Answer:

the answer is -153

Step-by-step explanation:

350-200(she paid off 200$)=150

150+23(she charged her account 23$)=173

173-35(she paid off 35$)=138

138+15(she charged her account 15$)=135

her new balance is -153$ because that is how much she has left to pay off before she reaches 0 then she can gain credit.

Answer:

$147

Step-by-step explanation:

It is $147 because she started with $350 then she lost $200, so that would be $150 now, then she lost $23, which she is now at 127 dollars, then she returned her book for $35 and now has 162 dollars, then she loses $15 dollars and is left with $147.

4. Separate 77 into two parts so that one part is 4 less than twice as much as the other. Find each part.

Igoryamba

Answer:

50,27

Step-by-step explanation:

let the parts be x and y

x+y=77

x=2y-4

substitute

2y-4+y=77

3y=77+4

3y=81

y=81/3=27

x=2×27-4=54-4=50

The least squares regression line is y=0.6831x+11.25

Step-by-step explanation:

LSRL is the the Least Squares Regression Line.The formula for regression line is y=mx+b where m is the slope of the line and b is the y-intercept value of the line.

First find the slope, m of the line from the means and standard deviations given

x has a mean of 17.2 g and a standard deviation of 14.0 g

y has a mean of 23.5 g and a standard deviation of 16.4 g

The correlation coefficient in both cases is 0.83, hence the slope m is given by;

m=r(Sy/Sx) where m is the slope of the line, Sy is standard deviation of y values, Sx is standard deviation of x values and r is the correction coefficient.

m= 0.5 * 23.5/17.2 =0.6831

Find the value of b, the y-intercept

b=Y-mX where X and Y are the mean values for x and y respectively

b=23.5-0.6831*17.2

b=23.5-11.75=11.25

The LSRL is y=0.6831x+11.25
