Answer:

315

Step-by-step explanation:

If i understand this correctly, you just need to get the volume of the box and divide it by the volume of the 1/2 cube to see how many will fit.

# 1/2in cubes = (5.25 * 3 * 2.5)/(0.5 * 0.5 * 0.5)

# 1/2in cubes = (39.375)/(0.125) = 315

The living spaces of all homes in a city have a mean of 2300 square feet and a standard deviation of 500 square feet. Let x be t
antoniya [11.8K]

Answer:

the mean and standard deviation is 2300 and 100 respectively

Step-by-step explanation:

Given that

Mean = 2300

Standard deviation = 500

let us assume the x be the mean of living space

And, the sample is of 25 homes

We need to find out the mean and the standard deviation

So here mean = 2300

And, the standard deviation

= 500 ÷√25

= 500 ÷ 5

= 100

hence, the mean and standard deviation is 2300 and 100 respectively

azamat

Answer:

The answer would be -3.

Step-by-step explanation:

If you follow PEMDAS, the first set of parenthesis, (-4)(2), would equal -8. The next set of parenthesis, (10/2), would equal 5. Adding -8 and 5 together gives you -3.
