Answer:
Probability [choosing a red marble] = 3 / 11
Step-by-step explanation:
Given:
Number of red marble in jar = 6
Number of green marble in jar = 5
Number of blue marble in jar = 8
Number of yellow marble in jar = 3
Find:
Probability [choosing a red marble]
Computation:
Total number of marble = 6 + 5 + 8 + 3
Total number of marble = 22 marble
Probability of an outcome = Favorable outcome / Number of total outcomes
Probability [choosing a red marble] = Number of red marble in jar / Total number of marble
Probability [choosing a red marble] = 6 / 22
Probability [choosing a red marble] = 3 / 11

What is the P(A and B) given that P(A) = 0.53, P(B) = 0.39, and P(A or B) = 0.48
Answer:
P(A and B) = 0.44
Step-by-step explanation:
Venn probabilities:
Suppose that we have two events, A and B. The probability of A and B is:
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
In which [tex]P(A \cup B)[/tex] is P(A or B).
In this question:
[tex]P(A) = 0.53, P(B) = 0.39, P(A \cup B) = 0.48[/tex]
Then
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.53 + 0.39 - 0.48 = 0.44[/tex]
So
P(A and B) = 0.44

Of 10 test scores, eight are less than or equal to 82. What is the percentile rank of a test score of 82?
Answer:
80%
Step-by-step explanation:
Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%
Percentile = (8 / 10) * 100%
= 0.8 * 100%
= 80%

Miguel draws a square on a coordinate plane. One vertex is located at (5,4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex. A. (5,1) B. (5,7) C. (7,8) D. (2,6) E. (2,1)
I will give brainliest if you answer both questions!
Answer:
A, B, and E.
Step-by-step explanation:
We know that one vertex is at (5, 4), and each side of our square is 3 units long.
Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3 units (if those vertexes are connected by the diagonal of the square).
Also remember that the distance between two points (a, b) and (b, c) is:
distance = √( (a - c)^2 + (b - d)^2)
So we need to find the distance between our point and all the ones given in the options:
A) the distance between (5, 4) and (5, 1) is:
distance = √( (5 - 5)^2 + (4 - 1)^2) = 3
Then point (5, 1) can be a vertex.
B) The distance between (5, 4) and (5, 7) is:
distance = √( (5 - 5)^2 + (4 - 7)^2) = 3
Then (5, 7) can be a vertex.
C) The distance between (5, 4) and (7, 8) is:
distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20
Point (7, 8) can not be a vertex.
D) The distance between (5, 4) and (2, 6) is:
distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13
Point (2, 6) can not be a vertex.
E) The distance between (5, 4) and (2, 1) is:
distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3
Then point (2, 1) can be a vertex.

Answer:
The answer to the first question is B.
The answer to the second question is C.
Answer:
3: B or 1/4
4: C or 15%
Step-by-step explanation:
3: There are 8 letters in Geometry and 2 E's in the word so it would be 2/8, but then you would simplify it and you will get 1/4.
4: 0.85 in a percentage is 85%. So 85% that WILL rain.
100 - 85 = 15, thus there is a 15% probability it will NOT rain.

Winston typically spends about $200 per year playing the lottery. If he took that same
amount of money, for 30 years, and invested it in an index fund earning an average of
6%, approximately how much money would Winston have?
A. More than $12,000, because the investment will grow faster over time as the interest
compounds.
B. Less than $6000, because inflation would make his money less valuable.
C. Exactly $6000.
D. Approximately $6360, because he earns almost $400 in interest.
Answer:
point!!!!!!!
Step-by-step explanation:
Winston would have A. More than $12,000, because the investment will grow faster over time as the interest compounds.
If Winston invested $200 every year at 6% for 30 years, the $200 would be an annuity and the future value of an Annuity is calculated as:
= Annuity x ( (1 + rate) ^ number of years - 1) / rate
= 200 x ( ( 1 + 6%) ³⁰ - 1) / 6%
= $15,811.64
Winston would have $15,811.64 which is more than $12,000 because compounded interest makes investments grow faster.

A simple random sample of electronic components wil be selected to test for the mean lifetime in hours. Assume that component lifetimes are normally distributed with population standard deviation of 16 hours. How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours
Answer:
189 components must be sampled.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.
This means that [tex]\sigma = 16[/tex]
How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?
n components must be sampled.
n is found when M = 3. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]3 = 2.575\frac{16}{\sqrt{n}}[/tex]
[tex]3\sqrt{n} = 2.575*16[/tex]
[tex]\sqrt{n} = \frac{2.575*16}{3}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575*16}{3})^2[/tex]
[tex]n = 188.6[/tex]
Rounding up:
189 components must be sampled.

The General Social Survey collects data on demographics, education, and work, among many other characteristics of US residents. From the 505 sampled US residents with a college degree, the average number of hours worked each week was 41.8 hours with a standard deviation of 15.1 hours. For those 667 residents without a degree, the mean was 39.4 hours with a standard deviation of 15.1 hours.
Required:
Conduct a hypothesis test at significance level 0.05.
Answer:
We reject H0 ; We conclude that mean number of resident with a college degree is greater than those without degree.
Step-by-step explanation:
H0 : μ1 = μ2
H1 : μ1 > μ2
n1 = 505
s1 = 41.8
x1 = 15.1
n2 = 667
s2 = 39.4
x2 = 15.1
df = smaller, n - 1 ; 505 - 1= 504
Test statistic :
(x1 - x2) / √((s1²/n1) + (s2²/n2))
(41.8 - 39.4) /√((15.1^2 / 505) + (15.1^2 / 667))
2.4 / 0.8907014
Test statistic = 2.6945057
Using the Pvalue calculator from test statistic :
df = 504 ; α = 0.05
Pvalue = 0.0036
Decision region : If Pvalue < α ; Reject H0
0.0036 < 0.05 ; We reject H0 ; We conclude that mean number of resident with a college degree is greater than those without degree.
