The results of a survey asking 500 people about their favorite ice cream flavor are shown in the table.
Find the experimental probability of each outcome in the sample space. Enter your answers in the boxes.
Flavor Number of People
Chocolate 90
Vanilla 125
Strawberry 60
Mint Chip 50
Other 175
P(chocolate) =
%
P(vanilla) =
%
P(strawberry) =
%
P(mint chip) =
%
P(other) =
%
Chocolate = 18%
Vanilla = 25%
Strawberry = 12%
Mint Chip = 10%
Other = 35%
The explanation for me getting these exact percentages is because of the formulas given for calculating the percentages from specific numbers and real world problems like this. When you are trying to find the calculation precentages of these types of questions, you divide the number by the total surveyed and multiple by 100.
Example:
125 / 500 = 0.25
0.25 x 100 = 25%
So, this is also how I got the other numbers, just change the "125" to the other numbers.
The experimental probability of each outcome in the sample space are:
P(chocolate) = 18%, P(strawberry) = 12%, P(vanilla ) = 25%, P(mint chip) = 10% and P(other) = 35%
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Flavor Number of people
chocolate 90
strawberry 60
vanilla 125
mint chip 50
other 175
So, the Experimental probability are:
P(chocolate)= 90/ 500 x 100 = 18%
P(strawberry) = 60/ 500 x 100 = 12%
P(vanilla ) = 125/ 500 x 100 = 25%
P(mint chip) = 50/ 500 x 100 = 10%
P(other) = 175/ 500 x 100 = 35%

I need help plsssssssss and thank you!!!!!!
Answer:
169.56
Step-by-step explanation:
The formula for finding the volume of a cylinder is: πr²h
First step: Plug in the radius and height: π•3²•6
Second step: Plug 3.14 for π: 3.14•3²•6
Third step: Simplify the equation: 3.14•9•6
Fourth step: Multiple to get your final answer: 3.14•9=28.26•6= 169.56
Triangle abc and xyz are congruent ,/_A is one half the size of /_B,/_y is 90° ./_c and /_z each have a measure of 45°.What is the measure of /_ a?
Answer:
∠a = 45°
Step-by-step explanation:
We are told that △abc and △xyz are congruent.
Thus;
∠a = ∠x
∠b = ∠y
∠c = ∠z
We are given;
∠y = 90°
Thus, ∠b = 90°
Now,we are told that ∠a is one half the size of ∠b.
Thus; ∠a = ½ × ∠b
∠a = ½ × 90
∠a = 45°

What is the ratio of the areas of AABC to AA'B'C' ?
Help please I only have 36 minutes left
According to my official calculations of the picture above, A'B'C' is 4x larger than the triangle ABC. Which would mean that ABC' is from a dialation of 4 from the original triangle, ABC.
I can't remember how you put it into the ratio form, but I think its 1:4??????

Step-by-step explanation:
whats the slope using Rise/Run?
thanks, if you help
Answer:
the slope of the given line is m = rise / run = -1/2
Step-by-step explanation:
Going from (1, -1) to (3, -2), the 'rise' is actually a drop of 1 unit; the 'run' is +2.
Thus, the slope of the given line is m = rise / run = -1/2
Find and interpret the mean absolute deviation of the data. Round your answer to the nearest tenth, if necessary. The mean absolute deviation is . Question 2 response - correct
Required data:
_______________
| 60 | 105 | 80 | 125 |
| 140 | 95 | 65 | 170 |
----------------------------
Answer:
Mean absolute deviation = 30
Variability of the data about the mean value is 30
Step-by-step explanation:
Mean = Σx / n
n = sample size = 8
Mean = (60 + 105 + 80 + 125 + 140 + 95 + 65 + 170) = 840 / 8 = 105
Mean absolute deviation = Σ|x - mean| ÷ n
( |60-105| + |105-105| + |80-105| + |125 - 105| + |140-105| + |95-105| + |65-105| + |170-105|) / 8
(45 + 0 + 25 + 20 + 35 + 10 + 40 + 65) / 8
240 / 8
= 30
The variability of data about the central point or mean value is 30.

Answer:
Mean: 43.43
Median: 42
Step-by-step explanation:
To solve for n, I should do what to both sides of the equation? n - 8 = 13
A. Add 8 to both sides of the equation.
B. Subtract 8 from both sides of the equation.
C. Subtract 13 from both sides of the equation.
D. Add 13 to both sides of the equation.

Question: Based on the data set above for the hours per day sixth graders spend using an electronic device, what is the mean number of hours sixth graders use an electronic device?
No links, useless words, or anything like that. I will report you.
Answer:
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
1+1+1+1+2+3=9
2+4+4+5+6+6+7+8+8=50
50/9=5.55555555556
or
9/50=0.18

A number x added to a number y is equal to 100. The number y is also equal to 10 more than the number x doubled. Write and solve a linear system to find the value of x and y.
Answer: x + y=100---equation 1
y =10+ 2x-----equation 2
x=30, y=70
Step-by-step explanation:
Given that
x added to a number y is equal to 100 which means that
x + y=100
and also that
y is also equal to 10 more than the number x doubled which is
y =10+ 2x
we have the linear systems to solve the equations as
x + y=100---1
y =10+ 2x-----2
Solving
Putting the value of y =10+ 2x in equation 1
x +10+ 2x =100
10+3x=100
3x=100-10
x=90/3=30
x=30
y=10 +2x = 10+2x30 =70

The product of two positive integers us 2005. F neither integer is 1, what is the sum of the two integers?
Answer:
406
Step-by-step explanation:
Given: product of two positive integers us 2005.
Let the two positive integers be a and b
Now prime factorization of 2005 = 401×5
where both 401 and 5 are prime number and non of them is 1.
So, and b will be 401 and 5 respectively.
Therefore, sum of the two integers a+b = 401+5 = 406

Ty can jump rope at a rate of 6 jumps every 3 seconds. What is Ty's jump-roping rate in
jumos per minute? Explain your thinking.
Answer:
120 Jumps per Minute
Step-by-step explanation:
3 Seconds per jump
So we do 60 (seconds in a minute) / 3 (seconds)
We get 20, this is how many times we do the 6 jumps.
Then we simply do 6x20 to get 120 jumps per minute!
