Answer:
P(2.5≤X≤4) = 0,3125
Step-by-step explanation:
We know that the area under the curve of ANY probability distribution should not be greater than 1.
In this case, we now that 4P = 1, therefore, P=1/4. Where 'P' represents the height of the rectangle that represents the probability distribution.
The probability of P(2.5≤X≤4) will be given by the area of the following rectangle:
(4 - 2.5) × 1,5 = 0,3125
Therefore, P(2.5≤X≤4) = 0,3125
Answer: 
Step-by-step explanation:
Given
The dimension of the rectangular box is 
If the Straw fits exactly into the box diagonally
So, the length of the longest diagonal of the rectangular box is equal to the length of the straw i.e.

The answer is: She had more math assignments to start with, but completed more science assignments weekly.
Step-by-step explanation:
7 + x/3 =2x - 5
7 + 5=2x - x/3
12 = 5x/3
cross multiply
36=5x
x=36/5
x=7.2
