First take the inside diameter and divide by 2 to get the radius (4cm)
Then use $\pi$ r^2 with 'r' being your radius to get the area of the base
The area is 12.7 cm
Now multiply the height by the area of the base to get the volume/ capacity!
40cm x 12.7cm (rounded to the nearest tenth) = 502.7 cubic centimeters

Given that z is a standard normal random variable, find the value of z for each situation. a. The area to the right of z is 0.01

otez555 [7]

Answer: =1.34

Step-by-step explanation:

In standard density curve

P(Z<z) = Area left of z, P(Z>z) = area right of z.

P(Z<z) +P(Z>z) =1

Given: z is a standard normal random variable.

To find : value of z if rea to the right of z is 0.01.

i.e. P(Z>z) =0.01

P(Z<z) =1-0.01 = 0.09

from z-score table, z value for this is 1.34.

Hence, z= 1.34

in a bag of marbles, you have 3 green, two yellow, six blue, and nine red marbles. What is the probability of picking a red marb

BlackZzzverrR [31]

So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator.
All of the other numbers would be your numerator. So you would have:

3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles

So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%

$3 \sqrt{7} \sqrt{7} = 3 \sqrt{ {7}^{2} } = 3 \times 7 = 21 \\ 6 \sqrt{ {7}^{5} } = 6 \sqrt{ {7}^{4} \times 7 } = 6 \times {7}^{2} \sqrt{7} = 294 \sqrt{7} \\ \frac{21}{294 \sqrt{7} } = \frac{1}{14 \sqrt{7} } \\ \\ or \: \frac{1}{14 \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} } = \frac{ \sqrt{7} }{14 \times 7} = \frac{ \sqrt{7} }{98}$

Change 00345 to a percent.

Wewaii [24]

It would be .345% because to change it to a percent all you have to do is move the decimal point two places to the right.
