Which angle has a measure equal to the sum of the m∠sqr and the m∠qrs? ∠rsc ∠sre ∠dqs ∠qsr

The correct answer is <RSC

Step-by-step explanation:

In the triangle SQR

m<SQR  + m<QRS = m<RSQ

The linear pair of <RSQ is the correct answer

To find the linear pair of <RSQ

The linear pair of <RSQ have two same vertex and the center vertex must be S

The option consists only one such angle which is <RSC

Therefore, the correct answer is <RSC

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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;
