Answer:
6720 ways different
Step-by-step explanation:
In this case, we must calculate the different ways using the permutation formula:
nPr = n! / (n - r)!
where n is the total number of people and r would come being the group of person that you want to put together the groups, therefore n = 8 and r = 5
replacing:
8P5 = 8! / (8 - 5)!
8P5 = 6720
That is to say that there are 6720 ways different winning groups are possible
Answer:
Step-by-step explanation:
Slope-intercept form is
where m is the slope
A. The slope is 8/5, and the -1/2 means that the point (0, -1/2) falls on the line, therefore the slope-intercept form is y+1/2=8/5(x-0) or y+1/2=8/5x
B. The slope is -5/8, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=-5/8(x-0) or y+1/2=-5/8x
C. The slope is 5/8, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=5/8(x-0) or y-1/2=5/8x
D. The slope is 8/5, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=8/5(x-0) or y-1/2=8/5x
8 people because there are 5 people plus Jonas(1) plus his 2 friends so 5+1+2=8
Answer:
It seems there's more information in you question that you haven't posted.
7 months = 7 * (365/12) = 213 days
The half-life of chromium 51 is 27.7 days.
After 7 months, chromium 51 will have undergone 7.69 half-lives.
To solve for the ending amount we'll use the formula:
Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives
We'll say the beginning amount =1
Ending Amount = 1 / 2^7.69
Ending Amount = 0.0048426082
Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.
