Answer:
79400000
Step-by-step explanation:
(6x10 5) = 600000
(8x10 7) = 80000000
80000000 - 600000 = 79400000
Answer:
a. yˆ=38,000+2500x
d. yˆ=38,000−1500x
Step-by-step explanation:
The least squares regression line for the population change of a small country has the following format:
![y^{^} = a + bx](https://tex.z-dn.net/?f=y%5E%7B%5E%7D%20%3D%20a%20%2B%20bx)
In which a is the initial population and b is the number of habitants for which the population increases/decreases a year.
Let's see each case
a. yˆ=38,000+2500x
The population starts at 38000 and increases by 2500 a year. This is a feasible assumption.
b. yˆ=38,000−3500x
The population starts at 38000 and increases by 3500 a year. By the year 2015, the population will be negative. This is not a feasible assumption.
c. yˆ=−38,000+2500x
The population cannot start at a negative value. So this is not a feasible assumption.
d. yˆ=38,000−1500x
The population starts at 38000 and decreases by 1500 a year. This is a feasible assumption.
c^2 = a^2 + b^2
looking for C the hypotenuse
a = 35
b = 12
These are the sides
c^2 = 35^2 + 12^2
c^2 = 1225 + 144
c^2 = 1369
Then take the square root of both sides to get C
C = 37
Answer:
2 cups of flour
Step-by-step explanation:
To make 5 batches of cookies, 10 cups of flour are required.
To make 1 batch of cookies:
10 cups ÷ 5 cups = 2 cups of flour.
