4(9) + 3s = 75
36 + 3s = 75
3s = 39
s = 13
The answer is 1/4 or 0.25.
steps:
first look in the parenthesis and notice that the denominator is not the same. set the denominator to 6 for the fraction 1/3 by multiplying 3(2) and 1(2) which makes the fraction 1/6. now add -5/6 and 1/6 inside the parenthesis. you should get -3/6 which you should put in the simplest form: -1/2. now combine -1/2 and -1/2 to get 1/4
Answer:
Step-by-step explanation:
( g ° f )(x) = ( x + 7 )² = x² + 14x + 49
20 + 3(x² + 14x + 49) = - 34
20 + 3x² + 42x + 147 = - 34
3x² + 42x + 201 = 0 ⇔ x² + 14x + 67 = 0
D = 196 - 268 = - 72 < 0

Does the given information
describe a probability distribution?
</span>
Yes
<span>
Assuming that a probability
distribution is described, find its mean and standard deviation.
</span>
The mean is equal to 0.6. The standard deviation is equal to 1.5
<span>
Use the range rule of thumb to
identify the range of values for usual numbers of bumper stickers.
</span>
<span>The
maximum usual value is 3.5.</span>
<span>max: μ + 2σ = 0.578 + 2(1.462161414) =
3.502322828</span>
<span>The
minimum usual value is 0.</span>
<span>min: μ – 2σ = 0.578 – 2(1.462161414) =
-2.346322828</span>
<span>
Is it unusual for a car to have
more than one bumper sticker? Explain.
</span>
No, because the probability of
having more than one bumper sticker is equal to 0.120 that is greater that 0.05
