Find the probability that a
randomly
selected point within the circle falls
in the white area.
r = 4 cm
a = 3.2 cm
S = 4.7 cm
[? ]%
Round to the nearest tenth of a percent.
Answer:
25.54
Step-by-step explanation:
somebody say it on the comments :)
The probability that a randomly selected point within the circle falls in the red-shaded area is 75.61%.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
We need to find the probability that a randomly selected point within the circle falls in the white area.
We have been given the following parameters;
Radius r = 4 cm
a = 3.2 cm
S = 4.7 cm
The area of the circle A = πr²
A = π(4)²
A = 16π square cm
Here, The total number of outcomes = 16π square cm = 50.26 square cm
The side length of the pentagon a = 4.7 cm
The area of the pentagon can be calculated using:
Area = (1/4)√[5(5+2√5)]a²
Plug a = 4.7
Area = (1/4)√[5(5+2√5)](4.7)²
After calculating, we get;
Area = 38.01 square cm
The Total favorable outcomes = 38.01 square cm
The probability = 38.01/50.26
The probability = 0.7561
In percent,
The probability = 75.61%
Therefore, the probability that a randomly selected point within the circle falls in the red-shaded area is 75.61%.

Find the area of the smaller sector.
Round to the nearest tenth.
500
7 1371
Area = [? ]ft2
Answer:
22.2
Step-by-step explanation:
Hello There!
This is the sector area formula
[tex]A=\frac{0}{360} (\pi r^2)[/tex]
where 0 = sector angle
and r = radius
The given sector has a measure of 50 degrees and a radius of 7.13
Knowing this information we plug it into the formula
[tex]A=\frac{50}{360} (\pi 7.13^2)\\\frac{50}{360} =0.1388888889\\7.13^2=50.8369\\50.8369\pi =159.7088316\\159.7088316*0.1388888889=22.18178216[/tex]
so we can conclude that the area of the sector is 22.18178216 ft²
finally we round to the nearest tenth
and get that the answer is 22.2

For a sample with mean = 50 and standard deviation = 10...
A. Find the z-score for each of the following X values:
X = 60
X = 75
X = 30
X = 60 is 1 standard deviation above the mean.
X = 75 is 2.5 standard deviations above the mean.
X = 30 is 2 standard deviations below the mean.
To find the z-score for a particular X value, we use the formula:
z = (X - mean)/standard deviation
where X is the given value, mean is the population mean, and standard deviation is the population standard deviation.
For X = 60:
z = (60 - 50)/10 = 1
Therefore, the z-score for X = 60 is 1.
For X = 75:
z = (75 - 50)/10 = 2.5
Therefore, the z-score for X = 75 is 2.5.
For X = 30:
z = (30 - 50)/10 = -2
Therefore, the z-score for X = 30 is -2.
The z-score represents the number of standard deviations that a particular X value is away from the mean. Since the mean z-score is 0 and a positive z-score means that the X value is above the average.

a. How many selected traveling as their favorite hobby?
Answer:
180 people
Step-by-step explanation:
Total of people surveyed = 1,000
% of people that selected travelling as their favorite hobby = 18 %
Number of people that selected travelling = % that selected travelling of 1,000

Find the equation (in terms of x ) of the line through the points ( − 5 , 4 ) and ( 4 , 0 ) . Express your answer in slope-intercept form
Answer:
Equation = 4x + 9y = 16Step-by-step explanation:
co-ordinate = (-5.4) & (4,0)
slope(m) = (y² - y¹) / (x² - x¹)
slope(m) = (0-4) / (4+5)
slope(m) = -4 / 9
Equation,
y = mx + c
y - 0 = -4/9 (x - 4)
9y = -4x + 16

1. A company has $6582 to give out in bonuses. An amount is to be given out equally to each of the 32 employees.
(a) A manager, Jake, reasoned that since 32 goes into 64 twice, each employee will get about $2000. Is his estimate correct? Why or why not?
(b) How much will each employee receive, rounded to the nearest whole dollar? Leave the remainder undivided. Show your work.
Answer:
Answer:
A) His estimate is incorrect, since he has increased a figure to the amount that each employee would receive.
B) Rounded to the nearest dollar, each employee would receive $ 209.
Step-by-step explanation:
Since a company has $ 6582 to give out in bonuses, and an amount is to be given out equally to each of the 32 employees, and A) a manager, Jake reasoned that since 32 goes into 64 twice, each employee will get about $ 2000 , to determine if his estimate is correct, and B) determine how much will each employee receive, rounded to the nearest whole dollar, the following calculations must be performed:
A)
2000 x 32 = 64000
200 x 32 = 6400
Therefore, his estimate is incorrect, since he has increased a figure to the amount that each employee would receive.
B)
6582/32 = X
208.68 = X
Therefore, rounded to the nearest dollar, each employee would receive $ 209.
Eva earns $500 per month plus $3 for every sale she makes which inequality can she use to find how much she must sale to earn at least $1,200 in a month
Answer:
500 + 3(s) ≥ 1200
Step-by-step explanation:
Ok so the goal is to earn 1,200 / month
We know that she already earns 500/month
So lets do some subtraction
Because she needs to make ATLEAST 1,200, well use either ≤ or ≥
Lets call (s) the number of sales she makes
Lets form the inequality
500 + 3(s) ≥ 1200

Step-by-step explanation:
Perimeter of base = 8+5+5=18 ft
Height = 7 ft
Base area = 1/2x8x3=12ft²
SA= (8x7)+(12+12)+2(5x7)=56+24+70=150 ft²
*There are several different way to figure out the surface area, so I’m not sure exactly how they want it displayed. 150 is the answer though. Plus, I think there was supposed to be an addition sign between the first two parentheses.
