The number of permutations of objects from objects is .
The number of ways of choosing 3 digits from 6 digits without replacement ( order is important) is . This is the number of all possible permutations of choosing 3 from 6.
Correct choice is 120.
Answer:
The correct way to interpret the difference of a number divided by 6 and 5 equals 8 is
n/6 - 5 = 8. I believe that another tutor has misled you; there should be only one division, applying to n only.
Answer:
y = 6x-4
Step-by-step explanation:
3x - 1/2 y =2
We need to solve for y to get the equation in slope intercept form
Subtract 3x from each side
3x-3x - 1/2 y =-3x+2
-1/2 y = -3x+2
Multiply each side by -2
-2*-1/2 y = -2*(-3x+2)
y = -2*(-3x+2)
Distribute
y = 6x-4
The slope is 6 and the y intercept (where it crosses the y axis) is -4
You would go down the y axis 5 boxes
Answer:
<em>36%</em>
Step-by-step explanation:
"8 kg of mixed nuts containing 26% peanuts"
weight of peanuts: 26% * 8 kg = 0.26 * 8 kg = 2.08 kg
"5 kg ... that contain 52% peanuts"
weight of peanuts: 52% * 5 kg = 0.52 * 5 kg = 2.6 kg
Total weight of peanuts: 2.08 kg + 2.6 kg = 4.68 kg
Total weight of mixed nuts: 8 kg + 5 kg
percent of peanuts: (4.68 kg)/(13 kg) * 100% = 36%
