Answer:
0.74 to 6.06
Step-by-step explanation:
The groups are independnet,
SE(xh bar-xa bar)=sqrt [sh^2/nh+sa^2/na]=sqrt [10.1^2/80+10.3^2/80]=1.61
At df=157, the t critical is 1.65
90%c.i=(xh bar-xa bar)+-tcritical SE(xh bar-xa bar)
=(25.2-21.8)+-1.65*1.61
=0.74 to 6.06
Answer:
V = 972m^3
Step-by-step explanation:
small = lwh = 9(2)(6)
large = lwh = 16(9)(6)
V = 9(2)(6) + 16(9)(6)
V = 108 + 864
V = 972m^3
Multiply the length and width for a rectangle like the one shown.
5.3(2.6) = 13.78 square yards.
6x + (-9) or 6x - 9
Try looking at the terms for the same things. Such as the variable like X and the negatives add together and make a negative
