The answer can be written as a fraction 1876/25 or as a decimal of 75.04.
<span>Answer:
The notation for the uniform distribution is
X ~ U(a, b), where a = the lowest value and b = the highest value
In your case, X ~ U(66,89)
µ = (b+a)/2
Ď = (b-a)²/12
In this case, a = 66 and b = 89
Thus,
µ = (89+66)/2 = 77.5
Ď = (89-66)²/12 = 44.0833
Then, because we now know the true/population µ and Ď, we can use z-scores.
z = (X-µ)/Ď
In our case, X = 71. So,
Z = (X-µ)/Ď
Z = (71-77.5)/44.0833 = -0.15
P(Z>-0.15) = P(Z<0.15) = 0.5596</span>
<h3><u>The variable is equal to 20.</u></h3>
6w + 30 + w = 4w + 90
Subtract 30 from both sides.
6w + w = 4w + 60
Combine like terms.
7w = 4w + 60
Subtract 4w from both sides.
3w = 60
Divide both sides by 3.
w = 20
The answer is G. Perpendicular lines have opposite reciprocal slopes
Answer:
24+14
Step-by-step explanation:
You need to rearrange the terms like this:
2(7+12b)
2(12+7)
And your answer is 24+14
