Answer:
B
Step-by-step explanation:
Let's plot these points (see diagram).
The base is the horizontal length of the parallelogram, while the height is the the perpendicular distance from the top base to the bottom base.
We can see from the graph that the base is 8 units and the height is 3 units. The area of a parallelogram is A = bh, where b is the base and h is the height. Here, the base is 8 and the height is 3, so the area is A = 8 * 3 = 24 square units.
The answer is B.
Answer:
(4x+3)^2 = 18
16x+9=18
16x=9
<u>x=9/16</u>
Step-by-step explanation:
5 numbers chosen from 25 can be done in 25C5 = 25!/(5!*20!) = 53,130 ways. The probability of choosing the correct set of 5 numbers is
1/53,130
#3. the probability of spinning "rock" is 25% or 1/4 so we can use this probability to predict the number of times we would expect to get "rock" in 80 spins as follows:
25% of 80 = .25(80) = 20 So how likely is it we spin 20 'rock' out of 80 spins? At 25%, not very likely..
#4.
A. True
B. True
C. False, the theoretical probability of make make using the spinner is

or about 56%
