Andre is waiting for the school bus. He knows that 2 out of 6 cars in his town are white. He wants to determine the probability that at least two white cars drive by in a row. He uses a number cube as a simulation. He lets the numbers 1 and 2 represent a white car and lets all other numbers represent a car that is not white. He rolls the number cube 6 times and records the outcomes in the table below.
Trial Number Outcome
1 4, 3, 6, 1, 2, 4
2 5, 5, 1, 3, 6, 6
3 2, 5, 4, 4, 1, 3
4 6, 1, 5, 6, 6, 4
5 2, 1, 2, 6, 4, 5
6 3, 3, 1, 4, 2, 6
7 1, 5, 6, 2, 2, 3
8 3, 6, 4, 3, 4, 4
9 1, 1, 2, 1, 5, 6
10 4, 3, 3, 1, 5, 2
Based on the data, what is the probability that at least 2 white cars drive by in a row?

Once an answer is submitted, you will be unable to return to this part.Find the sum and product of each of these pairs of numbers. Express your answers as base 3 expansions.The sum of the numbers (20001)3 and (1112)3 is ( )3 and their product is ( )3.
Answers
Answer:
The answer is " [tex](21120)_3[/tex] and [tex](100011112)_3[/tex]"
Step-by-step explanation:
Calculating the sum:
[tex]a= (20001)_3 \\\\b= (1112)_3[/tex]
[tex]\to a+b = 20001+1112[/tex] // 163+41=204
[tex]=(21120)_3[/tex]
Explanation:
In the addition, first convert the given value (a,b) into decimal point that is (163, 41) and by adding its value is equal to (204) and after convert its value is equal to [tex](21120)_3[/tex].
Calculating the product:
[tex]a= (20001)_3 \\\\b= (1112)_3[/tex]
[tex]\to a*b = 20001*1112[/tex] // 163 *41=6,683
[tex]=(100011112)_3[/tex]
Explanation:
In the product calculation we convert the given value (a,b) into decimal point that is (163, 41) and multiplting its value which is equal to (6,683) and after convert its value is equal to [tex](100011112)_3[/tex].

a) Skewed leftb) Skewed rightc) Normally distributed (symmetrical)d) Normally distributed (symmetrical)==============================================================
Explanations:
a) It's a very unfortunate part of life that everyone dies, and some do earlier than others. In general and on a grand scale of things, the older generations tend to die more frequently compared to the younger generations. In other words, an 90 year old man is more likely to die than say a 20 year old man. This is assuming that they both live in the same environment with other factors held constant as well. Because the older generation dies more frequently, this means we have the main cluster to the right (where the ages are older) and a long tail stretching to the left. The tail is the set of outliers of people who died at a fairly young age. Again, I'm not saying that young people don't die, but I'm saying that they don't die as much compared to older people. This tail on the left tells us we have negatively skewed data.b) Most cars are priced low so that people can afford them. So the main cluster is to the left while we have outliers to the right. The outliers to the right represent very expensive luxury cars. The outliers on the right side pull on the right tail to make it skewed to the right. We consider this positively skewed. In contrast, the one for part (a) was negatively skewed. Think of the positive and negative directions on the x axis to help figure out which direction things are being skewed in.c) Some people have a lot of pets, while others have few or none at all. In the middle is some average number where the highest peak is located. The distribution is fairly normal as with anything scattered about on average.d) Similar to part (c). There are some very short women, and some are very tall, but the majority are within some range of the average height. Doing a dot plot or a histogram of the distribution help leads to an approximately normal distribution, which is symmetric.Eric has $25 to purchase magazines and to pay for his lunch. Each
magazine costs $4 and his lunch costs $15. Which inequality can be used
to determine how many magazines, m, Eric can buy?
A. 4m - 15 > 25
B. 4m - 15 < 25
C. 4m + 15 > 25
D. 4m + 15 = 25
Answers
Answer:
B
Step-by-step explanation:
The maximum amount Eric can spend on magazines is $25 less the cost of lunch, $15.
The appropriate inequality sign would be less than since he cannot spend more than $25.
Also, the amount he can spend on magazines would be what is left after paying for lunch.
So the correct inequality is 4m - 15 < 25

Answers
Answer:
A. 0.2734 = 27.34% probability that there are an equal number of boys and girls
B. 0.2753 = 27.53% probability that she’ll answer exactly 5 questions correctly
Step-by-step explanation:
In each of these questions, the binomial probability distribution is used.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
A.The Murray family has produced 8 children.
What is the probability that there are an equal number of boys and girls?
8 children means that [tex]n = 8[/tex]
Each children is equally as likely to be a boy or a girl, which means that [tex]p = 0.5[/tex]
This probability is P(X = 4). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{8,4}.(0.5)^{4}.(0.5)^{4} = 0.2734[/tex]
0.2734 = 27.34% probability that there are an equal number of boys and girls
B.Margie has the uncanny ability of being able to guess the correct answer to TRUE/FALSE questions with an 80% accuracy rate. Tomorrow’s test has 7 questions on it and she needs to answer 5 questions correctly in order to make the Honor Roll. If she guesses on every question, what is the probability that she’ll answer exactly 5 questions correctly?
80% accurracy rate means that [tex]p = 0.8[/tex]
7 questions means that [tex]n = 7[/tex]
The probability is P(X = 5). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{7,5}.(0.8)^{5}.(0.2)^{2} = 0.2753[/tex]
0.2753 = 27.53% probability that she’ll answer exactly 5 questions correctly

Answer:
The number is 4
Step-by-step explanation:
We set up the equation given the conditions listed. Since it says 5 times the difference between a number and 7, we can use x as a placeholder for the number.
(x-7) is the difference between the number and 7. The question asks for 5 times that difference thus we multiply the entire thing by 5 giving us 5(x-7. The question says that it all equals -15 so we set that expression equal to -15.
Thus we get the equation and solve:
5(x-7)= -15 (distributive property)
5x-35= -15 (add 35 to both sides)
5x=20 (divide by 5)
x=4; so the number is 4
