The probability that the number of spoiled eggs among the 3 selected is 2 will be 0.57.
<h3>What is probability?</h3>
The probability of favorable events to the total number of occurrences.
A really bad carton of 7 eggs contains 5 spoiled eggs. An unsuspecting chef picks 3 eggs at random for his "Mega-Omelet Surprise".
Then the probability that the number of spoiled eggs among the 3 selected is 2 will be
The total number of the event will be
Total = ⁷C₃
Total = 35
Then the probability will be
P = (⁵C₂ x ²C₁) / 35
P = 10 x 2 / 35
P = 20 / 35
P = 0.57

Answer:
The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship ⇒ last answer
Step-by-step explanation:
* Lets explain how to sole the problem
- Proportional relationship describes a simple relation between
two variables
- In direct proportion if one variable increases, then the other variable
increases and if one variable decreases, then the other variable
decreases
- In inverse proportion if one variable increases, then the other variable
decreases and if one variable decreases, then the other variable
increases
- The ratio between the two variables is always constant
- Ex: If x and y are in direct proportion, then x = ky, where k
is constant
If x and y in inverse proportion, then x = k/y, where k is constant
* Lets solve the problem
# Last table
∵ x = 3 and y = 6
∴ x/y = 3/6 = 1/2
∵ x = 5 and y = 10
∴ x/y = 5/10 = 1/2
∵ 1/2 is constant
∵ x/y = constant
∴ x and y are proportion
* The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship
Answer:1000cm
Step-by-step explanation:
Volume=length ×width×height
Each side is 10
10×10×10=1000
Answer:
20t
Step-by-step explanation:
15 is where the boat started so 20t is how much the boat traveled from the origional position of 15
Answer:
f'(x)=-(x+42)/5
Step-by-step explanation:
Rewrite f(x) as y:
y=-5x-42
Flip x and y and solve for y:
x=-5y-42
x+42=-5y
(x+42)/-5=y
So the inverse function is f'(x)=-(x+42)/5 (note that f' means inverse)
