There is 16 ounces in 1 pound. so you would want to divide 12.40 by 5 = $2.48 . so its $2.48 for a pound divide by 2 and you answer would be $1.24... i hope that helps
Answer:
A) 8x - 4 || B) 6x + 29
Step-by-step explanation:
A) -2x + 5 + 10x - 9
→ -2x+10x+5-9
→ -2x+10x-4
→ 8x - 4
B) 3(x + 7) + 2(-x + 4) + 5x
→ 3x + 21 - 2x + 8 + 5x
→ 6x + 29
Solution: We are given:
μ=3.1,σ=0.5,n=50
We have to find P(Mean <2.9)
We need to first find the z score
z= (xbar-μ)/(σ/sqrt(n))
=(2.9-3.1)/(0.5/sqrt(50))
=(-0.2)/0.0707
=-2.83
Now we have to find P(z<-2.83)
Using the standard normal table, we have:
P(z<-2.83)=0.0023
Therefore the probability of the sample mean being less the 2.9 inches is 0.0023
