frank has two same size rectangles divided into the same number of equal parts. one rectangle has 3/4 of the parts shaded, and t

he other has 1/3 of the parts shaded. Part A into how many parts could each rectangles be divided? show your work by drawing the parts of each rectangle Part B is there more than one possible answer to part A? if so, did you find the least number of parts into which both rectangles could be divided, explain your reasoning.

This question basically asks for the LCM of 3 and 5, which is 3 x 5 =15

This is the answer: 15

Check : The first rectangle had 1/3 shaded; ( one in every three parts)

So for 15 parts  altogether, 5 would be shaded ( 1/3 = 5/15)

The second rectangle had 2/5 shaded ( two for every five parts)

So for 15 parts altogether, 6 would be shaded (2/5 = 6/15)

Answer:

The probability of the stick's weight being 2.33 oz or greater is 0.0041 or 0.41%.

Step-by-step explanation:

Given:

Weight of a given sample (x) = 2.33 oz

Mean weight (μ) = 1.75 oz

Standard deviation (σ) = 0.22 oz

The distribution is normal distribution.

So, first, we will find the z-score of the distribution using the formula:

z=\frac{x-\mu}{\sigma}

Plug in the values and solve for 'z'. This gives,

z=\frac{2.33-1.75}{0.22}=2.64

So, the z-score of the distribution is 2.64.

Now, we need the probability P(x\geq 2.33 )=P(z\geq  2.64).

From the normal distribution table for z-score equal to 2.64, the value of the probability is 0.9959. This is the area to the left of the curve or less than z-score value.

But, we need area more than the z-score value. So, the area is:

P(z\geq  2.64)=1-0.9959=0.0041=0.41\%

Therefore, the probability of the stick's weight being 2.33 oz or greater is 0.0041 or 0.41%.
