John works a fortnightly wage of $750.00. If his basic week is 40 hours. what is his: Weekly wage basic rate and basic fortnight

Vladimir [108]

Answer:

Basic wage rate = $9.375 per hour

Step-by-step explanation:

Given :

Fortnight wage = $750

Basic week, hours worked per week = 40 hours

Weekly basic wage rate :

Fortnight = 2 weeks

Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375

Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour

Fraz is running a science fair experiment where mice run through a maze with 4 turns. At each turn, the mouse can take a right o

kherson [118]

Answer:

the probability is 0.125

Step-by-step explanation:

The number of ways in which the mouse can move in the 4 turns is calculated using the rule of multiplication as:

2 * 2 * 2 * 2 = 16

1st turn 2nd turn 3rd turn 4th turn

Because the mouse can take two options at every turn, right or left.

Now, from the 16 possibilities of movements, a mouse will find an exit in just two options:

1. right-right-left-left

2. left-right-right-left

So, the probability that a mouse will find an exit is:

$P=\frac{2}{16}=0.125$

Because, there are 16 possibilities and a mouse will find an exit using 2 of them.
