Suppose an infection spreads according to the following data.What type of regression line is the best fit for this data?
A) linear
B) power
C) exponential
D) linear and exponential
Suppose an infection spreads according to the following data. What - 1

Answers

Answer 1
Answer:

Answer-

Exponential regression line is the best fit for the data.

Solution-

Taking

x = input variable,

y = output variable.

Taking the data from the table, regression models were generated using Excel.

As shown in the attachments, the co-efficient of determination (R²) is maximum for Exponential Regression model or more closer to 1.

As,

0.904<0.957<0.974

R^2_{\text{Linear}}<R^2_{\text{Power}}<R^2_{\text{Exponential}}

The more closer the value of R² to 1, the better the regression model and the best fit line is.

In general also, when we consider growth or decay, we follow the exponential function approach.

Therefore, the exponential regression models should be followed and so exponential regression line is the best fit for the data.


Answer 2
Answer: This is exponential and linear. Hope this helps!

4^3 • 5^3 and 20^3, Are the expressions equivalent? Yes or no?

Answers

Hey there!

4^3 * 5^3 = ?

4^3

= 4 * 4 * 4

= 16 * 4

= [64]

5^3

= 5 * 5 * 5

= 25 * 5

= [125]

125 * 64

= [8,000]

20^3

= 20 * 20 * 20

= 400 * 20

= 8,000

8,000 = [8,000]

Therefore, this statement is TRUE so your answer is: [YES]

Good luck on your assignment and enjoy your day!

There are 376 stones in three piles. The second pile has 24 more stones than the first. The third pile has twice as many stones as the second. How many stones in each pile?

Answers

Let the stones of each piles be x, y and z respectively.

thus, x + y + z = 376

x=x
y = x + 24
z= 2y = 2(x+24)

This becomes x + x + 24 + 2(x+24) = 376

= 4x + 24 + 48 = 376

= 4x + 72 = 376

Thus, 4x = 304

Thus, x = 76

and y = 76 + 24 = 100

and z = 2 x 100 = 200

Thus, first pile has 76 stones, second pile has 100 stones and third pile has 200 stones

Answers

-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one

m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one

Answers

i am pretty sure it is B because x is the slope in a graph and 1 can be 1/1 and parrarel means opposite so opposite of x axis is y.
opposite of 1/1 on x axis is opposite of 1/1 on y
