, making sure it equals 3.
Answer:
4m X 6m
Step-by-step explanation:
This is because if there is a 2m square in the middle, there is 8 m of usable space left along both sides of the garden.
Because the 2m square was in the middle, there is 8/2 = 4m along each width of the 4 small rectangles.
Becuase 4m is the width, there is 10 - 4 = 6m along each rectangle's length.
Answer:
B. No, because the trials of the experiment are not independent and the probability of success differs from trial to trial.
Step-by-step explanation:
The first criterion of a binomial distribution is a fixed number of trials. Selecting 5 senators means the number of trials is 5, which is a fixed number.
The next criterion is that the trials must be independent. Selecting the senators without replacement means the trials are dependent, not independent; this means that this is not a binomial distribution.
Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here { a, b ] = [ - 1, 2 ], thus
f(b) = 4 ← from (2, 4 )
f(a) = 
← from (- 1, ) , thus
average rate of change = 
= 
= 
→ D
Answer: -1 1/2 to -1: -1 1/3 and -5/4
-1 to -1/2: -2/3, -3/4, -6/7, -5/6
-1/2 to 0: -1/3 and -3/8
0 to 1/2: 1/5, 1/10, 3/12, 3/8, 3/7, 1/3
1/2 to 1: 4/5, 6/10, 7/8, 7/9, 3/4, 8/10
1 to 1 1/2: 1 5/12, 9/8
