Big fat guess</em></u></h2>
You have to use the Pythagoreas theorem where you do 3 squared + 4 squared=25
Then you square root 25 which is 5 so
c is 5
<h3>
Answer: 4/9</h3>
========================================================
Explanation:
The outcomes of the die are {1,2,3,4,5,6} which is the sample space.
The values less than 5 are {1,2,3,4}
There are 4 values we want out of 6 total, so 4/6 = 2/3 is the probability of rolling something less than 5 on a single die.
The probability of getting two such values in a row is (2/3)*(2/3) = 4/9
Each die roll is independent of any other.
Answer:
a)78
b)82.95
Step-by-step explanation:
To get the amount something is marked up you just need to multiply it by
1+0.(the%)
so in this case you multiply 60 by 1.30 to get 78
To get a discount you just have to do the same but without the +1
so 88*0.15
should get you the discount amount (13.2)
which you subtract from the original number (88-13.2 = 74.8)
now to get sales tax you would multiply the 79 by 0.05 which is 3.95
and add that to the total of 78.75 since sales tax applies AFTER coupons
