Answer:
t = 300
Step-by-step explanation:

Step-by-step explanation:
To figure out the variance, subtract 82.5 from the mean, which is 5.5 and then divide by N, which is the value of numbers, (in this case 10) minus 1. The result is a variance of about 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.Calculate the mean.
Subtract the mean from each observation.
Square each of the resulting observations.
Add these squared results together.
Divide this total by the number of observations (variance, S2).
Use the positive square root (standard deviation, S).

Answer:
The length of the portion BC of the cloth is 4.56 inches long.
Step-by-step explanation:
I suggest drawing the triangle out! It'll make it a lot easier to solve!
A
|35\ 8 inches
| \
B |90 _\ C
x inches
Here you can use SOH CAH TOA
SOH = Sin theta = Opposite/Hypotenuse
CAH = Cos theta = Adjacent/Hypotenuse
TOA = Tan theta = Opposite/Adjacent
We are going to use Sin because we have the hypotenuse and we're solving for opposite.
Sin theta (angle) = Opposite/Hypotenuse
Sin (35) = x/8
Sin (35) = 0.57 (Use a calculator)
0.57 = x/8 Now we're going to solve for x (segment BC)
0.57*8 = x
4.56 = x
The length of the portion BC of the cloth is 4.56 inches long.
I believe the correct answer is false. Quadratic equations that can be solved using the quadratic formula cannot always be solved by factoring. <span>Not </span>all quadratic equations can<span> be </span>solved by factoring<span>. Another method that can be used is completing the square. Hope this answers the question.</span>
