Answer:
75 M
Step-by-step explanation:
4350/58=75
So if they'll hire 40% women, and they're hiring 10 people, this means that they'll hire 4 women. And the rest of the people are all men, or 6 of them.
So basically, you can think of this like a tree, taking the men's side first, with 15 possible hires in the beginning, and then 14 more stemming off of that, and then 13 more stemming of those, etc.
So basically it would be:
15 * 14 * 13 * 12 * 11 * 10
Because there are four spots for men, and there were 15 men, and after every hire, there will be one less applicant, because there would've been one hire instead.
So;
15 * 14 * 13 * 12 * 11 * 10 = 3603600
And then women just do the same thing.
10 * 9 * 8 * 7 = 5040
Then just multiply those together as well.
18162144000 is your final answer.
Let the third angle be x.
Sum of the interior angles of a triangle = 180°
42 + 84 + x = 180
126 + x = 180
x = 180 - 126
x = 54°
Hence, the third angle is 54°.
Answer:
a = 3, b = - 7
Step-by-step explanation:
Substitute x = 2 into the equation and equate to 5, that is
a(2)² + b = 5
4a + b = 5 → (1)
Substitute x = 3 into the equation and equate to 20
a(3)² + b = 20
9a + b = 20 → (2)
Subtract (1) from (2) term by term to eliminate b
(9a - 4a) + (b - b) = (20 - 5), that is
5a = 15 ( divide both sides by 5 )
a = 3
Substitute a = 3 into either of the 2 equations and solve for b
Substituting in (1)
4(3) + b = 5
12 + b = 5 ( subtract 12 from both sides )
b = - 7
