Hi!
Let's find the volume of the cylinder first.
The equation to find the volume of a cylinder is
(r = radius, h = height)
v = πr²h
Fill in the values
v = π · 100² · 250
Solve
v = π · 10000 · 250
v = π · 2500000
v = 7853981.63
Now since the cylinder is half-full, divide by 2.
7853981.63/2 = 3926990.81
To find how many liters are in the container, divide
1 liter = 1000
3926990.81/1000 = 3926.99081
Round to the nearest liter
3927
There are 3927 liters in the cylindrical tank
Hope this helps! :)
The probability that x will be at most 2 will be 0.89.
<h3>What is probability?</h3>
It should be noted that probability simply means the likelihood of the occurence of an event that's given.
Based on the information, let the number of points that can be scored on the statistics examination be depicted by x.
Therefore, the probability that x will be at most 2 will be:
= P(x = 0) + P(x = 1) + P(x = 2)
= 0.13 + 0.21 + 0.55
= 0.89
Therefore, the probability that x will be at most 2 will be 0.89.

Answer:
Her brothers pulse rate is 76.
Step-by-step explanation:
95% of 80 is 76. That only means that her brother's pulse rate must be 76 beats per minute.
3xy-5x+9y-45
Step-by-step explanation:
Step by Step Solution
STEP1:STEP2:Pulling out like terms
2.1 Pull out like factors :
3y - 15 = 3 • (y - 5)
Equation at the end of step2: (x • (3y - 5)) + 9 • (y - 5) STEP3:Equation at the end of step 3 x • (3y - 5) + 9 • (y - 5) STEP4:Trying to factor a multi variable polynomial
4.1 Split 3xy-5x+9y-45
