SHOW YOUR WORK 4.) On the Module 8 test, 60 of Mrs. Alcock's students earned B’s.
Before she finishes grading them, she wants to predict how many
students will earn B's on the Module 9 math test. Mrs. Alcock generates
a random sample using the first 20 tests she grades to determine how
many students earned B's(80%-89%).

you are only given the cost not the amount of pounds.

probably the last option

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(
