Morgarella [4.7K]

An integer is a whole number, in other words, a number that isn't a fraction or decimal.

0 + 0 + -2 + -2 + 2 + -2 = -4

-4 is an integer because it is not a fraction or decimal.

Best of Luck!

The average age of instructors at a local college is 55, with a standard deviation of 6 years; the average salary is $37,000 wit

Lerok [7]

To solve for the coefficient of variation you will need this formula:
CV = (SD/X) x 100
Where: CV = Coefficient of Variance
X = Mean/average
SD = Standard Deviation

To determine which one is more variable, just get the coefficient of both and compare.
AGE SALARY

CV = (6/55) x 100 CV = (4,100/37,000) x 100
= 10.90 = 11.08

Based on the results, salary is more variable because 10.90<11.08.

Answer:

Answer is option b)

${(x - 3)}^{2} + {(y - 4)}^{2} = 400$

Your guess was right.

Step-by-step explanation:

$the \: question \: states \: that \: \\ distance \: between \: two \: points \: is \: 20 \: units \: \\ and \: the \: two \: points \: are \: (x,y) \: \: and \: \: (3 ,- 4) \\ distance \: formula \\ = \sqrt{ {(x1 - x2) }^{2} + {(y1 - y2)}^{2} } \\ on \: substituting \: the \: values \: in \: formula \\ 20 = \sqrt{ {(x - 3)}^{2} + {(y - ( - 4))}^{2} } \\ 20 = \sqrt{ {(x - 3)}^{2} + {(y + 4)}^{2} } \\ now \: squaring \: on \: both \: sides \\ 400 = {(x - 3)}^{2} + {(y + 4)}^{2} \\ hence \: the \: answer \: is \: option \: b)$

HAVE A NICE DAY!
