<u>Corrected Question</u>
Below is data collected from a random sample of 80 students regarding their fitness habits. If the entire school has 600 students, then what is a reasonable estimate for the number of students who consider themselves to have an average fitness habits.
Answer:
(D)330
Step-by-step explanation:
Out of a random sample of 80 students
44 considered themselves to have AVERAGE fitness habits.
Relative Frequency of Students with average fitness habits=44/80
Therefore, out of the total population of 600 students
Expected Number of Students with average fitness habits
=Relative Frequency of Students with average fitness habits X Total Population
<u>The correct option is D.</u>
Answer:
y = - 3x + 6
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 )
Rearrange x - 3y = 5 into this form
Subtract x from both sides
- 3y = - x + 5 ( divide all terms by - 3 )
y = 
x - 
← in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 3
Note the line crosses the y- axis at (0, 6) ⇒ c = 6
y = - 3x + 6 ← equation of perpendicular line

Answer:
Option (3)
Step-by-step explanation:
We have to divide polynomial given as (x³ - 21x² + 147x - 343) by (x - 7) by synthetic division.
7 | 1 -21 147 -343
<u> ↓ 7 -98 343 </u>
1 -14 49 0
Therefore, quotient is (x² - 14x + 49) and the remainder will be 0.
Option (3) will be the answer.
The answer is 3 + 2k
This is because multiplying by 1/5 is like dividing each term by 5
10k + 15 = 5 • (2k + 3)
