Answer:
Hi Christine
Step-by-step explanation:
Ms. Paik would be mad, wouldn't she?
Answer:
If we are working in a coordinate plane where the endpoints has the coordinates (x1,y1) and (x2,y2) then the midpoint coordinates is found by using the following formula:
midpoint=(x1+x22,y1+y22)
Step-by-step explanation:
The answer to this is 39 and 27
Answer:
3.113, 4.507
Step-by-step explanation:
From the given values:
Mean = 3.81
Standard deviation = 1.74
Therefore
M = √(1.72/18) = 0.4
μ = M ± t(sM)
μ = 3.81 ± 1.74*0.4
μ = 3.81 ± 0.697
Recall that the mean is estimated at 90% confidence level,
Hence,
= 90% CI [3.113, 4.507]
Answer:
The equation would be y = 1.5x + 0.5
Step-by-step explanation:
To find the equation of the line, use the point and the slope in point-slope form.
y - y1 = m(x - x1)
y - 32 = 1.5(x - 21)
y - 32 = 1.5x - 31.5
y = 1.5x + 0.5
