To find the slope of the line, you need two points.
(-2 , 5) and (3 , -5)
5 - (-5) / -2 - 3
10 / -5 = -2
The slope of the line is -2. So your answer is C.
Answer:
The population in 2003 was 234 million
Step-by-step explanation:
In order to calculate the population in 2003 we would have to use the The exponential growth formula as follows:
p(y)=ir^t
According to the given data:
p(y)=233 million
i=231 million
t
=1999-1991
Therefore, 233 million=231 million r^(1999-1991)
(233 million/231 million)^(1/8)=r
p(y)=231 million(233 million/231 million)^((y-1991)/8)
Therefore, in 2003
p(2003)=231 million(233 million/231 million)^((2003-1991)/8)
p(2003)=231 million(233 million/231 million)^(1.5)
p(2003)=234 million
The population in 2003 was 234 million
If the value in the parentheses is > 1 then its exponential growth otherwise its exponential delay.
for example the first one is growth ( because of the 1.25)
second one is decay ( because of the 1/2)
Answer:
range = 90
mean = 317.14
Step-by-step explanation:
range = higest - lowest value = 365 - 275 = 90
mean is avarage of all = sum of all/ 7 = 317.14
Answer:
5:3
Step-by-step explanation:
So, ratio of girls to boys is 20:12 . You can reduce this ratio, the same way you reduce a fraction. Both numbers have a common fact of 4 , so divide both by 4 . In simplest form, this ratio is 5:3 .
