Step-by-step explanation:
b is the correct answer.
Answer:
if you meant x times y...
15 x 20 is 300.
if you meant x + y...
15 + 20 is 35.
if you meant anything else, please let me know
the way it was written confused me but I tried.
Answer:
129
Step-by-step explanation:
Considering the survey to be representative, you can simply multiply the share of students <em>p</em> preferring “Track & Field” with the whole school population at the same time to estimate the number of such students in the whole school.
First we need to find the relative share <em>p</em> of such answers in the study by dividing it by the sum of answers, assuming that the table is complete for that random sample:
<em>p</em> = 4/(8 + 5 + 4) = 4/17
Then for the whole school we get 550 <em>p</em> ≈ 129.4
A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)
To find equivalent equations, you simply have to simplify both of these :)
a) 5/6(x - 6) + 1/6(3 - x)
Simplify.
5/6x - 5 + 1/2 - 1/6x
Add like terms.
(5/6x - 1/6x) + (-5 + 1/2)
Simplify.
4/6x +(-4.5)
Simplify.
2/3x - 4.5
b) (y + 7)4 + 8 - 5y
Simplify.
4y + 28 + 8 - 5y
Add like terms.
(4y - 5y) + (28 + 8)
Simplify.
-y + 36
~Hope I helped!~
