Cerrena [4.2K]

Answer:

28 hours

Identify the equation of the line perpendicular to 9x - 3y = 18.
sweet [91]

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The exemplar equation has slope

9x - 3y = 18

    - 3y = -9x + 18

        y = 3x - 6

m = 3

so perpendicular slope will be -1/3

D has such a slope

3y = -x + 1

 y = (-1/3)x + 1/3

PLEASE HELP ME SOLVE this
Alisiya [41]

Answer:

y=-12/11

Step-by-step explanation:

y-(-12/11)=0(x-(-12/13))

y+12/11=0(x+12/13)

y+12/11=0

y=-12/11

Since the slope equals 0, then the line is horizontal.

The heights in inches of orangutans Are normally distributed with a population standard deviation of 3" and an unknown populatio
CaHeK987 [17]

Answer: The 95% confidence interval is approximately (55.57, 58.43)

======================================================

Explanation:

At 95% confidence, the z critical value is about z = 1.960 which you find using a table or a calculator.

The sample size is n = 17

The sample mean is xbar = 57

The population standard deviation is sigma = 3

The lower bound of the confidence interval is

L = xbar - z*sigma/sqrt(n)

L = 57 - 1.960*3/sqrt(17)

L = 55.5738905247863

L = 55.57

The upper bound is

U = xbar + z*sigma/sqrt(n)

U = 57 + 1.960*3/sqrt(17)

U = 58.4261094752137

U = 58.43

Therefore the confidence interval (L, U) turns into (55.57, 58.43) which is approximate.
