How to convey the informationIn statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.
The median is the value in the middle of a data set, meaning that 50% of data points have a value smaller or equal to the median and 50% of data points have a value higher or equal to the median.
The median for A is 25.5 and 26 for B. This implies that B has higher median than A.

CDs are sold at a different price.
2 DVDs and 1 CD cost £35
2 DVDs and 2 CDs cost £45
Martin has £50 Does he have enough to buy 1 DVD and 3 CDs?
Answers
Answer:
Step-by-step explanation:
Lets Price of a DVD is fixed i.e. 15
and One CD price is 5 (Not fixed)
In First situation
2 DVDs and 1 CD cost = 35 as given
2 x 15 + 5 = 35
Lets one CD price is 7.5
In Second situation
2 x 15 + 2 x 7.5 = 45
Its mean CD price may be between 5 to 7.5
In asked scenario, Martin has 50
1 DVD and 3 CDs?
1 x 15 + 3 x 7.5 = 37.5
37.5 is lesser than 50
Hence Martin has enough to buy 1 DVD and 3 CDs.

the specification for the clearance is 0.015 to 0.063 mm. what is the probability that the specification is met?
Answers
To determine the probability that the specification for the clearance is met, we need to assume that the clearance follows a normal distribution. We can then use the standard normal distribution to calculate the probability that a clearance falls within the given specification range.
Assuming a normal distribution, we can use the formula for the standard normal distribution to calculate the probability that a clearance falls within the range of 0.015 to 0.063 mm:
z = (x - μ) / σ
where z is the z-score, x is the value we want to find the probability for, μ is the mean of the distribution (which we assume to be the midpoint of the specification range, i.e., (0.015 + 0.063) / 2 = 0.039 mm), and σ is the standard deviation of the distribution (which we assume to be (0.063 - 0.015) / 6 = 0.008 mm).
Using these values, we can calculate the z-scores for the lower and upper limits of the specification range:
z1 = (0.015 - 0.039) / 0.008 = -3
z2 = (0.063 - 0.039) / 0.008 = +3
We can then look up the area under the standard normal distribution curve between these two z-scores using a standard normal distribution table or a statistical software program. This area represents the probability that a clearance falls within the specification range. The area is approximately 0.9973, or 99.73%.
Therefore, we can say that there is a 99.73% probability that the specification for the clearance is met.

Answers
The solution of the given equation is 2x² - 13x +13.
What is the solution of the equation?
The collection of all values that, when substituted for unknowns, cause an equation to hold true is known as the solution. Two fundamental algebraic rules using the additive property and the multiplicative property are utilized to determine the solutions for equations needing a single unknown raised to a power of one.
What is the simplification rule?
For those sorts of reasoning that deal with conjunctions, the rule of simplification provides a strong argument. This covers natural deduction, predicate logic, and propositional logic.
Here, we have
Given equation 2(x - 2)² - 5(x - 2) - 5
By applying the simplification rule, we get
= 2(x - 2)² - 5(x - 2) - 5
= 2( x² + 4 - 4x ) - 5x +10 - 5
= 2x² + 8 - 8x - 5x + 5
= 2x² - 13x +13
Hence, the solution of the given equation is 2x² - 13x +13.

a local ice cream shop has a special deal on thursdays: buy a waffle cone for $3 and get each scoop of ice cream for $1.50. what would be the rate of change in this word problem?
Answers
In the given word problem, the rate of change is the change in the cost of the ice cream concerning the change in the number of scoops.
That is, the rate of change is the ratio of the change in the cost of ice cream and the change in the number of scoops. Let's first calculate the initial rate of change or slope of the given deal: When we buy a waffle cone, the cost is $3, and we can buy one scoop of ice cream for $1.50.So, for one scoop of ice cream, the total cost would be 3 + 1.50 = $4.50.
We can represent the cost of one scoop of ice cream with the help of a linear equation: y = mx + b. Here, the slope or the rate of change, m = Change in cost of ice cream/ Change in the number of scoops= 1.5/1= 1.5Therefore, the rate of change of the ice cream with respect to the number of scoops is $1.50/scoop.

You're given the rational number 46/224. You can choose to add 10 to the numerator or add 10 to the denominator. Which option will give you a larger final number?
Answers
Adding to the numerator will always increase the final number, adding to the denominator will decrease.
Here’s an example:
1/2, which is 0.5
If you add 5 to the numerator, it will be 6/2, or 3/1, which is 3. If you add 5 to the denominator, it will be 1/7, which is 0.143.
Hope this helped!
Answer:
Therefore, adding 10 to the numerator is the better option if we want to increase the value of 46/224.
Step-by-step explanation:
To find which option will give a larger final number, we should calculate both the possibilities and compare them ,
Firstly,add 10 to the numerator
Now,
The new rational number will be,
(46 + 10) / 224
= 56 / 224
= 7 / 28
2ndly,
Add 10 to the denominator
The new rational number will be,
46 / (224 + 10)
= 46 / 234
After comparing these two rational numbers and converting them to decimals or simplify them ,
7 / 28
= 0.25
46 / 234
= 0.196581...
Since 0.25 is larger than 0.196581...,
Now,adding 10 to the numerator will result in a larger final number.
Therefore, adding 10 to the numerator is the better option if we want to increase the value of 46/224.
ji-min needs to replace a circular window having a diameter of 5 ft. she decides to use double strength glass costing 3 per square foot. find the total cost for the glass.
Answers
The total cost for the glass needed to replace the circular window with a diameter of 5 ft using double strength glass costing $3 per square foot will be $58.89.
The total cost for the glass needed to replace the circular window with a diameter of 5 ft can be calculated by finding the area of the circular window first. The formula for the area of a circle is A=πr^2, where r is the radius of the circle. In this case, the diameter is given as 5 ft, so the radius will be half of that, which is 2.5 ft.
Using the formula, we can calculate the area of the circular window as follows:
A = πr^2
A = π(2.5 ft)^2
A = 19.63 sq ft
Therefore, the total cost of double strength glass for the circular window will be:
Total cost = Cost per sq ft x Area
Total cost = $3 x 19.63 sq ft
Total cost = $58.89
So, the total cost for the glass needed to replace the circular window with a diameter of 5 ft using double strength glass costing $3 per square foot will be $58.89.

A parallelogram has a height of x cm. The length of its base is 4 cm greater than its height. A triangle has the same height as the parallelogram. The length of the triangle’s base is 20cm.
What is the value when the triangle and the parallelogram have the same area?
Answers
The value of x when the triangle and the parallelogram have the same area is 6 units
The dimensionsThe dimension of the parallelogram is given as:
Height = xBase = 4 + xThe dimension of the triangle is given as:
Height = xBase = 20AreasThe area of a shape is the amount of space it occupies
The area of the parallelogram is calculated as:
\(Area = x (4 + x)\)
The area of the triangle is calculated as:
\(Area = 0.5 \times 20 \times x\)
\(Area = 10x\)
Both areas are equal.
So, we have:
\(x(4 + x) = 10x\)
Divide both sides by x
\(4 + x = 10\)
Subtract 4 from both sides
\(x =6\)
Hence, the value of x is 6 units
