<h3>
Answer: A) 6</h3>
=====================================================
Explanation:
Plug n = 6 and r = 5 into the nCr combination formula
Or you could use the shortcut
Yet another path you could take is to use Pascal's Triangle. Locate the row that starts with 1,6,... and then locate the second to last item. That value in the triangle is 6.
A real world interpretation is to consider having 6 people and you are selecting 5 of them to form a group where order doesn't matter. How many ways are there to do this? Well there are 6 such ways because there are 6 ways to leave someone out of the group.

Answer: A nut in botany is a simple dry fruit in which the ovary wall becomes increasingly hard as it matures, and where the seed remains unattached or free within the ovary wall. Most nuts come from the pistils with inferior ovaries (see flower) and all are indehiscent (not opening at maturity).
Step-by-step explanation:
To find a fraction of an amount you divide by the denominator and times by the numerator (divide by the bottom times by the top)
£1 divided by 10 is 10 pence
10 pence times 1 is 10 pence
£1 divided by 10 is 10 pence
10 pence times 3 is 30 pence
50 pence divided by 5 is 10 pence
10 pence times 1 is 10 pence
£1 divided by 2 is 50 pence
50 pence timed 1 is 50 pence
Answer:
4y+x-3=0
Step-by-step explanation:
The equation is y=mx+b
1) Use the coordinates from the first point
(-1,1)
1= -m+b
2) Use the coordinates frm the second point
(-5,2) (y=mx+b, use x=-5, y=2)
2=-5m+b
You have the system of equations
1=-m+b (multiply by -1) -1= m-b
2=-5m+b
Add the first equation (multiplied by -1) and the second one
-1+2= m-b-5m+b
1= -4m
m=-0.25
2=1.25+b
b=0.75
y=-0.25x+0.75
4y= -x+3
4y+x-3=0
