Answer: 311 pounds
Step-by-step explanation:
To find the average, add up all of the values and divide by the amount of values.
First add up all of the values.
322+290+321+326+330+315+311+292+290 = 2797
Now count how many values there are and divide your previous sum by it.
2797/9 = 310.78
Because you need to have 3 sig figs, round to the nearest one.
310.78 rounds up to 311.
answer-311
Step-by-step explanation:
322+290+321+326+330+315+311+292+290=2797
Count the number of values and divide by 2797
2797 divided by 9 =310.77777777777777
Nearest one-311
Answer:
(a) 3x -y = 7
(b) x +3y = 29
Step-by-step explanation:
(a) The standard form of the given line is ...
3x -y = 5
The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...
3x -y = 3(5) -(8)
3x -y = 7
__
(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).
x + 3y = (5) +3(8)
x + 3y = 29
Answer:
Interest =$7540
Step-by-step explanation:
p=$13000
r=5.8%
t=10yrs
i=p*r*t/100
=13000*5.8*10/1000
=130*58
= $7540
Explain A. What expression can be written to represent how many yards the football team is from where it started? Explain your reasoning.
Explain B. How many yards is the football team from where it started?
Explain C. Suppose that, instead, the football team had gained 9 yards on its first play and lost 9 yards on its second play. Would the team’s position on the field have been any different than it actually was after the first two plays? Why or why not
