Answer:

1. false

2. 17 times

Step-by-step explanation:

The sum of all the probabilities of outcomes of an event is equal to 1

2. A die has 1,2,3,4,5,6

P(4) = number of 4's/ total numbers

= 1/6

Multiply the number of roll's by the probability of getting a 4

100 *1/6 = 50/3 = 16 2/3

This is approximately 17

Column A

Viefleur [7K]

The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:

$m= \frac{b-d}{a-c}$ .

Thus, the slope in A is $m= \frac{12-2}{-4-(-10)}=\frac{10}{6}=\frac{5}{3}$ .

The slope in B is $m= \frac{-4-10}{6-18}=\frac{-14}{-12}=\frac{7}{6}$ .

Now, to compare 7/6 to 5/3, we can write the second fraction as 10/6.

So, the slope in A is larger than the slope in B.
