Answer:

Number of ways of selecting two students is 15

Step-by-step explanation:

number of ways of selecting n out of r  is given by

n_{C_{r} } =\frac{n!}{r!(n-r)!}

It is given that there are 6 seniors on student council.

2 students are selected for district meeting

So we have  n= 6 and r=2

number of ways of selecting two students =6_{C_{2} }

                                                                       =\frac{6!}{2!(6-2)!}

                                                                       =\frac{6!}{2!4!}=15

So we have number of ways of selecting two students is 15

Triangle X Y Z is shown. Angle X Z Y is 90 degrees and angle X Y Z is 41 degrees. The length of Z X is 22.
skad [1K]

The equation that could be used to solve for the length of XY is XY = 22/sin(41)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Sine rule is used to show the relationship between the sides and angles of a trinagles.

Using sine rule on triangle XYZ:

XY / sin(Z) = XZ / sin(Y)

XY / sin(90) = 22/sin(41)

XY = 22/sin(41)

The equation that could be used to solve for the length of XY is XY = 22/sin(41)
