The graph shows the exponential regression model for data representing a rabbit population after x years. Which is true of the r

tamaranim1 [39]

Answer: The graph of the regression model can be used to predict the population size for any number of years in the future.

Step-by-step explanation:

Since with help of the given graph, we can say that

The graph of the regression model is applied for the every real value of x.

Thus the statement The graph of the regression model is limited to whole-number values for x is false.

Also, the range of an exponential function is always a set of real number.

Therefore, The graph of the regression model is limited to whole-number values for y is false.

Since, for 1 year, the approximate population is given,

Therefore, The graph of the regression model cannot be used to approximate the population size for year 1 is false.

Again according to the given graph we can say that we can get the population for any number of year.

Thus, The graph of the regression model can be used to predict the population size for any number of years in the future is true.

Two numbers have a difference of 12. The smaller of the two numbers is 3 less than double the other. What are the two numbers?

nexus9112 [7]

Answer:

-9,-21

Step-by-step explanation:

let the numbers be x and y and x>y

x-y=12

y=2x-3

x-(2x-3)=12

x-2x+3=12

-x=12-3

-x=9

x=-9

y=2(-9)-3=-18-3=-21

6 is in the ten millions place. The number next to 6 is 1, which is less than 5, so you round down. The nearest 10 million is 60,000,000.

5 over 10 and blank over 100 what’s the faction

uysha [10]

Answer:

50/100

Step-by-step explanation:

So 5/10 is 1/2 and I believe you are implying these are equivalent fractions, so you would have to find half of 100, which is 50.

Hope this helps :)

explain why the given conclusion uses inductive reasoning: 3 + 5 = 8 and 13 + 5 = 18, therefore the sum of two odd numbers is an

egoroff_w [7]

Answer:

Inductive conclusion has been proved to be correct.

Step-by-step explanation:

From the question, we have seen that 3 + 5 = 8

3 and 5 are odd numbers while 8 is an even number.

Which means that the sum of both odd numbers gave and even number.

In the second case, we see that;

13 + 5 = 18

Again,13 and 5 are both odd numbers while 18 is an even number.

Now, Inductive Reasoning is a reasoning that is based on patterns one has observed which would be used to derive a general conclusion. In this question, the pattern observed is that the sum of odd numbers in both cases are equal to an even number.

Thus, we will arrive at a conjecture which is the general conclusion that the sum of 2 odd number is equal to an even number.
