Answer:
x = 0.85476
Step-by-step explanation:
4ˣ/9ˣ=½
9ˣ / 4ˣ = 2
(9/4)ˣ = 2
2.25ˣ = 2 .... aⁿ = x logₐx = n
log₂.₂₅2 = x
x = 0.85476
Answer:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes

Answer:
The mean score is 7.31. This means that each time the student takes this test, he is expected to get a score of 7.31.
Step-by-step explanation:
We have these following probabilities:
A 0.07 = 7% probability that the student scores 5 points.
A 0.17 = 17% probability that the student scores 6 points.
A 0.38 = 38% probability that the student scores 7 points.
A 0.21 = 21% probability that the student scores 8 points.
A 0.1 = 10% probability that the student scores 9 points.
A 0.07 = 7% probability that the student scores 10 points.
Mean score
We multiply each score by it's probability. So
The mean score is 7.31. This means that each time the student takes this test, he is expected to get a score of 7.31.
