A college's lacrosse team will play 22 games next spring. Each game can result in one of 2 outcomes: a win or a loss. Find the total
possible number of outcomes for the season record.

Answers

Answer: 44 possible outcomes

Step-by-step explanation:

Multiply the number of games by the number of outcomes to find how many possibilities.

22 games * 2 outcomes = 44 possibilities

Interpreting the situation, it is found that there are 23 possible outcomes for the season record.

For each game, there are two possible outcomes.

Hence, if the team plays 1 game, there are two possible outcomes, 0 wins or 1 win.If the team plays 2 games, there are three possible outcomes, 0 wins, 1 win or 2 wins.The same is valid for 3 games, the team can win 0, 1, 2 or 3 games.Hence, for n games, there are n+1 outcomes.

In this problem, there are 22 games, hence 23 possible outcomes.

Out of 100 tickets in a raffle, one ticket will win a $150 prize, one ticket will win a $130 prize, one ticket will win a $110 prize, and one ticket will win a $40 prize. The rest will win nothing. If you have a ticket, what is the expected payoff?

Answers

Answer:

" Expected Payoff " = $ 4.30

Step-by-step explanation:

Consider the steps below;

[tex]Probability of Winning the 150 Dollar Prize - 1 / 100,\\Probability * Money Won = " Expected Payoff " For The 150 Dollar Prize,\\\\1 / 100 * 150,\\" Expected Payoff " - 1.5 Dollars,\\\\Probability of Winning the 130 Dollar Prize - 1 / 100,\\\\1 / 100 * 130,\\" Expected Payoff " - 1.3 Dollars,\\\\Probability of Winning the 110 Dollar Prize - 1 / 100,\\\\1 / 100 * 110,\\" Expected Payoff " - 1.1 Dollars,\\\\Probability of Winning the 40 Dollar Prize - 1 / 100,\\\\[/tex]

[tex]1 / 100 * 40,\\" Expected Payoff " - 0.4 Dollars,\\\\Conclusion ; " Expected Payoff " = 1.5 + 1.3 + 1.1 + 0.4 = 4.30 Dollars[/tex]

The height of trapezoid VWXZ is 8(square 3) units. The upper base,VW, measures 10 units. Use the 30°-60°-90° triangle theorem to find the length of YX.

What is the length of the lower base, ZX?

Step-by-step explanation:

VW = 10units

WY = 8√3

XY = ?

ZX = ?

Find attached the diagram obtained from the information (1st image).

To determine XY, we would apply the tangent ratio.

Tan 60 = opposite/adjacent

Tan60 = (8√3)/XY

XY = (8√3)/ Tan60

In a 30°-60°-90° triangle theorem:

Find attached the diagram (2nd image)

Tan 60 = opposite/adjacent

Tan 60 = √3/1

Tan60= √3

XY = (8√3)/ Tan60

XY = (8√3)/√3

XY = 8units

ZX = ZY + XY

VW = ZY = 10units (the breadth of rectangle are equal)

ZX = 10 + 8

ZX = 18 units

Rent paid by Julie = (1/3) of 3000

                             [tex]=\frac{1}{3}*3000\\\\=1*1000[/tex]

                             = £ 1000

Remaining amount after paying rent = 3000 - 1000 = £ 2000

Expenses : Savings = 7 : 3

Total part  = 7 + 3 = 10

Saving part = 3/10

Amount saved = (3/10) of 2000

                        [tex]=\frac{3}{10}*2000\\\\=3*200[/tex]

                        = £ 600

Answer:

B

Step-by-step explanation:

one third of £3000 = £3000 ÷ 3 = £1000

£3000 - £1000 = £2000 ← amount left after paying rent

Add the parts of the ratio, 7 + 3 = 10 parts

Divide the amount left by 10 to find the value of one part of the ratio

£2000 ÷ 10 = £200 ← value of 1 part of the ratio, thus

3 × £200 = £600

Julie saves £600 each month

A coordinate plane with a line drawn passing through the points (0, 3) and (1,1). Which equation represents the graphed function? A coordinate plane y = –2x + 3 y = 2x + 3 y = x + 3 y = –x + 3

Answers

The slope is -2. (0,3) is (x1,y1) and (1,1) is (x2,y2) and so slope, m=y2-y1/x2-x1 so then it would be (1-3)/1-0 and that would be -2/1 which is -2. So then you would use point slope form so you would have y-y1=m(x-x1) and then you would go ahead and plug in your values so you get y-3=-2(x-0) adding 3 to both sides gives you y= -2x-0+3 which then simplifies to y=-2x+3 so your answer would be y=-2x+3

Answer:

the answer is A. y=-2x+3

You are in the process of making ice cream. The recipe says heat all ingredients to 50C and cools it for 5 hours in a freezer. If the cooling rate of the freezer is 12C per hour. What will be the temperature of the mixture after 5 hours?

Answers

Answer:

-10C

Step-by-step explanation;

The mixture is 50C and the freezer cools at 12C per hour which means in 5 hours the temperature of the mixture would have decreased by 60C because 12C * 5 hrs is 60C. You then do the math;

50C - 60C = -10C
