Done the first two but i dont know how to do the mean of it
Answers
To get the mean you have to add up the total number of peas in a pod, then divide the amount you added up by how many pods there are. :)
To find mean:
1) Add up all data values to get the sum
2) Count the number of values in your data set
3) Divide the sum by the count
First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.
4 x 2 = 8
5 x 10 = 50
6 x 18 = 108
7 x 14 = 98
8 x 6 = 48
8 + 50 + 108 + 98 + 48 = 312 total number of peas
2 + 10 + 18 + 14 + 6 = 50
312 / 50 = 6.24 peas per pod
So in our example the mean number of peas in a pod is 6.24.
I hope this helps! :)
Susan opened a college savings account 4 years ago. She opened the account with an initial deposit of $3,000. Starting the next year, she deposited $1,000 on the same day each year. The account earns interest at an annual rate of 4.15% and is compounded annually. Susan hopes to have earned enough interest to pay for her first year of college tuition, which costs $7,100. What is the difference between her ending balance after 4 years and the cost of her tuition?

compute the thickness of each piece of paper. show your reasoning
Answers
Answer:
Derions answer is not correct becuase 500 x 0.015=7.5 inches. If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.
If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.

Sam has 6x + 8 dollars saved. Teresa has saved 14x + 32 dollars. Together they have $220 saved. How much money have they each saved individually?
Answers
Step-by-step explanation:
given,
dollars saved by Sam = 6x + 8
dollars saved by Teresa = 14x + 32
total money = $220
a/q
money saved by,
sam + Teresa = $220
so,
6x + 8 + 14x + 32 = 220
20x + 40 = 220
20x = 220 - 40 = 180
x = 180/20 = 9
x = 9
now,
money saved by,
Sam = 6x + 8 = 6(9) + 8 = $62
Teresa = 14x + 32 = 14(9) + 32 = $158
therefore,
money individually saved by Sam is $62 and by Teresa $158.

Answer:
Melinda saves 2 less dollars than Marcus each week.
Step-by-step explanation:
Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.
14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.
Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger block?
Answers
Answer:
I think the larger block has a scale 25 times bigger than the smaller block since 100 divided by 4 equals 25
Please tell me if I'm wrong
I hope this helps
:D
Answer:
The Scale factor is 5.
Step-by-step explanation:
Because the area has cm^2 to find the scale factor you find the number it takes to get from one area to the next and take the square root.
4X = 100
X = 100/4
X = 25 (Take the sqrt because of area)
X = sqrt(25)
X = 5
The Scale factor is 5.
What is the value of the expression when c=0 and d=-6 ?

Answer:

Step-by-step explanation:
This what you wrote:
[tex] cd - \dfrac{d^2}{4} = [/tex]
[tex] = (0)(-6) - \dfrac{(-6)^2}{4} [/tex]
[tex] = 0 - \dfrac{36}{4} [/tex]
[tex] = -\dfrac{36}{4} [/tex]
[tex] = -9 [/tex]
Maybe this is what you meant to write:
[tex] \dfrac{cd - d^2}{4} = [/tex]
[tex] = \dfrac{(0)(-6) - (-6)^2}{4} [/tex]
[tex] = \dfrac{-36}{4} [/tex]

What is 4 3/10 plus (-6.2) in decimal form
Answers
Answer:

Answers
refer to steps for answer!
Step-by-step explanation:
you just have to put the given values in place of the variable names and then simply calculate.
(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8
so, B is the right answer.
please remember the correct sequence of operations :
first are brackets.
then exponents.
then multiplications and divisions.
and then (at last) additions and subtractions.
and also please remember : multiplying a negative number with a negative number creates a positive result.
that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.
now you also know the result of -2³, right ?
as this means -2 is multiplied 3 times by itself. what does that do to the sign ?
-2 × -2 = 4 (positive).
but now we have to multiply a third time
4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).

if you have a bacteria cell that you touch at 9:00 am (so now you have one cell on you) and it multiplies every 20 mins how much will i have on me at 4:00
Answers
It doubles 3 times an hour
It doubles 21 times total starting with 1
At 4:00 you will have 1,048,576 bacteria cells.
Well, 9:00 AM to 4:00 PM would be 7 hours. 7 hours into minutes would be 420. 420 divided by 20 is 21. This means it multiplies 21 times from 9:00 to 4:00. Since it multiplies by 2, than you need to skip count with the pattern multiply by 2 and stop once you have 21 numbers.
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288, 1048576. That would be 21 numbers.

Usually, when Landon makes bird food, he mixes 9 cups of seed with 6 tablespoons of maple syrup. However, today, he is short on ingredients. Describe a recipe that would make a SMALLER batch of bird food but still taste exactly the same.
Answers
Answer:
3 cups of seeds and 2 tablespoons of maple syrup
-OR-
6 cups of seeds and 4 tablespoons of maple syrup
Step-by-step explanation:
As this is a ratio of 9:6: "for every 9 cups of seeds, there is 6 tablespoons of maple syrup"
The original ratio is 3:2 "for every 3 cups of seeds, there is 2 tablespoons of maple syrup"
Using this ratio, we can infer that 3:2 or 6:4 would be a simpler answer for this problem. If there is doubt, it would be better to use 3:2 as it is the smallest ratio.
