Answer:
Step-by-step explanation:
Since we have given that
A toy manufacturer claims that the mean time that its top-selling toy captures children's attention is at least 45 minutes.
Since we need to carry out a hypothesis test whether he can refute the claim.
We always take the alternate hypothesis such that it should satisfy the given statement.
And the null hypothesis can be equal to mean or other than that is given in alternate hypothesis.
So, hypothesis :
Answer:
The volume of the solid is either 346.5 in³ or 693 in³.
Step-by-step explanation:
The solid can either be a triangular prism or a rectangular cube.
The volume of a triangular prism is:
Here,
B = base
H = height
L = length
Let,
B = 7 in
H = 9 in
L = 11 in
Compute the volume of a triangular prism as follows:
Thus, the volume of a triangular prism is 346.5 in³.
The volume of a rectangular cube is:
The values of L, B and H remains the same as above.
Compute the volume of a rectangular cube as follows:
Thus, the volume of a rectangular cube is 693 in³.
