To the nearest tenth, find the volume of a sphere with a diameter of 36 cm. Use 3.14
lesya [120]

Answer:

The volume of the sphere is 24416.6 cm³

Step-by-step explanation:

To calculate the volume of a sphere we have to use the following formula:

v = volume

r = radius

v = ⁴⁄₃πr³.

To solve this formula we first have to have all the data, as we see we need to calculate the radius, which is calculated by dividing the diameter by 2

r = d/2

r = 36cm/2

r = 18cm

Now that we have all the data we can solve the formula

v = ⁴⁄₃πr³.

v = ⁴⁄₃ * 3.14 * (18cm)³

v = 24416.64 cm³

Round to the nearest tenth

v = 24416.6 cm³

If x= -8 and y=-4​, evaluate the expression.<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3x-4%7D%7By-3%7D" id="TexFormula1"
bagirrra123 [75]

Your answer would be 4.

If we substitute in x = -8 and y = -4 into the expression, we get:

\frac{3(-8) - 4}{-4 - 3}

This then becomes:

\frac{-24 - 4}{-7} = \frac{-28}{-7} = 4.

I hope this helps!

4. The annual salaries of employees in a large company are approximately
svetoff [14.1K]

a. What percent of people earn less than $40000?

Solution: Let S be the random variable of a salary of employee (in $), S ~ N(50000,20000). Then the random

variable X =−50000

20000

~N(0,1).

( < 40000) = ( <

40000 − 50000

20000 ) = ( < −0.5) = (−0.5) = 0.3085375.

Here Φ(x) denotes the cumulative distribution function of a standard normal distribution.

Answer: 31%.

b. What percent of people earn between $45000 and $65000?

Solution:

(45000 < < 65000) = (

45000 − 50000

20000 < <

65000 − 50000

20000 ) = (−0.25 < < 0.75)

= (0.75) − (−0.25) = 0.7733726 − 0.4012937 = 0.3720789.

Answer: 37%.

c. What percent of people earn more than $70000?

Solution:

( > 70000) = ( >

70000 − 50000

20000 ) = ( > 1) = 0.8413447.

Answer: 84%.
