Answer:
Check the explanation
Step-by-step explanation:
Slope of the regression equation is
and intercept of the equation will be
So the regression equation will be
y'=28818.00-1439.01x
C.
the attached images below comprise of the output of the regression analysis generated by excel:
Intercept:
Hypotheses are:
t-value of intercept is 8.820
P-value is 0.0000
Since p-value is less than 0.05 so intercept is significant to the model.
Slope:
Hypotheses are:
t-value of intercept is -7.12
P-value is 0.0000
Since p-value is less than 0.05 so slope is significant to the model.
D.
Since from regression output R-square is 0.864 so 86.4% of the variation in the prices of the bicycles is accounted for by the weight of bicycles.
E.
For X= 15 estimated y value is
y'=28818.00-1439.01*15 = 7232.85
hence, required predicted price is $7232.85.
Answer:
9 3/4
Step-by-step explanation:
Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.
10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4
= 10 -1/4
= 9 3/4
__
Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.
10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)
= 10 3/4 -1
= 9 3/4
_____
We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.
Answer:
4.8
Step-by-step explanation:
Radius is 1/2 of the diameter so just do 2.4 and multiply it by 2
hope this helps :)
Answer:
15
Step-by-step explanation:
Both triangles are congruent, so RS and JI have a 1:5 ratio.
3 x 5 = 15 for HI
C)-2/3is the answer because when your have 2/3+-2/3 will equal 0 in which justifies the additive inverse
