Answer: C.) 4/27

Step-by-step explanation:

Given that:

One out of three cards is a winner :

P(winning) = 1 / 3

Therefore, P(not winning) = P(losing) :

1 - P(winning) = 1 - 1/3 = 2/3

Probability that shenice will first win on her third try can be interpreted as:

1st try = lose, 2nd try: lose, 3rd try : win

P(losing) × p(losing) × p(winning)

(2/3) × (2/3) × (1/3)

4 / 27

Probability of first winning on third try = 4/27

Mikayla is a waitress who makes a guaranteed $50 per day in addition to tips of 20% of all her weekly customer receipts, t. She
notsponge [240]

Answer:

D. f(t)=300+0.20t

Step-by-step explanation:

We have been given that Mikayla is a waitress who makes a guaranteed $50 per day.

Since Miklaya works  6 days per week, so the guaranteed income for one week would be \$50\times 6=\$300  

We are also told that she gets tips of 20% of all her weekly customer receipts, t. So amount earned from tips would be 20% of t, that is \frac{20}{100}t=0.20t.

Total amount earned in one week would be guaranteed income for 1 week plus 20% of t:

300+0.20t

Therefore, our required function is f(t)=300+0.20t and option D is the correct choice.

What is the slope of the line that goes through -3,7 & -17,3
Natalka [10]

Point 1: (-3, 7)

Point 2: (-17, 3)

To find the slope, we need to use the slope formula which is as follows: m = (y2 - y1) / (x2 - x1). We will plug in each x and y coordinate from our points above, respectively.

m = (3 - 7) / (-17 - - 3)

m = (-4) / (-14)

m = 2/7

The slope of the line that goes through (-3, 7) and (-17, 3) is 2/7.

Hope this helps!! :)

0.27 (repeating) into a fraction. Simplify if needed.
WARRIOR [948]
Dont ask me why...I cant really explain it...but if u have 1 repeating decimal, u put it over 9. If u have 2 repeating decimals, u put it over 99....3 repeating decimals, put it over 999.

Examples :
0.7 (repeating) = 7/9
0.27 (repeating) = 27/99 when simplified = 3/11 <===
0.444 (repeating = 444/999

Please show steps in solving: B/3 + B/4 + B/6 =
alexandr1967 [171]

Answer:

= 3b/4

Step-by-step explanation:

= b . 4/12 + b . 3/12 + b . 2/12

Apply the fraction rule: a/c + b/c = a + b/c

= b . 4 + b . 3 + b . 2/12

= 4b + 3b + 2b/12

Add similar elements: 4b + 3b + 2b = 9b

= 9b/12

Cancel 9b/12: 3b/4

= 3b/4
