In an experiment to test tensile strengths of I=5 different types of copper wire, J=4 samples were taken from each. the mean square for errors were computed to be MSTr=2573.3 and MSE= 1394.2 , respectively. use the F test at level .05 to test H0 : |u1 ... = |u5 versus Ha:at least two of the |ui's are unequal

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

to complete this square you have to rotate about the origin 270 degrees clockwise.
