Draw a triangle in the graph and use the Pythagorean theorem.
P(A|B) = P(A)*P(B) - P(A∩B)
Here, we have:
P(a 6 is chosen, given that a diamond was already chosen) = (1/4)(1/4)-(1/52) = 0.043
Answer:
The distance between Amanda and the helicopter be x

Answer:
He saved $25.
Step-by-step explanation:
- If Rob saves $5 for every $16 he earns, he is saving the folowing franction of his income: .
- Then if his income equals $16, he will save .
- If his income is $80, he will save
- Another way to understand this problem would be to think that . Then, receiving $80 is the same as receiving 5 times $16. If he saves $5 for every $16 he receives, he would save 5 times $5 = $25.
X/3 -10=6
Add 10 to both sides
x/3= 16
Multiply both sides by 3
x=48
Final answer: x=48
