Basically you multiply the probabilities
So 92/100 * 92/100 = 0.8464 so around 84-85%
$513 (amount earned) / 54 (amount of hours) = $9.50 (hourly rate)
to check:
$9.50 (hourly rate) x 54 (amount of hours)
= 513 (amount earned)
hope this helps :)
Answer:
The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
We can substitute a definition of one of the variables by rearranging the first equation.
We set the first equation equal to one of our two variables.
Now we substitute this equality into our second equation
Ok, let's simplify the left side first by adding the x's together
We get:
12x+5=12x+y
So if we subtract 12x from each side, it cancels it out on both sides, leaving us with 5=y or y=5
If we plug that back into the original we simplified of 12x+5=12x+y, we would have: 12x+5=12x+5, which is true. :D
Well
<span>
4 x 5 = 20
and
5 x 5 = 25
I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:
6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )
So
6 x 7 = 42
There are faster methods but this is probably the best way to start out.
