Cathy is paid at a rate of K7.20 per hour for a basic hour-week of 70 hours. She is paid time-and-a-half for over-time during th
Levart [38]

Answer:

K1310.4

Step-by-step explanation:

Basic pay per hour = K7.20

Overtime pay during the week per hour = 1 1/2 * K7. 20 = K10.8

Weekends = 2 * K7.20 = K14.4

Basic hours per week = 70 hours

In a fortnight :

Basic hours = 70 * 2 = 140 hours :

Hence, Overtime during the week = (160 - 140) = 20 hours

Weekend hours = (4 +2) = 6 hours

Total earning :

(140 * 7.20) + (20 * 10.8) + (6 * 14.4)

1008 + 216 + 86.4

= K1310.4

Given two dice, what is the probability of rolling a four on the second die, given that you already rolled a four on the first d
Sholpan [36]

Answer:   1/6

Reason:

There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.

The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.
