Answer:
1,670
Step-by-step explanation:
35x8= 280
1950-280= 1,670
Answer:
(5.240 ; 8.760)
Step-by-step explanation:
Given :
Sample mean, xbar = 7
Standard deviation, s = 2.29
Sample size, n = 9
95% confidence interval for the population mean :
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 0.05 ; df = 8 = 2.306
Margin of Error = 2.306 * 2.29/sqrt(9)
Margin of Error = 1.760
Lower boundary = (7 - 1.760) = 5.240
Upper boundary = (7 + 1.760) = 8.760
(5.240 ; 8.760)
Answer:
Y = 50x
Step-by-step explanation:
Remember that slope intercept form is Y = mx + b indicating that m is the slope
To solve this equation use the formula
Y2 - y1 , x2 - x1:
50 - (- 50) = 100
25 - (-25) = 50
100/50 = 50/1
So the answer is y = 50x
