Sin(12) ≈ 0.208

cos(x) = 0.208
  cos(x) = sin(12)
cos(78) = sin(12)

  cos(12) ≈ 0.978
  cos(68) ≈ 0.375
cos(102) ≈ -0.208
  cos(78) ≈ 0.208

The answer is D.

Answer:

Hence, the Female and not participated is $\frac{28}{100}=0.28\%$

Step-by-step explanation:

Let Total respondents $=100$

Participated in online action $(P)=65$

Men $(m)=45$ and Women $(F)=100-45=55$

Male and participated $(M\; \text{and}\;P)=38$

Female and participated $(F\; \text{and}\;P)=65-38=27$

Male and not participated is $45-38=7$

Female and not participated is $55-27=28$

Therefore, the Female and not participated is $\frac{28}{100}=0.28\%$

Hence, the correct option is $D$ .

Which expressions are factors of the expression<br><br> -24xyz - 12xy + 20xyz

Alex17521 [72]

Answer:

2xy

Step-by-step explanation:

A factor is a number of term you can factor out of each part of the expression/ or divide it by.

In -24xyz - 12xy + 20xyz

All three parts have xy, so it is a factor

All three don't have 12xz, because -12xy doesn't have z variable for instance.

All three have 2xy.

All three can't factor out 3y, because you can't divide 20 by 3 nicely.

All three can't factor out 4yz, because middle term -12xy doesn't have z.

All three can't factor out 12, because you can't nicely divide 20/12.

All three can factor out 4, because -24, -12, and 20 are all divisible by 4.
