Option C:
Mean = 2.31
Solution:
Given data:
Number (x) : 0 1 2 3 4
Frequency (f) : 5 15 22 40 6
To find the mean of the given data:
= 2.306
= 2.31
Mean = 2.31
Option C is the correct answer.
Answer:
D
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 )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table
m = = -
The line crosses the y- axis at (0, 28 ) ⇒ c = 28
y = - x + 28 ← equation of line → D
Answer:
8 feet
Step-by-step explanation:
You would use the Pythagorean theorem to find it.
a^2 + b^2 = c^2
Therefore:
6^2 + b^2 = 10^2
36 + b^2 = 100
-36 -36
b^2 = 64
Square root both sides
b = 8
Answer:
Permutation
Step-by-step explanation:
The term to describe the given statement is permutation.
When defining permutation, certain keywords such as order does matter and arrangement are used to describe permutation.
Take for instance:
<em>The arrangement of 3 boys on a seat</em>
<em>Ways 4 friends can sit to take photographs</em>
<em />
...are examples of permutation
Permutation of r objects in n distinct objects is calculated as:
