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.

mash [69]
This is the concept of algebra, given a polynomial with one variable like x and y, the degree is the largest exponent of the variable;
Given the expressions;
4x^3-2y^3+5y^2-5y The polynomial has a degree of 3 (both y and x have an exponent of 3)
3y3--xy=3y^3+xy The polynomial has a degree of 3 also (y has an exponent of 3)

aev [14]

Honestly, the most intelligent solution would be to light the candle first, since it has a longer duration and then I can light the lamp, and then I can light the newspaper. Then, I will use the newspaper to light the fire.

A bakery can make 60 donuts in 15 donutes. What is the unit rate at which the bakery makes donuts.
maria [59]

Answer:

4 donuts per minute/(donutes is that a typo?)

Step-by-step explanation:

if a bakery can make 60 donuts in 15 minutes, that is 60 donuts/15 minutes.

to reduce this fraction, the top and bottom can be divided by 15 to get 4 donuts/1 minute.
