There are Horseback Riding Lessons. Last year, the 8 kids in a beginner's horseback-riding group were 7, 9, and 10 years old. The mode of the ages was 10, and the mean was 9. There were equal numbers of 7-year-olds and 9-year-olds. This year the group has stayed together. How many are there of 11 years old?

i want to die

what the hell man, i just want the points lol

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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.

answer: the answer is e
