to find X when K is known
divide K by Y
0.6/0.6 = 1
X = 1
Answer:
-2x + 10
Step-by-step explanation:
Distribute -2 to x - 5 to simplify the expression. So we get: -2(x - 5) = -2x + 10.
Answer:
(155.301 ; 159.299)
Step-by-step explanation:
Xbar = 157.3
Sample size, n = 234
Population standard deviation, σ = 15.6
The confidence interval :
Xbar ± standard Error
Standard Error = Zcritical * σ/√n
Zcritical at 95% = 1.96
Standard Error = 1.96 * (15.6/√234) = 1.999
Lower boundary : 157.3 - 1.999 = 155.301
Upper boundary : 157.3 + 1.999 = 159.299
(155.301 ; 159.299)
Answer: B
Step-by-step explanation:
After adding the new data set to the median, we re-arrange in ascending order
23, 26, 26, 29, 30, 33, 40
Median is the midpoint value in the data set, therefore, median is still 29.
I hope this helps.
