A single coin is flipped four times. A) Use an organizational strategy to construct the sample space for this situation. B) How many different outcomes are possible?

Answers

Step-by-step explanation:

- A single coin is known to have 2 sides (The head H and the tail T).

The total number of sample space for n number of coins is expressed as 2ⁿ where

n is the total number of coins flipped.

If a single coin is flipped four times, the total outcome will be expressed as;

2⁴ = 16

Hence there are 16 different possible outcomes.

- To construct the sample space (the 16 possible outcomes)

For one flipped coin, the sample space is represented by the set S₁

S₁ = {H, T}

H is Head

T is Tail

For two flipped coin, the sample space is represented by the set S₂

S₂ = S₁×S₁

S₂ = {H, T}×{H,T}

S₂ ={HH, HT, TH, TT}

For three flipped coin, the sample space is represented by the set S₃

S₃ = S₂×S₁

S₃ = {HH, HT, TH, TT}×{H,T}

S₃ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

For four flipped coin, the sample space is represented by the set S₄

S₄ = S₃×S₁

S₄ = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}×{H,T}

S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT}

Hence the sample space for a single coin flipped 4times is given by the set;

S₄ ={HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT} where;

n(S₄) = 16

According to a survey conducted by the Texas Free Press, 125 out of 500 people do not have internet access at their homes. What percent of the people surveyed do have internet access at their homes?

Answers

75%
500-125 is 375
375/500 gives 3/4 which is .75
move the decimal over to the right twice to get 75%

125 do not

375 have

500 is the total

500-125 =375

375/500

500 divided by 375 = 0.75

A house as purchases for $ 6780000.
a- Write the purchase price in million?

b- Write the purchase price in millions nearest to an integer.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

As there are 1000000 units in 1 million

i.e.

1 million = 1000000 units

A house as purchases for $6780000.

Thus, the purchase price in million will be:

6780000/1000000 = 6.78 million

purchase price in millions nearest to an integer

As the number we are rounding is followed by 7, so will be round the number up.

Therefore,

$6780000 rounded to the nearest million = $7,000,000

Ben has a collection of baseball cards. He has a total of 1,600 cards. Of the baseball cards, 35% are dated before 1980, 25% are dated from 1980 to 2000, and
the rest are dated after 2000.
How many baseball cards in Ben's collection are dated after 2000?

Answers

Answer:

640 cards

Step-by-step explanation:

If the rest are dated after 2000, that means that 40% are dated after 2000, since 25% + 35% = 60%

To find how many are dated after 2000, multiply 1,600 by 0.4:

1,600(0.6) = 640

So, 640 of the baseball cards are dated after 2000

Yolanda has a 1/6 -cup ladle that she uses to pour gravy over potatoes. She uses one full ladle for each serving of potatoes. Yolanda has 6 cups of gravy. How many servings of potatoes can she make?

Answers

Answer: For 6 cups of gravy, Yolanda will have 36 servings of potatoes

Step-by-step explanation:

Step 1

Since Yolanda has a 1/6-cup of ladle for one full serving

Then for every serving the 1/6- cup ladle is used and can be expressed as

1 serving =1/6-cup of ladle

Step 2--- Solving

Serving of potatoes for 1 cup is

1 serving =1/6 cup of ladle

?? servings=1 cup of ladle ( cross multiply)

= 1 x 6/1 = 6 servings

Therefore 6 cups of gravy = 6 servings x 6 = 36 servings of potatoes
