The formular which can be used to obtain the monthly charges as a function of the number of cheques written is 9.75 + 0.15x
Charges on account :
- Charge per check written = $0.15
- Monthly services charge = $9.75
The total amount charged monthly, F as a function of the number of cheques written, x can be expressed thus :
Monthly service charge + (charge per check × number of cheques written)
F(x) = 9.75 + 0.15x
Therefore, the charge function which can be used to calculate the total monthly charge on his account ls F(x) = 9.75 + 0.15x

Representing probability with area
When D= M-W =0, their heights are equal. When the man is taller, D is positive, and when the woman is taller, D is negative. Since we know the distribution of the difference D is normally distributed, the probability that the woman is taller than the man can be found by calculating the shaded area below D=0, in the corresponding normal distribution:
A standard normal curve is plotted on a horizontal axis representing D, that goes from negative 17 to 37. The mean, or mu sub D, = 10. The standard deviations, or sigma sub D = 9. The value 0 is marked. The area under the curve to the left of 0 is shaded, representing the probability that the woman is taller. The area to the right represents the probability that the man is taller.

Answer:
It should be 1/2 sorry if i"m wrong
Answer:
Step-by-step explanation:
45% = 45/100 = 0.45
- 0.45x = 18
- x = 18/0.45
- x = 40
100% is $40
Answer:
Work:
x^2 + 4x - 4 = 8
x^2 +4x -12 = 0
(x + 6) (x - 2) = 0
x = -6 and 2
