A rectangular prism with a volume of 6 cubic units is filled with cubes with side lengths of 1/2

Delicious77 [7]

Answer:

48 cubes are needed to fill the prism

Step-by-step explanation:

To solve this problem we first have to calculate the volume of the cube

1/2 units= 0.5 units

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

v = volume

s = side = 0.5 u

v = s * s * s

we replace the values that we know

v = 0.5 u * 0.5 u * 0.5 u

v = 0.125 u³

The volume of the cube prism is 0.125 u³

Now we have to divide the volume of the prism by the volume of the cubes

6 u³ / 0.125 u³ = 48

48 cubes are needed to fill the prism

The table below shows the distance a train traveled over time. How can you determine the equation that represents this relations

n200080 [17]

Answer:

see the explanation

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in seconds

y ---> the distance in meters

In this problem we have a proportional relationship between the variables x and y

Find the constant of proportionality k

$k=\frac{y}{x}$

For x=2, y=25 ---> $k=\frac{25}{2}=12.5$

For x=4, y=50 ---> $k=\frac{50}{4}=12.5$

For x=6, y=75 ---> $k=\frac{75}{6}=12.5$

For x=8, y=100 ---> $k=\frac{100}{8}=12.5$

The value of k is $12.5\ \frac{m}{sec}$

In this problem the value of k or slope represent the speed of the train

The linear equation is equal to

$y=12.5x$

$Distance=12.5Time$

: A marker in the shape of a cylinder has a diameter of 14 mm and a height of 136 mm. Find the volume of the figure described. U

Lerok [7]

Answer:

The volume of the figure is 20,925.0mm^3.

Step-by-step explanation:

Firstly we know that the Diameter = 14mm and Height = 136mm.

Area of Circle = 3.14xR^2 Radius = Diameter / 2

Area of Circle = 3.14x7mm^2 = 153.86mm

Volume = 153.86 x 136 = 20,924.96

Then round, to get 20,925.0

Let me know if this is helpful

There is a 0.9989 probability that a randomly selected 32 year old male lives through the year. A life insurance company charges

densk [106]

Answer:

$53.83

Step-by-step explanation:

The question is <em>"What is the expected value for the insurance company?"</em>

<em />

The expected value is the sum of the product of each possibility and its probability.

Thus, we have:

The probability of living is 0.9989 and its value is 153

THe probability of dying is (1-0.9989=0.0011) and its value is -90,000

Now, the expected value is:

E(x) = (0.9989)(153) + (0.0011)(-90,000) = $53.83

In an article about disinflation, various investments were examined. The investments included stocks, bonds, and real estate. Su

kykrilka [37]

Answer:

Step-by-step explanation:

Using the formula for calculating the confidence interval to estimate an interval for the mean rate of return on all real estate investments with 95% confidence;

Confidence Interval = xbar±(Z*S/√n)

xbar is the mean = 20%(assumed since we are not given)

n is the sample size = 200

S is the standard deviation = 2.25%

Z is the Z score at 95% confidence interval = 1.960

Confidence Interval = 20±(1.96*2.25/√200)

Confidence Interval = 20±(1.96*2.25/14.14)

Confidence Interval = 20±(1.96*0.159)

Confidence Interval = 20±0.312

Confidence Interval = (20-0.312, 20+0.312)

Confidence Interval = (19.688, 20.312)

Hence the interval for the mean rate of return on all real estate investments with 95% confidence is 19.688<x<20.312.

This means that the minimum rate of return on investment is 19.688% and the maximum rate of return on investment is 20.312%.(assuming 20% as the mean)
