Answer:
h = a/4
Step-by-step explanation:
h = a/4 has already been solved for h; there is nothing left to do here.
Answer:
There is no enough evidence to reject the claim using a level of significance of 5%
Step-by-step explanation:
Let p be the true proportion of homeowners in Omaha who own a lawnmower. We want to test
vs
(two-tailed alternative).
We have a large sample of size n = 500 and a point estimate for p is
. The test statistic is given by
where
is the standard error of
when
is true. The observed value is
= 1.4064 which comes from a standard normal distribution. Because we want to use a level of significance of 5%, our rejection region is RR={z | z < -1.96 or z > 1.96} where -1.96 and 1.96 are the 2.5th and 97.5th quantiles respectively. Because 1.4064 does not belong to RR, we fail to reject the null hypothesis.
Answer:
x = 75°
Step-by-step explanation:
Sum of angles in a triangle: 180°
So,
50°+55°+x=180°
105°+ x = 180°
Subtract 105° from both sides
x = 75°
Answer:
b - 8
Step-by-step explanation:
3b - 2b = b
-6 - 2 = 8
= b - 8
