I'm pretty sure the answer is 452.16.
The formula is pi times the radius squared times the height.
3.14 times 6 squared time 4.
3.14 times 36 times 4.
113.04 times 4.
452.16.
Answer:
A manufacturing machine has a 40% defect rate. If 131 items are chosen at random, then:
- The random variable, X=Number of 131 randomly selected items that are defective.
- Number of Items, n=131
- The point estimate of defective items, p=40%=0.4
Answer:
25
Step-by-step explanation:
If one box of rice feeds 5 students, then 5 boxes of rice will feed: 5 x 5 = 25 students
There is a totaly of 50 students, and only enough rice for 25 students. Therefore, the number of students who will not get rice = 50 - 25 = 25
Answer:
x=7.999996
Step-by-step explanation:
273x=81x+10
log(273x)=log(81x+10)(Take log of both sides)
3x*(log(27))=(x+10)*(log(81))
3x=(
log(81)
log(27)
)*(x+10)
3x=1.333333*(x+10)
3x=1.333333x+13.33333(Simplify both sides of the equation)
3x−1.333333x=1.333333x+13.33333−1.333333x(Subtract 1.333333x from both sides)
1.666667x=13.33333
1.666667x
1.666667
=
13.33333
1.666667
(Divide both sides by 1.666667)
<u>Answer:</u>
45
<u>Step-by-step explanation:</u>
We are given an equation <em>x - y = 30 </em>which we are to solve for x when the value of y is 15.
To solve this linear equation for x, we just need to substitute the given value of y into the equation to get the value of x.
x - y = 30
x - 15 = 30
x = 30 + 15
x = 45
Therefore, the value of x is 45 when y = 30.
Unfortunately this value is not in the given options but 45 is the correct answer.
