First compute the mean:
(4.67 + 4.98 + 4.34) / 3 = 4.66
then compute the variance:
(4.67-4.66)^2 = 0.0001
(4.98-4.66)^2 = 0.1024
(4.34-4.66)^2 = 0.1024
sum of the three = 0.2049
then take the square root:
= 0.452
the standard deviation is 0.452
Answer:
answer:
it should be 14 people like apples.
step-by-step explanation:
divided 70 orange eaters by 5. 4 people only eat apples since ten eat both apples and oranges. the question also how many don't like either as well. since 74 people like these fruit there are 6 people left who don't like any of these fruits. i cant do the venn diagram though.

Answer:
x = 20
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, sum to 180°
5x + 4x = 180
9x = 180 ( divide both sides by 9 )
x = 20
Answer:
-2
Step-by-step explanation:
so plug in x into the function h(x) to get h(x)
h(x) means x in terms of h, you can also think of this as "y"
so at x = -1, y = -2
so,
h(-1) = -2
