What is EF?
a)29
b)61
c)59
d)39

EF is 61 units.

Step-by-step explanation:

EF is 61 units as we can assume that line EG intersects line FH in half, if we know that, then we can find out that EF is 61.

b) 61

Step-by-step explanation:

Triangles FEG and HEG are congruent by HL.

That makes sides EF and EH congruent by CPCTC.

b) 61

y -5 = (-1/4)(x + 8)

step-by-step explanation:

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;
