A = b * h
b = 8 2/3
h = 5 3/4
A = 8 2/3 * 5 3/4.....turn to improper fractions
A = 26/3 * 23/4
A = 598/12
A = 49 5/6 ft^2 <====
=3/2+ 9/4+ 2/2
=1.5+ 2.25+ 1
=4.75
Answer:
the area is 30
Step-by-step explanation:
area of triangle =base×height
so ,
base=7.5
height=4
why , shouldn't we take 5(or)6 as height because we shouldn't take slanting lengths as height.
so apply base and height in the formula
7.5×4=30

Answer:
The lower bound for a 90% confidence interval is 0.2033.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The lower bound for a 90% confidence interval is 0.2033.
