Answer:
B. 35%
Step-by-step explanation:
P(winning $1.00)=40%
P(winning $5.00)=20%
P(winning $10.00)=5%
In a probability distribution, the sum of the probability must always be equal to 1.
Therefore:
P(winning $0.00)=1-(40%+20%+5%)
=1-(0.4+0.2+0.05)
=1-0.65
=0.35
The probability of winning nothing at all is 35%.
5x + 4 + 2x + 5
First add the like terms.
You will get this: 7x + 9
And these can't be simplified anymore because they do not both go into the same multiple.
So your answer will be:
7x + 9
Mathematics is not discovered, it is invented
Answer:
9 cm
Step-by-step explanation:
Side lengths of similar triangles are proportional. BC is 1.5 times the length of AC, so EF will be 1.5 times the length of DF:
1.5·6 cm = 9 cm
