Answer:
28 pieces
Step-by-step explanation:
14.9 ÷ 0.52 = 28.653
Answer:
You stopped at 2y-4=12
If we add same number to both sides the equation will remain true. For example if we have 5=5, and we add 7 to both sides, we get 12=12 which is also true. Now let's do this with our equation. Add 4 to both sides(to have only y on the left side). We get 2y=16, hence y=8.
Answer. 2y=16
Answer:
The ratio between two values A and B is just the quotient between these two values:
ratio = A/B
a) $280 in 7m
Here the ratio is:
$280/7m = $40/m
This also can be read as:
$40 per meter.
b) 105 miles in 2 hours
Here the ratio is:
105mi/2h = 52.5 mi/h
This also can be read as:
52.5 miles per hour
c) $33 for 5lb
The ratio is:
$33/5lb = $6.6/lb
This can be read as:
$6.6 per pound.
d) 50 pages in 2 hours
the ratio is:
(50 pages)/2h = 25 pages/h
this can be read as:
25 pages per hour.
Answer: Probability that a student chosen at random likes science given that he or she likes art is 58%
Step-by-step explanation:
Since we have given that
Probability that a student who likes art and science = 21%
Probability that a student who likes art = 36%
According to question,
we need to find the probability that a student chosen at random likes science given that he or she likes art.
So, we will use "Conditional Probability":
P(A) = 0.36
P(S ∩ A) = 0.21
![P(S\mid A)=\frac{P(S\cap A)}{P(A)}\\\\P(S\mid A)=\frac{0.21}{0.36}\\\\P(S\mid A)=0.58\\\\P(S\mid A)=58\%](https://tex.z-dn.net/?f=P%28S%5Cmid%20A%29%3D%5Cfrac%7BP%28S%5Ccap%20A%29%7D%7BP%28A%29%7D%5C%5C%5C%5CP%28S%5Cmid%20A%29%3D%5Cfrac%7B0.21%7D%7B0.36%7D%5C%5C%5C%5CP%28S%5Cmid%20A%29%3D0.58%5C%5C%5C%5CP%28S%5Cmid%20A%29%3D58%5C%25)
Hence, Probability that a student chosen at random likes science given that he or she likes art is 58%.
