Answer: 19/25.
Step-by-step explanation:
Given data:
Large marbles = 14
Small marbles = 11.
8 large marbles = green.
5 of small marbles = white.
Solution:
If 8 of large marbles are green, therefore the remaining 6 are white.
Likewise for the small marbles the remaining 6 are green marbles.
Total number of marbles = 14 + 11
= 25.
P(small or green) = P(small) + P (green) – P (Both)
= 11/25 + 14/25 – 6/11
= 19/25
Answer:
Answer is 0.7536
Step-by-step explanation:
Large Marbles = 14 Small Marbles = 11
Green LM = 8 Green SM = 6
White LM = 6 White SM = 5
QUESTION:
If a marble is randomly selected from the box, what is the probability that it is small or it is green?
Note the use of "or" and not "and".
SOLUTION:
In this case, the two events - small marble & green marble - are NOT mutually exclusive. This means that sometimes they occur together. We can have a marble that is both small and green!
The formula for this probability is hence
P(A or B) = P(A) + P(B) - P(A and B)
Let A = The event that the selected marble is small
B = The event that the selected marble is green
Total number of marbles = 14 + 11 = 25
P(A or B) = 11/25 + (8+6)/25 - [P(A) × P(B)]
P(A or B) = 11/25 + 14/25 - [11/25 × 14/25]
= 0.44 + 0.56 - 0.2464 = 1 - 0.2464 = 0.7536

Answer:
78/16=
39/8=
19.5/4= 4.80805
16 is 20.51% of the number 78.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let x percent of 78 is 16.
So, x% of 78 = 16
x/100 (78)= 16
78x = 1600
x= 1600/78
x = 20.51%
Hence, 20.51 percent of 78 is 16.

Bryce had a $25 gift card to use on songs and games at an online media store. Songs cost $2 each and games cost $5 each. Bryce spent all the money on the gift card to download 8 items. Solve the system to determine how many games he purchased. Let s represent the number of songs and g represent the number of games. s + g = 8 2s + 5g = 25 Bryce purchased games.
Answer:
Bryce purchased 3 games.
Step-by-step explanation:
To find the number of songs and games that Bryce downloaded, we need to solve the following system of equations:
s + g = 8
2s + 5g = 25
We know that:
s + g = 8 → 2s + 2g = 16 → 2s = 16 -2g
2s + 5g = 25 → 16 - 2g + 5g = 25
→3g = 25 - 16
→3g = 9
→ g = 3
Therefore, bryce downloaded 3 games and 5 songs!

Which must be larger log 15 Or In 15? And why
Answer:
ln 15 must be greater (larger than) if log 15 is common.
Step-by-step explanation:
log 15 [assumed to be a common logarithm]
‹–› 15 = 10 ^ log(15)
ln 15 [natural log which has a base of e] ‹–› 15 = e ^ ln(15).
10 > e
e ≈ 2.7218.
e is approximately 3 rounded to the nearest whole number.
Logically you would need to raise 3 to a greater power for 3ⁿ = 15. Than 10ⁿ = 15.
For example 3² < 10² → 3³ < 10³ → 3⁴ < 10⁴ → ... Thus 3ⁿ < 10ⁿ for n > 0.

Explain how solving -7y > 161 is different from solving 7y > -161.
To solve -7y > 161, we divide both sides by -7 and we get y < -23. The inequality sign flipped because we divided both sides by a negative number.
To solve 7y > -161, we divide both sides by 7 and it leads to y > -23. The inequality sign does not flip in this case, because we are not dividing both sides by a negative number.
The similarities is that we end up with -23 on the right side, but the inequality signs are different.

1. In a supermarket, each orange costs $3, and each apple costs $2. If you want to spend
exactly $45, write an equation in standard form modeling this situation. Let o represent
the number of oranges you buy, and a represent the number of apples you buy.
Answer:
3o + 2a = $45 ( you can buy 9 oranges and 9 apples)
Step-by-step explanation:
First I divided 45 by 3 and I got 15 so now I know that 15 is the highest amount of oranges I can buy without going over $45. I also know that 15 cannot be an answer because I also have to buy apples.
Then I divided 45 by 2 and 22 was the highest whole number.
Now I would play trial and error BUT i know that the number for oranges have to be less that 15 and the number for apples has to be less than 22.
3 times 9 equals 27 (oranges)
45 - 27 = 18
2 times 9 equals 18 (apples)
3o+2a =$45 is the equation in standard form modeling this situation.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that in a supermarket, each orange costs $3, and each apple costs $2.
Let o represents the number of oranges you buy
and a represent the number of apples you buy.
If you want to spend exactly $45
We have to find the equation to model this situation
3o+2a =$45
Hence, 3o+2a =$45 is the equation in standard form modeling this situation.

one school purchased 18 gallons of blue paint to decorate several of its classrooms. if each classroom needs 1 4/5 gallons of paint, then how many classrooms will get painted.
Answer:
18 gallons of paint could paint 10 classrooms.
Step-by-step explanation:
Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:
4/5 = 0.8
1 + 0.8 = 1.8
18 / 1.8 = 10
Therefore, 18 gallons of paint could paint 10 classrooms.
