For this case, the first thing we must do is define a variable.
We have then:
t: number of years
P (t): number of people since 2010
We know that:
1) There were 30,700 people in the city
2) The population is growing at a rate of 850 people per year.
The equation modeling the problem is given by:
Answer:
a formula for the city's population is:
Answer:
This condition is true.
Step-by-step explanation:
A sample of 2,845 auto workers was selected to learn if they would go on strike.
Over 50% of those in the sample declared they would strike.
We can assume that the majority of all auto workers favor a strike. This is true because, in the sample, it is declared that 50% of workers would strike.
And this sample represents the whole majority or population. Hence we can say that a majority of all auto workers favor a strike.
Answer: Ratio of black horses to all horses = 59/62
Step-by-step explanation:
Total number of horses = 62
Total number of white horses = 3
Assuming that the rest horses are black. That means the total number of black horses would be 62-3 =59. So there are 59 black horses and there are 3 white horses.
Ratio of black horses to all horses will be the total number of black horses / the total number of horses.
Ratio of black horses to all horses
= 59/62 or 59:62
It can also be expressed in decimals which will become
0.952
Answer:
Step-by-step explanation:
The square of 2, -2 is 4. square of 3, -3 is 9. so square root of 7 has to be less than 3 but more than 2. therefore the integers are either 2 and 3 or -3 and -2.
