Roughly 75% of students take the bus to school. If you were to ask 9 students in your class, what is the probability that at most 8 of them take the bus to school?
77.9%
90.4%
22.5%
92.5%
The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%
How to find the probability?
We know that roughly 75% of the students take the bus, then, if we select a student at random.
There is a probability of 0.75 that the student takes the bus.There is a probability of 0.25 that the student does not take the bus.The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:
p = (0.75)^9 = 0.075
Then we have:
P = 1 - 0.075 = 0.925
The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

Answer:
Step-by-step explanation:
You can break the entire figure into two semi-circles, two triangles, and a rectangle.
The area of a semi-circle is 1/2 the area of a full circle. The area of a circle is πr^2. The area of the semi-circle is therefore:
[tex]\pi r^2/2=\pi (10^2)/2=50\pi[/tex]
The other semi-circle also contributes a value of 50π.
Moving on to the triangle, we must use Pythagorean's Theorem to find the value of the base:
[tex]a^2+b^2=c^2[/tex]
[tex]11^2+b^2=20^2[/tex]
[tex]121+b^2=400[/tex]
[tex]b^2=279[/tex]
[tex]b=\sqrt{279}[/tex]
The area of a triangle is:
[tex]Area=b*h/2[/tex]
[tex]A=(\sqrt{279} *11)/2[/tex]
The other triangle also contributes the same area.
Finally, the rectangle. To find the length of the rectangle, we must subtract the base of the triangle from 22. The length is:
[tex]l=22-\sqrt{279}[/tex]
The area of a rectangle is:
[tex]Area=l*w[/tex]
[tex]A=(22-\sqrt{279} )*(11)[/tex]
The total area of the figure is:
[tex]Area=2*(50\pi) +2*(\sqrt{279} *11/2)+11*(22-\sqrt{279} )[/tex]
[tex]Area=100\pi +11*\sqrt{279} +11*(22-\sqrt{279} )[/tex]
[tex]Area=100\pi +242[/tex]
[tex]Area=556.2[/tex]
Answer:
556.2 unit square
Step-by-step explanation:
Solution given:
Area of left semi circle= ½*πr²
where r is radiussince diameter is given 20.
so radius =diameter/2=20/2=10
substituting value
Area of left semi circle =½*π*10²=50π unit square
Since
Right semi circle's diameter is same as left semi circle
so
it's area will also be same.
Area of right semi circle= 50π unit square
Again
Area of middle rhombus= base* height
where base=22 and height is 11
substituting value
Area of middle rhombus=22*11 =242 square units
Now
Total Area=Area of left semi circle+Area of right semi circle+ Area of middle rhombus
Total Area= 50π+50π+242=556.159 unit square in nearest 10 is 556.2 unit square

Hello!
Step 1: Plot the points
We are first going to plot the points on the coordinate graph and connect the points to create a shape.
Refer to attachment titled "Step 1"
Step 2: Box the shape
Since this is an irregular shape, I'm going to make a box around the shape and subtract the area of the empty spaces to find the area of the original polygon.
Refer to attachment titled "Step 2"
Step 3: Area of Edges
We are going to find the area of the shapes A, B, and C and subtract them from the area of the big box to find the area of the polygon.
Area of a triangle = 1/2(base x height)
Area of Box = 6 un x 7 unArea of Box = 42 un²Area of A:
Area A = 1/2(4 un x 2 un)Area A = 1/2(8 un²)Area A = 4 un²Area of B:
Area B = 4 un x 4 unArea B = 16 un²Area of C:
Area C = 1/2(2 un x 3 un)Area C = 1/2(6 un²)Area C = 3 un²Step 4: Area of the polygon
Now, we can simply subtract the values of A, B, and C from the box to get the area of the polygon.
Area Polygon = Box - A - B - CArea Polygon = 42 un² - 4 un² - 16 un² - 3 un²Area Polygon = 38 un² - 16 un² - 3 un²Area Polygon = 22 un² - 3 un²Area Polygon = 19 un²The area of the polygon is 19 un²

The radius of the inner circle of a tile pattern shown is x inches. Write a polynomial in standard form to represent the area of the space between the inner and outer circle.
Answer:
Area of a circle:
[tex]A=\pi r^2[/tex] (where r is the radius)
Area of largest (outer) circle:
[tex]\implies A=\pi (x+6)^2[/tex]
Area of inner circle:
[tex]\implies A=\pi x^2[/tex]
Area of space between the inner and outer circle:
[tex]\implies \pi (x+6)^2-\pi x^2[/tex]
[tex]\implies \pi [(x+6)^2- x^2][/tex]
[tex]\implies \pi (x^2+12x+36- x^2)[/tex]
[tex]\implies 12\pi x+36\pi[/tex]
Factored:
[tex]\implies 12\pi (x+3)[/tex]
A cylindrical barrel has a radius of 5.7 ft and a height of 8.4 ft. Tripling which dimension(s) will triple the volume of the barrel?
Answer:
tripling the height (8.4 ft) will triple the volume of the barrel (from 857.39 to 2,572.17)
Step-by-step explanation:
By Tripling the height we can triple the volume of the barrel.
What is the volume of a cylinder?In geometry, a cylinder's volume is referred to as its capacity, which aids in determining how much material it can carry.
Given, A cylindrical barrel has a radius of 5.7 ft and a height of 8.4 ft.
From the general formula of volume of cylinder = πr²*h
The volume of the given cylinder = π * (5.7)² 8.4
The volume of the given cylinder = 856.95 ft³
As we can see that the volume of a cylinder is directly proportional to its height of the cylinder.
Therefore, The barrel's volume can be tripled by tripling the height.

The volume of prism having its base a right angled triangle is 864cm^3.if the length of the sides containing the right angle are 6cm and 8cm calculate the height of the prism.
Answer:
height: 36 cm
Step-by-step explanation:
volume of triangle prism = 0.5 * base * altitude * height
using the formula:
0.5 * 8 * 6 * height = 864
24 * height = 864
height = 864/24
height = 36 cm
Answer:
36 cm
Step-by-step explanation:
volume of a triangular prism = area of triangle x height of prism
area of triangle = 1/2 x base x height
Therefore, given the perpendicular sides of the triangle are 6 cm and 8 cm, the area of the triangle is:
⇒ area of triangle = 1/2 x 6 x 8 = 24 cm²
If the volume of the prism is 864 cm³:
⇒ 864 = 24 x height of prism
⇒ height = 864 ÷ 24 = 36 cm

Answer:
C
Step-by-step explanation:
Data Set I is multiplicative because
x y
------------
0×2 = 0
1×2 = 2
2×2 = 4
etc.
Data Set II is additive because
x y
--------------
0+2 = 2
1+2 = 3
2+2 = 4
etc.
Answer: C
Step-by-step explanation: Hi there.
To answer this question, we need to look closely at the data tables and answers.
A cannot be right. If the relationship is additive, that means that an input x is being added to a number to get a certain number y. If the relationship is multiplicative, that means an input x is being multiplied by number to get a certain number y. The relationship cannot be additive if the input is being multiplied (and vice versa) because it does not make sense.
B cannot be right. (See A for reason)
D cannot be right. (See A for reason)
C is right. It states that Data Set I is multiplicative because y is 2 times x, and the relationship for Data Set II is additive because y is two more than x. Every x value in Data Set I is being multiplied by 2 to get y (just divide y by 2 to check), and every x value in Data Set II has 2 added to it to get y (just subtract y by 2 to check). It also gets it right that Data Set I is multiplicative and Data Set II is additive.

Ralph plotted the points (-4, 3) and (-4, -3) on a coordinate grid. What is the distance, in units, between the points Ralph plotted?
Enter your numerical answer in the box, do not include words or spaces.
Answer:
6 units
Step-by-step explanation:
Given the following question:
Point A = (-4, 3) = (x, y)
Point B = (-4, -3) = (x, y)
To find the distance between the following points we must first plot the points on the coordinate plane.
Point A: Move over to the left four times, move up three times.
Point B: Move over to the left four times, move down three times.
The distance between the two points given is "six units." Since the x values are the same, and the y values are opposites from each other doubling their distance by two.
Hope this helps.
