Find the length of the third side. If necessary, write in simplest radical form.
V33
7

Step-by-step explanation:

pyrhagoras theorem

a^2+b^2=c^2

( )^2+b^2=7^2

33+b^2=49

b^2=49-33

b=

b=4

therefore the length of the third side is 4

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

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;
