Answer:
30 inches
Step-by-step explanation:
using a^2+b^2=c^2
72^2=5184
30^2=900
5184+900=6084
√6084=78
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.

The answer would be 23/41
Answer:
<1 and <3 are corresponding angles
<8 and <4 alternate exterior angles
<2 and <3 consecutive interior angles
Step-by-step explanation:
corresponding angles: the angles in matching corners
alternate exterior angles : outside alternate corners
consecutive interior angles : inside angles on one side on the transversal
