Answer:
a) 40 is the interquartile range
descriptive statistics, the interquartile range, also called the midspread, middle 50%, or H‑spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q₃ − Q₁.
b).
The first thing you always need to do before estimating fractions is to round each fraction either to the nearest 0, 1/2, or 1. Example #1. Estimate 3/7 + 5/9. Notice that 3/7 is close to 1/2 and 5/9 is also close to 1/2. Therefore, an estimate for 3/7 + 5/9 is 1/2 + 1/2 = 1.

Answer:
7.5
Step-by-step explanation:
Median = middle number in terms of value
To make it easier to identify the middle number lets list the number from least to greatest
1, 4, 4, 7, 8, 8, 10, 15
Now we can simply find the middle number
We notice that there are two middle numbers as there is an even amount of numbers
Those two numbers being 7 and 8
When finding the median, if there are two middle numbers, you simply add the two numbers together and divide the sum by two to get the median.
So median = 8 + 7 = 15 / 2 = 7.5
Answer:
7.5
Step-by-step explanation:
The median of a set of numbers is the middle number, so we have to order them first from least to greatest. The order would be 1, 4, 4, 7, 8, 8, 10, 15. You can see that there are an even number of numbers, so if we take the two numbers in the middle of the order (7 and 8) and add them to get 15 and divide 15 by two, we get an answer of 7.5.

Step-by-step explanation:
Given
x² + 7x + 10
Consider the factors of the constant term (+ 10) which sum to give the coefficient of the x- term (+ 7)
The factors are + 2 and + 5 , since
5 × 2 = + 10 and 2 + 5 = + 7 , then
x² + 7x + 10 = (x + 2)(x + 5) ← in factored form

The function that represents the exponential graph is, [tex]y = 2^{x+2} + 3[/tex].
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
We know a function is called an exponential function when the exponent is the independent variable, For example, aˣ.
From the graph of the function, When x = 0, y = 7.
Observing the options we have,
[tex]y = 2^{x+2} + 3[/tex].
When x = 0.
[tex]y = 2^{0+2} + 3.[/tex]
[tex]y = 2^{2} + 3.[/tex]
y = 7.

In a carnival game, players get 5 chances to throw a basketball through a hoop. If 7 out of 20 players made all 5 baskets, how many players out of 400 would you expect to make all 5 baskets?
Answers
=====================================================
Work Shown:
7/20 = 0.35 = 35% of the 20 players made all five baskets.
If this trend holds up, then we should expect 35% of the 400 people to make all five baskets.
35% of 400 = 0.35*400 = 140
We expect about 140 people will make all five baskets.
Note how 140/400 = 0.35 = 35%
-------------
Through another alternative method, we can solve like this
7/20 = x/400
7*400 = 20*x ... cross multiply
2800 = 20x
20x = 2800
x = 2800/20 ... dividing both sides by 20
x = 140 which is the same result as before

If f (n)= - 3n + 2, what is the value of f(12) ?
Answers
Answer:
Step-by-step explanation:
f(n)= -3n + 2
to find :f(12)
substitute 12 in place of n
f(12)= -3*12 + 2
f(12)=-36 + 2
f(12)= -34
The value of the f(12) is equal to -46 where the expression is
f(n) = -3n + 2.
What is an expression?Any mathematical statement which consist of numbers , variables and arithmetic operations is known as expression. An expression gives some numerical value when we put the value of variables in it.
Here, f(n)= -3n + 2 is the given expression.
So, we can find the value of f(12) by putting n=12 in f(n).
Put n=12 in f(n), we get
f(12)= (-3)×12 + 2
= -48 + 2
= -46
Hence, the value of f(12) is -46.

Answers
Answer:
The area of the label is 176,000 cm²
Step-by-step explanation:
The given parameters are;
The radius of the cylindrical container, r = 14 cm
The height of the cylinder, h = 20 m
The area covered with the label = The curved surface of the cylinder, A
The curved surface area of a cylinder, A = 2 × π × r × h
π = 22/7
∴ The curved surface area of the cylinder = A = 2 × 22/7 × 14 × 2000 = 176,000
A = 176,000 cm²
∴ The area of the label = The curved surface area of the cylinder = 176,000 cm².
