C.)1/4
D.)3/4
To find the fraction just count the number of figures total. This is the denominator of your fraction
NExt just count how many spaces are shaded and that number is your numerator
For example in A we see that there is 4 triangles total
Therefore our fraction currently is x/4
NeXT we see that there are 2 shaded in
This makes our fraction 2/4 which if simplified is 1/2

Given a normal distribution with a mean of 120 and a standard deviation of 12, what percentage of values is within the interval 96 to 144
Answer:
0.9545
Step-by-step explanation:
Given that :
Mean (m) = 120
Standard deviation (s) = 12
what percentage of values is within the interval 96 to 144
P(96 < x < 144)
P(x < 96)
obtain the standardized score (Z) :
Z = (x - m) / s
Z = (96 - 120) / 12 = - 2
p(Z < - 2) = 0.02275 ( Z probability calculator)
P(x < 144)
obtain the standardized score (Z) :
Z = (x - m) / s
Z = (144 - 120) / 12 = 2
p(Z < - 2) = 0.97725 ( Z probability calculator)
p(Z < - 2) - p(Z < 2) = 0.97725 - 0.02275 = 0.9545

Step-by-step explanation:
Bouncing Baby Company sells their cribs for the following amounts to stores
Number of Cnbs
10
Price
$1320
50
S6600
Which of the following statements about the price of the cribs are true if the price remains proportional to the number of cribs Select TWO that apply.
A. 6 cribs cost $600
B. 22 anos cost $2640
C. 40 cribs cost $5280
D. 55 cribs cost $7920
E. 80 cribs cost $10.500
F. 250 cribs cost $11 880
Answer:
Option C
Step-by-step explanation:
Since, Price of cribs (P) are proportional to the proportional to the number of cribs (N) sold,
P ∝ N
P = kN
Here 'k' is the proportionality constant
To get the value of proportionality constant,
Since, value of 10 cribs is $1320
1320 = k(10)
k = 132
Therefore, equation will be
P = 132N
Option A
If number of cribs = 6
P = 132(6) = $792
False.
Option B
For N = 22
P = 132(22) = $2904
False.
Option C
For N = 40
P = 132(40) = $5280
True
Option D
For N = 55
P = 132(55) = $7260
False
Option E
For N = 80
P = 132(80)
= $10560
False
Option F
For N = 250
P = 132(250)
= $33000
False
If the given options have been written correctly only one option, Option (C) is correct.

Answer:
r=144
Step-by-step explanation:
Cross multiply:
12 * 60 = r * 5
Simplifying
12 * 60 = r * 5
Multiply 12 * 60
720 = r * 5
Reorder the terms for easier multiplication:
720 = 5r
Solving
720 = 5r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-5r' to each side of the equation.
720 + -5r = 5r + -5r
Combine like terms: 5r + -5r = 0
720 + -5r = 0
Add '-720' to each side of the equation.
720 + -720 + -5r = 0 + -720
Combine like terms: 720 + -720 = 0
0 + -5r = 0 + -720
-5r = 0 + -720
Combine like terms: 0 + -720 = -720
-5r = -720
Divide each side by '-5'.
r = 144
Simplifying
r = 144
Answer:
r=144
Step-by-step explanation:
We need to find r. To do that me must make the top numbers the same.
We'll multiply
[tex] \frac{12}{r} \times \frac{5}{5 } = \frac{60}{5r} [/tex]
[tex] \frac{5}{60} \times \frac{12}{12} = \frac{60}{720} [/tex]
Since the top numbers are equal that means the bottoms are too.
So we can create the equation:
[tex]5r = 720[/tex]
Divide each side by 5
r=144

first put the points, then just draw the line that goes throw that row of dots.
Step-by-step explanation:
so this isnt very complicated, you need to put the points on the coordinate plane (the grid) and find where they meet coordinates (written starting with the x and ending with the y are written like this: (x,y))
go to the bottom line (x axis) and find the number in the x row on the page, then take the vertical line and go until the two ends meet,repeat that until there are no more coordinates to graph on the left box draw a straight line for all of the coordinates do the same with the other box drawing a line whre the other coordinates. if done right the lines should intersect, and the intersecting point is the answer

A car travels around a circular track of radius 1.5 miles. It traversed35of a complete revolution. Howfar did it travel?
Answer:
The total distance traveled by the car is 330 miles.
Step-by-step explanation:
The circular track is the circumference of circle with radius 1.5 miles.
Circumference of a circle = 2[tex]\pi[/tex]r
Thus,
Circumference of the track = 2 x [tex]\frac{22}{7}[/tex] x 1.5
= 9.4286571429
Circumference of the track = 9.4286571429 miles
But, one complete revolution by the car is the circumference of the track.
i.e One complete revolution round the track = 9.4286571429 miles
Therefore,
35 complete revolutions round the track = 35 x 9.4286571429 miles
= 330 miles
The total distance traveled by the car is 330 miles.
Please help!! Will mark brainilest ☺️
Answer:
B
Step-by-step explanation:
Because there's no change in x so it has to be a straight line going through the y-axis.
Also for A and C, they don't even touch y = 2 so you can easily cross those out.
how can you tell whether or not a figure is a scaled copy of another figure?

a rectangular prism has a width of 0.5 a height of 4 and a length of 1.5, what is the surface area of the rectangular prism?
Answer:
The surface area of the rectangular prism is 17.5
Step-by-step explanation:
We are given:
Width of rectangular prism (w) = 0.5
Length of rectangular prism (l) = 1.5
Height of rectangular prism (h) = 4
We need to find the surface area of the rectangular prism.
The formula used is: [tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)[/tex]
Putting values and finding the surface area of the rectangular prism
[tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)\\Surface \ area \ of \ the \ rectangular \ prism=2((1.5)(0.5)+(1.5)(4)+(0.5)(4))\\Surface \ area \ of \ the \ rectangular \ prism=2(0.75+6+2)\\Surface \ area \ of \ the \ rectangular \ prism=2(8.75)\\Surface \ area \ of \ the \ rectangular \ prism=17.5[/tex]
So, the surface area of the rectangular prism is 17.5
