I guess you mean 5m and 14m are the lengths of 2 sides of the triangle.
If the length of any side is equal or greater than the sum of the other 2 sides then you can;t make a triangle.
So for example 19 cannot the answer because 19 = 5 + 14 . No triangle can be formed with sides that measure.
and 38 is greater than 14 + 5 so its cant be C.
The answer is A
$4.25 + $1.50 = $5.75= 2 miles
10 x $1.50 = $15.00=10 miles
10 + 2 = 12 miles
$5.75 + $15.00 = $20.75
3/6 is the answer
3/6is 0.50 and 2/5 is 0.40
Just divide them
Answer:
area is 9cm2 perimeter 20 cm
Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
