A rectangular parking lot has a perimeter of 310 meters. The length is 5 meters more than 4 times the width. What’s is the lengt
max2010maxim [7]

Answer:

w=30  l=125

Step-by-step explanation:

Perimeter =2l+2w

p=310

w =width

4w+5 = length(4 times plus 5 the width)

2(4w+5) + 2w = 310

8w+10 = 2w =310

10w=300

w=30    

30*4=120    120+5=125    l=125

2(125)+ 2(30)=  250+60 =310

Population mean = 80
alexira [117]

Answer:

The answer is : 0.0597

Step-by-step explanation:

Population mean = μ = 80

Standard deviation = σ = 20

Sample = N = 60

σ_mean = σ/√N

= (20)/√(60) = 2.582

Now we will find z1 and z2.

z1 = {(84) - μ}/σ_mean = {(84)-(80)}/(2.582)= 1.549

z2 = {(88) - μ}/σ_mean = {(88)-(80)}/(2.582)= 3.098

Now probability that the sample mean will be between 84 and 88 is given by:

Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597
