Answer:
0.0090483
Approximately = 0.00905
Step-by-step explanation:
z = (x - μ)/σ, where
x is the raw score = 3.74
μ is the sample mean = population mean = 4 mm
σ is the sample standard deviation
This is calculated as:
= Population standard deviation/√n
Where n = number of samples = 100
σ = 1.1/√100
σ = 1.1/10 = 0.11
z = (3.74 - 4) / 0.11
z = -2.36364
Using the z score table to determine the probability,
The probability that the average thickness of the 100 sheets is less than 3.74 mm
P(x<3.74) = 0.0090483
Approximately = 0.00905
If I am understanding the question correctly a(-3, -3) and b(2, 3) Hope this helps!
The answer is -3

Answer:
No
Step-by-step explanation:750+200=950 +75=1025 +100=1125 +500=1625
X = 30
y = 120
30 x 4 = 120
120 + 120 = 240
240 + 120 = 360
