PLEASE HELP ASAP it is my homework

0.4

Step-by-step explanation:

The number of ways to select 3 points out of 5 points:

N1 = 5C3 =  (5 x 4 x 3)/(1 x 2 x3) = 10

The number of ways to select 3 points out of 4 points that are already collinear:

N2 = 4C3 = (4 x 3 x 2)/(1 x 2 x 3) = 4

=> The probability of selecting 3 points that are collinear:

P = N2/N1 = 4/10 = 0.4

Good day, Harry!

send it over

step-by-step explanation:

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.
