Answer:
C, 3 1/2, 3 19/20, 3 39/40
Step-by-step explanation:
to make this a bit easier, we can put the mixed numbers into improper fractions:
3 39/40 becomes 159/40
3 19/20 becomes 79/20
3 1/2 becomes 7/2
comparing them to each other, we see they have unlike denominators. we need to get the denominators alike so we can compare them easier
the fractions all have a common denominator of 40, so we need to multiply each fraction by a number that gives us a denominator of 40
159/40 is already fine
79/20 needs to be multiplied by 2 to get a denominator of 40
79/20 x 2 = 158/40
7/2 needs to be multiplied by 20 to get a denominator of 40
7/2 x 20 = 140/40
from least to greatest, we have the following:
140/40, 158/40, 159/40
in their original form this would be:
3 1/2, 3 19/20, 3 39/40
the answer would be C
Answer:
1.509909034 x10 ^36
Step-by-step explanation:
10 plus 18 is 28
Then you would multiply 28 by 25 numbers of itself.
If x is the first integer, then x+1 is the second. x(x+1)=132 or x^2+x-132=0. This factors as (x-11)(x+12)=0. Thus either x=11 or x=-12
<span>So either 11 and 12 or -12 and -11 will do.</span>
Answer: 18.75 for each girl
Step-by-step explanation:
First you take the unit rate 2.50 multiply by 5.
2.50 x 5 = 12.50
12.50 x 3 = 37.50
37.50 / 2 = 18.75
Answer:
c. there is a positive correlation in-between x and y
Step-by-step explanation:
A regression line is a line that suggests that all the points in a scatter diagram lie on or near one particular line. In a simple regression analysis in which y is the dependent variable and x is the independent variable. If the slope is positive, the bivariate data is also said to have a positive correlation. The positive correlation in-between two variables x and y implies that in general, an increase in x goes hand in hand with an increase in y.
