Answer:
1 2/7
Step-by-step explanation:
Hi! so this is very easy to solve. Let me guide you through it!
6/7 divided by 2/3
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
6/7 X 3/2
For fraction multiplication, multiply the numerators and then multiply the denominators to get
6 x 3 18
__ ___ = ____
7 x2 24
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 14 using
GCF(18,14) = 2
18 ÷ 2 9
___ ___ = ___
14 ÷ 2 7
The fraction
9/7
is the same as
9÷7
Convert to a mixed number using
long division for 9 ÷ 7 = 1R2, so
9/7=1 2/7
so there fore =
6/7÷2/3=1 2/7
(sorrry this took long i was solving it!)
40:260 is the ratio for this problem
Answer:
Option B.
Step-by-step explanation:
In a regression of y in x, the proportion oh the variation in y explained by the variable x is shown in the R-squared value. So, for answering this question we need to look at the R-squared of such regression.
In this case the R-squared is 98.9% (or 0.989), so we will the option that matches this value. Looking at your options, the one that matches the R-squared is option B.
So, B is the correct option.
