Find the slope of the line that contains the points named.
k(c + d, c - d), l(c - d, c + d)
a. -1
b. 1
c. 0

Option A is correct .i.e., Slope is -1.

Step-by-step explanation:

Given points are K(c+d , c-d) & L(c-d , c+d)

Therefore, Option A is correct .i.e., Slope is -1.

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;

answer: a) 56% women

b)44% men
