PLS HELP QUICK!! For the data in the table, does y vary directly with x? If it does, write an equation for the direct
variation
XY
16 4
32 16
48 36
Oyes; y = 2x
Oyes, y = 4x
Oyes: y = 8x
Ono; y does not vary directly with x.

the answer will be the last one

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;

m∠a is 90°

m∠b is 40°
