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
Answer:
Equation of the line:
.
Step-by-step explanation:
Let
and
denote the coordinates of these two points, respectively.
Calculate the slope
of this line:
.
Notice that the slope is zero because the two points have the same
-coordinates (
) even though their
-coordinates are distinct (
.)
Equation for this line in point-slope form:
.
.
Rewrite and simplify to obtain the equation of this line in slope-intercept form:
.
The
-term was eliminated because the slope was zero.
Try writing and solving an equation of proportions:
4 5
---- = ----
6 x
Then 4x = 30, and x = 7.5 (answer)
2 1/4 x 24 x 8
9/4 x 24= 54
54 x 8 = <u>432 crayons</u>
