A. 30.6%
B. 48.2%
C. 51.8%
D. 69.4%
Answer:
The answer is 48.2%
Step-by-step explanation:
The correlation coefficient r between a child age x and the number of minutes spent doing homework each day y is 0.694 i.e r=0.694
Now, we have to find percent of the variation.
The coefficient of determination is
The square of r(correlation coefficient) is the percent of variation that is explained by the dependent variable.
If r=0.694 ⇒ this means that 48.2% of variation in dependent variable.
Answer:
Doubling a number means multiplying it by 2. If there is a pattern or rule that suggests doubling is necessary, it could be based on a specific mathematical relationship or calculation.
Step-by-step explanation:
For example, if there is a consistent pattern of doubling in a mathematical sequence, it could indicate exponential growth or a specific mathematical operation being applied. In some scenarios, doubling may be necessary to account for the accumulation or growth of a value over time.
It is important to note that without the specific context or information provided on the previous page, it is difficult to give a definitive explanation for why 8 is being doubled to find Julie's money on Day 4.
Q(−2,1),R(−3,4),S(−5,3),T(−4,0)
B
Q(−2,−1),R(−3,−4),S(−5,−3),T(−4,0)
C
Q(1,2),R(4,3),S(3,5),T(0,4)
D
Q(2,−1),R(3,−4),S(5,−3),T(4,0)
Answer:
The correct answer is:
D) Q(2,1) R(3,-4) S(5,-3) T(4,0)
Step-by-step explanation:
When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.
Then the new coordinates of the parallelogram are:
Q(2,-1) R(3,-4) S(5,-3) T(-4,0)
now i am 100. what is my brothers age
A. -2
B. 0
C. -1
D. 2
The perimeter is the sum of all of the lengths of the sides. To find the perimeter, add together the length of each side.
For this triangle, our side lengths are 7, 7, and 9.
7 + 7 = 14
14 + 9 = 23
The perimeter of a triangle that has two sides measuring 7 centimeters and a third side measuring 9 centimeters is 23 centimeters.
Hope this helps!! :)
