7. A machine produces memory sticks of varying lengths, distributed uniformly between 3mm and 13 mm. Memory sticks longer than 1

Mars2501 [29]

Answer:

The proportion of memory sticks that will be scrapped is 0.3 = 30%.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Distributed uniformly between 3mm and 13 mm.

This means that $a = 3, b = 13$

Calculate the proportion of memory sticks that will be scrapped:

$P(X > 10) = \frac{13 - 10}{13 - 3} = \frac{3}{10} = 0.3$

The proportion of memory sticks that will be scrapped is 0.3 = 30%.

One cup of strawberry yogurt has 42% of the recommended daily allowances of Riboflavin and Protein nutrients. If protein has 2%

zhuklara [117]

If you divide them equally then it would be 21% of riboflavin and 21% of protein then you would have take 2% away from the riboflavin so that would make it 19%. So i think the answer is 19% of riboflavin and 21% of protein.

What is the volume of a right circular cylinder with a diameter of 46. 25 cm and a height of 18. 5 cm? Enter your answer in the

Sedbober [7]

The volume of the right circular cylinder is 31064.54 cm³.

What is the formula for the volume of cylinder?

Formula:

V = πr²h.............. Equation 1

Since,

V = Volume of the right circular cylinder

r = radius of the base of the cylinder

h = height of the cylinder.

We have given that,

r = 46.25/2 = 23.125 cm

h = 18.5 cm

π = 3.14

We have to calculate volume of right circular cylinder.

Therefore,

Substitute these values into equation 1

V = 3.14(23.125²)(18.5)

V = 31064.54 cm³

Therefore

The volume of the right circular cylinder is 31064.54 cm³.
