Step-by-step explanation:
A bag contains 10 marbles,7 of which are black and 3 are red.three marbles are drawn at one after the other.find the probability of choosing at most two black marbles.
==========================================================
Explanation:
We have these four cases or possible outcomes
Case 1) We select 0 black marbles and 3 red marbles.Case 2) We select 1 black marble and 2 red marbles.Case 3) We select 2 black marbles and 1 red marble.Case 4) We select 3 black marbles and 0 red marbles.Let's calculate the probability for case 4.
There are 7 black marbles out of 10 total. The probability of picking black is 7/10. If no replacement is made, then 6/9 is the probability of picking black again (subtract 1 from the numerator and denominator separately). Finally, 5/8 is the probability of getting black a third time.
The probability of getting 3 black marbles in a row is
(7/10)*(6/9)*(5/8) = (7*6*5)/(10*9*8) = 210/720 = 7/24.
That fraction 7/24 means that if you had 24 chances, then you expect about 7 of them will lead to getting three black marbles in a row (aka case 4). Therefore, 24-7 = 17 occurrences are expected where we get cases 1 through 3 occur in some fashion (pick one case only).
Notice how cases 1 through 3 encapsulate the phrasing "at most 2 black marbles" which is another way of saying "2 black marbles is the highest we can go".
So that's why the answer is 17/24.

Lines 3x-2y+7=0 and 6x+ay-18=0 is perpendicular. What is the value of a?
1/9
9
-9
-1/9
Pls answer
Answer:
[tex]\boxed{\sf a = 9 }[/tex]
Step-by-step explanation:
Two lines are given to us which are perpendicular to each other and we need to find out the value of a . The given equations are ,
[tex]\sf\longrightarrow 3x - 2y +7=0 [/tex]
[tex]\sf\longrightarrow 6x +ay -18 = 0 [/tex]
Step 1 : Convert the equations in slope intercept form of the line .
[tex]\sf\longrightarrow y = \dfrac{3x}{2} +\dfrac{ 7 }{2}[/tex]
and ,
[tex]\sf\longrightarrow y = -\dfrac{6x }{a}+\dfrac{18}{a} [/tex]
Step 2: Find the slope of the lines :-
Now we know that the product of slope of two perpendicular lines is -1. Therefore , from Slope Intercept Form of the line we can say that the slope of first line is ,
[tex]\sf\longrightarrow Slope_1 = \dfrac{3}{2} [/tex]
And the slope of the second line is ,
[tex]\sf\longrightarrow Slope_2 =\dfrac{-6}{a} [/tex]
Step 3: Multiply the slopes :-
[tex]\sf\longrightarrow \dfrac{3}{2}\times \dfrac{-6}{a}= -1 [/tex]
Multiply ,
[tex]\sf\longrightarrow \dfrac{-9}{a}= -1[/tex]
Multiply both sides by a ,
[tex]\sf\longrightarrow (-1)a = -9 [/tex]
Divide both sides by -1 ,
[tex]\sf\longrightarrow \boxed{\blue{\sf a = 9 }} [/tex]
Hence the value of a is 9 .
how do i find upper and lower quartile
please help will give brainliest
Answer:
Step-by-step explanation:
Arrange the data set in ascending order. then find the median.
Data in ascending order:
2, 5 , 6 , 7 , 8 , 11 , 15
Median = 7
Lower quartile:
Then again find the median of the numbers from the first to the number before the median. This is the lower quartile.
2 , 5, 6
Median = 5 ----> this is the lower quartile.
Upper quartile:
Then again find the median of the numbers that comes after the median to the end of the data set. This is the upper quartile.
8 , 11 , 15
Median = 11 ------> is the upper quatile

[tex] {9}^{x} \times 16^{x } = 12[/tex]
9ˣ × 16ˣ = (9 × 16)ˣ = 144ˣ = 12
Since 12² = 144, it follows that x = 1/2.
That is,
144ˣ = 12
(12²)ˣ = 12
12²ˣ = 12
log₁₂(12²ˣ) = log₁₂(12)
2x log₁₂(12) = log₁₂(12)
2x = 1
x = 1/2
Jack can build 1/5 of a shed in the same time Kyle build 5/8 of a shed. How much of a shed will jack have built when Kyle has finished building 1 shed.
Answer:
Step-by-step explanation:
If Kyle can get 5/8 of a shed built in x amount of time, he can get 62.5% done; if Jack can get 1/5 of the shed built in the same time, he can 20% of it done. As a ratio:
[tex]\frac{Kyle}{Jack}:\frac{62.5}{20}[/tex] Kyle gets the whole thing done, 100% of the way, leaving Jack lagging behind at a somewhat lower percentage of the work being done.
[tex]\frac{Kyle}{Jack}:\frac{62.5}{20}=\frac{100}{x}[/tex] and cross multiply to solve for the percentage of the shed built by Jack by the time Kyle gets it completed:
62.5x = 2000 so
x = 32%
When Kyle will complete the work the amount of the work done by Jack will be 32%.
What is an expression?Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
If Kyle can get 5/8 of a shed built in x amount of time, he can get 62.5% done; if Jack can get 1/5 of the shed built in the same time, he can 20% of it done. As a ratio:
Jack falls behind Kyle, completing only a small portion of the work, while Kyle completes the entire task and cross multiplies to solve for the percentage of the shed built by Jack by the time Kyle gets it completed:
Kyle / Jack ÷ 62.5 / 20 = 100 / x
62.5x = 2000 so
x = 32%
Therefore, when Kyle will complete the work the amount of the work done by Jack will be 32%.

The dimensions of a screen are 21 ft by 20 ft. Find the length of the diagonal .
Answer:
29 ft
Step-by-step explanation:
the screens have 90 degree angles so they form right triangles with the diagonal, so use Pythagorean theorem to solve for the diagonal
diagonal² = 21² +20² , square and square root both sides of the equation
diagonal = √441+400, add
diagonal = √841, square root

Did you know that all 50 states in the United States have some sort of state fair? Fairs and carnivals
include a variety of games of chance that aren't typically "fair." What does it mean for a game to be fair? In
this task, you'll analyze different scenarios to determine fairness. You will use probability and expected
value to make these determinations. You will also use these concepts to make decisions.
As you complete the assignment, keep this question in mind:
Tanya should play The second game to win more.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given, Tanya is considering playing a game at the fair. There are three different ones to choose from, and it costs $2 to play a game. The probabilities associated with the games are given in the table.
From the general formula of weighted possibility :
Total weighted possibility = Sum of the weighted probability of desired outcomes - the weighted possibility of undesired outcomes
In our case,
For first game
The sum of the weighted possibility of desired outcomes = 0.20*1 + 0.25 *4
The sum of the weighted possibility of desired outcomes = 1.20
the weighted possibility of undesired outcomes = 0.55 * 2 = 1.10
Thus,
Total weighted desired possibility = 1.20 - 1.10
Total weighted desired possibility = 0.10
For second game
The sum of the weighted possibility of desired outcomes =0.35*1 + 0.50 *4
The sum of the weighted possibility of desired outcomes = 2.35
the weighted possibility of undesired outcomes = 0.15 * 2 = 0.30
Thus,
Total weighted desired possibility = 2.35 - 0.30
Total weighted desired possibility = 2.05
For third game
The sum of the weighted possibility of desired outcomes = 0.60*1 + 0.20*4
The sum of the weighted possibility of desired outcomes = 1.40
the weighted possibility of undesired outcomes = 0.20 * 2 = 0.40
Thus,
Total weighted desired possibility =1.40 - 0.40
Total weighted desired possibility = 1
Therefore, Tanya should play The second game to win more.
