The expected value of the inseam length of the jeans is found as
30% of 30+ 25% of 32+ 10% of 34+ 10% of 36 + 10% of 38 + 15% of 40
= 
= 
Hence, the third option 33.8 is the correct expected value.
A because the feed sets discounts rate and primes
Answer:
Step-by-step explanation:
Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x
-12x+12x+72=-24
The xs cancel, which leaves you with 72=-24
Since 72 cannot equal -24 there is no answer to this system of equations
Answer:
83% remains in the box
Step-by-step explanation:
Here, we are interested in calculating the percentage of donuts remaining in the box.
From the question, we are told that 2 was eaten, the number of donuts left = 12-2 = 10 donuts
The percentage of donuts left would be;
Number of donuts left/Total no of donuts * 100%
= 10/12 * 100 = 83.33
Which is 83% to the nearest whole number percentage
