Answer:
25%
Step-by-step explanation:
when we count, we know that there are 8 possible outcomes as to where the spinner will land.
<em>{the following will be assuming each section has an equal chance of being landed on; that the spinner is not weighted}</em>
<em />
We know that two of these 8 possibilities are "A"
This means that A has a 2/8 chance of being landed on
we can simplify 2/8 to 1/4; because they are equivalent ratios/fractions
to calculate percentage, we can follow through with our equation of 1/4
[divide 1 by 4]
1 / 4 = 0.25
We multiply this number by 100 to find percentage,
0.25 × 100 = 25
meaning that A has a 25% chance of being spun
hope this helps!! have a lovely day :)
Answer:
-5 ÷ 4 = -1.25 or 1 
The answer is -1.25
I hope that this helps you! ^‿^
Answer:
Perpendicular ⇒
m = -1/-4 = 1/4
g(x) = (1/4)x + b
3/4 = (1/4)(5) + b
b = -1/2
g(x) = (1/4)x - 1/2
Step-by-step explanation:
First off, we'll convert the mixed fractions to "improper",
we know that
The probability that "at least one" is the probability of exactly one, exactly 2, exactly 3, 4 and 5 contain salmonella.
The easiest way to solve this is to recognise that "at least one" is ALL 100% of the possibilities EXCEPT that none have salmonella.
If the probability that any one egg has 1/6 chance of salmonella
then
the probability that any one egg will not have salmonella = 5/6.
Therefore
for all 5 to not have salmonella
= (5/6)^5 = 3125 / 7776
= 0.401877 = 0.40 to 2 decimal places
REMEMBER this is the probability that NONE have salmonella
Therefore
the probability that at least one does = 1 - 0.40
= 0.60
the answer is
0.60 or 60%
