Answer:
V = 23π/6
Step-by-step explanation:
V = 2π ∫ [a to b] (r * h) dx
y = −x² + 23x − 132
y = −(x² − 23x + 132)
y = −(x − 11) (x − 12)
Parabola intersects x-axis (line y = 0) at x = 11 and x = 12 ----> a = 11, b = 12
r = x
h = −x² + 23x − 132
V = 2π ∫ [11 to 12] x (−x² + 23x − 132) dx
V = 23π/6
Answer:
1/100.
Step-by-step explanation:
So, we can make the following deductions from the information given in the question or problem above.
[1]. "You and your neighbor attempt to use your cordless phones at the same time."
DEDUCTION: Two people are involved, that is you and your neighbor are both involved.
[2]. "Your phones independently select one of ten channels at random to connect to the base unit. "
DEDUCTION: Both cordless phones can choose one channels each which is random. The number of channels available is ten.
Therefore, the probability that both your phone and your neighbor phone pick the same channel can be calculated or determined as follows:
The probability that both your phone and your neighbor phone pick the same channel = probability that both your phone will pick one channel out of the ten channels × the probability that your neighbor phone pick one channel out of the ten channels.
The probability that both your phone and your neighbor phone pick the same channel = 1/10 × 1/10 = 1/100.
Therefore, The probability that both your phone and your neighbor phone pick the same channel = 1/100.
In statistics, the amount of degrees of freedom is
the quantity of values in the final computation of a statistic that are free to
differ. In this case, you can get the answer by adding the number of bags
and subtracting 1.
So in computation, this would look like: 3 + 2 + 1 + 2 - 1 =
7
Therefore, 7 is the degrees of freedom.
<span> 0.81x - 0.45 is subtracted from 3.28x + 1.4
</span>3.28x + 1.4 - (0.81x - 0.45) = 3.28x + 14 - 0.81x + 0.45
= (3.28x - 0.81x) + ( 14 +0.45)
= 4.09x + 14.45
Answer:
$225 = $15 a + $ 10 c
Step-by-step explanation:
Given,
Total price = $225
Cost of concert ticket for adults= $15
Cost of concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Now,
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c
