One jar holds 40 purple marbles and 5 black marbles. A second jar holds 90 orange marbles and 10 black marbles. What is the probability that a black marble will be drawn from both jars?
Answer:
1/90Step-by-step explanation:
The first jar holds 45 marbles and 5 of them are black.
The second jar holds 100 marbles and 10 of them are black.
Required probability:
P(b,b) = 5/45*10/100 = 1/9*1/10 = 1/90Now we have to find,
The probability that a black marble will be drawn from both jars.
The given information is,
→ 1st jar contains/holds 45 marbles.
→ 5 of the marbles are black.
→ 2nd jar contains/holds 100 marbles.
→ 10 of the marbles are are black.
Then the probability will be,
→ P(b,b)
→ (5/45) × (10/100)
→ (1/9) × (1/10)
→ 1/90
Thus, required probability is 1/90.

If a coin is tossed 55 times, and then a standard six-sided die is rolled 22 times, and finally a group of five cards are drawn from a standard deck of 5252 cards without replacement, how many different outcomes are possible
Answer:
2,994,001,920 different outcomes are possible.
Step-by-step explanation:
The coin, the die and the cards are independent events, so the fundamental counting principle is used.
Also, the order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
Combinations formula:
[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]
Coin:
Tossed 5 times, each toss 2 possible outcomes, so:
[tex]2^5 = 32[/tex]
32 possible outcomes.
Die:
Tossed 2 times, each toss with 6 possible outcomes, so:
[tex]6^2 = 36[/tex]
36 possible outcomes.
Cards:
Chosen without replacement, so the combinations formula is used, 5 from a set of 52. So
[tex]C_{52,5} = \frac{52!}{5!47!} = 2598960 [/tex]
How many different outcomes are possible?
Using the fundamental counting principle:
[tex]T = 32*36*2598960 = 2994001920[/tex]
2,994,001,920 different outcomes are possible.

For a hypothesis test of the claim that the mean amount of sleep for adults is less than 6 hours, technology output shows that the hypothesis test has power of 0.4272 of supporting the claim that μ<6 hours of sleep when the actual population mean is 4.0 hours of sleep. Interpret this value of the power, then identify the value of β and interpret that value.
Answer:
#[tex]\beta=0.5492[/tex]
#This Value of [tex]\beta[/tex] goes to indicate that there is greater [tex]50\%[/tex] probability that [tex]\mu<8[/tex] will not be acknowledged at [tex]\mu =5[/tex]
Step-by-step explanation:
From the question we are told that:
Amount of sleep for adults [tex]X=P(< 6)[/tex]
Hypothesis test has power [tex]p=0.4272[/tex]
Mean [tex]\=x =4hours[/tex]
Generally the equation for [tex]\beta[/tex] is mathematically given by
[tex]\beta=1-P[/tex]
[tex]\beta=1-0.4508[/tex]
[tex]\beta=0.5492[/tex]
Therefore
This Value of [tex]\beta[/tex] goes to indicate that there is greater [tex]50\%[/tex] probability that [tex]\mu<8[/tex] will not be acknowledged at [tex]\mu =5[/tex]
simplify (q and (-q or p)) or (p and -(q and p))
Step-by-step explanation:
(q and (not q or p)) = (q and not q) or (q and p) = false or q and p = q and p
(p and not (q and p)) = (p and (not q or not p)) =
= (p and not q) or (p and not p) = (p and not q) or false =
= p and not q
so, we have in total
(q and p) or (p and not q) = (p and q) or (p and not q).
this is p, because if p=false both brackets are false and therefore the whole expression is false. and if p=true, then one of the 2 brackets must be true, which makes the whole expression true.
what it the value of m when (2m+8)° and the other angle 24°
Answer:
m = 74
Step-by-step explanation:
2m+8 +24 has to = 180 because they form a line. So the equation would be 2m+32 = 180, so then 2m would equal 148, so m = 74.

Answer:
BAC
Step-by-step explanation:
The expression (3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to the expression A, expression (-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent to the expression C, and expression (12x² + 6x - 5) - (5x² + 8x - 12) is equivalent to the expression B.
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have a polynomial shown in the picture.
A = -7x² - 2x + 5
B = 7x² - 2x + 7
C = 7x² + 2x - 5
The expression is:
= (3x² - 6x + 11) - (10x² - 4x + 6)
= -7x² - 2x + 5
= A
= (-3x² - 5x - 3) - (-10x² - 7x + 2)
= 7x² + 2x - 5
= C
= (12x² + 6x - 5) - (5x² + 8x - 12)
= 7x² - 2x + 7
= B
Thus, the expression (3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to the expression A, expression (-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent to the expression C, and expression (12x² + 6x - 5) - (5x² + 8x - 12) is equivalent to the expression B.

The scores from the first test for students in my statistics class have an average of 70 and a standard deviation of 3. The scores from the second test has the same average and standard deviation as scores from the first test. The variance of the score from the second test given that the score in the first test is 65, is 2. Assume the scores of the students in the first test and second test are positively correlated and have a bivariate normal distribution. Calculate the average scores of the students in the second test given that the scores in the first test are 65.
Answer:
[tex]P(Y| X = 65)=66[/tex]
Step-by-step explanation:
From the question we are told that:
Mean[tex]\=x=70[/tex]
Standard Deviation [tex]\sigma=3[/tex]
Variance [tex]\sigma^2=2[/tex]
Generally the equation for Variance of Prediction is mathematically given by
[tex]\sigma_{p}^2=\sigma_{p}'^2*(1-r^2)[/tex]
Where
[tex]\sigma_{p}'^2=variance\ of\ predictor[/tex]
Therefore
[tex]2=3^2*(1-r^2)\\\\r=0.88[/tex]
Therefore
The Average score of student in 2nd test
[tex]P(Y| X = x) = \mu +\frac{p\sigma}{\sigma(x −\mu_X)}[/tex]
[tex]P(Y| X = 65) = 70 +0.88\frac{3}{3)}*(65-70)[/tex]
[tex]P(Y| X = 65)=66[/tex]

A survey of 200 school children classified students by gender and the number of times Sharky's Soda was purchased each month at school. Examine the chart below, where each respondent is classified according to the two criteria.
- What percentage of boys bought 1 Sharky's? What percentage of girls bought 2 or more Sharky's?
-What percentage of people bought no Sharky's?
-How would you characterize the relationship between boys that purchased Sharky's and the total of people buying 2 or more Sharky's Soda?
Answer:
15%
65%
7.5%
Step-by-step explanation:
1.) Percentage of boys who bought 1 Sharkys
Number of boys that bought 1 sharkys = 15
Total number of boys = 100
= 15 / 100 * 100% = 15%
2.)
Percentage of girls who bought 2 or more sharkys :
Number of girls who bought 2 or more sharkys
= 65
Total number of girls = 100
= 65 / 100 * 100% = 65%
3.)
Percentage of people who bought no sharkys
Number of people who bought no sharkys = 15
Total number of people = 200
15 / 200 * 100% = 7.5%

The degree of this expression 2x+3y=4
Answer:
1st degree
Step-by-step explanation:
You look at the largest exponet, right here, there are none so it would be 1st degree.
Answer:
1
Step-by-step explanation:
The degree of an expression with multiple exponents is the highest exponent in it. In this expression, there is no expression, so the answer will be 1 because there is no exponent and every variable and number has an invisible 1 as its exponent.

The population of the world in 1987 was 5 billion and the annual growth rate was estimated at 2 percent per year. Assuming that the world population follows an exponential growth model, find the projected world population in 2015
Answer:
The projected world population in 2015 was 8,705,121,030 people.
Step-by-step explanation:
Given that the population of the world in 1987 was 5 billion and the annual growth rate was estimated at 2 percent per year, assuming that the world population follows an exponential growth model, to find the projected world population in 2015 the following calculation must be performed :
5,000,000,000 x 1.02 ^ (2015-1987) = X
5,000,000,000 x 1.02 ^ 28 = X
5,000,000,000 x 1.741024 = X
8,705,121,030 = X
Therefore, the projected world population in 2015 was 8,705,121,030 people.
