Answer:
3rd one and last one
Step-by-step explanation:
First one:
4 × 3 × 4 = 48
Second one:
1 × 2 × 4 = 8
Third one:
2 × 3 × 5 = 30
Fourth one:
2 × 5 × 4 = 40
Fifth one:
2 × 2 × 4 = 16
Process of elimination:
The first one is itself greater than 47 units³, so this is definitely not one of the two;
A combination of the fourth prism and the smallest one as the second will give a volume of 48 units³, which is greater than 47 so this prism is also not one of the two we are looking for;
This leaves the second, third and fifth;
The second and third sum to 38, which is less than 42 so it is not the correct combination;
Similarly, the second and last gives only 24 so it is not the correct combination;
This leaves the only remaining option of the third and fifth;
30 + 16 = 46, which confirms this to be the correct combination.
No solutions.
To solve, set the two equations equal to each other.
6x +9 = 6x +2
cross out the 6x
9 = 2
there are no instances where 9 = 2, so there are no solutions.

The final value of the truck after depreciation and the number of years you own the truck are the two variables in this problem.
The dependent variable is the final value of truck after depreciation and the independent variable is the number of years you own the truck.
We are given that the initial value of truck is $12,400 and depreciation value per year is $820.
We know that,
Final Value = Initial Value - Depreciation value per year * Number of years
Let Final value be y
Let the number of years be x.
Hence, the equation will be:-
y = 12400 - 820*x
y = 12400-820x
We can clearly see from the equation that the final value of truck will depend on the number of years you own the truck.

Answer:
b. A smaller sample size would increase the effectiveness of a hypothesis test.
Step-by-step explanation:
A hypothesis test is an important procedure in the field of statistics. It evaluates any two mutually exclusive statements about a population that determines and tells which statement made best supports to the sample data provided.
Now we know that an increase in the sample size makes the hypothesis test more effective and sensitive and it is more likely to reject the null hypothesis.
The probability of making a type I error is known as the Alpha while the probability of making type II error is called Beta.
Thus the correct option is (b).
