Mean - add up all of the scores, and divide it by the number of members:

68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
462 / 7 = 66

ANSWER: The mean is 66

Median - write out all the numbers in order, and select the middle value:

60, 62, 64, 66, 68, 70, 72

ANSWER: As you can see, 66 is the middle value.

Midrange - find the mean (average) of the smallest and largest number:

Largest number: 72
Smallest number: 60

Midrange:   72 + 60 = 132
                     132 / 2 = 66

ANSWER: So the midrange is 66

1/3 of a number is 12 less than the number itself
natulia [17]
Let "x" be a substitute for "a number"

1/3(x)=x-12    Multiply by 3
x=3x-36         Get n onto the same side of the equation
2x=36            Divide by 2
x=18

That's your answer.

What are the degree and leading coefficient of the polynomial of 12u3 -8 + 23u
irga5000 [103]

Answer:

Degree: 3

Leading Coefficient: 12

Step-by-step explanation:

Find the highest power to determine the degree, in this case it's 3. Then identify the term with the highest power (12u^3) to find the leading coefficient.

So, because 3 is the largest and only power in this equation, it is the degree. 12u^3 is the leading term (term containing the highest degree) and 12 is the coefficient attatched to the term. Hope that helped!

Which of the following is equal to the rational expression when x doesnt equal 5? x^2 - 25/ x - 5
scoundrel [369]
The complete question in the attached figure

we have that
(x²<span> - 25)/ (x - 5)

we know
</span>(x² - 25)-------------> (Difference of two squares)----------> (x+5)*(x-5)

then

(x² - 25)/ (x - 5)<span>-------> (x+5)*(x-5)/(x-5)------------> (x+5)

the answer is the option B)
(x+5)</span>

The equation for future value F of principal P over t years at r% interest compounded continuously is

F=Pe^(rt) =>
8000 = 4000*e^(0.04*t)
Solve for t:
e^(0.04t)=8000/4000=2
0.04t=log(2)
t=log(2)/0.04=17.33 (years)
