Answer:

The area of the section for the picnic tables is 1,188\ ft^{2}

Step-by-step explanation:

we know that

The area of the schoolyard is equal to the area of a rectangle plus the area of a triangle

so

3,564=44*(2x-x)+\frac{1}{2}(2x-x)*44\\ \\3,564=44x+22x\\\\3,564= 66x\\ \\x=54\ ft

The area of the triangle is equal to

22x=22*54=1,188\ ft^{2}

Solve 4(x + 1) = 4x + 4. Would it be No solution? Or all real numbers?
arsen [322]
Pick any number. Write it in place of 'x'. If the result is a true statement, then your number is a solution of the equation. Do it again with a different number. Then do it again. Does it matter what your number is ?

One employee of a computer store is paid a base salary of $2,000 a month plus an 8% commission on all sales over $7,000 during t
Kaylis [27]

Answer:

$25,000

Step-by-step explanation:

You already have 2,000 so all you need to do is get the other 2,000. So you would have to divide 7,000 by 100 which =70 then multiply it by 8 and you get 560. so times it by 4 you get 2,240 so he would need to sale about 28,000 to get 4240, but it a little over, so the answer to get $4000 is not perfect but the closest is $25,004 which is 7,000/100=70 x 3.5715 which will be $2,000.04.

For a population, the mean is 19.4 and the standard deviation is 5.8. Compare the mean and standard deviation of the following r
Ksivusya [100]

Answer:

The mean of sample (21.6) is greater than population mean and the standard deviation of sample (8.4) is also greater than population standard deviation.

Both values, mean and std are greater than corresponding population values. This means, that our sample overestimates or is skewed to the right in the values of population. Also each specific value is farther apart from the mean so variation is much bigger in our sample than in our population.

Step-by-step explanation:

To calculate the mean, we estimate the avergage of the data as

Mean = Sum(data)/n

Where n is the number of observations of sample. We have;

(25 + 32 +  16 + 12 + 11 + 38 + 22 + 21  + 19 + 20)/10 = 21.6

The standard deviation is the square root of variance. Variance is sum of the deviation of each data point to the sample mean.

Variance = sum i= 1 to n (Xi-xmean)/(n-1)

Where n = 10 the # of observations and xi is each specific data point.

If you calculate it in Excel or or by hand you obtain:

Variance = sum i= 1 to n (Xi-21.6)/(10-1) = 8.4

Both values, mean and std are greater than corresponding population values. This means, that our sample overestimates or is skewed to the right in the values of population. Also each specific value is farther apart from the mean so variation is much bigger in our sample than in our population.
