Answer:
Blue: 3/5
Red: 1/5
if the question is asking for the probability of if one marble you will pick out of bag is red OR blue, it will be 4/5
Step-by-step explanation:
add all the marbles together. 25 marbles.
so if there are 15 blue marbles, then there would be a 15 out of 25 chance you will get a blue marble. simplified is 3/5. same goes for the red marbles.

What is the slope of (6,-2) and (-3,1)
Answer:
slope = 1
Step-by-step explanation:
We have two points which are (6,-2) and (-3,1).
and we need to find slope
use the slope formula
m = ( y² - y1 ) / ( x² + x¹)
Where,
m is the slope( y² - y1 ) = ( 1 - 6 )( x² + x¹) = ( -3 -2)substitute the values
m = ( 1 - 6 ) / ( - 3 -2)
m = -5 / -5
divide we get
m = 1
Answer:
slope = - [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6-2) and (x₂, y₂ ) = (- 3, 1)
m = [tex]\frac{1-(-2)}{-3-6}[/tex] = [tex]\frac{1+2}{-9}[/tex] = [tex]\frac{3}{-9}[/tex] = - [tex]\frac{1}{3}[/tex]

Answer:
[tex]x=-5,\\y=\frac{13}{2}[/tex]
Step-by-step explanation:
[tex]\begin{cases}x+2y=8,\\x=-5\end{cases}[/tex]
Substitute the second equation into the first ([tex]x=-5[/tex]):
[tex]-5+2y=8,\\2y=13,\\y=\boxed{\frac{13}{2}}[/tex]
The second equation already denotes [tex]x=-5[/tex]. Therefore,
[tex]\boxed{x=-5,\\y=\frac{13}{2}}[/tex]
Answer:
x=-5
y=6.5
Step-by-step explanation:
if x=-5 then x+2y=8 could be rewriten as -5+2y=8 then you add 5 on both sides and you get 2y=13 then divide both sides by 2 and you get y=6.5

at positions A and B at the back of the stage. What angle of view between
the main characters does an actor at position C at center stage have? *
Answer:
The angle of view between the main characters is 80°.
Step-by-step explanation:
The angle of view of the actor C between actors A and B is the measure of the angle of the central arc between A and B. Hence, the angle of view between the main characters is 80°.

Write 1/3 x^2 - 4x + 17 in vertex form
Answer:
f(x)=−4(x+ 41 ) 2 − 4 11
Explanation:
The given function is
f(x) = - 4 {x}^{2} - 2x - 3f(x)=−4x 2 −2x−3
To write the function is vertex form, we need to complete the square.
We first factor -4 to get:
f(x) = - 4 ({x}^{2} + \frac{1}{2} x) - 3f(x−4(x2 + 21 x)−3
Add and subtract the square of half the coefficient of x.
f(x) = - 4( {x}^{2} + \frac{1}{2} x + \frac{1}{16} ) - \frac{1}{4} - 3f(x)=−4(x 2 + 21 x+ 16 1 )− 41 −3
We factor the perfect square trinomial and simplify to get:
f(x) = - 4( {x + \frac{1}{4} )}^{2} - \frac{11}{4}f(x)=−4(x+ 41 ) 2 − 4 11

Jodie ran at an average speed of 6 km/h for 10 minutes.
How far did she run in km?
Answer:
Distance cover by Jodie = 1 kilometer
Step-by-step explanation:
Given;
Speed of Jodie = 6 kilometer/ hour
Total time Jodie ran = 10 minutes
Find:
Distance cover by Jodie
Computation:
Total time Jodie ran = 10 minutes = 10 / 60 = 0.1667 hour
Distance = Speed x time
Distance cover by Jodie = Speed of Jodie x Total time Jodie ran
Distance cover by Jodie = 6 x 0.1667
Distance cover by Jodie = 1.002
Distance cover by Jodie = 1 kilometer

Cary sets up a checking account with an initial balance of $27,700, and the rent for her
apartment is deducted every month for a year. After a year the balance is $7900
(Assume no other transactions occur on the account)
Answer:
$1,650
Step-by-step explanation:
First, we need to find how much she paid the whole year. 27,700-x=7900. If we subtract 7900 from each side and add x to each side, we get 19,800=x. Therefore, she paid $19,800 in rent the whole year. Since there are 12 months in a year, and each month she paid the same, she paid $1,650 in rent each year, for 19800/12=1650

The LCM of three numbers is 360 and the GCD of the same numbers is 2.If one of the numbers is 40.Find the other 2 numbers
Answer
“The LCM of three numbers is 360“ The prime factors of 360 are 2³×3²×5¹. That means:
At least one of the numbers contains 2³ in its factorization list.
At least one of the numbers contains 3² in its factorization list.
At least one of the numbers contains 5 in its factorization list.
“One of the numbers is 40“ The factorization list of 40 is 2³×5, so 1) and 3) are satisfied.
“The GCD of the same numbers is 2“ This implies that all 3 numbers are even, and that at least one number only has one 2.
The candidates for the 2nd number, that has 3², are: 18, 12, 72 (3²×2³), 120, 180, or 360.
The candidates for the 3rd number depends on how many 2s the 2nd number has.
If more than one: 2, 6, 18, 10, 30, 90
If only 1, those plus 4, 8, 12, 36, 72, 20, 40, 120, 180, 360
find the eighth term of an arithmetic sequence if the first term is 5 and the common difference is 6
Answer:
47
Step-by-step explanation:
Formula for finding nth term of an arithemetic sequence is:

Solve the equation. 6g = 48 what does g equal?
Answer:
8
Step-by-step explanation:
First we need to figure out what g equals
Since 6 x 8 = 48 your answer would be 8
6 x 8 = 48
~ LadyBrain
The value of g that satisfies the equation is 8.
To solve the equation 6g = 48 and find the value of g, we can isolate the variable g by dividing both sides of the equation by 6:
6g / 6 = 48 / 6
This simplifies to:
g = 8
Therefore, g equals 8. By dividing both sides of the equation by 6, we find that when g is multiplied by 6, it results in 48. Hence, the value of g that satisfies the equation is 8.

Chris is playing a card game with his friends. The game uses only the four aces from a standard deck of cards. For each move, a player draws one card, replaces it, and then draws the second card.
Answer:
1/4
Step-by-step explanation:
Let's call the aces for hearts, diamonds, clubs, and spades. So, are red and [tex] c, s[/tex] is black.
Since the first card is replaced, the two picks are identical. This means that the sample space is given by all the possible couple
There are 16 such couples (we have four choices for the first card, and the same four choices for the second card). Now let's compute the odds in our favor to deduce the probability of winning:
If we want a player to draw two cards of the same color, the following couples are good:
so 8 possible couples over 16. This means that a player's probability of drawing two cards of the same color is 8/16 = 1/2.
Similarly, the probability of drawing a red ace first and then a black ace is represented by the following couples:
which are 4 over the same 16 as above, thus leading to a probability of 4/16 = 1/4.
