Answer:
Rhombus
Step-by-step explanation:
It does not have congruent diagonals
Answer:
0 and 4
Step-by-step explanation:
Since the shape is a quadrilateral, the interior angles add to 360 degrees. Thus, angle C is 360 - 82 - 92 - 102 = 84 degrees.
Answer:
32 days must be sampled to test the proposed hypothesis.
Step-by-step explanation:
Consider the provided information.
The average number of person-hours per day spent on these task was
.
The actual value of μ is 12 hours or less i.e μ=12
She wants a test having α=0.05
The probability of a type II error of at most β=0.10 and σ=7.64.
δ = μ-μ0
= 12-16
= -4
Now use the formula for calculating the sample size:

Substitute the respective values.



Hence, 32 days must be sampled to test the proposed hypothesis.
1) 2 minutes = 2 x 60 = 120 seconds
2) 1500 meters per second x 120 seconds = 180 000 meters = 180 km
