Alenkasestr [34]

Answer:

90% confidence interval for the population mean is between a lower limit of $92.18 and an upper limit of $107.82.

Step-by-step explanation:

Confidence interval for a population mean is given as mean +/- margin of error (E)

mean = $100

sd = $25.20

n = 30

degree of freedom = n-1 = 30-1 = 29

confidence level (C) = 90% = 0.9

significance level = 1 - C = 1 - 0.9 = 0.1 = 10%

critical value (t) corresponding to 29 degrees of freedom and 10% significance level is 1.699

E = t×sd/√n = 1.699×25.20/√30 = $7.82

Lower limit of population mean = mean - E = 100 - 7.82 = $92.18

Upper limit of population mean = mean + E = 100 + 7.82 = $107.82

90% confidence interval is ($92.18, $107.82)

Find the point, M, that divides segment AB into a ratio of 3.1 if A is at (-4,-2) and B is at (4. -10).
Natasha_Volkova [10]

Answer:

The coordinates of M are (2,-8)

Step-by-step explanation:

The coordinates of the point that divides the line segment joining

A(x_1,y_1) to B(x_2,y_2) in the ratio m:n is given by:

(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})

If A is at (-4,-2) and B is at (4. -10) and the ratio is 3:1.

Then

(\frac{3(4)+1(-4)}{3+1},\frac{3(-10)+1(-2)}{3+1})

(\frac{8}{4},\frac{-32}{4})

The coordinates of M are (2,-8)
