Compute the permutation.

1 answer:

8 0

So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula $^{a} P_{c}$ where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = $^{8} P_{3}$
= 336

 O R

By using the formula $Permutation = \frac{a ! }{( a - c) !}$ where a is the number of available digits and c is the number of digits to be selected.

⇒ $Permutation = \frac{8 ! }{( 8 - 3) !}$

⇒ $Permutation = \frac{40, 320 }{120}$

⇒ Permutation = 336

ii. yes. suppose a is negative, so write a = -b where b is positive. let c be a

positive number such that c" = b. then (-c)" = a because (-1)" = -1 since

Answer: Prokhorova is more outstanding.

Step-by-step explanation: To compare scores from different distributions, first standardize it:

z-score = $\frac{x-\mu}{\sigma}$

where

x is the individual mean you want to compare

μ is the mean of the population

σ is standard deviation

For Gertrud Bacher:

z-score = $\frac{129-137}{5}$

z-score = $-1.6$ (s)

The negative sign indicates Bacher's mean is less than the mean

For Yelena Prokhorova:

z-score = $\frac{660-600}{30}$

z-score = 2 (cm)

The positive sign indicates Prokhorova's mean is more than the mean.

Using z-score table, you determine the percentiles are:

For Bacher: Percentile = 5.5%

For Prokhorova: Percentile = 97.7%

Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.

SHORT ANSWER

Gradient of the line formed;
m= $\frac{change in y}{change in x}$
m= $\frac{-2-1}{6--5}$
m= $\frac{-3}{11}$
y=mx+c
y= $\frac{-3}{11} x+c$
Replacing for x and y;
1=-3/11*(-5)+c
1=15/11+c
c=1-15/11
c=-4/11
y= $\frac{-3}{11} x- \frac{4}{11}$
