Started with: $60
left with: $10
items bought: 20
60 - 10 = 50 < amount spent
50/20 = amount spent/items bought
= $ 2.50 < each chocolate
you can check this by multiplying the items bought and the amount each item cost to get how much you spent
20 × 2.5 = 50
Stephanie started off with 60 dollars and ended with 10 dollars
60 - 50 = 10
hope this helps :)
Answer:
about $1.34
Step-by-step explanation:
Answer:
P(A|B) = 8/12 = 66.67%
Step-by-step explanation:
From 1 to 24, the number of odd numbers is 12, so event B has 12 possible values.
Among these 12 odd numbers in B, the ones that are prime are:
3, 5, 7, 11, 13, 17, 19, 23 (total of 8 numbers)
so given event B, the event A has 8 possible values inside the sample space of B.
So the probability of A given B, that is, P(A|B), is:
P(A|B) = 8/12 = 66.67%
Per 100 as in that many out of 100.
The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
<h3>What is wavelength?</h3>
The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.
We have two notes
Number of cycle for blue = 8
Number of cycle for red = 4
Ratio = 8:4 = 2:1
Or
2 to 1
Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
