Point b lies on segment AC. find the length of segment BC if AB = 4mm and AC = 4cm
Nataly_w [17]

Answer:

Segment BC = 36 mm or 3.6 cm

Step by Step Explanation:

There are 10 mm in 1 cm

meaning that segment AC is 40 mm long

if AB is 4 mm and it is one part of the two, then we need to subtract that from the total to find out what is left.

40 - 4 = 36

Segment BC = 36 mm or 3.6 cm

A supervisor records the repair cost for 25 randomly selected dryers. A sample mean of $93.36 and standard deviation of $19.95 a
Feliz [49]

Answer:

The 98% confidence interval for the mean repair cost for the dryers is (83.4161, 103.3039).

Step-by-step explanation:

We have a small sample size n = 25, \bar{x} = 93.36 and s = 19.95. The confidence interval is given by  \bar{x}\pm t_{\alpha/2}(\frac{s}{\sqrt{n}}) where t_{\alpha/2} is the \alpha/2th quantile of the t distribution with n - 1 = 25 - 1 = 24 degrees of freedom. As we want the 98% confidence interval, we have that \alpha = 0.02 and the confidence interval is 93.36\pm t_{0.01}(\frac{19.95}{\sqrt{25}}) where t_{0.01} is the 1st quantile of the t distribution with 24 df, i.e., t_{0.01} = -2.4922. Then, we have 93.36\pm (-2.4922)(\frac{19.95}{\sqrt{25}}) and the 98% confidence interval is given by (83.4161, 103.3039).
