Answer:
The interquartile range(IQR) is <u>31</u>.
Step-by-step explanation:
Given:
A distribution has the five-number summary shown below:
24, 36, 42, 57, 65.
Now, to find the interquartile range (IQR).
So, to get the IQR we need to find the quartile 1 and quartile 3:
As, 42 is the median.
Quartile 1 is the average of first half.
<u>24, 36</u>, 42, 57, 65.
Q1 =
Q1 =
Q1 =
Quartile 3 is the average of last half.
24, 36, 42, <u>57, 65</u>.
Q3 =
Q3 =
Q3 =
Thus, by putting the formula we get IQR:
IQR = Q3 - Q1.
Therefore, the interquartile range(IQR) is 31.

Answer:
y = - x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
14x + 6y = 36 ( subtract 14x from both sides )
6y = - 14x + 36 ( divide all terms by 6 )
y = - x + 6, that is
y = - x + 6 ← in slope- intercept form
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
3
Using (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 3, 6)
m = =
= - 2
Since the line passes through the origin (0, 0) then y- intercept is 0
y = - 2x ← equation of line
4
let (x₁, y₁ ) = (6, 0) and (x₂, y₂ ) = (0, 3)
m = =
= -
note the line crosses the y- axis at (0, 3) ⇒ c = 3
y = - x + 3 ← equation of line
5
let (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (-2, - 3)
m = =
= 3
note the line crosses the y- axis at (0, 3) ⇒ c = 3
y = 3x + 3 ← equation of line
Answer: 7/8
Cos2x has 3 formulas, Sinx is given in the question, we should use the formula with sinus. I guess that's the solution.
