Answer:
Option E
Step-by-step explanation:
This survey will not be reliable as it is chosen for convenience; the first 120 students to arrive in school on a particular morning and this collection of individuals may not be a representative of the population. The study may become biased because it does not take into account the latecomers among the students which might have been changed the study from systematically favoring certain outcomes.
Answer:
(5,-2)
Step-by-step explanation:
9x+5y=35
2x+5y=0
Multiply the second equation by -1
-1 (2x+5y) = 0*-1
-2x-5y = 0
Add the first equation and the modified second equation
9x+5y=35
-2x-5y = 0
-------------------
7x = 35
Divide by 7
7x/7 = 35/7
x = 5
Now we need to find y
2x+5y = 0
Substituting in x
2(5) +5y = 0
10 +5y = 0
Subtract 10
10-10 +5y = -10
5y = -10
Divide by 5
5y/5 = -10/5
y = -2
(5,-2)
29.10 or 29.1 is the answer rounded to the nearest hundreth
Answer:
y=1/2x -2. Hope this helps!
Answer:
2/5 = 6/15
1/3 = 5/15
Step-by-step explanation:
LLCD of 5 and 3 is 15.
So 2/5 = 2*3/15 = 6/15
and
1/3 = 5*1 / 15 = 5/15
