Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
From the given pi chart,
Total outcome = 360degrees (since the total angle in a circle is 360 degrees)
Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;
Expected outcome = 40degrees
Pr(scoring a 5) = 40/360
Pr(scoring a 5) = 1/9
Hence the probability of scoring a 5 is 1/9
Answer:
Two j plus three plus j multiplied by 6.
Step-by-step explanation:
First we say what is in the parenthesis, that would be (2j + 3 + j) So, two j plus 3 plus j.
Then you add the "multiplied by six"
****My answer is incorrect, please refer to the conversation for answer.
To find out, we solve the system of equations.
n + q = 52
n = -q + 52
Plug in -q + 52 for 'n' in the 2nd equation:
0.05(-q + 52) + 0.25q = 8
Distribute 0.05:
-0.05q + 2.6 + 0.25q = 8
Combine like terms:
0.2q + 2.6 = 8
Subtract 2.6 to both sides:
0.2q = 5.4
Divide 0.2 to both sides:
q = 27
Now plug this into any of the two equations to find 'n':
n + q = 52
n + 27 = 52
Subtract 27 to both sides:
n = 25
So Alexis had 27 quarters and 25 nickels.
