Answer:
P(not getting a ticket for 2 days) = 0.49
Step-by-step explanation:
We are told that the probability of getting a ticket on any given day is 0.3.
Thus;
P(getting a ticket a day) = 0.3
This means that;
P(not getting a ticket a day) = 1 - 0.3 = 0.7
Now, 0.7 is probability of not getting a ticket for 1 day. Since each day's outcome is independent of the previous day's outcome, it means that for n days, probability of not getting a ticket for n days will be;
P(not getting a ticket for n days) = 0.7ⁿ
For 2 days, its = 0.7² = 0.49
Thus;
P(not getting a ticket for 2 days) = 0.49
In a certain state's lottery, 45 balls numbered 1 through 45 are placed in a machine and eight of them are drawn at random. If the eight numbers drawn match the numbers that a player had chosen, the player wins $1,000,000. In this lottery, the order in which the numbers are drawn does not matter.
Compute the probability that you win the million-dollar prize if you purchase a single lottery ticket. Write your answer as a reduced fraction.

Answer: $
A single lottery ticket costs $2. Compute the Expected Value, to you, if you purchase 10,000 lottery tickets. Round your answer to the nearest dollar.
Answer: $
Step-by-step explanation:
The order of the numbers doesn't matter, so we'll use combinations instead of permutations. The number of combinations is:
₄₅C₈ = 215,553,195
So the probability of a ticket having the winning combination is 1 / 215,553,195.
The expected value to the state is:
E(X) = 10,000 (1) ($2) + 10,000 (1 / 215,553,195) (-$1,000,000)
E(X) = $19954
The expected value to you is:
E(X) = 10,000 (1) (-$2) + 10,000 (1 / 215,553,195) ($1,000,000)
E(X) = -$19954
Sending text messages from Katrina's cell phone costs $0.18 per text message . From last monthshe has a credit on her bil for $9.00How much more money will she need to pay for text messages this month if she has sent 204 messages?
A. $ 29.22
B. $25.72
C.$36.72
D. $27.72
Answer:
D. $27.72
Step-by-step explanation:
Calculation for How much more money will she need to pay for text messages
First step is to the Total cost of sending 204 messages
Total cost=204 messages* $0.18 per text message
Total cost =$36.72
Last step is to compute for How much more money will she need to pay for text messages
Amount to be paid =$36.72-$9.00
Amount to be paid=$27.72
Therefore How much more money will she need to pay for text messages will be $27.72

Big chickens: The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1387 grams and standard deviation 192 grams. Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1150 and 1308 grams? (b) What is the probability that a randomly selected broiler weighs more than 1510 grams? (c) Is it unusual for a broiler to weigh more than 1610 grams? Round the answers to at least four decimal places.
Answer:
a) 0.2318
b) 0.2609
c) No it is not unusual for a broiler to weigh more than 1610 grams
Step-by-step explanation:
We solve using z score formula
z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean 1387 grams and standard deviation 192 grams. Use the TI-84 Plus calculator to answer the following.
(a) What proportion of broilers weigh between 1150 and 1308 grams?
For 1150 grams
z = 1150 - 1387/192
= -1.23438
Probability value from Z-Table:
P(x = 1150) = 0.10853
For 1308 grams
z = 1308 - 1387/192
= -0.41146
Probability value from Z-Table:
P(x = 1308) = 0.34037
Proportion of broilers weigh between 1150 and 1308 grams is:
P(x = 1308) - P(x = 1150)
0.34037 - 0.10853
= 0.23184
≈ 0.2318
(b) What is the probability that a randomly selected broiler weighs more than 1510 grams?
1510 - 1387/192
= 0.64063
Probabilty value from Z-Table:
P(x<1510) = 0.73912
P(x>1510) = 1 - P(x<1510) = 0.26088
≈ 0.2609
(c) Is it unusual for a broiler to weigh more than 1610 grams?
1610- 1387/192
= 1.16146
Probability value from Z-Table:
P(x<1610) = 0.87727
P(x>1610) = 1 - P(x<1610) = 0.12273
≈ 0.1227
No it is not unusual for a broiler to weigh more than 1610 grams

Kumar is opening a lemonade stand. He spent $4.50 to build the stand and $2.50 for lemons and sugar. He has enough ingredients to make 20 glasses of lemonade. How much should he charge for one glass of lemonade to cover his expenses and make $10 in profit?
Round to the nearest cent.
Timed test
Answer:
profit = revenue - cost
10 = 20x - (4.5 + 2.5)
10 = 20x - 7
10 + 7 = 20x
17 = 20x
17/20 = x
0.85 = x
check...
profit = revenue - cost
10 = 20(0.85) - 7
10 = 17 - 7
10 = 10 (correct)
so he would have to sell each cup at 0.85 ccents to make a profit of $ 10

rewrite the fraction as a decimal 69/4
Answer:
17.25
Step-by-step explanation:
69 ÷ 4 = 17.25I hope this helps!
The solution is: the fraction 69/4 as a decimal is 17.25.
we have,
the fraction is 69/4
now, we get,
69 ÷ 4 = 17.25
i.e. we get,
we have to find how many times 4 would go into 69 by dividing
The quotient is 17 and 4 x 17= 68
Left is 1 which still has to be divided by 4 1/4= 0.25
so, we get,
17+0.25
=17.25
Hence, The solution is: the fraction 69/4 as a decimal is 17.25.

A biker cycles 9 miles in 2/3 of an hour.
The distance here varies directly with time. What is the constant of variation? (It is the hikers’ rate .)
Answer:
this is for you RSM people.
1 hour=13.5
2 hours=27
3 hours=40.5
3.5 hours=47.25
Step-by-step explanation:
The constant variation of the biker is the speed of the biker, Hence, the constant variation is 13.5 mph
Giveb the Parameters :
Distance biked = 9 miles Time taken = 2/3 hoursRecall :
Speed = distance / timeSpeed = 9 ÷ 2/3
Speed = 9 × 3/2
Speed = 27/2 = 13.5 miles per hour.
Therefore, the constant variation is 13.5 mph.

How many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% w/w of salicylic acid?
Answer:
4.79 g
Step-by-step explanation:
mass of salicylic acid = ??
Mass of polyethylene = 75 g
% w/w concentration = 6% w/w
Let the mass of salicylic acid be x
Let the mass of solution = 75 + x
from
% w/w = mass of solute/ mass of solution * 100
Hence concentration of salicylic is;
6 = (x/75 + x) * 100
6/100 = x/75 + x
0.06 (75 + x) = x
4.5 + 0.06x =x
4.5 = x-0.06x
x = 4.5/0.94
x= 4.79 g
4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.
To determine how many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid, the following calculation must be performed:
100 - 6 = 94 94 = 75 6 = X 6 x 75/94 = X 450/94 = X 4.7872 = X
Therefore, 4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.
