Ik people are still answering this but if you could plz put your problem horizontally it helps us a lot and it helps you by making the problem easier to read more people are willing to do it
If you’re looking for equivalent expressions then there’s this:
5(2+3) = 5*5
5(2+3) = 10+15
If you’re looking for the answers, it’s 25. This is because 5*2=10 and 5*3=15. 10+15 is 25. Or you could add 3 and 2 (which is 5). Then 5*5= 25.
Hope this helped :)
Answer:
64
Step-by-step explanation:
Given that an advisor to the mayor of a large city wants to estimate, within 3 minutes, the mean travel time to work for all employees who work within the city limits.
Let X be the random variable denoting the time for employees to travel within city limit
Std dev of X 
For 95% confidence interval Z critical 1.96 is used because population std dev is known
Margin of error 
i.e. 
where n is the desired sample size.
Simplify to get

Hence atleast 64 employees should he poll
Answer:
5. y = 2/3x + 1
8. y = 4/7x - 4
Step-by-step explanation:
5. (-6, -3) and (6, 5)
You can use the slope formula which is (y2-y1)/(x2-x1) to find the slope and plug it back into the slope-intercept form to find the y-intercept
(5-(-3)) / (6-(-6)) = 8 / 12 = 2/3
slope-intercept form: y=mx+b where m is the slope and b is the y-intercept
to find b you can plug in one of the coordinates and the slope
5 = 6(2/3) + b
5 = 4 + b
1 = b
y = 2/3x + 1
8. (-7, -8), (21, 8)
m = (8 - (-8)) / (21 - (-7)) = 16 / 28 = 4/7
plug in one of the coordinates and the slope to find b or the y-intercept
8 = 21(4/7) + b
8 = 12 + b
-4 = b
y = 4/7x - 4
