Answer:
Probability is 0.3506
Step-by-step explanation:
We are given
mean is 8mm
so, 
standard deviation is 2.2 mm
so, 
x-varies from 7mm to 9mm
At x=7:
we can use formula
we can plug values
At x=9:
we can use formula
we can plug values
So, z is between -0.45455 and 0.45455
now, we can use normal distribution table
and we get
Probability is 0.3506

Answer:
x = 2 and y = 1
Step-by-step explanation:
First, solve for y by substituting the second equation as x into the first equation
-2x - 3y = -7
-2(y + 1) - 3y = -7
Simplify and solve for y
-2y - 2 - 3y = -7
-5y - 2 = -7
-5y = -5
y = 1
Solve for x by plugging in 1 into the second equation
y + 1 = x
1 + 1 = x
2 = x
So, the answer is x = 2 and y = 1
