Two of the five cards are picked at random.
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]

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 .

The cylinder is a three-dimensional shape, and the base area of the cylinder is 12π square feet
How to determine the base area?The given parameters are:
Volume = 216π cubic feetHeight = 18 feet.The volume of a cylinder is calculated using:
Volume = Base area * Height
So, we have:
216π = Base area * 18
Divide both sides by 18
Base area = 12π
Hence, the base area of the cylinder is 12π square feet

This table shows the ticket price for each person to visit a zoo in winter.
adult = £18
child (3-17) = £14
child ( under 3) = free
A family of two adults, one child aged 8 and one child aged 1 visit the zoo in winter.
In summer, the zoo increases the prices.
An Adult ticket increases by 20%.
A Child ticket increases by 15%.
How much more does it cost the family to visit in the summer than in the winter?
Answer: £9.3 more
Step-by-step explanation:
Price for winter tickets: £18 + £18 + £14 = £50
Summer tickets pricing:
£18 + 20% = £21.6
£14 + 15% = £16.1
Price for summer tickets: £21.6 + £21.6 + £16.1 = £59.3
Subtract winter tickets from summer tickets for difference:
£59.3 - £50 = £9.3

Answer:
2.6 m
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!)

Ambition Succeswhat 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.

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

What is the Mean and Median of a Data Set?Mean = sum of data points / number of data points.
Median = center/middle of the data distribution.
Mean for Julia = (20 + 20 + 30 + 60 + 60 + 60 + 70 + 70 + 100 + 100 + 100 + 115 + 115 + 115)/14 = 69.6
