Which statement below is always true? A. Two parallel lines intersect at a right angle.
B. Two parallel lines lie in the same plane.
C. Two lines that are skew to each other intersect at one point.
D. A transversal never intersects another line.

b

Step-by-step explanation:

B

Step-by-step explanation:

Parallel lines never intersect

Lines that are skew don't have to intersect

Transversal lines intersect other lines

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
