Answer:
1 / 16
Step-by-step explanation:
Divide each term by 2.
2 / 2 = 1
32 / 2 = 16.
1 / 16 = 2 / 32
Answer:
I would say c. you welcome for my so called help
Answer:
Between 38 and 86 months.
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by
.
In this question:
Mean of 62, standard deviation of 12.
Between what two lifetimes does Chebyshev's Theorem guarantee that we will find at least approximately 75% of the computers?
Within 2 standard deviations of the mean, so:
62 - 2*12 = 38
62 + 2*12 = 86
Between 38 and 86 months.
L = 10a + a
L = 11 a
W = 1/10 (11a)
W = 1.1 a
Perimeter = 2(L + W)
Perimeter = 2*(11a + 1.1a)
Perimeter = 22a + 2.2 a
Perimeter = 24.2 a
Area = L * W
Area = 11a * 1.1a
Area = 12.1 a^2
The perimeter is 2*area
P = 2*A
P = 2* 12.1 a^2
P = 24.2 a^2
Now put in the perimeter on the left side of the above equation.
24.2a = 24.2 a^2 Divide both sides by 24.2
1 a = a^2 Divide by a
1 = a
The length = 11*a = 11*1 = 11
The Width = 1.1 a = 1.1 * 1 = 1.1
