Find the mean and median. Which measure of center best represents the data?
Answers:
Mean = 77Median = 90The median is the better measure of center=============================================
Explanation:
Part (1) Finding the mean
Add up the values to get
80 + 90 + 10 + 75 + 90 + 95 + 99 = 539
Then divide by 7 because there are 7 values in this list
539/7 = 77
The mean is 77
--------------------------
Part (2) Finding the median
First we'll need to sort the values from smallest to largest
{80, 90, 10, 75, 90, 95, 99}
will sort to
{10, 75, 80, 90, 90, 95, 99}
The middle most value is 90 since we have three items below it {10,75,80} and three items above it {90, 95, 99}.
The median is 90
--------------------------
Part (3) Which is the better measure of center?
Nearly all of the values are clustered from 75 to 99. The value 10 is an outlier since it's far from the main cluster. There are more technical processes used to find out if 10 is actually an outlier or not, but we won't deal with that right now.
The much smaller outlier pulls on the mean to make it smaller than what it should be. The mean 77 is too small to represent what the center should be. The median is not affected by outliers, which is why it's used in applications such as home prices.
The median 90 is the better measure of center.

A runner runs 400m west then changes direction and runs 600m south, If the entire trip takes 35s, what is the average speed? Give your answer in to two decimal places.
Average Speed = Total Distance / Total Time
Total Distance = 400m + 600m = 1,000m
Total Time = 35s
Average Speed = 1,000/35 = 28.57 m/s (approx.)
Answer:Average Speed in two decimal places is 28.57 m/s (approx.)

2. Jay needs 19 quarts more paint for the outside of his barn than for the inside. If he uses 107 quarts in all, how many gallons of paint will be used to paint the inside of the barn?
3. String A is 35 centimeters long. String B is 5 times as long as String A. Both are necessary to create a decorative bottle. Find the total length of string needed for 17 identical decorative bottles. Express your answer in meters.
Answer:
Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. for Jay 10 quarts would be the answer. Step-by-step explanation: He needs x quarts for the inside painting and x + 19 quarts for the outside. These two measures add up to 2x + 19, which equals 107 (quarts) total. The last one is tring A is 35 cm long, string B is 5 times as long as string A, then string B is 35·5=175 cm long. In total both strings have length 35+175=210 cm. The total length of string needed for 17 identical decirative bottes is cm that is 35.7 m.

as a percentage?
Answer: 272%
Step-by-step explanation: To write 136/50 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .
136/50 * 100 = 2.72 * 100 = 272%
And finally we have:
136/50 as a percent equals 272%

Haleigh split 4/9 of a gallon of juice into 8 cups. How much juice was in each cup?
━━━━━━━☆☆━━━━━━━
▹ Answer
1/18 of a gallon of juice in each cup.
▹ Step-by-Step Explanation
Since we have 4/9 of a gallon of juice for 8 cups, we will divide to find the amount of juice in each cup.
[tex]\frac{4}{9} / 8[/tex]
Since this operation is division, we have to change 8 to it's reciprocal which is 1/8:
[tex]\frac{4}{9}/ \frac{1}{8} = \frac{4}{72} = \frac{1}{18}[/tex]
Our final answer will be 1/18 of a gallon of juice in each cup.
Hope this helps!

what conjecture can you make about the sum of firs 52 positive even numbers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, the available details is enough to work out a solution.
Considering the first even number: 2
In this case, n = 1
The sum of the first even term is 2.
Represent the sum as a product:
[tex]2 = 1 * 2[/tex]
Considering the first two even numbers: 2 and 4
In this case, n = 2
The sum of the first two even terms is 6
Represent the sum as a product:
[tex]6 = 2 * 3[/tex]
Considering the first three even numbers: 2, 4 and 6
In this case, n = 3
The sum of the first two even terms is 12
Represent the sum as a product:
[tex]12 = 3 * 4[/tex]
Notice the pattern from n = 1 to 3
[tex]2 = 1 * 2[/tex] --- n = 1
[tex]6 = 2 * 3[/tex] --- n = 2
[tex]12 = 3 * 4[/tex] --- n = 3
------------------------------------
It follows that, the sum when represented as a product is: [tex]n * (n + 1)[/tex]
So, the sum of the first 52 even terms would be:
[tex]52 * (52 + 1)[/tex]
Where n = 52
[tex]52 * (52 + 1) = 52 * 53[/tex]
[tex]52 * (52 + 1) = 2756[/tex]
Hence, the sum of the first 52 even terms is 52 * 53 or 2756
An investment earn 6% simple interest. What amount of principal is need to have $3000 after 5 years
Answer:
The amount of $1000 principal is needed to have $3000 after 5 years.
Step-by-step explanation:
As the interest formula is
[tex]I=Prt[/tex]
Where
P is the principler is the rate in decimalt is the time in yearsSubstituting the following values in the interest formula and solve for P
I=$3000
r = 6% = 6/100 = [tex]0.06[/tex]
t = 5
so the equation becomes
[tex]I=Prt[/tex]
[tex]3000=P\left(0.06\right)\left(5\right)[/tex]
switch both sides
[tex]P\left(0.06\right)\left(5\right)=3000[/tex]
[tex]P\left(0.3\right)=3000[/tex]
[tex]P=10000[/tex] $
Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.
David is having a cookout. Hot dogs and buns are sold based on the following quantities per package.
Item
Amount Per Package
Hot dog buns
12
Hot dogs
10
A
David thought that he would have to buy 12 packages of hot dog buns and 10 packages of hot dogs to have one bun for each hot dog.
What is the LEAST amount of each David would need to buy to have an equal number of hot dogs and buns?
David should buy 2 packages of buns and 2 packages of hot dogs,
David should buy 6 packages of buns and 5 packages of hot dogs.
с David should buy 5 packages of buns and 6 packages of hot dogs,
D David should buy 22 packages of buns and 22 packages of hot dogs
B
Answer: Choice C) David should buy 5 packages of buns and 6 packages of hot dogs.
========================================================
Explanation:
Focus on the hot dog buns for now
1 package = 12 hot dog buns
2 packages = 24 hot dog buns (multiply both sides by 2)
3 packages = 36 hot dog buns (multiply original equation by 3)
We can see that the multiples of 12 are being listed. So we have
12, 24, 36, 48, 60, 72, 84, ...
as the possible number of hot dog buns we could get if we buy 1,2,3... packages.
The possible number of hot dogs we can get are
10, 20, 30, 40, 50, 60, 70, 80, ...
which are multiples of 10. Simply add 10 to each item to get the next one.
--------------------------------
Considering these two sets
12, 24, 36, 48, 60, 72, 84, ...
10, 20, 30, 40, 50, 60, 70, 80, ...
what is the lowest common multiple? That would be 60 since it is found in both lists and it is the smallest in common.
The LCM of 12 and 10 is 60.
If he wanted 60 hot dog buns, then 60/12 = 5 packages of buns is what he needs.
If he wanted 60 hot dogs, then he needs 60/10 = 6 packages of hot dogs.
Therefore, David should buy 5 packages of buns and 6 packages of hot dogs. The answer is choice C.
--------------------------------
Side note: a different way to find the LCM is to multiply 10 and 12 to get 10*12 = 120. Then we divide by the GCF 2 getting 120/2 = 60.
