From 1000 students half being boys and half being girls 100 names were pulled out of a hat to complete a survey for school what sampling method is being used?

The Random sampling method is being used.

Step-by-step explanation:

Consider the provided statement.

Random sample: If we select the subset of the individuals from the given set and the probability of getting selected for each individual is same, then it is known as the random sample.

There are 1000 students out of which 500 are boys and 500 are girls.

The probability of selecting a boy and a girl is the same.

If we pull out 100 names then the probability will be the same for the boys as well as for the girls.

Here, for each individual, the probability is the same.

Thus, the Random sampling method is being used.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
