Pls help I’ve been stuck on this. The height, in meters, of a machine piston can be modeled by the regression equation y=4.4sin(0.4x-1.7)+2.3 where x represents time, in seconds. To the nearest tenth of a meter, what is the height of the piston after 10 seconds?

which of the following sets of data would produce the largest value for an independent-measures t statistic? the two sample means are 10 and 20 with variances of 20 and 25 the two sample means are 10 and 20 with variances of 120 and 125 the two sample means are 10 and 12 with sample variances of 20 and 25 the two sample means are 10 and 12 with variances of 120 and 125

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20

Choose the more precise measurement. 26.4 cm or 8.39 cm
