Answer: 100,000,000

Step-by-step explanation:

We know that the census method is a complete enumeration survey method where each and every person in the given population is selected for the data collection.

If a population consists of 100,000,000 people and a census is taken, then all the 100,000,000 are sampled .

Hence, the number of people sampled = 100,000,000

What is the equasion of the line that passes through (0,5) and (2,3)
Annette [7]

The equation for a line is mx + b = y where m is the slope and b is the y intercept. To find the slope, we need to use the equation m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}.


m = \frac{5 - 3}{0 - 2}


m = \frac{2}{-2}


m = -1


Therefore, m is equal to -1. Normally, we would then have to plug in m and one of the points to find b. However, because the point (0,5) is the y-intercept (the y-intercept is the point on the line where x is equal to 0), we can skip this step and go straight to forming the final equation, which is y=-1x+5.

The product of two consecutive numbers exceeds the square
Lyrx [107]

Answer:

20,21

Step-by-step explanation:

Let x be the first number.

Let y be the 2nd number.

Given y - x = 1 (since they are consecutive)

Rearrange it: y = x+1 (equation 1)

Also given:

xy-20=x^{2} (equation 2)

Now we can substitute y = x + 1 into equation 2.

x(x+1)-20 = x^{2} \\x^{2} +x-20 = x^{2} \\x-20=x^{2} -x^{2} \\x-20=0\\x=20

Since we know x, the smaller number is 20, we can substitute to equation 1 to find y, the larger number.

y = 20+1

= 21.

Therefore the 2 numbers are 20 and 21.
