Ataxi driver makes $24.50 in an hour, but uses $6.75 worth of gas during that time. what will the driver's total earnings for the hour be, after paying for gas? $16.25 $17.75 $21.50 $19.25 $15.50

Solve for x and y a x= 13.3 y= 16.7 b x= 23.3 y= 12.5 c x= 7.5 y= 16.7 d x=7.5 y= 12.5

Y=x+2 4x+3y= -36 system of equation

Summary statistics given for independent simple random samples from two populations. use the pooled t-interval procedure to obtain specified confidence interval. x1=71.6, s1=3.9, n1=11, x2=67.9, s2=3.4, n2=9 determine a 99% confidence level.
