Answer:
Hence the probability that she paid cash is 0.105
Step-by-step explanation:
P(cash) = 0.3
P(credit card ) = 0.3
P(debit card ) = 0.4
P ( more than $50 | cash ) = 0.2
P (more than $50 | credit card ) =0.9
P (more than $ 50 |debit card ) = 0.6
P ( more than $50) = P ( more than $50 | cash )* P (cash) + P (more than $50 credit card ) * P(credit card ) + P (more than $ 50 |debit card )* P(debit card )
= 0.2 * 0.3 + 0.9 * 0.3 + 0.6* 0.4
= 0.57
P ( more than $50) = P ( more than $50 | cash )* P (cash) / P ( more than $50)
= 0.2* 0.3 / 0.57
= 0.105
Answer:
1080
Step-by-step explanation:
just multiply all the numbers to get the area of the whole shape.
In math, a factor is a number being multiplied; for instance, if 7x5=35, 7 and 5 are both factors.
I think it is 150 but i am not that suere.
Answer:
Step-by-step explanation:
Let numbers be x and y
<u>Then we have equations:</u>
<u>Comparing</u>
- 4y = y + 87
- 4y - y = 87
- 3y = 87
- y = 87/3
- y = 29
<u>Then, the larger number is</u>
