In a box of 15 tablets, 4 of the tablets are defective. three tablets are selected at random. what is the probability that a store buys three tablets and receives: a) no defective tablets, b) one defective tablet, and c) at least one non-defective tablet.
total measurement of any triangle is 180 degrees.
area of a triangle = 1/2 * base * height
= 1/2 * 4 * 9
= 1/2 * 36
= 18 in^2.
a linear graph is one with a line that has the same slope all the way through. in this case, you can tell the line doesn't have the same slope the whole way through because at one part it flattens and also decreases.
increasing would mean the slope of the line is positive, or it appears to be going upwards. constant would be the slope is 0, and it's just a horizontal line. decreasing would be the slope of the line is negative, and it appears to be going downwards. in this case, this would mean that the segment k is increasing, because it appears to be going upwards, l would be constant, because it is a horizontal line, and m would be decreasing, because it's going downwards.
i would say the ant started moving away from the hole for 2 seconds, and then stopped for 3 seconds, and then started moving again back to the hole for another 3 seconds.
so first you have the parralelogram right then you put the triangle on the other side to make it a rectangle. then you multiply 4 times 10 is your answer so b
