Answer:
x<-5
Step-by-step explanation:
-0.4x>0.8+1.2
-0.4x>2
x<-5
Answer:
True
Step-by-step explanation:
Considering the above definition of Pooled Variance, the correct answer is TRUE.
This is because Pooled variance is used to determine the reasonable estimates of variance, where several repeated tests are expected at each value.
This helps to provide greater precision estimates of variance.
It is taller by 7 ft and 3 inches
You can first convert both values to inches and then subtract. Finally convert them back to ft and inches
C = (5,4)
D = (4,2)
Dilation with factor 8 => for the same x, y increase by a factor of 8
=> C' = (5, 8*4) = (5, 32)
=> D' = (4, 8*2) = (4, 16)
slope of C'D' = [32 - 16] / [5 -4 ] =16
You can also see that the slope of CD = [4 - 2] / [5 - 4] = 2
Then, the new slope is 8 times the old slope, this is it was multiplied by the same factor, 8.
Answer: 16
In this question, you are only able to cancel out the (x + 5). The others are unable to be cancelled.
