Answer:
B
Step-by-step explanation:
20*3=60
20*7=140
20*11=220
It can't, in triangle sum of 2 sides have to be more than 3rd side, and we know that

isn't more than

I also add picture to make it more clear, circles represents range of each side
Answer:
The relation is a linear function with the equation: y = -6/5x + 3/5
Step-by-step explanation:
Question 5)
The given graph is a straight line.
We know that the graph of a linear function is a straight line that can be written in the form

where m is the slope and b is the y-intercept
The slope of the line can be determined by taking two points
(3, -3)
(-2, 3)
Finding the slope




From the graph, the y-intercept can be obtained by setting x=0 and check the corresponding y-value of y.
or substituting m = -6/5 and (3, -3) in the slope-intercept form to determine y-intercept 'b'.




now substituting m = -6/5 and b = 3/5 in the slope-intercept form to determine the equation of the linear function
y=mx+b
y = -6/5x + 3/5
Therefore, the relation is a linear function with the equation: y = -6/5x + 3/5
Answer:
\frac{17}{24}
Step-by-step explanation:
Given that Box 1 contains 2 red balls and 1 blue ball. Box 2 contains 3 blue balls and 1 red ball. A coin is tossed. If it falls heads up, box 1 is selected and a ball is drawn. If it falls tails up, box 2 is selected and a ball is drawn.
P(selecting Box 1) = 0.5 = P(selecting II box) (assuming a fair coin is tossed)
P(Red/Box I ) = 
P(Red/Box II) = 
Box 1 and Box 2 are mutually exclusive and exhaustive events.
So probability of selecting a red ball.
= probability of selecting a red ball from box 1 + probability of selecting a red ball frm box 2
