Answer:
Option A is correct.
Step-by-step explanation:
Correlation coefficients tell us how strongly the two variables are associated.
A positive correlation is a relation when both the variables move together in the same direction. Like if value of first increases the other also increases.
When the correlation coefficient is greater than 0, this means that both variables are correlated.
So, the answer here will be :
A. There is a linear relationship between the variables, and whenever the value of one variable increases, the value of the other variable increases.
<span>16 6/9 inches < 16 16/18 inches
or
Perimeter of square clock < Perimeter of rectangular clock
First we would put convert the perimeter fractions into equivalent terms. So for the square clock, 16 6/9 inches becomes 16 12/18 inches (multiplying the fraction by 2/2). Now it is obvious that that the square clock at 16 12/18 inches has a smaller perimeter than the rectangular clock with a perimeter of 16 16/18 inches.</span>

Answer:
9<sqrt(97)<10
Step-by-step explanation:
Perfect squares:
1
4
9
16
25
36
49
64
81
100
121
144
169
....so on
97 is between 81 and 100
So square root of 97 is between sqrt(81)=9 and sqrt(100)=10.
9<sqrt(97)<10
Answer:
C.
Step-by-step explanation:
First, we calculate the amount if ammonia in 22 gallons of 16% ammonia solution.
16% * 22 gal = 3.52 gal
The amount of ammonia remains the same after the water evaporates, but the total amount of solution is reduced by the amount of water that evaporates.
amount of ammonia: 3.52 gal
amount of water that remains: 22 - n
desired concentration, 24% = 24/100
Equation:
(3.52)/(22 - n) = 24/100
Answer: C.
