An empty box is shaped like a rectangular prism. The box has a base area of 9/10 square foot and a height of 1/3' foot. How much
sveticcg [70]

Answer: (A)

Packing material is required to fill the box = \frac{3}{10} ft^{3}

Step-by-step explanation:

The box is shaped like a rectangular prism

base area = 9/10 square foot

height = 1/3 foot

Volume of a prism = base area X Height

=\frac{9}{10}X \frac{1}{3}=\frac{3}{10} ft^{3}

What’s the approximate value of x?
drek231 [11]

Answer:

Option C: 4

Step-by-step explanation:

<u>Use the Pythagorean Theorem:</u>

a^2+b^2=c^2

3^2+b^2=5^2

9+b^2=25

b^2=16

b=4

Rachael got a 550 on the analytical portion of the Graduate Record Exam (GRE). If GRE scores are normally distributed and have m
valina [46]

Answer:

Z=-2

This value means that the score of Rachel 550 it's 2 deviations below the mean of the population \mu=600

Step-by-step explanation:

1) Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

\mu=600 represent the population mean for the Graduate Record Exam (GRE)

\sigma=25 represent the population standard deviation for Graduate Record Exam (GRE)

2) Solution to the problem

Let X the random variable that represent the Graduate Record Exam (GRE) of a population, and for this case we know the distribution for X is given by:

X \sim N(600,25)  

Where \mu=600 and \sigma=25

We want to find the z score for a score of 550. And in order to do this we need to apply the formula for the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

z=\frac{550-600}{25}=-2

So the answer for our case would be Z=-2

This value means that the score of Rachel 550 it's 2 deviations below the mean of the population \mu=600
