During a certain year newspaper’s film critics reviewed a new movie every week, rating them from 0 to 4 stars. She awarded 4 stars to only 6 movies that year the rest of her rating are summarized in accompanying frequency. Find her mean and median rating for year.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
