Answer:

7/12

Step-by-step explanation:

To find the probability of drawing a blue marble you need to find how many marbles there are in total.

So you have to add 3 red marbles, 7 blue marbles, and 2 green marbles to get the total.

So 3 + 7 + 2 = 12

There are 12 marbles in total so now you have to find how many blue marbles there are.

There are 7 blue marbles out of 12 marbles.

Now you have to put this as a fraction to see if it can be simplified.

7/12 cant be simplified, so the probability of drawing a blue marble is 7/12.

pychu [463]

Answer:

30

Step-by-step explanation:

Given :

Mean, m = 30 metric tons

Standard deviation (s) = 1.5 metric ton

Sample size, n = 4

Since the impact force in the test model is normally distributed, the shape of the sampling distribution will also be approximately normal with a mean equal to the mean of the test model.

Hence, the sample mean impact force will be equal to the population mean.

Therefore, sample mean = 30 ; population mean = 30

but L = 5/4  times W
180 inch^2 = 5/4 times W times W

W^2 = (4 x 180)/5
W = 12
but L = 5/4 x W
L = 5/4 x 12
L = 15
