In the table, shows' exponential decay is:
The correct option is (A)
We have to find that :
Which table shows exponential decay
From the figure of exponential decay :
When the value of one variable of the function is decreased with increase in the number of other variable, then it is called the exponential decay function with constant exponential coefficient.
It can be given as,
[tex]\frac{dN}{dt}=-\lambda N[/tex]
Here, [tex]\lambda[/tex] is the exponential coefficient.
From Option A:
x y
1 16
2 8
3 4
4 2
The exponential coefficient for first and second row is,
[tex]\lambda=\frac{16}{8}=2[/tex]
Similarly,
[tex]\lambda=\frac{8}{4}=2\\\\\lambda=\frac{4}{2}=2[/tex]
Hence, as all the values of exponential coefficient is same, thus this shown the exponential decay.
From option B:
The exponential coefficient for first and second row is,
[tex]\lambda=\frac{16}{12}=\frac{4}{3}[/tex]
Similarly,
[tex]\lambda=\frac{12}{8}=\frac{3}{2} \\\\\lambda=\frac{8}{4}=2[/tex]

Answer:
slope: 1.25
Part B: The order in which the points are given does not change the value of the slope
Step-by-step explanation:
Part A. Given two points we can find slope using the slope formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Given the points ( -6, 1/2) and ( -4,3 )
We plug in the y values and x values (starting with the last point give )
[tex]m=\frac{3-.5}{-4-(-6)} \\3-\frac{1}{2} =2.5\\-4-(-6)=2\\\frac{2.5}{2} =1.25\\[/tex]
so we can conclude that the slope of a line that passes through the points ( -6, 1/2) and ( -4,3 ) is 1.25
Part B. The order in which the points are given does not change the value of the slope
Observe -
* flip the order in which the points are given *
given (-4,3) and (-6,1/2)
we use the same formula
*plug in the y and x values starting with the last point*
[tex]m=\frac{.5-3}{-6-(-4)} \\.5 - 3=-2.5\\-6-(-4)=-2\\\frac{-2.5}{-2} =1.25[/tex]
The slope still equals 1.25 meaning that the order in which the points are given does not matter.

Two six-sided number cubes are rolled at the same time. What is the probability that the result will have at least one two in it?
(A)7/36
(B)1/5
(C)11/36
(D)1/6
Answer:
1/6
Step-by-step explanation:
There are 12 numbers in total. There is a 2 on each cube so there are two possible chance. 2/12=1/6 2/2=1 and 12/2=6 therefore 2/12=1/6
The solution is, the probability that the result will have at least one two in it is, 1/6.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Two six-sided number cubes are rolled at the same time.
so, we get,
There are 12 numbers in total.
There is a 2 on each cube so there are two possible chance.
2/12=1/6
2/2=1
and 12/2=6
now, we have,
therefore 2/12=1/6.
Hence, The solution is, the probability that the result will have at least one two in it is, 1/6.
