Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is either in the triangle or in the circle.
Answer Options:
0.73
0.35
0.33
0.26
Answer:
0.26
Step-by-step explanation:
In geometric probability, the probability of an event is based on a ratio of geometric measures such as length or area.
The area model is used here. The measures of various dimensions of the sample space and the included figures are given.
The sample space is the area of the large rectangle.
Find the area of the sample space.
Substitute the known values for the length, l=16
m, and width, w=11.8 m, into the formula for the area of a rectangle, A=lw
.
A=(16)(11.8)=188.8
m2
The probability that a randomly chosen point will lie either inside the triangle or inside the circle is the sum of the individual probabilities.
The probability that a randomly chosen point will lie inside the triangle is equal to the ratio of the area of the triangle to the area of the large rectangle.
Find the area of the triangle.
The height of the triangle equals 11.8−7.3=4.5
m
.
Substitute the known values for the base, b=8
m, and height, h=4.5 m, into the formula for the area of a triangle, A=12bh
.
A=12(8)(4.5)=18
m2
Find the probability that a point chosen randomly inside the rectangle is in the triangle.
P1=18188.8
The probability that a randomly chosen point will lie inside the circle is equal to the ratio of the area of the circle to the area of the large rectangle.
Find the area of the circle.
The radius is half of the diameter. So, r=6.22=3.1
m
.
Substitute the known value for the radius, r=3.1
m, into the formula for the area of a circle, A=πr2
.
A=π(3.12)=9.61π
m2
Find the probability that a point chosen randomly inside the rectangle is in the circle.
P2=9.61π188.8
Sum the individual probabilities to find the probability that a point chosen randomly inside the rectangle is either in the triangle or in the circle.
P=P1+P2
=18188.8+9.61π188.8
=18+9.61π188.8≈0.26
Therefore, the probability that a point chosen randomly inside the rectangle is either in the circle or in the triangle is about 0.26
.
The probability that a point chosen randomly inside the rectangle is either in the triangle or in the circle is 0.26. Option fourth is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is the problem of geometric probability:
Area of rectangle = 16×11.8 = 188.8 square meters
Area of circle = π(6.2/2)² = 30.190 square meters
Area of triangle = (1/2)(8×[11.8-7.3]) = 18
P(triangle) = 18/188.8 = 0.095
P(circle) = 30.190/188.8 = 0.159
P = P(triangle) + P(circle) = 0.095 + 0.159 = 0.254 ≈ 0.26
Thus, the probability that a point chosen randomly inside the rectangle is either in the triangle or in the circle is 0.26. Option fourth is correct.

1. A slice is being made to a cube. For each slice—
• Describe the two-dimensional figure resulting from the described slice. Use the specific name when possible.
• Determine whether a different slice can produce a congruent two-dimensional figure. If so, describe or sketch an example of the slice. If not, explain why not.
(a) a slice parallel to the base
(b) a slice that contains and
(c) a slice that contains and vertex F
(a.) A slice parallel to the base would result in two rectangular prisms, as opposed to a cube now. These two rectangular prisms would be congruent to each other as it is a perfect slice through the middle.
(b) A slice that contains and AE and DH will make a slanted cube, meaning it will turn into a cubic pyramid.
(c.) A slice that will contain and vertex F will make the cut the figure in half going slanted. They will technically be congruent, although there is no name for this figure.

Answer:
Step-by-step explanation:
4 year Public University
Tuition and fees $ 8500
Room and board $ 6700
Books and supplies $1250
misc expenses $ 700
Total for 1 year
8500+6700+1250+700
= $ 17150
Total for 4 years 4* 17150 = $68600
4 year Private University
Tuition and fees $ 25100
Room and board $ 8000
Books and supplies $ 1300
misc expenses $ 750
Total for 1 year
25100+8000+1300+750
= $ 35150
Total for 4 years 4* 35150 = $ 140600
2 Year Community College
2 Year Community College
Tuition and fees $ 4400
Room and board $ 5000
Books and supplies $ 1100
misc expenses $ 800
Total for 1 year
4400+5000+1100+800
= $ 11300
Total for 2 years 2* 11300 = $ 22600
now given
kari will get $4500 in scholarships and grants yearly and $1500 yearly through work study program
so in total kari will get in financial aid = $6000 yearly
so in 2 years she will get total = 2*6000 = $12000 financial aid
kari's estimated cost per year = total fee of college for 1 year - total financial aid for 1 year
= $11300 - $ 6000 = $5300
Kari's estimated cost per year = $5300
then estimated cost for two years = 2* 5300 = $10600
given Kari's family will contribute $3000 yearly
so for two years Kari will get = 2*3000 = $6000 from family
If kari has 1 year to save for 1st year's contribution then
a) kari has $0 in savings
kari needs to save for year = estimated cos per year - contribution from family per year
= $5300 - $ 3000 = $2300
as kari has $0 savings so kari needs to save $2300 in 1 year
so kari needs to save an amount = 2300/12 = $191.666667 monthly
b) kari has $1000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $1000
= $1300
so kari needs to save an amount of = 1300/12 = $108.3333333 monthly
c) Kari has $2000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $2000
= $300
so kari needs to save an amount of = 300/12 = $25 monthly

Midpoints calculated, plotted and connected to make the triangle DEF, see the attached.
D= (-2, 2), E = (-1, -2), F = (-4, -1)3.
As per definition, midsegment is parallel to a side.
Parallel lines have same slope.
Find slopes of FD and CB and compare.
m(FD) = (2 - (-1))/(-2 -(-4)) = 3/2m(CB) = (1 - (-5))/(1 - (-3)) = 6/4 = 3/2As we see the slopes are sameFind the slopes of FE and AB and compare.
m(FE) = (-2 - (- 1))/(-1 - (-4)) = -1/3m(AB) = (1 - 3)/(1 - (-5)) = -2/6 = -1/3Slopes are sameFind the slopes of DE and AC and compare.
m(DE) = (-2 - 2)/(-1 - (-2)) = -4/1 = -4m(AC) = (-5 - 3)/(-3 - (-5)) = -8/2 = -4Slopes are same4.
As per definition, midsegment is half the parallel side.
We'll show that FD = 1/2CB
FD = [tex]\sqrt{(2+1)^2+(-2+4)^2}[/tex] = [tex]\sqrt{3^2+2^2}[/tex] = [tex]\sqrt{13}[/tex]CB = [tex]\sqrt{(1 + 5)^2+(1+3)^2}[/tex] = [tex]\sqrt{6^2+4^2}[/tex] = 2[tex]\sqrt{13}[/tex]As we see FD = 1/2CBFE = 1/2AB
FE = [tex]\sqrt{(-4+1)^2+(-1+2)^2}[/tex] = [tex]\sqrt{3^2+1^2}[/tex] = [tex]\sqrt{10}[/tex]AB = [tex]\sqrt{(-5 -1)^2+(3-1)^2}[/tex] = [tex]\sqrt{6^2+2^2}[/tex] = 2[tex]\sqrt{10}[/tex]As we see FE = 1/2ABDE = 1/2AC
DE = [tex]\sqrt{(-2+1)^2+(2+2)^2}[/tex] = [tex]\sqrt{1^2+4^2}[/tex] = [tex]\sqrt{17}[/tex]AC = [tex]\sqrt{(-5 +3)^2+(3+5)^2}[/tex] = [tex]\sqrt{2^2+8^2}[/tex] = 2[tex]\sqrt{17}[/tex]As we see DE = 1/2AC(10-1)

It can be written as
[tex]\begin{bmatrix}1&4\\3&2\end{bmatrix}\begin{bmatrix}8\\1\end{bmatrix}=\begin{bmatrix}1\times 8+4\times 1\\3\times 8+2\times 1\end{bmatrix}[/tex]
[tex]\begin{bmatrix}1&4\\3&2\end{bmatrix}\begin{bmatrix}8\\1\end{bmatrix}=\begin{bmatrix}8+4\\24+2\end{bmatrix}[/tex]
[tex]\begin{bmatrix}1&4\\3&2\end{bmatrix}\begin{bmatrix}8\\1\end{bmatrix}=\begin{bmatrix}12\\26\end{bmatrix}[/tex]
The element of first row and first column is 12. So, the value of [tex]a_{11}[/tex] is 12.
Therefore, the correct option is B.

Miguel measures two sides of a sail: 15 feet and 8 feet. Which could be the measurement of the third side?
A. 6 feet B. 10 feet C. 23 feet D. 30 feet
Answer:
10
Step-by-step explanation:
6 feet and 10 feet are the possible measurement of the third side.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To determine the possible measurement of the third side of the sail, we can use the triangle inequality theorem,
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's check the answer choices using the triangle inequality theorem:
A. 15 + 8 > 6
23 > 6
This is true, so 6 feet could be a possible measurement of the third side.
B. 15 + 8 > 10
23 > 10
This is true, so 10 feet could be a possible measurement of the third side.
C. 15+8 > 23
23=23
This is false, so 23 feet is not possible measurement of the third sid
D. 15+8 > 30
23>30
This is false, so 30 feet is not possible measurement of the third side
Hence, 6 feet and 10 feet are the possible measurement of the third side.
