125
375
Answer:
Mean: 95, Median: 50 Mode: 25
Step-by-step explanation:
1.Mean: add all the numbers then divide by the number of numbers there
25+25+25+25+50+50+125+125+125+375= 950
950 divided by 10 = 95
2.Median :is the number in the middle of all the numbers in this case we have 2 so we will ad those two then divide them by two
50+50=100 100/2 = 50.
3. Mode : this is the most recurring number there and in this case it's 25
A brick layer can build a wall in 6 hours and his apprentice would need 16 hours to build the same wall. When they work together, the apprentice works 5 hours longer than the brick layer. How many hours does each work
Answer:
Step-by-step explanation:
The brick layer builds ( 1 wall ) / ( 6 hrs )
That's the same as ( 1/6 wall ) / ( 1 hour )
------------------------------------
The apprentice builds ( 1 wall ) / ( 16 hrs )
That's the same as ( 1/16 wall ) / ( 1 hour )
--------------------------------------
Let t = the time that the brick layer works
t + 5 = the timer the apprentice works
-----------------------------------------
( brick layer's rate ) x ( brick layer's time ) +
( apprentice's rate ) x ( apprentice's time ) = 1
( 1 is the whole job )
-----------------------------------------
(1/6) · t + (1/16) · (t + 5) = 1
Multiply both sides by 48
8t + 3t + 15 = 48
11t = 33
t = 3
t + 5 = 8
the brick layer works 3 hrs
The apprentice works 8 hrs
----------------------------
Check:
(1/6) · t + (1/16) · (t + 5) = 1
(1/6) · 3 + (1/16) · (3 + 5) = 1
1/2 + 1/2 = 1

An elementary class consists of 8 boys and 10 girls. A child is chosen at random and it is a girl. A second child is randomly chosen again from the remaining children, and it is a boy. Was the probability of choosing the boy dependent on choosing a girl first
Answer:
Yes
Step-by-step explanation:
So we know the second child was a boy however if the first child was a boy, the probability of getting a second boy would be 7/17 since one boy is missing and one person is missing from the total.
However, if a girl was chosen as the first child, the probability of getting a boy second would be 8/17 since no boys would be missing but one person would be missing from the original total.

The area of a circle is 60.12cm find the length of the radius rounded to 2 dp.
Answer:
Before you write the answer to your question, make sure the question is asking for the actual value of pi or 3.14.
If the question was asking for the question to be completed with the ACTUAL VALUE of pi, then your answer is ----> 4.37
If the question was asking for the question to be completed with the rounded of pi (3.14), then your answer is ----> 4.38
It's a subtle difference, but remember, there is no such thing as close in math, it's either right or wrong.
Step-by-step explanation:
Given: Circle's Area, 60.12
As the value of pi was not directly stated, I will divide the answer into 2 portions, portion one with the answer with the actual infinite value of pi, and one where I will describe how to do it with 3.14 as pi.
Explanation with 3.14:
First thing first, know the formula for calculating the area of a circle:
[tex]A = \pi r^2[/tex]
[tex]A[/tex] stands for Area, and [tex]r[/tex] stands for Radius
Now, plug in the given values:
[tex]60.12 = \pi r^2[/tex]
Next, replace 3.14 for pi:
[tex]60.12 = (3.14)r^2[/tex]
Then, divide both sides by 3.14 ,which gives us:
[tex]19.15 = r^2[/tex]
Please note: 19.15 is rounded
Anyway, to isolate [tex]r[/tex], we take the square root of both sides:
[tex]\sqrt{19.15} = \sqrt{x^2}[/tex]
The square root and square on the right side of the equation cancel out, and we are left with:
[tex]4.38 = r[/tex]
Please note that 4.38 was rounded

Answer:
Learning Objective: Use the mean and range to compare the spread and averages.
a) Sarah Mean = 70.9, Katie Mean = 78.9
b) Sarah Range = 15, Katie Range = 25
c) Sentences
- The mean shows, on average, Sarah was 8 seconds quicker than Katie.
- The range shows that Sarah was more consistent with her times. Katie had a larger spread of times which shows she was less consistent.
Step-by-step explanation:
Given:
Sarah's Data Set:
79, 70, 68, 75, 69, 64, 69, 75, 64, 76Katie's Data Set:
79, 79, 76, 81, 89, 76, 64, 85, 82, 78To Find:
The mean and range of both data sets separately.Work:
The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is [tex]\mu = \frac{{\sum}x}{N}[/tex].
The formula for the mean of a sample is [tex]\bar{x} = \frac{{\sum}x}{n}[/tex].
Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values given above, the solution is: [tex]\frac{709}{10} = 70.9[/tex]
Therefore, the mean of Sarah's data set is 70.9.
For Katie's Data Set, [tex]\frac{789}{10} = 78.9[/tex].
Therefore, the mean of Katie's data set is 78.9.
To fill in the summary, we have to use the data we just calculated.
That summary can be found in the answer section.
Answer:
Sarah's mean = 70.9
Katie's mean = 78.9
Sarah's range = 15
Katie's range = 25
The mean shows that on average Sarah was 8 seconds faster than Katie. The range shows that Sarah was more consistent with her times. Katie had a larger spread of times which shows she was less consistent.
Step-by-step explanation:
Identifying the mean time for Katie and Sarah
The mean ( average ) is equal to the sum of the numbers in the data set ( the sum of the swimming times ) divided by the number of values in the data set ( which is given as 10 )
Mean for Sarah : Sum of her swimming times : 79 + 70 + 68 + 75 + 69 + 64 + 69 + 75 + 64 + 76 = 709
Number of values = 10
So mean = 709 / 10 = 70.9 seconds.
Mean for Katie : Sum of her swimming times : 79 + 79 + 76 + 81 + 89 + 76 + 64 + 85 + 82 + 78 = 789
number of values = 10
so mean = 789 / 10 = 78.9
Using this information we can identify what the first to blanks are. The mean shows that on average Sarah was ___ seconds ____ than Katie.
The mean time for Sarah was 70.9 seconds and the mean time for Katie was 78.9 seconds. So on average Sarah was faster and by 8 seconds ( which can be found by subtracting Sarah's mean from Katie's )
Identifying the range
The range is equal to the largest value ( longest swim time ) subtracted by the smallest value ( or quickest swim time )
Range for Sarah : Sarah's highest swim time is 79 seconds and her lowest is 64 seconds.
So her range = 79 - 64 = 15 seconds
Range for Katie : Katie's highest swim time is 89 seconds and her lowest time is 64 seconds
So her range = 89 - 64 = 25
Using this information we can fill out the remaining blanks.
The range shows that ____ was more consistent with her times. ___ had a larger spread of times which shows she was ____ consistent.
The higher the range the less consistent you are vise versa. Katie had a larger range hence, Sarah was more consistent and Katie was less consistent.

mother buy 12.5 ounces of green coffee beans. What is the total cost of the green
coffee beans?
Answer:
$36.3
Step-by-step explanation:
The total cost of the Green coffee beans is $7.25.
What is Total Cost?Total cost (TC) is the minimum cost of producing some quantity of output. This is the total economic cost of production and is made up of variable cost, which varies according to the quantity of a good produced and includes inputs such as labor and raw materials, plus fixed cost.
Here, Green coffee beans cost $0.58 for each ounce.
Amina and her mother buy 12.5 ounces of green coffee beans
Total cost = cost each ounce X Number of ounces
TC = 12.5 X 0.58
TC = $ 7.25
Thus, the total cost of the Green coffee beans is $7.25.

If it takes 15 minutes to dry your hair with a 1.200 kW hair drier, how much energy is used in drying your hair?
The quantity of energy moved or transformed per unit of time is referred to as power. The amount of energy that is consumed by the hairdryer in 15 minutes will be 0.3 kWh.
What is power?The quantity of energy moved or transformed per unit of time is referred to as power.
Formula: Power = Energy / Time
Units: kW = kWh / hour
The power of electric equipment is given by the formula,
P = E/t
where E is the energy consumed in kWh and t is the time in hours.
Given the power of the hairdryer is 1.200 kW while the time for which it is kept on is 15 minutes, therefore, 0.25 hours. Now, the energy consumed by the dryer in 15 minutes will be,
1.200 kW = E / 0.25
0.3 kWh = E
