Answer:

95 students

Step-by-step explanation:

25 students -- 19 have sibling

1 student -- (19/25)

125 students -- (19/25) * 125 = 95

Therefore, 95 students out of 125 are expected to have at least one sibling.

Thenks and mark me brainliest :))

Answer:

95

Step-by-step explanation:

Calculate the experimental probability of choosing a student who has at least one sibling:  It is 19/25, or 0.56.

If 125 students are selected, this probability applies.  Multiply 125 by 0.56:

0.56(125 students) = 95

95 students could be expected to report having at least one sibling.

Given: triangle ABC,
Andrei [34K]

The value of AD in triangle ABC is approximately 9 cm.

BC = 6cm

Using trigonometric ratio for triangle CBD

sin 60° = opposite / hypotenuse

0.86602540378  =  DC / 6

cross multiply

DC = 6 × 0.86602540378

DC = 5.19615242271

DC = 5.20 cm

Let's find side AD as follows:

tan 60° = AD / adjacent

AD = 5.20 × tan 60°

AD = 9.00666419936

AD ≈ 9 cm

You need to use the angle sum of  a triangle in triangle CAD to express y in term of x
for triangla CAD , y = (180 -x) /2
180 = 3x + [ (180-x)/2]

x = 36

hope this helps
