Let x be a random variable representing the mean thickness of alutin.
a.) P(2.97 < x < 3.08) = P((2.97 - 3.05)/0.025 < z < (3.08 - 3.05)/0.025) = P(-3.2 < z < 1.2) = P(z < 1.2) - P(z < -3.2) = P(z < 1.2) - [1 - P(z < 3.2)] = P(z < 1.2) + P(z < 3.2) - 1 = 0.88493 + 0.99931 - 1 = 0.88424
Answer:
Option C. 32/3
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form 
or 
we know that
For p=14, x=16
Find the value of k
substitute the values
so
The equation is equal to
Find the value of p when x=21
substitute the value of x in the equation
simplify
Divide by 7 both numerator and denominator
Answer:
a = g/c - r/c + d/c
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
1st change 1 5/6 into a mixed number:
1 5/6 = 11/6
New problem:
8/10 divided by 11/6
to divide fractions you turn the 1st fraction upside down and then change the division sign to a multiplication sign:
8/10 / 11/6
10/8 * 11/6
=55/24 or 1 7/24
No it is not because it is 47,000
