3,500 kilometers in one day
Answer:
<h3>1/4</h3>
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
Answer:
The frame will be 4 inches in width
Step-by-step explanation:
The length of the outside is 24+2x
The width of the outside is 20+2x
(24+2x)(20+2x) - 20(24) = 416
480 + 40x + 48x + 4x2 - 480 = 416
4x2 + 88x - 416 = 0
x2 + 22x - 104 = 0
(x+26)(x-4) = 0
x = -26 or x=4
The frame will be 4 inches in width
