The statement that describes how each person observes the speed of the football is both Alex and his friend observe it as 10 m/s.
To answer the question, we need to know what speed is.
What is speed?Speed is the distance moved per unit time
Since Alex is standing still and throws a football with a speed of 10 m/s to his friend, who is also standing still. If there were relative motion between Alex and his friend, that is Alex or his friend were moving, each person would observe a different speed for the football.
Since there is no relative motion between Alex and his friend, they both observe the same speed for the football.
So, both Alex and his friend observe it as 10 m/s.
So, the statement that describes how each person observes the speed of the football is both Alex and his friend observe it as 10 m/s.

Find the value of the given equation : 2 (x-1) - 6 =24
what is the interquartille range of the given data set
11, 12, 14, 15. 18. 19. 21, 23. 25, 55
A. 25
B. 9
C. 44
Answer: B. 9
Step-by-step explanation:
First, find the median of the data set. This set has an even number of points, so find the average between the two middle points: 18 and 19. 18+19 = 37. 37/2 = 18.5. The median is 18.5.
Now, to find the lower quartile, find the median of the lower half of the data set {11, 12, 14, 15, 18}. The number in the middle is 14. The lower quartile is 14.
To find the upper quartile, find the median of the upper half of the data set {19, 21, 23, 25, 55}. The number in the middle is 23. The upper quartile is 23.
To find the interquartile range, subtract the lower quartile from the upper quartile. 23-14 = 9. The interquartile range is 9.
A shop sells apples and oranges in the ratio 5:2.
It sells apples for 30p and oranges for 40p.
If the shop sells 35 pieces of fruit altogether, how much money does the shop receive? Give your answer in
pounds and pence.
Total money does the shop receive is 0.12 Pound
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
According to the question
A shop sells apples and oranges in the ratio 5:2
Let constant multiple of the ratio as a
Now,
Apples = 5a
Oranges = 2a
Total pieces of fruit sell = 35
i.e
5a + 2a = 35
7a = 35
a = 5
Therefore,
Apples = 5*5 = 25
Oranges = 2*5 = 10
Now ,
Shop sells apples at = 30p
Shop sells oranges at = 40p
Total money the shop receive = 30 * 25 + 40 * 10
= 1150 p
Paisa to Indian rupee : 100p = ₹1
= ₹11.50
Now, Indian rupee to pounds :
1 Indian Rupee equals 0.011 Pound (according to current market value)
₹11.50 is equal to 0.12 Pound
Hence, Total money does the shop receive is 0.12 Pound .

Work out the probability that the total of the two numbers is more than 32
The probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]
What is probability?"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."
Formula of the probability of an event A is:P(A) = n(A)/n(S)
where, n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.
What is the formula of combination?[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
For given question,
We have been given five number cards.
Two of the five cards are picked at random.
Using combination formula the possible number of outcomes would be,
[tex]^5C_2\\\\=\frac{5!}{2!(5-2)!} \\\\=10[/tex]
So, n(S) = 10
Let event A : the total of the two numbers is more than 32
A = {(19, 14), (19, 22), (13, 22), (14, 22)}
So, n(A) = 4
Using the formula for probability,
[tex]\Rightarrow P(A)=\frac{n(A)}{n(S)} \\\\\Rightarrow P(A)=\frac{4}{10}\\\\\Rightarrow P(A)=\frac{2}{5}[/tex]
Therefore, the probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]

Answer:
the cost of the textbook was $173.14 before the tax was added
Step-by-step explanation:
6.75% of $185.67 is 0.0675 x $185.67 = $12.53
$12.53 is 6.75% of $185.67
sine $185.67 is the total AFTER we subtract the amount
$185.67 - $12.53 = $173.14

Question Number 2 of 20 - Algebra I
Which is an example of the commutative property of addition?
3+5m=5m+3
3+5m=(3+5)m
3+ 5m= 3 + (1 + 4)m 3+5m=3m+5
Answer:
3 + 5m = 5m + 3What is the communitive property of addition?The commutative property of addition means that it does not matter what order in which you add numbers. You will get the same answer either way. It is represented as a + b = b + a, in which a and b are real numbers. However, the property is not limited to two numbers.
How would the communitive property of addition be applied to the expression 3 + 5m = 5m + 3?1) Rearrange terms
3 + 5m = 5m + 3
5m + 3 = 5m + 3
2) Subtract 3 from both sides
5m + 3 = 5m + 3
5m + 3 - 3 = 5m + 3 - 3
3) Simplify
- Subtract the numbers
5m + 3 - 3 = 5m + 3 - 3
5m = 5m + 3 - 3
- Subtract the numbers
5m = 5m + 3 - 3
5m = 5m
4) Subtract 5m from both sides
5m = 5m
5m - 5m = 5m - 5m
5) Simplify
- Combine like terms
5m - 5m = 5m - 5m
0 = 5m - 5m
- Combine like terms
0 = 5m - 5m
0 = 0
This means it has infinite solutions.
But the commutative property addition have been shown.

Step-by-step explanation:
The surface area for rectangular prisms is: S = 2lw + 2lh + 2wh, where l = length, w = width, h = height.
Substitute the known values into this equation: h = 5, l = 10, w = x, S = 178
178 = 2(10x) + 2(5 x 10) + 2 (5x)
Simplify!
178 = 20x + 100 + 10x
Subtract 100 from both sides and combine x's
78 = 30x
divide both sides by 30
x = 2.6 m
answer check: 2(10 x 2.6) + 2(5 x 10) + 2 (5 x 2.6) = 178 (true!)
