What is a probability distribution?For a particular data generation process, a probability distribution represents the predicted outcomes of various values. The mean, standard deviation, skewness, and kurtosis are all features of probability distributions, which are characterized by the mean, standard deviation, skewness, and kurtosis.
The mean of the probability distribution is determined by the given formula,
[tex]\mu = \sum (x\times P(x))[/tex]
Now, substituting the value to know the probability distribution, we will get,
[tex]\mu = (1 \times 0.1)+(2 \times 0.2)+(3 \times 0.4)+(4 \times 0.2)+(5 \times 0.1)\\\\\mu = 0.1+0.4+1.2+0.8+0.5 = 3[/tex]
Hence, the mean of the probability distribution is 3.

Step-by-step explanation:
The answer is 2 3/4
9 8/12 - 4 9/12
Simplest form please
Answer:
1/3
Step-by-step explanation:
were going to subtract the wholes so what is 9-9=? it =02. Now we know we have 0 wholes. Next what is 8 -4=? 8 -4=4
3. Now our fraction is 4/12 now since 4 x 3 =12 then that means it's the first number besides 3 so what I mean about that is it is 1/3 but if the fraction were 8/12 then it would be 2/3 but it is 4/12 so it is 1/3.
4. That is our answer and were finished the final answer is 1/3 or 33.333

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle. What is the length of the rectangle? 0. 75 units 1. 5 units 3 units 6 units.
By using the given condition, the length of the rectangle is 6 units.
It is given that
Area of the rectangle = 9 square units
Width of the rectangle = 1/4 of length
What is the area of a rectangle?The area of a rectangle is the multiplication of its length to width.
Let us take the length of the rectangle as l
So, the width of the rectangle will be l/4
Area of the rectangle,
[tex]l*\frac{l}{4} = 9(given)[/tex]
[tex]l^{2} = 36\\l = 6[/tex]
Therefore, the length of the given rectangle is 6 units,

Jon = 1020
Bon = 2380
Please help, thanks.
Answer:
2. b) New amount = £6200
Same ratio → Jon : Bon = 3 : 7
6200 ÷ (3 + 7) = 620
⇒ 620 × 3 : 620 × 7
⇒ 1860 : 4340
Jon = £1860
Bon = £4340
3.
Tom : Thom : Thomas
= 2 : 3 : 5
= 2x: 3x : 5x
Given Tom received £2400:
⇒ 2x = 2400
⇒ x = 1200
2x: 3x : 5x
⇒ (2 × 1200) : (3 × 1200) : (5 × 1200)
⇒ 2400 : 3600 : 6000
Tom = £2400
Thom = £3600
Thomas = £6000

cats : dogs
= 1 : 5
= 1x : 5x
Given there are 8 cats:
⇒ 1x = 8
⇒ x = 8
1x : 5x
⇒ (1 × 8) : (5 × 8)
⇒ 8 : 40
Therefore, there are 40 dogs

in 2 hours. How many
boxes can she pack in
his 8-hour shift?
boxes
Answer:
Answer 100
Step-by-step explanation:
so if they can pack 25 boxes in 2 hours then you can do 8/2 which would equal four then 4*25 to get 100. You would do the division of 8 by two because you have 8 hours and it take 2 for 25 boxes.
Answer:
100 boxes
Step-by-step explanation:
25/2 to find how many boxes in one hour which is 12.5. Then, multiply that by 8 to get 100.
BRAINLIEST (will mark) Given that the point $(4,7)$ is on the graph of $y=f(x)$, there is one point that must be on the graph of $2y=3f(4x)+5$. What is the sum of the coordinates of that point?
Answer: mark me brainliest!!
2y = 3f(4x) + 5 divide through by 2 y = (3/2) f(4x) + 5/2
The "4x" part compresses the graph horizontally by a factor of 4The "3/2" part vertically stretches the graph by a factor of 3/2The "5/2" part shifts the resulting point up by 5/2 units Applting the first two to (4,7) we get (4*(1/4) , 7* (3/2) ) = ( 1, 21/2)
Applying the last one, we arrive at ( 1, 21/2 + 5/2) = (1, 26/2) = ( 1,13)
The sum of the coordinates is 1 + 13 = 14

Which of the following proves triangles are congruent
Answer:
SAA
Step-by-step explanation:
This is because we see the triangles share two equal congruent angles and the one side where they touch each other. We don't know anything about the other sides so it cannot be ASA.
The two right-angled triangles are congruent by RHS so the correct option is neither.
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
From the given figure two triangles share a common side which is their height.
The two triangles have the same measure of angles opposite to their base,
Therefore the bases of the triangles are also congruent.
Now, we know if two right-angled triangles have the same height and base
their hypotenuse must also be the same.
Now, the hypotenuse and one of the legs of the triangle is congruent to another right-angled triangle they are congruent by RHS or right-angled hypotenuse.

Find the area of the composite figure.
Answer:
42cm
Step-by-step explanation:
I'm sry if I'm wrong
Answer:
42 square centimeters
Step-by-step explanation:
We know all the sides of the square is 6 cm.
The side of a square and the triangle on the bottom add to 8 cm.
The bottom part of the triangle must be 2 cm.
The area of the square is 36 square centimeters as we use the formula Area = side x side for a square.
The height of the triangle is 6cm as it is as tall as the square.
The formula of a triangle is 1/2 * base * height.
1/2*(6)*(2) = 6 square centimetes.
Adding the two together,
36 + 6 = 42

Ram is 1 m 10 cm tall and Shyam is shorter by 20 cm. Find the height of Shyam
Shyam is 0.9 m
Step-by-step explanation:
10 cm = 10/100 m = 0.1 m
Now,
Ram = 1m + 0.1 m = 1.1 m
Now,
shyam = 1.1 m - 20 cm
= 1.1 m - 20/100 m
= 1.1 m - 0.2 m

The goal of this is to get 24 by multiplying the p value with q. q can be any number, as long as it gets to 24 in this scenario.
So your first p value is 4, so you can take 24, and divide it by 4 to get your answer.
24/4=6 then you can check it by multiplying 6*4=24. That means 6 is your first q value.
This will work for the rest of them in that table, except for the 0, because no matter what you multiply that by you cannont get 24. Try it out for yourself, goodluck!
Answer:
q- 24/4=6
24/2=12
24/0=0
24/-2= -12
24/-4= -6

On Monday Mrs. Wise bought 3 lbs of apples at $4 per lb. On Tuesday, apples were on sale for 20% off so she bought another 5 lbs.
What is the price of apples on tuesday?
Answer:
The average price for all apples Mrs. Wise bought is $1.5 and this can be determined by using the unitary method.
Step-by-step explanation:
Given :
On Monday Mrs. Wise bought 3 lbs of apples at $4 per lb.
On Tuesday, apples were on sale for 20% off so she bought another 5 lbs.
If the price of 3 lbs apples is $4 then the price of 5 lbs apples is:
= $20/3
Now, determine the price of apples Mrs. Wise bought on Tuesday when apples are on 20% sale.
= $16/3
The average price is given by:
Average Price = $1.5
So, the average price for all apples Mrs. Wise bought is $1.5.
