Answer: D
Step-by-step explanation: I took the test
Answer:
x = 3
Step-by-step explanation:
Add 1 on both sides.
We get:
-2x = -6
Now divide -6 by -2...
-6/-2 = 3
The answer is what that guys said
(Also what grade is this?)
Answer: Choice E) bimodal skewed
The majority of the data is towards the left side. The right outliers are skewing the mean to be pulled larger than it should be. This is why median < mean, so it's better to use the median as the measure of center. There are 2 modes here. They are the values 4 and 8 since we have these values occur the most (4 times each). That's where the term "bimodal" comes in.
42 and 14
explanation:
x+y = 56
x = 3y
Substitute for x in the first equation:
x + y = 56
x = 3y
3y + y = 56
Combine like terms:
4y = 56
Divide both sides by 4:
y = 14
So if y = 14, and x = 3y, then x = 42.
Now substitute for both x and y in both of the original equations to prove they are the correct values.
x + y = 56
x = 42
y = 4
42 + 14 = 56
56 = 56
x = 3y
x = 42
y = 14
42 = 3*14
42 = 42
So the two numbers, x and y, are 42 and 14.
