HELP NOW Each of three friends flips a coin 36 times 36 times. Angel records tail 20 times Michael records tails 17 times Fernada records tails 23 times
a. Find the relative frequency with which each friend record "Tails"
b. Which friend has a relative frequency that is closest to the theoretical probability of flipping "tails" 36 times
Answer:
A.) 60
B.) Fernada
Step-by-step explanation:
A.) you would add up all the friends records (20 + 17 = 37, 37+ 23 = 60).
B.) you would see if anybody was close to 36 and Fernada counted 23 and they would be the closes.
Pls answer dont sweat it though u tried ur best right (its worth branliest)
Answer:
A
Step-by-step explanation:
B is 180
C looks like 30-ish
D looks like 270
so A is the only one that looks to be 45
Answer:
C
Step-by-step explanation:
45/360 covers about 1/8 of the entire degress of a circle, this means the image that corresponse with be on the smaller side.
a- this seems closer to 1/4 and would not be the best match
b- this covers half, so this is much to large to correspond
c- this is the closest eyballing it, as it looks small enough to cover 1/8th as well as be properly notated
d- this is smaller and could be correct except the notation on it shows that it is going around the outside (so 360- that angle)
I hope this helps!
Which of the following statements are true? Select all that apply.
The radius of a circle is twice its diameter.
The radius of a circle is twice its diameter.
The formula to find area of a circle is A=πr2
To find the diameter of a circle, divide its circumference by π.
The circumference of a circle is greater than its diameter.
To find the diameter of a circle, multiply the radius by 2.
The diameter can be used to find area of a circle.
Answer:
Step-by-step explanation:
By definition, all radii of a circle are congruent, since all the points on a circle are the same distance from the center, and the radii of a circle have one endpoint on the circle and one at the center. ... The length of the diameter is twice that of the radius. Therefore, all diameters of a circle are congruent, too.

Step-by-step explanation:
The table represents the linear function f(x), and the equation represents the linear function g(x).
Compare the y-intercepts and slopes of the linear functions f(x) and g(x) and choose the answer that best describes them.
x f(x)
0 1
2 9
4 17
g(x) = 3x + 1
The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).
The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).

A scientist collected data on the flight of a beetle. The data was then used to create the graph below.
Based on the graph, what was the beetle's average flight speed?
Answer:
1 meter per second, or 1m/s
Step-by-step explanation:
The average speed would be the total distance over the total time, 5/5 = 1, so the average flight speed is 1 meter per second, 1m/s
1.4 is what percent of 1.12?
1.4 is what percent of 1.12=125
Step-by-step explanation:
125
Answer:
1.4 is 125% of 1.12
Step-by-step explanation:
1. We assume, that the number 1.12 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 1.12, so we can write it down as 100%=1.12.
4. We know, that x% equals 1.4 of the output value, so we can write it down as x%=1.4.
5. Now we have two simple equations:
1) 100%=1.12
2) x%=1.4
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=1.12/1.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 1.4 is what percent of 1.12
100%/x%=1.12/1.4
(100/x)*x=(1.12/1.4)*x - we multiply both sides of the equation by x
100=0.8*x - we divide both sides of the equation by (0.8) to get x
100/0.8=x
125=x
x=125
now we have:
1.4 is 125% of 1.12

A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?
Answer:
n=90
Step-by-step explanation:
As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one
so volume = length * width * height
volume of larger prism
vp=45/4 ft^3 =11.25
volume of small cubes
vs=1/2*1/2*1/2
vs=0.125 ft^3
now numbers of cube that can fit
n=vp/vs
n= 11.25/.125
n=90
so 90 smaller cubes will completely fill in the prism
Answer:
11.25 [tex]ft^3[/tex]
Step-by-step explanation:
2.5 x 3 x 1.5 = 11.25 [tex]ft^3[/tex]

Mr. Burns built a wooden platform for the Drama Club at the school where he teaches. The shape below represents the dimensions of this wooden platform. (picture is not to scale) What is the surface area, in square feet, of this wooden platform?
Answer:
108 square feet
Step-by-step explanation:
First you want to break up the "L" into two parts. These parts can be seens as a and b. You need to find out the length on the left hand side, and half of it is 6ft as seen, so if half of it is 6ft, then you need to find the other half, which is obviously 6ft. 6+6=12, and to find the area of the thinner rectangle, multiply 2*24=48. That would be the area of section a. Section b is the bottom section and what you want to do is multiply 10*6 because this is how you would find the area of section b, which would be 60. 60+48=108. I know I was not very descriptive but I still hope this somewhat helps. I also might be wrong because of the fact that it says surface area despite the fact that this shape is 2D.
The surface area, in square feet, of this wooden platform is 84 ft².
What is Surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.
We have L figured shape which can break as two rectangle.
So, the Area of rectangle 1:
= l w
= 6 x 2
= 12 square feet
and, Area of rectangle 2:
= l w
= 12 x6
= 72 square feet
Thus, the surface area of figure
= 12 + 72
= 84 square feet

Answer:
C: y= 1/50x + 4
Step-by-step explanation:
Since margo drove 200 miles to her aunts house and was left with 8 gallons of gas in the tank of her car when she arrived, we just plug the variables we know in the equation to get the answer. she drove 200 miles, so x=200. 1/50x is 1/50 times 200 aka 4. So now we just add the 4 at the end of the equation and 4 + 4 is 8. This is true, we know she had 8 gallons of gas left when she arrived and she drove 200 miles. So C is the correct answer.

The diameter of a bicycle wheel is 16 inches. How many revolutions will it take the wheel to travel about 192 inches?
a.8
b.4
c.1
d.16
Answer:
its actuly 12
Step-by-step explanation:
16x12=192
The number of revolutions it takes the wheel to travel about 192 inches is 4. Therefore, option B is the correct answer.
What is circumference of a circle?The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.
Given that, the diameter of a bicycle wheel is 16 inches.
We know that, the radius of a circle is diameter/2
Here, radius of bicycle wheel =16/2 =8 inches
As we know, the circumference of a circle is 2πr
Now, circumference of bicycle wheel is
2×3.14×8
= 50.24 feet
The wheel to travel about 192 inches
Number of revolutions =192/50.24
= 3.82
≈ 4
The number of revolutions are 4. Therefore, option B is the correct answer.

Answer:
The model that correctly shows the problem 0.4 divided by 0.2 is option 3.
Step-by-step explanation:
Option 3 has 4 out of 10 rowS shaded in, which you can infer immediately is the correct answer. Since 10 rows represent 1 whole, that means that 4 rows shaded in are 0.4. In option 3, the four rows are split by blue lines and have 2 rows, or 0.2, in each group, so option 3 matches the problem 0.4 divided by 0.2.
