You can set up a simple algebraic equivalent to find a number equivalent to 200 after being multiplied by 3 and added 11 to.
3x+11=200
3x=189
x=63
Had to edit! Realized what I had done wrong
We are given dimension of billboard as 30 feet by 18ft.
since billboard is a rectangle so Area =l *b
Area of billboard = 30*18=540 feet square
1 gallon of paint covers 250 square feet
so for 540 square feet paint needed = 540/250 = 2.16 gallons
Answer: 2.16 gallons should be purchased to cover the entire billboard
Answer:
1) The probability that the second apple is red is 0.7143 (71.43%).
2) The probability that at least one red apple is picked 0.9341 (93.41%).
Step-by-step explanation:
We can make a probability tree as the attached picture.
1) There are 2 ways in the probability tree when the second apple is red:
Both apples are red:
P(R∩R)==0.4945
Only the second apple is red:
P(Y∩R)==0.2198
The probability that the second apple is red is the sum of the previous probabilities.
P(2nd R)=P(R∩R)+P(Y∩R)=0.4945+0.2198=0.7143
2) To find the probability that at least one apple is red, we can get the probability of none of the apples is red and then it will be subtracted from 1.
The way in the probability tree is Y∩Y:
P(Y∩Y)==0.0659
P(at least 1 R)= 1-P(Y∩Y)=1-0.0659=0.9341
Answer:

Answer:
True
Step-by-step explanation:
e^{i\pi} + 1 = 0
Simplifying and therefore meaning that the answer is true.
But in all seriousness 6*3 = 18
6*4a = 24a
So yes it is true :)
