The first thing we must do for this case is find the number of total guitarists.
We have then:

We now look for the relationship between the number of guitarists playing jazz alone to the total number of guitarists.
We have then:

Where,
x: number of guitarists playing jazz alone
From here, we clear the value of x.

Then, the number of guitarists who play classical solo is:

Answer:
30 guitarists play classical solos in the contest
Probability that the student got a 'C' GIVEN they are female = number of females that got a C in the test/number of females
From the information given,
number of females that got a C in the test = 12
number of females = 30
Thus,
Probability that the student got a 'C' GIVEN they are female = 12/30
We would simplify the fraction by dividing the numerator and denominator by 6. Thus,
Probability that the student got a 'C' GIVEN they are female = 2/5
Answer:
25%
Step-by-step explanation:
difference between 8 and 10 is 2, so 8 would need to increase by 2 to get to 10.
2 is 1/4 of 8, and 1/4 is 25%
answer is 25%
Answer:
p = 4
Step-by-step explanation:
Given equation:

<u>Standard equation of a circle:</u>

(where
is the centre of the circle, and
is the radius)
If you expand this equation, you will see that the coefficient of
is always one.
Therefore, 

<u>Additional information</u>
To rewrite the given equation in the standard form:





So this is a circle with centre (2, -3) and radius √29
