The answer is B] 3
Your answer should be 86.68.
Mean: you add up all the numbers and divide it by the total of the numbers, in this case there are a total of 11. I added all of them up and got 953.5 and divided by 11. Hoped i helped
Answer:
2.50*10 350+d
Step-by-step explanation:
- thats the answer up below
Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.
<h3>Variation</h3>
y = k × x
where,
k = constant of proportionality
y = -40
x = -5
y = k × x
-40 = k × -5
-40 = -5k
k = -40/-5
k = 8
when,
y = 8 and x = 2.5
y = k × x
8 = k × 2.5
8 = 2.5k
k = 8/2.5
k = 3.2
when,
y = 5 and x = 4
y = k × x
5 = k × 4
5 = 4k
k = 5/4
k = 1.25
