Answer:
Answer is
a. P (both pumps not available) = 0.016
b. P (both pumps available) = 0.984
Step-by-step explanation:
a. Probability of neither pump is available.
We know that P1 + P2 = 1
P1 = Probability of one pump is available = 0.96
P2 = Probability of a pump not available = 1-0.96 = 0.04
Now the probability of both pump not available will be = P2 x P2
=0.04 x 0.04 = 0.016
b. Probability of both pumps available will be.
Using the equation of probability
P (both pumps available) + P (both pumps unavailable) = 1
P (both pumps available) = (1- P (both pumps unavailable))
P (both pumps available) = 1-0.016
P (both pumps available) = 0.984
Answer:
x3y+7x2y2+10xy3
Step-by-step explanation:
Answer:
14x + 5
Step-by-step explanation:
group all the varaibles with x
2x - 5x + 8x + 3x^2
-3x + 8x + 9x
5x + 9x
=14x
now the regular numbers
3 + 2
=5
now put them together to get
14x + 5
To find the mean of something, add all the numbers then divide by the number of numbers there are.
40,000 + 50,000 + 40,000 + 60,000 + 90,000 = 280,000
Then divide:
280,000/5 = 56,000
The mean of the annual salaries at the company is 56,000

<h3><em><u>Simplify -3y+2x-5y-7x is:</u></em></h3><h3>-8y - 5x</h3>
<em><u>Solution:</u></em>
<em><u>Given that, we have to simplify</u></em>
We can simplify the above expression by combining the like terms
Like terms are terms that has same variable ( with same exponent) with same or different coefficient
From given,
Here, like terms are -3y and -5y
And 2x and -7x
Group the like terms
Combine the like terms
Thus the given expression is simplified
