X=5
Do you need an explanation or is the answer enough?
Answer:
20%
Step-by-step explanation:
Total = 45
Absentees = 9
Percentage = (No. of absentees / total) × 100
= 9 / 45 × 100
= 0.2 × 100
= <u>20%</u>
Answer:
0.0791
Step-by-step explanation:
Given that the probability of white eyes is 1/4 and the probability of red eyes is 3/4, for an individual fly.
Observations are independent
Let A be finding the white eyed fly and B
finding the red eyed fly
P(A) for any random trial= 0.25 and
P(B) = 0.75
Each trial is independent of the other
The probability that at least four flies have to be checked for eye color to observe a white-eyed fly
=Probability for I, II, III and Iv flies to have red eyes * Prob for 5th fly to have white eye
=
Given:
A prism with right triangular base.
Base of triangle = 6 ft
Height of triangle = 8 ft
Height of prism = 7
To find:
The volume of the given prism.
Solution:
The volume of prism is:
...(i)
Where, B is the base area and h is the height of the prism.
In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:




Substituting
in (i), we get


Therefore, the volume of the prism is 168 cubic ft.
