Please help me answer I need this question right, one more wrong answer and I'll fail
Shkiper50 [21]

Answer: The second option.

Step-by-step explanation:

1. Calculate the first volume assuming that the figure is completed (with no missing part). Therefore, you must apply the formula for calculate the volume of a square prism:

V_A=s^{2}*h

Where s is the side of the base and h is the height.

2. Then:

V_A=(40cm)^{2}*50cm=80,000cm^{3}

4. The volume of the missing part is calculated with the formula of a rectangular prism:

 V_B=l*w*h

Where l is the lenght, w is the width and h is the height. Then:

V_B=(40cm)(40cm-35cm)(50cm-25cm)=5,000cm^{3}

5. Therefore, you must subtract both volumes to obtained the volume of the figure:

V_f=80,000cm^{3}-5,000cm^{3}=75,000cm^{3}

A collection of numerical information, such as the scores on a test, is referred to as simple random sampling.True / False.
Nimfa-mama [501]

Answer:

False. See explanation below.

Step-by-step explanation:

False

A simple random sample "is a subset of a statistical population in which each member of the subset has an equal probability of being chosen"

In other words that means in order to apply a random sampling we need to ensure that we have the same probability of inclusion for every possible element of the population of interest.

And for this case a collection of any numerical information is not referred as random sampling since we don't know if these scores are representative of the population of interest.

And we don't know if this information is obtained using any sampling frame or sampling methodology.

A shopper bought shoes marked 40$ the sales tax is 8% how much did the shopper pay in all
BlackZzzverrR [31]

Answer:

43.20

Step-by-step explanation:

First we need to find the sales tax

tax = price * tax rate

tax = 40 * 8%

     = 40*.08

      =3.2

We final cost is the price plus the sales tax

final cost = price + tax

                = 40+3.2

                = 43.20
