Answer:
45.24%
Step-by-step explanation:
Given that:
Correlation Coefficient (r) between number of hours a child play video games and number of minutes spent doing homework = - 0.74
The Coefficient of determination (r²) gives the percentage of variation in the dependent variable which can be explained by the independent variable.
Hence, the r² value = (-0.74)² = 0.5476 ; 54.76% which is about 55% variation in the number of minutes spent doing homework can be explained by the number of hours a child plays video games.
Hence the unexplained variance due to differences in children's ages is (100% - 54.76%) = 45.24%
Answer:
9.5 in
Step-by-step explanation:
The receiver is placed at the focus of the parabola at a distance of 1/4a from the vertex. Here that would be 1/(4*(1/38)) or 38/4 inches or 9.5 in
For 1)
for 2)
then change the y= part to f(x) =
Answer:
A and D
Step-by-step explanation:
It should be Sx2 + 2(S+ 1/2)
Which is equal to 4s+1
and 2(2s + 1/2) is equal to 4s+1 as well
