Given: Kristen made 4 out of 5 throws in her first basketball game, 5 out of 8 in her second game and 5 out of 7 free throws in her third game.

To Find: The experimental probability of Kristen marking her first free throw in her fourth game.

Solution:

There are only two possibilities that the first throw will be free or not.

Hence, the total outcomes = 2

Hence, Probability that the throw is free = $(1)/(2)$

Hence, 1/2 is the experimental probability of Kristen marking her first free throw in her fourth game.

Lorenzo is a salesman whose base pay plus commissions amounted to $53,393 last year. If his base pay was $24,650 and he made $87,100 in sales last year, what was his rate of commission?A. 33%

B. 28%

C. 46%

D. 61%

Answers

Since, a salesman whose base pay plus commissions amounted to $53,393 last year. If his base pay was $24,650 and he made $87,100 in sales last year. We have to evaluate the rate of commission.

Let the rate of commission be 'r%'.

Therefore,

24,650 + (87,100 of r%) = 53,393

$24,650 +(87,100 * (r)/(100))= 53,393$

$(87,100 * (r)/(100))= 53,393-24,650$

$(87,100 * (r)/(100))= 28,743$

$87,100 * {r}= 28,743 * 100$

$87,100 * {r}= 2874300$

${r}= (2874300)/(87100)$

r = 33%

Therefore, the rate of commission is 33%.

The Answer is Choice D.

A company has two electric motors that consume varying amounts of power. The power consumed by each motor is a function of the time (t in minutes) for which it runs. The cost of power (in $) to run one motor is given by the function `C_a(t) = t^2 - 2t + 5`. The cost of running the second motor is given by `C_b(t) = 3t + 2`. Which function gives the total cost of running both motors?

You are a contractor who is installing new windows. You are working on a house that has 6 windows that are each 3 feet by 4 feet.If the glass for the windows costs $0.05 per square inch, approximately how much money will the glass cost for all of the window installations?

A.
$36
B.
$43
C.
$432
D.
$518

Answers

Answer:

D. $518

Step-by-step explanation:

We know that the windows are 3ft by 4ft, find the area:

A = L * W

A = 3ft * 4ft

A = 12 sq ft

12 sq ft is the area of each window in the house

Now multiply the amount of windows in the house by the 12 sqft:

12 sqft * 6

72 sq ft

The combined area of all 6 windows are 72 sqft. Now since 1 sqft is equal to 144 sq inches, simply convert the square feet into squared inches:

72 * 144

10,368 squared inches

Since each square inch costs 0.05 cents, multiply the amount of square inches by the cost of each square inch:

0.05 * 10,368

$518.4

Since D. is the closest value, that would be our answer.

Suppose that g(x) = f(x)*h(x), f(3) = 6, h(3) = 2, h'(6)=4, h'(3) = 15 and f'(3) = 8. Find g’(3). (A) 32 (C) 106 (B) 8 (D) 60

Answers

Answer:

Step-by-step explanation:

C (106)

g(x)=f(x)*h(x) ⇒g'(x)=f'(x)*h(x)+f(x)*h'(x) ⇒ g'(3)=f'(3)*h(3)+f(3)*h'(3)⇒ g'(3)=(8*2)+(6*15)= 16+90=106

Which of the following is another way to express the equation 16 = -9 + z?

Answers

Since you didn't give the options, we'll answer In steps and you can pick which step you have as an answer choice...

16 = -9 + z

Add 9 to each side for

16 + 9 = z (that's one option)

Add like terms for

25 = z (there's another)

You could also go a whole different route and take the original equation

16 = -9 + z

subtract z from each side for

16 - z = -9

Any of those would be another way to express the equation.

Answer:

16 = -z - 9
