Answer:

1/3

Step-by-step explanation:

\left[\begin{array}{cccc}Bought\ Lunch&Boys&Girls&Total\\0\ up\ to\ 10&10&5&15\\10\ up\ to\ 20&20&25&45\\Total&30&30&60\end{array}\right]

The number of boys who bought 10 to 20 lunches is 20.

The total number of students is 60.

So the probability is 20/60 = 1/3.

A system of equations is graphed on the coordinate plane. y=−6x−3y=−x+2 What is the solution to the system of equations? Enter t
Mamont248 [21]
If you equate both, the y is eliminated:

-6x-3 = -x+2

Simplify this to find x:

-5x = 5
x = -1

Fill in x=-1 in either equation:

y = --1 + 2 = 3

So (-1,3) is the solution, it is where the lines intercept.

Suppose cos(O) = 12/13, Quadrant I. Find sin(O).<br> A:13/12<br> B:5/13<br> C:13/5<br> D:5/12
noname [10]

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13

Hope this helps
