i think 55/14 if not srry
Step-by-step explanation:
<u>Answer</u>
c. 62/95
<u>Explanation</u>
Probability is the chance of an event happening.
Probability = (favorable outcome)/(total outcome)
P(girl) = 12/20 × 11/19
= (12×11)/(20×19)
= 132/380
= 33/95
P( not a girl) = 1 - 33/95
= 62/95
Can you format it properly it’s confusing to read in this for
I assume you want to find x^2+y^2 which is "x squared plus y squared"
x+y = 8
(x+y)^2 = 8^2 ... square both sides
x^2+2xy+y^2 = 64 ... use the FOIL rule
x^2+2(2)+y^2 = 64 ... replace xy with 2 (since xy = 2)
x^2+4+y^2 = 64
x^2+y^2+4 = 64
x^2+y^2+4-4 = 64-4 ... subtract 4 from both sides
x^2+y^2 = 60
Answer: 60
Devide the numerator by the denominator, and look for the repeating numbers
17 divided by 60 = 0.283333333 = repeating
25 divided by 60 = 0.4166666667 = terminating at the 7
31 divided by 44 = 0.7045454545= repeating i think? sorry i cant remember if double numbers repeating like this is the same
54 divided by 72= 0.75 = terminating
