The ratio of green bars to red bars is 44:33 which simplified is 4:3.
We can set up an equation to find number of red bars:
Since the ratio stays the same, # of green bars / # of red bars = 4/3,
so 200200/x = 4/3 where x = # of red bars.
Now solve for x:
200200/x = 4/3
(cross multiply)
200200*3 = 4*x
600600 = 4x
600600/4 = x
x = 150150
There 150150 red bars if there are 200200 green bars.
Hope this answers your question!

Answer:
Step-by-step explanation:
Hello!
The mean is a measurement of central tendency that shows what is the most expected value of the variable. The standard deviation is a measurement of variability, it shows you how distant or dispersed are the values of a certain population or sample in regards to the value of the mean.
In this example the variable is X: score obtained on a math test.
It's mean is μ= 52 and its standard deviation is σ= 10
To know how many standard deviations away is a value of X concerning the mean you have to first subtract the mean to the value of X, X - μ, and then you have to divide it by σ:
(X - μ)/ σ
If X=76
(76 - 52)/ 10= 2.4
The score obtained by Andrea is 2.4σ away from the mean.
I hope it helps!
8y-3=6y+17
add 3 on both sides
8y=6y+20
-6y on both sides
2y=20
divide by 2 on both sides
y=10
Answer:
50 lbs
Step-by-step explanation:
UPS: 8 + .20p
FedEx: 3 + .30p
8 + .20p = 3 + .30p
8 = 3 + .10p
5 = .10p
p = 50
