Answer:
A =112 in^2
Step-by-step explanation:
The area of a parallelogram is found by
A = bh where b is the base length and h is the height
A = 14*8
A =112 in^2
Answer:
C. 17/20, rational
Step-by-step explanation:
.25 + 3/5
The least common denominator is 20 so
.25=1/4=5/20
3/5=12/20; therefore,
5/20 + 12/20=17/20.
17/20 is a fraction so is rational.
Answer:

Step-by-step explanation:
are concyclic
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
