Answer:
Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.
Step-by-step explanation:
Chebyshev's Theorem states that, in a sample:
75% of the measures are within 2 standard deviations of the mean
89% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 58
Standard deviation = 4
Between what two heights does Chebyshev's Theorem guarantee that we will find at least approximately 89 % of the choir members?
Within 3 standard deviations the mean, so from 3 standard deviations below the mean to 3 standard deviations above the mean.
3 standard deviations below the mean
58 - 3*4 = 46
3 standard deviations above the mean
58 + 3*4 = 70
Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.
Answer:
n=−43/3
Step-by-step explanation:
−42/3=2n/3+1/3+n/3
−14=2/3n+1/3+1/3n
−14=(2/3n+1/3n)+(1/3)
−14=n+1/3
Flip the equation.
n+1/3=−14
Subtract 1/3 from both sides.
n+1/3−1/3=−14−1/3
n=−43/3
Shop #1 has the best price for 21 pizzas because it is $105, while Shop #2 costs $147 for 21 pizzas which is a lot more money. they would save $42, which is 147-105=42. hope this helps:)
Answer:
-864
Step-by-step explanation:
The determinant of a matrix product is the product of the determinants. The determinant of a transpose is the same as the determinant of the original. Hence ...
The multiplication of an n×n matrix by a scalar 'a' multiplies its determinant by a^n, so the desired determinant is ...
