, solve for x.
8 = 6x + 8
0 = 6x
0 = x
The value of h is 0.

arithmetic sequences
Answer:
For 1, you'd have 14, 7, 0, -7
Step-by-step explanation:
Remember arithmetic sequences are adding the same thing (the difference) over and over and over. So in this case, you have the following:
1st blank: 14 + d
2nd blank: 1st blank + d OR (14 + d) + d = 14 + 2d
the -7 then is the 2nd blank + x OR [(14 + d) + d] + d
So you are adding 3d to the 14 to get to the -7. Set that up as the equation:
14 + 3d = -7.
When you solve for d, you get -7. That's what you'll add to 14 to get the first number, then add it again to get the second, etc.
The coefficient in front of d will always be one more than the number of spaces since you are adding the difference to find each blank IN ADDITION TO the last number in the sequence. So #4 would be setup like this:
2 + 5d = 57
Good luck!

The accompanying diagram shows a revolving door
with three panels, each of which is 4 feet long.
What is the width, w, of the opening between x and
y, to the nearest tenth of a foot?
Answer:
7 ft.
Step-by-step explanation:
Please see the attached image.
I named the center Z btw
Because the circle is split into three congruent angles, each angle is 360/3=120°.
After dropping an altitude on the bottom triangle, the angle is bisected, so 120/2=60°.
By dropping the altitude, we also created a 30-60-90 triangle. By now you have probably learned the proportions for the sides of a 30-60-90 triangle, but if you haven't,
the side opposite the 30° angle is half the hypotenuse, and the side opposite the 60° angle is the other leg multiplied by √3.
So ZW is 4/2=2, and WY is 2√3.
XW=WY, so XY=2√3*2=4√3
4√3 is approximately 7.
7 ft.
The three panels are divided into three equal parts. This mean that the central angle from each panel is 120 degrees. So, the side length of w and the length of curve xy is 7 feet and 8 feet
Let the center of the circle be O (see attachment).
So:
[tex]\angle XOY = \frac{360}{3} = 120^o[/tex] ---- because the circle is divided into 3 equal parts
Considering [tex]\triangle XOY[/tex]
[tex]\angle W O Y = \frac{\angle X O Y}{2}[/tex]
[tex]\angle WOY = \frac{120}{2} = 60[/tex]
Considering [tex]\triangle WOY[/tex]
[tex]\sin(60) = \frac{wy}{yo}[/tex]
Where:
[tex]yo= 4[/tex]
So, we have:
[tex]\sin(60) = \frac{wy}{4}[/tex]
[tex]0.8860 = \frac{wy}{4}[/tex]
Multiply through by 4
[tex]wy = 4 * 0.8660[/tex]
[tex]wy = 3.464[/tex]
Because w divides xy into w equal parts
[tex]wx = wy = 3.464[/tex]
The length of w is:
[tex]w =wx + wz[/tex]
[tex]w = 3.464+3.464[/tex]
[tex]w = 6.928[/tex]
Approximate
[tex]w = 7[/tex]
Next, is to calculate arc length xy
This is calculated as follows:
[tex]xy = \frac{\theta}{360} * 2\pi r[/tex]
Where:
[tex]\theta = \XOY = 120^o[/tex]--- central angle
So, we have:
[tex]xy = \frac{\theta}{360} * 2\pi r[/tex]
[tex]xy = \frac{120}{360} * 2 * 3.142 * 4[/tex]
[tex]xy = \frac{1}{3} * 25.136[/tex]
[tex]xy = 8.33[/tex]
Approximate
[tex]xy = 8[/tex]
Hence, the side length of w and the length of curve xy is 7 feet and 8 feet respectively.

Write the standard form equation (Ax + By + C =0) for a line that is perpendicular to
y= 2x + 7 and has the same y-intercept as the line y=5x - 5.
Put only the coefficients for A, B and C
Answer:
A = 1
B = 2
C = 10
Step-by-step explanation:
slope intercept form is
y = mx + b
m is the slope
b is the y-intercept
The slopes of parallel lines are negative reciprocals
------------------------------
y = 2x + 7
slope = 2
slope of perpendicular line is the negative reciprocal of 2
slope = -1/2
y = 5x - 5
y-intercept is -5
-----------------------
slope intercept form of perpendicular line
using slope = -1/2 and y-intercept = -5
y = -(1/2)x - 5
Change to standard form:
multiply both sides by 2
2y = -x - 10
Add x + 10 to both sides
x + 2y + 10 = 0
Therefor
A = 1
B = 2
C = 10
