Which equation models the problem?
Olayinka is participating in a bowl-o-thon to benefit the local hospital. Each sponsor will pay Olayinka $2 plus $0.10 per pin, x, that
she knocks down. How much will Olayinka raise per sponsor, B, for knocking down 52 pins?
OB-(2-0.10)
OB=0.10x + 2
O
B - (0.10 + 2)x
OB = 2x + 0.10

were is the equation

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;

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

answer: c
