yes it is correct
with parentheses you have to bring EVERYTHING INSIDE THE PARENTHESES to the given power but not if there are no parentheses
Answer:
Statistical Questions: 1 and 3
NOT Statistical Questions: 2 and 4
Step-by-step explanation:
A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer.
For example, "How many minutes do 6th grade students typically spend on homework each week?" is a statistical question.
Answer: x = 3
Step-by-step explanation
This is a simultaneous equation. So to find x , we solve to ascertained the coordinate or point of intersection of the too lines.
y = 4x + 2, and 6x - y = 4
To solve , we need to rearrange first
y = 4x + 2 will be
4x - y = -2 -------------------------1
Equation 2 is in order
6x - y = 4 -------------------------- 2
Now solve the two equation for x by using any methods you are familiar with.
4x - y = -2
6x - y = 4, now subtract equation 2 from 1 in order to eliminate y,
we now have
-2x = -6, now divide through by 2
x = 3.
Hence y could be find by substitution for x in any of the equation above and now check.
4x - y = -2
4(3) - y = -2
12 - y = = -2
y = 12 + 2
y = 14.
Now let check
6x - y = 4
6(3) - 14
18 - 14
= 4.
Therefore, the value of x is 3

Step-by-step explanation:
The percentage would be 75% that carpenters that showed up for work
because when dividing 200 x 4 you will get 50 and 50 would equal to 25% of the total of carpenters and if you multiply 50 by 3 would get 150 and a percentage wise that would be 25% times three which is 75 and that’s how you get the answer
