Given :

A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.

To Find :

The length of the frame.

Solution :

We know, perimeter of the rectangle is given by :

P=2(l+b)\\\\P=2(3x+x)\\\\P=8x

Now, it is given that 18 feet of wood is used.

So,

8x=18\\\\x = 2.25\ feet

Therefore, length of frame is given by  3x = 6.75 feet.

Hence, this is the required solution.

The answer is A) 5b

Lets try an example:

Lets say we have 3 boxes in total of both board games. We can solve for b since b = 3 in the example.

= 5b

= 5(3)

= 15 dice in total

We can check our answer by adding the amount of dice per box.

2 + 3 = 5

Then multiplying by the number of boxes.

5 * 3 = 15 dice total

Scores on an English test are normally distributed with a mean of 31.5 and a standard deviation of 7.3. Find the score that sepa
vladimir1956 [14]

If X is a random variable representing test scores, then the 41st percentile is the score x such that P(X\le x)=0.41. Transform X to the random variable Z that follows the standard normal distribution via X=31.5+7.3Z:

P(X\le x)=P\left(\dfrac{X-31.5}{7.3}\le\dfrac{x-31.5}{7.3}\right)=P\left(Z\le\dfrac{x-31.5}{7.3}\right)=0.41

The z-score for the 41st percentile is about -0.2275, so

\dfrac{x-31.5}{7.3}\approx-0.2275\implies\boxed{x\approx29.8}
