The unshaded regions are quarter circles. Which choice best approximates the area of the shaded region? Use ≈3.14. 24
Answer:
The probability that a point chosen at random will be in the shaded region is 0.25
Step-by-step explanation:
We have been given a small shaded circle inside a larger un-shaded circle. This is shown in the image attached below.
The area of smaller circle is 78.5 squares inches and the area of larger circle is 314 square inches. We have to find the probability that a point chosen at random will be in the shaded region.
Probability is defined as the ratio of Favorable outcome to the Total outcomes. In this case the favorable outcome is that the point should be inside the shaded region i.e. in an Area of 78.5 square inches. And the total outcome is that the point can be anywhere inside the larger circle i.e. within an Area of 314 square inches. Thus the probability that a point chosen at random will be inside the shaded region will be:
[tex]Probability =favorable-Outcome/total outcome[/tex]
[tex]=78.5/314[/tex]
[tex]=0.25[/tex]
Thus, the the probability that a point chosen at random will be in the shaded region is 0.25. This means there is a 25% chance that a randomly chosen point will be inside the shaded region.

Collins Middle School has 240 sixth grade students. If the sixth grade is 30% of the total school, how many students are in the middle school?
270
210
72
800
BRAINLIST, EXTRA POINTS,FIVE STARS, AND A HEART
PLEASE HELP!
Answer:
800
Step-by-step explanation:
We can set up a proportion using the information we are given. We know that 240 students corresponds to 30% and that the total number of students, x, corresponds to 100%
[tex]\frac{240}{x} = \frac{30}{100}[/tex]
Cross multiply and solve:
240 * 100 = 30x
24000 = 30x
800 = x

A bath tub in the shape of a rectangular prism is 20 meter long, 10 meter wide and 5 meter deep. How much water can it hold?
Answer:
1000 meters³
Step-by-step explanation:
20 x 10 x 5 = 1000
the units are in meters and you are measuring the volume so the units is meters³
Volume of rectangular prism is 1000 [tex]m^{3}[/tex]
1000 [tex]m^{3}[/tex] of water can a bath tub hold.
What is a rectangular prism?"A rectangular prism can be defined as a 3-dimensional solid shape which has six faces that are rectangles. A rectangular prism is also a cuboid."
Given
Length of a bath tub = 20 m
Width of a bath tub = 10 m
Height of a bath tub = 5 m
Formula to find the volume of the rectangular prism
Volume of the rectangular prism = length × width × height
= 20 × 10 × 5
=200 × 5
V = 1000 [tex]m^{3}[/tex]
Volume of the rectangular prism = 1000 [tex]m^{3}[/tex]
Hence, Volume of rectangular prism is 1000 [tex]m^{3}[/tex]
1000 [tex]m^{3}[/tex] of water can a bath tub hold.

The perimeter of the rectangle below is 174 units. Find the length of side BC. Write your answer without variables.
The measure of the length of the sides BC of the rectangle will be 24 units.
What is the perimeter of the rectangle?Let L be the length and W be the width of the rectangle.
Then the perimeter of the rectangle will be
Perimeter of the rectangle = 2(L + W) units
The perimeter of the rectangle below is 174 units.
The length is 3z + 3 and the width is 4z.
Then the value of z will be
174 = 2(3z + 3 + 4z)
87 = 7z + 3
7z = 84
z = 12
Then the measure of the length of the sides BC of the rectangle will be
BC = 3z + 3
BC = 3(7) + 3
BC = 21 + 3

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is more than 50.2 min. PX> 50.2)( (Report answer accurate to 2 decimal places.) The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 50.3 and 50.8 min. P(50.3 X50.8)-| Let X have a uniform distribution on the interval (10, 16). Find the probability that the sum of 2 independent observations of X is greater than 29.
Answer:
a) P(X > 50.2) = 0.90
b) P(50.3 < X < 50.8) = 0.25
c) P(X+Y >29) = 0.9167
Step-by-step explanation:
From the given information:
[tex]f(x) = \dfrac{1}{b-a} \ \ \ \ a<x<b[/tex]
[tex]f(x) = \dfrac{1}{52.0-50.0} \ \ \ \ 50.0<x<52.0[/tex]
[tex]f(x) = \dfrac{1}{2} \ \ \ \ 50.0<x<52.0[/tex]
a)
Let X be the random variable that follows a uniform distribution.
Such that [tex]X \sim U (50.0, 52.0)[/tex]
where;
a = 50
b = 52
[tex]P(X> 50.2) = \dfrac{b - x}{b-a}[/tex]
[tex]P(X> 50.2) = \dfrac{52 - 50.2}{52-50}[/tex]
[tex]P(X> 50.2) = \dfrac{1.8}{2.0}[/tex]
P(X > 50.2) = 0.90
b.)
To find the probability that the class length is between 50.3 and 50.8 min.
i.e.
[tex]P(50.3 <X<50.8) = \dfrac{(X_2-X_1)}{(b-a)}[/tex]
[tex]P(50.3 <X<50.8) = \dfrac{(50.8-50.3)}{(52-50)}[/tex]
[tex]P(50.3 <X<50.8) = \dfrac{(0.5)}{(2)}[/tex]
P(50.3 < X < 50.8) = 0.25
c)
Given that:
the interval = (101,16)
The probability that the sum of 2 independent observations of X is greater than 29 can be computed as follows.
here;
[tex]c = \dfrac{a+b}{2}[/tex]
where;
a = 10*2 = 20
b = 16*2 = 32
[tex]c = \dfrac{20+32}{2}[/tex]
c = 52/2
c =26
The required probability:
[tex]P(X+Y >29) = 1 - \dfrac{(b-x)\times 2}{(b-a) \times (b - c)}[/tex]
[tex]P(X+Y >29) = 1 - \dfrac{(32-29)\times 2}{(32-20) \times (32 - 26)}[/tex]
[tex]P(X+Y >29) = 1 - \dfrac{(3)\times 2}{(12) \times (6)}[/tex]
[tex]P(X+Y >29) = 1 - \dfrac{6}{72}[/tex]
P(X+Y >29) = 1 - 0.0833
P(X+Y >29) = 0.9167

Write the following linear equation in function notation y=7x-2
Answer:
The function notation is when we represent one of the coordinate points as a function of the other ones.
In the general case, we will have:
y = f(x)
Now, we have that:
y = 7*x - 2
Then the function notation will be:
y = f(x) = 7*x - 2
or simply
f(x) = 7*x - 2

The circumference of a circle is 15π centimeters. What is the area of the circle in terms of π?
Answer: 7.5²π square centimeters. OR 56.25π cm²
Step-by-step explanation:
Circumference = diameter × π
So the diameter is 15 cm
Area = πr²
Radius is half the diameter, so 15/2 or 7.5
Area = (15/2)²π cm²
What is the missing x-coordinate for a line that has a slope of -2 and goes through the points (5, 1) and (x, -3)
Answer:
X=7
Step-by-step explanation:
we already know the slope is -2, so y=-2x+m
since the line goes through point (5,1)
1=(-2)x5+m
1=m-10
m=11
the equation should be y=-2x+11
-3=2x+11
-14=2x

The office manager for the Metro Life Insurance Company orders letterhead stationery from an office products firm in boxes of 500 sheets. The company uses 6500 boxes per year. Annual carrying costs are $3 per box, and ordering costs are $28. The following discount price schedule is provided by the office supply company: ORDER QUANTITY (BOXES) PRICE PER BOX 200–999 $16 1000–2999 14 3000–5999 13 6000+ 12 Determine the optimal order quantity and the total annual inventory cost.
Answer:
The EOQ formula cannot be used here because the price of the goods varies according to the size of the purchase order. In this case, the order quantity that decreases annual inventory costs is 3,000 units per order, and total annual inventory costs = $89,060.67.
Step-by-step explanation:
if we apply the EOQ formula:
Economic order quantity (EOQ) = √[(2 x S x D)/H]S = ordering cost = $28D = annual demand = 6,500H = holding cost = $3EOQ = √[(2 x $28 x 6,500)/$3] = 348.33 ≈ 348 boxestotal annual inventory cost = [(6,500 / 348) x $28] + [(348 / 2) x $3] + (6,500 x $16) = $522.99 + $522 + $104,000
but if the company tried to benefit from discounts due to higher order quantities, total annual cost would be lower:
[(6,500 / 1,000) x $28] + [(1,000 / 2) x $3] + (6,500 x $14) = $182 + $1,500 + $91,000 = $92,682
[(6,500 / 3,000) x $28] + [(3,000 / 2) x $3] + (6,500 x $13) = $60.67 + $4,500 + $84,500 = $89,060.67

Use the number line to find the coordinate of the midpoint of each segment. Answer and ill give brainliest
Answer:
Line Segment AB = -9.5
Line Segment CD = 2
Line Segment GE = 6.5
The midpoint of the segments using the number line are :
AB = - 9.5CD = 2 AE = -1GE = 6.5Recall the midpoint, M formula ;
M = (x1 + x2) ÷ 2
For the segments ;
Segment AB ;A = -12 ; B = - 7
M = (A + B) / 2
M = (-12 + (-7)) / 2
M = (-12 - 7) / 2
M = - 19 / 2
M = - 9.5
Segment CD;C = -2 ; D = 6
M = (-2 + 6) / 2
M = (-2 + 6) / 2
M = 4 / 2
M = 2
Segment AE ;A = -12 ; E = 10
M = (-12 + 10) / 2
M = - 2 / 2
M = - 1
Segment GE ;G = 3 ; E = 10
M = (3 + 10) / 2
M = 13 / 2
M = 6.5
HENCE, THE midpoint of the segments AB, CD, AE and GE are - 9.5, 2, - 1 and 6.5 respectively .
