Answers
Answer:
(1) Correct option (A).
(2) The probability that Aadi will get Tails is 0.40.
Step-by-step explanation:
The information provided is:
Eric throws a biased coin 10 times. He gets 3 tails.Sue throw the same coin 50 times. She gets 20 tails.The probability of tail in both cases is:
\(P(T|E)=\frac{3}{10}=0.30\)
\(P(T|S)=\frac{20}{50}=0.40\)
Here,
P (T|E) implies the probability of tail in case of Eric's experiment.
P (T|S) implies the probability of tail in case of Sue's experiment.
(1)
Now, it is given that Aadi is going to throw the coin once.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
In this case we need to compute the probability of Aadi getting Tails in a single toss.
As Sue uses a larger number of trials in the experiment, i.e. n = 50 > 30 times, according to the Central limit theorem, Sue's estimate is best because she throws it .
Thus, the correct option is (A).
(2)
As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:
\(P(\text{Aadi will get Tails})=P(T|A)\)
\(=P(T|S)\\\\=0.40\)
Thus, the probability that Aadi will get Tails is 0.40.
Answer:
The correct answer is C and 23/60
Step-by-step explanation:
Sue's estimate is best because she throws it more times than Eric.
This is because the more you throw a coin the more reliable the results will be compared to data from a coin that has been thrown less, therefore the answer is C.
For the second half you need to add the number of tails together to get you numerator and then add the amount of times the coin was thrown to get your denominator, (giving you 23/60)
Hope this helped :)

What is the greatest number less than 400 such that 4 is the greatest common divisor of the number and 24?
Answers
Answer:
its simple greatest number less that 400 is 399
Answer:
388
Step-by-step explanation:
Definition from Wikipedia
In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as gcd(x,y) . For example, the GCD of 8 and 12 is 4, that is, gcd(8,4)=4 (https://en.wikipedia.org/wiki/Greatest_common_divisor)
Methodology to find greatest common denominator(factor) for 2 numbers
Write down the divisors of both numbersCollect the common divisors of both termsChoose the largest divisor from the above termsThe divisors of 24 are 1, 2, 3, 4, 6, 8, 12, 24Since the number is less than 400, it must be 4 x D where D < 100Let's try 4 x 99 = 396. Divisors are 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396. gcd(24, 396) = 12.Try D = 98 ==> 4 x 98 = 392 with divisors 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392. gcd(24, 392) = 8Try D = 97 ==> 4 x 97 = 388. Divisors of 388 are 1, 2, 4, 97, 194, 388 gcd(4, 388) = 4Note that even though I have listed all divisors of the higher number, you don't have to compute all divisors. You can stop figuring out the divisors once the larger number is divisible by the number that is higher than 4 but slosest to i. For example, in the case of 396, I would stop computing as soon as I found it is divisible by 6

100 points and brainliest if answered quickly!!!! Nick is investigating cell phone use in his hometown. So far, he has found that the residents used their cell phones for 217,470 minutes last year. This year, they used their cell phones for a total of 434,940 minutes. What is the percent of increase in annual usage?
Answers
To calculate the percent increase in annual usage of cell phones, we can use the following formula:
Percent increase = [(new value - original value) / original value] x 100
where the new value is the current year’s usage and the original value is last year’s usage.
In this case, Nick found that residents used their cell phones for 217,470 minutes last year and 434,940 minutes this year. So we can plug these values into the formula:
Percent increase = [(434940 - 217470) / 217470] x 100
Percent increase = 100%
Therefore, there was a 100% increase in annual usage of cell phones.
I hope that helps! Let me know if you have any other questions.

Answer:
2/3(3/4x-3/2) = 1/2x-1
(2x+1) - (x+3/2) = x - 1/2
Step-by-step explanation:
1) Distribute 2/3 to both 3/4x and -3/2
2/3(3/4x) = 6/12x which can be simplified as 1/2x
2/3(-3/2) = -6/6 which simplifies to -1
2/3(3/4x-3/2) = 1/2x-1
2) (2x+1) - (x+3/2) combine like terms
2x-x = x
1 - 3/2= 1- 1 1/2 ( change 3/2 into an improper fraction. 2 goes into 3 one time with one left over. Place the “leftover” back on top of the original denominator of 2)
1- 1 1/2 = -1/2, so
(2x+1) - (x+3/2) = x - 1/2

Step-by-step explanation:
Write a system of equations to represent the problem. Let x represent the cost of a binder, and let y represent the cost of a notebook.
Grace buys 4 binders and 7 notebooks for $26.50 total, so the equation 4x+7y=26.50 represents how much Grace spends.
Grace's friend buys 3 binders and 6 notebooks for $21.00 total, so the equation 3x+6y=21 represents how much her friend spends.
You can use this system of equations to find how much money Grace and her friend spend on notebooks:
4x+7y=26.50
3x+6y=21
Next, find how much Grace and her friend spent on notebooks. Start by finding the cost of one notebook. Use elimination to solve for y. .
3(4x+7y)=3(26.50)

12x+21y = 79.50

Emily noticed that on halloween, her child got three basic types of candy: chocolate, gummy, and hard candy. She has 15 more hard candies that chocolate, and 5 less than twice the amount for gummy candy than chocolate. if she had a total of 178 pieces of candy, how many of each type did she get?
Answers
Answer: gotta scroll down sry
Step-by-step explanation:
First set up equations with variables that show the information you have:
c = chocolate // g = gummy // h = hard candy
178 = c + g + h
h = c + 15
g = 2c - 5
Then, solve all the equations for a number:
178 = c + g + h (leave as is)
15 = -c + h (subtract 'c' from the original equation's right side and switch the sides of the equation)
-5 = -2c + g (subtract '2c' from the original equation's right side and switch the side of the equation)
Then, line up all the variables and subtract the top equation by the lower two:
178 = c + g + h
15 = -c + 0g + h
-5 = -2c + g + 0h
---------------------------
168 = 4c + 0g + 0h >>>> 168 = 4c
Solve for 'c' and plug it into the other equations to find 'h' and 'g':
168/4 = 4c/4
42 = c
15 = -(42) + h -5 = -2(42) +g
57 = h 79 = g
Add all the numbers together to double-check:
42 + 57 + 79 = 178
chocolates = 42
gummies = 79
hard candies = 57

Sanjay went blueberry picking along a 3-mile walking path. He picked blueberries steadily along the walk. When he was finished, he had collected 50 ounces of blueberries.
How many ounces of blueberries did Sanjay pick each mile?
Write your answer as a proper fraction or mixed number.
Answers
Answer:
16 2/3 per a mile
Step-by-step explanation:
50 ounces of blueberries/3 miles = 16.666 repeated
16.666 repeated = 16 2/3 ounces/mile
Answer: Sanjay picked 16.66 ounces each mile
Step-by-step explanation:
For this exercise let "x" represents the amount of ounces of blueberries that Sanjay picked each mile, along the 3-mile walking path.
According to the information given in the exercise, you know that Sanjay picked a total amount of 50 ounces of blueberries along the walking path.
Then, knowing that the length of that walking path is 3 miles, you can set up the following proportion:
\(\frac{3}{50} = \frac{1}{x}\)
Now, the next step is to solve for "x" in order to find its value.
You get that this is:
\((x)(\frac{3}{50} )=1\\\\x=(1)(\frac{3}{50} )\\\\x=16.66\)
Therefore, knowing the value of "x", you can conclude that Sanjay picked 16.66 ounces of blueberries each mile.
16.66 = 16 2/3
