Answer:
235
Step-by-step explanation:
The population equation is given as P= 2.726x + 126.189
-To find the number of years since 1980, we subtract the start year from the current year(2020):
X=2020-1980=40
We substitute the x value in the population equation to find the current population:
P=2.76x+126.189 but x=40
P=2.76(40)+126.189=235.229
Rounding off then the population in the current year is 235
This is true. The closer to the mean that a value is, the more likely it is to occur.
In this case, two and three standard deviations away are both fairly unlikely, however, two is still more likely to occur than three.
Where are the two questions ?
Answer:
C
Step-by-step explanation:
4x + 3 = x + 3x + 5
4x + 3 = 4x + 5 //-4x on both sides
3 = 5 //Since the statement is false, it's no solution.
If, it had 3 = 3 or any number n = n, the solution would be infinite. But, if x is equal to any number n, x=n, it would have only one solution.
