Answer:

Both students are correct because polynomials can be grouped in different ways to factor. Both ways result in a common binomial factor between the groups. Using the distributive property , this common binomial term can be factored out. Each grouping results in the same two binomial factors.

Step-by-step explanation:

Solve.

7x-5x-3=x+4

Calculate like terms.

7x-5x=2x

Rearrange.

2x-3=x+4

Apply inverse addition.

2x-3+3=x+4+3

2x=x+7

Isolate 2x by subtraction.

2x-x=x-x+7

the manager of a grocery store has taken a random sample of 100 customers the average length of time it took these 100 customers

lora16 [44]

Answer:

with a .95 probability, the sample mean will provide a margin of error 0.196

Step-by-step explanation:

margin of error (ME) from the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in the .95 confidence level (1.96)

s is the population standard deviation (1 min.)

N is the sample size (100)

ME= $\frac{1.96*1}{\sqrt{100} }$ =0.196

95% confidence interval for check-out time would be 3 ±0.196 min
