How many different groups of 6 shirts can be formed from 10 shirts for a display

2 answers:

6 0

I believe the shirts are different (in color, in size, in style,...), is so then:

¹⁰C₆ = (10! )/( 6! )( 10-6) ! = 210 COMBBINATIONS

Is 2(x+6)+8= 2x+20??

Angelina_Jolie [31]

Yes this is correct. if you do distribution and multiply 2 times x it's 2x. you then multiply 2 times 6 and this equals 12. add twelve and 8 and this equals 20. the answer 2x+20 is correct

If sin theta=-1/4 and theta terminates in the third quadrant, find the exact value of sin2 theta.

DIA [1.3K]

Answer:

$sin(2\theta)=\frac{\sqrt{15}}{8}$

Step-by-step explanation:

We are given

$sin(\theta)=-\frac{1}{4}$

Firstly, we can draw triangle

angle lies in third quadrant

so, we get

$cos(\theta)=-\frac{\sqrt{15} }{4}$

now, we can use formula

$sin(2\theta)=2sin(\theta)\times cos(\theta)$

now, we can plug values

$sin(2\theta)=2\times -\frac{1}{4}\times -\frac{\sqrt{15} }{4}$

now, we can simplify it

and we get

$sin(2\theta)=\frac{\sqrt{15}}{8}$
