The table represents an exponential function.

Mathematics
1 answer:
Harlamova29_29 [7]3 years ago
5 0

Answer (B) 2/3

Explanation: the multiplicative rate is the ratio of the values y(k)/y(k+1) (with k being the index).  This ratio must be the same for the function to be exponential. We can take y(2)/y(1) = 4/6 = 2/3.

We can use 2/3 to verify the remaining entries:

x=3: 4*2/3 = 8/3 = y(3)

x=4: (8/3)*(2/3)=16/9=y(3)

40. In a statistics class of 30 students, there were 13 men and 17 women. Two of the men and three of the women received an A in
Harrizon [31]

Answer:

a) 56.67% probability that the student is a woman

b) 16.67% probability that the student received an A

c) 63.33% probability that the student is a woman or received an A.

d) 83.33% probability that the student did not receive an A.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have that:

30 students

13 men

17 women

2 men that got an A and 11 men that did not get an A.

3 women that got an A and 14 women that did not get an A.

a. Find the probability that the student is a woman.

30 students, of which 17 are women.

P = \frac{17}{30} = 0.5667

56.67% probability that the student is a woman

b. Find the probability that the student received an A.

30 students, of which 5 received an A

P = \frac{5}{30} = 0.1667

16.67% probability that the student received an A

c. Find the probability that the student is a woman or received an A.

30 students, of which 17 are women and 2 are men who received an A. So

P = \frac{19}{30} = 0.6333

63.33% probability that the student is a woman or received an A.

d. Find the probability that the student did not receive an A.

30 students, of which 25 did not receive an A.

P = \frac{25}{30} = 0.8333

83.33% probability that the student did not receive an A.

How many different books did the children read
Alex777 [14]

Answer:

16 books

Step-by-step explanation:

if Sandra read 5 books and Deacon read 6 and Breanna read 7 and they all one same book, then that means sandra read 4 different books then Deacon and Breanna. Deacon read 5 different books then Sandra and Breanna. Breanna read 6 different books then Deacon and Sandra.

So Sandras 4 books plus Deacons 5 books plus Breannas 6 books equals up to 15 but, now you need to add the one book they all read which makes the answer 16.


(Hopes this helps)

Joshua spends 25 minutes of each day reading.Let d be the number of days that he reads and let m represent the total minutes of
snow_tiger [21]
The independent variable is the days he spends reading because nothing we have can determine that. However the dependent variable is the total minutes of reading because it relies on the independent variable to figure out. You can't find the total minutes without knowing the days he spends. The equation sould be d times the amount he reads per day =m
