49 students are selected at random from sophomore class 39 from the junior class and 48 from senior class what type of sampling is used simple random ,stratified , systematic ,convenience

(B)Stratified

Step-by-step explanation:

Stratified sampling refers to a sampling method in which the entire population is first divided into groups/strata before a random sample is taken from each strata.

The school population in this case has been divided into these strata,

From these classes, a random sample of 49,39 and 48 students respectively was then taken,

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .
