Answer:
<h2><em><u>
t = 15.2 is the answer</u></em></h2>
Step-by-step explanation:
<h2><em><u>
1. Make an equation</u></em></h2>
numbers to find perimeter = perimeter
Side + Side + 2 unknown sides = perimeter
12 + 7.8 + 2t = 50.2
<h2><em><u>
2. Simplify like terms</u></em></h2>
19.8 + 2t = 50.2
<h2><em><u>
3. Solve</u></em></h2>
19.8 + 2t = 50.2
-19.8 - 19.8
2t = 30.4
<h2><em><u>
t = 15.2</u></em></h2>
<h2><u><em>
4. Check:</em></u></h2>
12 + 7.8 + t + t = 50.2
12 + 7.8 + (15.2) + (15.2) = 50.2
<h2><em><u>
50.2 = 50.2</u></em> Correct!</h2><h2 />

Answer:
118 yards
Step-by-step explanation:
Tamia is getting balloons for her father's birthday party
She wants each balloon to be 6 feet long
Tamia wants to get 59 balloons
Therefore the yards of string needed can be calculated as follows
= 59×6
= 354 feet to yards
= 118 yards
Hence the number of yards needed is 118 yards
2 over 9 because if you see there are 3 red and 4 blue

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

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>

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
