Answer:
Volume = 840 cm³
Step-by-step explanation:
Let's divide the whole prism into 2 rectangular prism:
<em><u>Rectangular Prism 1:</u></em>
=> Volume =
=> Volume = 8*15*6
=> Volume = 720 cm³
<u><em>Rectangular Prism 2:</em></u>
=> Volume =
=> Volume = 5*4*6
=> Volume = 120 cm³
<u><em>Whole Prism:</em></u>
=> Volume = 720+120
=> Volume = 840 cm³

Answer:
Option B:
Classification:
The hypothesis test is Two-tailed.
Step-by-step explanation:
The mean length of imprisonment for motor-vehicle theft offenders in this country is 22.1 months.
This means that the null hypothesis is that the mean is of 22.1 months, that is:
A hypothesis test is to be performed to determine whether the mean length of imprisonment for motor-vehicle theft offenders in this city differs from the national mean of 22.1 months.
At the alternate hypothesis, we test if this mean is different of 22.1, that is:
Which means that the answer is given by option b).
Which of the following is the correct classification of the hypothesis test?
We test if the mean is different from a value, which means that the hypothesis test is Two-tailed.
Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A = × 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
