Answer:
Justin has a lower mean tip for the week with $42.
Step-by-step explanation:
To find the mean you must add all the numbers and then divide the sum by how many numbers there are.
For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.
As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.
46 is greater than 42 so Justin has the lower mean.
Answer:
x = -5
, y = 1
Step-by-step explanation:
Solve the following system:
{3 x + y = -14 | (equation 1)
-2 x - y = 9 | (equation 2)
Add 2/3 × (equation 1) to equation 2:
{3 x + y = -14 | (equation 1)
0 x - y/3 = (-1)/3 | (equation 2)
Multiply equation 2 by -3:
{3 x + y = -14 | (equation 1)
0 x+y = 1 | (equation 2)
Subtract equation 2 from equation 1:
{3 x+0 y = -15 | (equation 1)
0 x+y = 1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -5 | (equation 1)
0 x+y = 1 | (equation 2)
Collect results:
Answer: {x = -5
, y = 1

Answer:
Correct choices are 1 and 4
Step-by-step explanation:
As per data given we have:
- Median temperature is 75°F and 88°F
- And the range from the median is 5° for both cities
This gives us lowest temperatures of:
- 75° -5° = 70° and 88° - 5°= 83° respectively
And high temperatures are:
- 75° + 5° = 80° and 88° + 5° = 93°
<u>Answer choices based on above details:</u>
- Choice 1 - correct
- Choice 2 - incorrect. Correct answer is 93°
- Choice 3 - incorrect. Correct answer is 93° - 70° = 23°
- Choice 4 - correct
