I'm not 100% sure but what I remember it's this
15% of the total candy is cherry....and there are 20 candies...
so 15% of 20 is cherry...0.15(20) = 3...so there are 3 cherry flavored in a box of 20
Answer:
40 gal / 72 gal
lets reduce
20 / 36
(yeah, the gal reduce away as well)
reduce further
10/18
and further
5/9
done :)
Answer:
a =55
b =16
c = 25
d = 9
Step-by-step explanation:
of means multiply is means equals
20% of a is 11
.20 a = 11
Divide by .20
a = 11/.20
a=55
75% of b is 12
.75 b =12
Divide by .75
b = 12/.75
b = 16
80% of c is 20
.80 c =20
Divide by .80
c = 20/.80
c =25
200% of d is 18
2.00 d = 18
Divide by 2.0
d = 18/2
d =9
It seems appropriate to use the linear regression function of your calculator for this. Looking at the data, you know the slope is generally positive, so only the 1st and 3rd choices are potentially viable.
A calculator shows the correlation coefficient (r) rounds to 0.816, so the appropriate selection is ...
A. 0.816
