If point P is 4/7 of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?

Ket [755]

Answer:

4:3

Step-by-step explanation:

Given that P divides segment MN into 4/7, let MN to be x units in length then

MP = 4/7 x =4x/7 --------(i)

But MN =MP+PN so;

x=4x/7 +PN

x- 4X/7 =PN

3x/7 =PN ----------(ii)

To get the ratio of MP:PN

MP: PN

4x/7:3x/7

MP/PN = 4x/7 / 3x/7

MP/PN =4/3

MP:PN = 4:3

A car-rental company is interested in the amount of time its vehicles are out of operation for repair work. State all assumptio

AlladinOne [14]

Answer:

13.57 < µ < 15.43

Step-by-step explanation:

Assume: We have to assume the sample comes from a normally distributed population because we do not know the population standard deviation.

We assume that it was a random sample.

Do not assume: The sample size is at least 30 because we are that it's 10. Don't assume the variance is less than the mean because we can calculate it and will know for sure.

To find a 90% confidence interval we need to find the sample mean and sample standard deviation. See attached photo 1 for the calculations

See attached photo 2 for the construction of the confidence interval
