Answer:
a
Step-by-step explanation:
it has to have to same slope as the first equation so you have y=5x+b then what you do is plug in the points and solve for b. which gives you 2. so your final equation is y=5x+2
7=5+b
-5 -5
2=b
Answer: x=7/5 or 1 2/5
Step-by-step explanation:
Given
x+3/5=2
Subtract 3/5 on both sides
x+3/5-3/5=2-3/5
x=10/5-3/5 (This is to convert 2, as a integer, to a fraction in order to ease the
x=7/5 operation)
10; you can buy ten cartridges because 140/14 is of course 10. Feedback is appreciated :-)
Answer:
a 0.20
Step-by-step explanation:
The standard error of the mean can be calculated using the formula
SE= where
- s is the population standard deviation of the time spend on the computer (1.4 hours)
- N is the sample size of the data collected. (49)
Using the numbers SE= =0.20
