do both the numerator and denominater
The ratio 9:7 gives you following statement:
- Carl will win in 9 cases from 9+7=16;
- Carl will lose in 7 cases from 16.
Then the probability that Carl will lose is
Answer:
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
(√7 + √3)^2
(√7)^2 + (√3)^2
7 + 3

Answer:
7 cm
Step-by-step explanation:
base area = (base length x base height)/2 = (2x6)/2 = 6 cm^2
height = V / base area = 42 / 6 = 7 cm
