Suppose events A and B are independent and P(A and B) is 0.2
Which statement could be true?
(1) P(A) = 0.4, P(B) = 0.3, P(A or B) = 0.5
(2) P(A) = 0.8, P(B) = 0.25
(3) P(A/B) = 0.2, P(B) = 0.2
(4) P(A) = 0.15, P(B) = 0.05
Answer: answer choice 2) P(A) = 0.8, P(B) = 0.25
Step-by-step explanation:
The True statement is P(A) = 0.8, P(B) = 0.25.
The correct option is (B).
What is Conditional Probability?Conditional probability is a measure of the probability of an event occurring, given that another event has already occurred.
1. 0.4 ·0.3≠ 0.2,
2. 0.8 · 0.25 = 0.2
3. P(A|B)= P(A)= 0.2
0.2 ≠ 0.2 · 0.2
4. 0.2 ≠ 0.15 · 0.05
Hence. the only condition is satisfied is (B).

Please help!!!you must use the desmos caculator
Part (a)
Open up Desmos and click on the button that looks like a plus sign. It's at the upper left corner. We're going to want to add a table.
Type all of the values into the table. This table is stacked vertically compared to yours which is laid out horizontally. It's the same thing pretty much. It depends on your preference on which you like better.
After the data values are typed in (which is a bit of a tedious process if you ask me), you'll then move to the next input box to type the following
[tex]y_1 \sim mx_1 + b[/tex]
Type it in exactly as you see it. To get the small '1's as subscripts, you'll need to use an underscore. So you'll type y_1 to mean [tex]y_1[/tex]
The ~ symbol is likely found in the upper left portion of your keyboard.
After typing that into the second input box, you should get what you see in the screenshot below.
The parameters your teacher wants are the m and b values.
Desmos is showing these values:
m = 0.125873b = -7.11916These values are approximate. As the instructions state, do not round the values mentioned.
Therefore, we go from y = mx+b to y = 0.125873x-7.11916 approximately
This is the regression line. It is the closest line to all of the points.
Answer: y = 0.125873x-7.11916===========================================================
Part (b)
The year 2022 is 2022-1900 = 122 years after the year 1900.
This means we'll plug x = 122 into the regression equation to find the predicted value for y.
y = 0.125873x-7.11916
y = 0.125873*122-7.11916
y = 8.237346
I used the Desmos input box as a calculator. Simply type in 0.125873*122-7.11916 exactly as you see it and it should produce the value 8.237346
That then rounds to 8.24
We predict in the year 2022, the minimum wage should be about $8.24
This is an estimated value because the regression line isn't perfect. In fact, the further we move away from the main known points, the worse off the estimation will likely get. This is why extrapolation could be a bad idea. However, it's a fairly good way to see what's going on.

I don't get what I'm doing wrong,does anybody know this?The diameter of a great circle is 24 inched find the total surface area of the hemisphere don't forget to include the base in the total area.
since it's diameter is 24, its radius must be 12.
[tex]\textit{surface area of a sphere}\\\\ SA=4\pi r^2 ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=12 \end{cases}\implies SA=4\pi (12)^2\implies SA=576\pi[/tex]
now, that's for a sphere, for a hemisphere with the same radius it'd just be half that or 288π, now let's add the area of the circular base.
[tex]\stackrel{\textit{\LARGE Areas}}{\stackrel{hemisphere}{288\pi} ~~ + ~~\stackrel{circular~base}{\pi (12)^2}}\implies 288\pi ~~ + ~~144\pi \implies 432\pi[/tex]
The total surface area of the hemisphere is 288π. The area that include both surface area of hemisphere and the base of the total area is 432π.
What is hemisphere?
A hemisphere is "half the part of sphere".
According to the question,
The diameter of greater circle is 24 this implies radius of circle is 12.
Surface area of sphere = 4πr²
= 4×π × (12)²
= 576π.
Surface area of sphere is 576π
Surface area of Hemisphere is half of the surface area of sphere.
(576π)/2 = 288π
In order to include the base in the total area only if add surface area of hemisphere and area of circle.
surface area of hemisphere + rea of circle = 288π + π(r)²
= 288π + π(12)²
= 288π + 144π
= 432π
Hence, the total surface area of the hemisphere is 288π. The area that include both surface area of hemisphere and the base of the total area is 432π.

The function that represents the data in the table is y=2x²-3
What is a function?A relation is a function if it has only One y-value for each x-value.
Let us check the function of the given data by plugging any ordered pair in the given functions
Let us take a point (1, -1) to check each function
(a) y=x/2-3
-1= 1/2-3
-1=-5/2
So y=x/2-3 is not the function
(b) y=2ˣ-3
-1=2-3
-1=-1
Now let us check for other point
5=4-3
5=1
This function is not satisfied for all points
(c) y=2x-3
-1=-1
For point (2, 5)
5=-1
This function is not satisfied for all points
(d) y=2x²-3
-1=2-3
-1=-1
Now 5=8-3
5=5
Hence, the function that represents the data in the table is y=2x²-3

{3, 4, 5, 6}
Step-by-step explanation:Inequalities represent the value of a variable by comparing them to other values.
Inequality Signs
Before answering the question, make sure you understand the different inequality signs.
< - This sign represents less than. This means that the value on the left is less than the value on the right.> - This sign represents greater than. This means that the value on the left is greater than the value on the right.< - This sign means less than or equal to. So, the value on the left will be less than or the same as the value on the right.> - This sign means greater than or equal to. So, the value on the left will be greater than or the same as the value on the right.Solving the Inequality
To make this question easier to answer, we can solve the inequality. Solving an inequality involves isolating the variable.
To do this subtract 19 from both sidesx < 9Finding the Set
Now that we solved the inequality we can look for the correct set of numbers. Since we solved the inequality, we know that all of the correct values should be less than 9. However, because there was no equal to sign, 9 is not included in the set. The only set that has only correct solutions is {3, 4, 5, 6}.
