Answer:
P(F) = 143/280
Step-by-step explanation:
The total number of female students is 109+34 = 143.
The total number of non-female students is 38+99 = 137.
Then the total number of students is 143+137 = 280.
If a student is picked at random, the probability they are female is ...
P(F) = 143/280
Step-by-step explanation:
f(x) = 4x - 1
g(x) = 3x - 2
1) f(x) + g(x) = (4x - 1) + (3x - 2)
= 4x - 1 + 3x - 2
= 4x + 3x -1 - 2 = 7x - 3
2) f(x) * g(x) = (4x - 1) * (3x - 2)
= 12x^2 - 8x - 3x + 2
= 12x^2 -11x + 2
3) f(g(x)) = 4(3x - 2) - 1
= 12x - 8 - 1
= 12x - 9
4) f(x) - g(x) = (4x - 1) - (3x - 2)
= 4x - 1 - 3x + 2
= 4x - 3x - 1 +2
= x + 1
Answer:
1.2 is the decimal, 1 1/5 will be the fraction.
Step-by-step explanation:
Convert the percentage to a fraction by dividing by 100 which leaves us with 1.2
We split the value into two parts, 1 and 0.2
1 is just 1 as a fraction
0.2 is equivalent to 1/5
Together it is 1 1/5
