Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values

pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Proof that the formula Fn = Fn-1 + Fn-2 works
Fibonacci python
Answers
IV. The sum of the first n Fibonacci numbers with even indices is
f2 + f4 + ... + f2n = f2n+1 - 1.
Proof:
From II,
f1 + f2 + f3 + ... + f2n = f2n+2 - 1.
When we subtract the result from III, we get the desired result.
Example:
f2 + f4 + f6 + f8 + f10 + f12 = 1 +3 + 8 + 21 +55 +144
= 232
= f13 - 1 .
V. The sum of all (fn+1)/ (fn )
converges to the Golden Ratio.
3/1 + 5/3 + 8/5 + 13/8 .... converges to ) / 2.
Proof that Rn converges to the Golden Ratio:
Let R = lim Rn as n approaches infinity
= lim f n+1 / f n as n approaches infinity
= lim fn + fn-1 /fn as n approaches infinity
= lim (1 + fn-1/ fn) as n approaches infinity
= 1 + lim (fn-1 /fn ) as n approaches infinity
= 1 + 1/ lim (fn-1 /fn ) as n approaches infinity
= 1 + 1/R
So, R = 1 + 1/R,
or R^2 = R + 1,
R^2 - R - 1 = 0,
R = ( ) / 2
= ( ) / 2
Since Rn is positive, Rn = ( ) / 2 .
Thus, Rn converges to the Golden Ratio.

The estimated number of people attending the fair this year is 14,646. The approximate number of people receiving prizes is 976.
Step-by-step explanation:
To estimate this year's attendance, I calculated the difference in attendance for each year. 1,176 more people attended in year 2 than in year 1; 1,763 more people attended in year 3 compared to year 2; and 1,087 more people attended in year 4. Totaling to 4,026 more people attending in year 4 than in year 1. From there, I found the average rate of change by dividing 4,026 by 3 to get 1,342. So, on average, 1,342 more people attend the county fair each year. Add that to 13,304, and we get 14,646.
20% of 14,646 is the equivalent of 14,646 ÷ 5. 14,646 ÷ 5= 2,929.2. I rounded this to 2,929. So, 2,929 people will receive raffle tickets.
2,929 ÷ 3= 976 \(\frac{1}{3}\). We round this to 976. So, we can guess that 976 people who attend the county fair will receive a small gift.

Answer:
1: 7.5 2: 25 3: 14.2
Step-by-step explanation:
For all of these, you want to use the Pythagorean Theorem, which is a^2+b^2=c^2
1. you would have to plug in 13 for b, and 15 for c, because 15 is the hypotenuse
a^2+13^2=15^2
now, solve for a
a^2+169=225
225-169=56
a^2=56
to undo a squared, you have to take the square root of both sides
sqrt(56) is about 7.5
to check, you would have to plug in 7.5 for a
2. you would start off the same way, but this time we are solving for c
15^2+20^2=c^2
225+400=c^2
625=c^2
take the square root of 625
25 is your answer
if you want to check, plug in 25 for c
3. we are trying to find the hypotenuse again, so we are solving for c
5.1^2+13.2^2=c^2
26.01+174.24=200.25
200.25=c^2
take the square root once again
it is approximately 14.2
if you want to check, plug in 14.2 for c
have a great day!

During a 20% off sale, the sale price of a microwave was $60. The sale has expired but Kristen has a coupon good for 15% off the regular price of any one item. How much will Kristen pay for the microwave before tax? Round to the nearest cent.
Answers
Answer:
it would take 9 dollar OFF!! so subtracted by 60 your welcome!!
(its 51 just saying.)
Step-by-step explanation:
x - 0.2x = 60
Simplifying the left side, we get:
0.8x = 60
Dividing both sides by 0.8, we get:
x = 75
So the regular price of the microwave is $75. Now, we can use Kristen's coupon to find the price she will pay:
Regular price = $75
Discount from coupon = 15%
Amount of discount = 0.15 x $75 = $11.25
Subtracting the discount from the regular price, we get:
Price after coupon = $75 - $11.25 = $63.75
Therefore, Kristen will pay $63.75 for the microwave before tax.

What is the height of a cylinder with a radius of 3 and a volume of 189?
Answers
Answer:
6.68 units (2 d.p.)
Step-by-step explanation:
The formula for the volume of a cylinder is:
\(\boxed{V=\pi r^2 h}\)
where:
V is the volume.r is the radius of the circular base.h is the height.Given values:
V = 189 cubic unitsr = 3 unitsTo find the height of the cylinder, substitute the given values into the formula and solve for h:
\(\implies 189=\pi \cdot 3^2 \cdot h\)
\(\implies 189=9\pi \cdot h\)
\(\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}\)
\(\implies \dfrac{189}{9 \pi}=h\)
\(\implies h=6.6845076...\)
Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).
Answer:
h≈6.68
Step-by-step explanation:
6.68 is the height of a cylinder with a radius of 3 and a volume of 189
