Answer:

the standared deviation =2.87 so it is small

Step-by-step explanation:

to calculate the standard deviation of those numbers:

1- Work out the Mean (the simple average of the numbers)

(7+6+5+8+9+1+0+4+3+2)/10=4.5

Then for each number: subtract the Mean and square the result.

[(7 - 4.5)^2 + ... + (2 - 4.5)^2]/10=8.25

√8.25=2.87≅3

allsm [11]

Answer:

The monthly cash inflow is $273.6

Step-by-step explanation:

It is given that hourly wage is $18 and his net pay is 72% of his earnings.

First, calculate the 72% of $18.

72% of his earnings is $\$18\times \frac{ 72}{100}= \$12.96$ .

Tyrone works 40 hours per week .

The number of working hours in a month is: $40\times4=160 \text{ hours}$

For 1 hour is he was getting $12.96.

For 160 hours he will get: $160\times 12.96=\$2073.6$

His total monthly cash inflow is $2073.6 - $1,800=$273.6

Hence, the monthly cash inflow is $273.6

I don't understand the bottom with 1/2= and 0.48=! It says find the corresponding equivalent for either the decimal or fraction

zepelin [54]

So basically, you have to find the decimal that equals 1/2 and the fraction that equals 0.48, but it has to be in simplest form. If you divide 1 by 2, you get 0.5, which would be the answer to 1/2=. For 0.48=, you would start by putting 48 over 100 because if you read the decimal aloud, it is 48 hundredths and 0.48 goes to the hundredths place. Then, you would begin to simplify 48/100. A common divisor for those 2 numbers is 2, but you could also use 4. I am going to use 4, so 48/100=12/25. Now that you have the fraction 12/25, look to see if there are any common factors. There are none, so 0.48=12/25.
Hope this helps!! :)

Select the correct answer.

hammer [34]

Answer:

(A)

Step-by-step explanation:

The domain of the function are the inputs, or x-values, of the function.

{(6,-8), (9,3), (-3,5), (1,-6), (5,7)}

The domain is: {-3, 1, 5, 6, 9}.

This eliminates B, C, and D, because their domains do not match the ones we have.

We need to check to see if it matches the range as well.

The range of the function are the inputs, or y-values of the function.

{(6,-8), (9,3), (-3,5), (1,-6), (5,7)}

The range is: {-8, -6, 3, 5, 7}

A matches this range too.

A is the best answer.

A fair dice is thrown what is the probability that a 6 4or 5 is thrown

antiseptic1488 [7]

There is a 3/6 or 1/2 chance that a 6, 4, or 5 is thrown. This is because a fair dice has as 6 sides, therefore, as three numbers were listed, there is a 3/6 probability that 6, 4 or 5 will be thrown.
