Answer: 16,384
Step-by-step explanation:
The seven marbles have different colours, so we can differentiate them.
Now, suppose that for each marble we have a selection, where the selection is in which jar we put it.
For the first marble, we have 4 options ( we have 4 jars)
For the second marble, we have 4 options.
Same for the third, for the fourth, etc.
Now, the total number of combinations is equal to the product of the number of options for each selection.
We have 7 selections and 4 options for each selection, then the total number of combinations is:
C = 4^7 = 16,384
Answer:
We choose B. (1, 10)
Step-by-step explanation:
Given the exponential model in the form y = a
- passes through the points (2, 50)
<=> 50 = a
<=> a = (1)
- passes through the points (3, 250)
<=> 250 = a (2)
Substitute (1) into (2) we have:
250 =
<=> 50b = 250
<=> b = 5
=> a = = 2
Hence, our exponential model is: y =2*
Let analyse all possible answer:
A. (0, 5) we have: y =2* ≠ 5 so it is wrong
B. (1, 10) we have: y = 2* so it is true
C. (4, 450) we have: y = 2* ≠ 450 so it is wrong
D. (5, 650) we have: y = 2* ≠ 650 so it is wrong
Hence we choose B. (1, 10)
Answer:
S(B(r))
Step-by-step explanation:
B = sleep hour
S = practice hour
S(B(r))
(0,0), (1,1)
Basically, any point that is shaded.
