Use a geometric model to factor 2x2 - x - 1 by following these steps:
Step 1: Model the polynomial by placing tiles in the
Product section.
Step 2: Drag one zero-pair tile to the product area. Then
use the tiles in the product area to form a
rectangle.
Step 3: Drag tiles to the sections labeled Factor 1 and
Factor 2 to represent the factors.

ONLY NEED STEP 3 plz

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb. the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
