Answer:
P(t) = - 60t + 4720
3580
Step-by-step explanation:
Given :
m = (y2 - y1)/(x2 - x1)
m = (4250 - 4600) / (8 - 2)
m = - 360 / 6
m = - 60
Using the point slope relation :
y - y1 = m(x - x1)
y - 4600 = - 60(x - 2)
y - 4600 = - 60x + 120
y - 4600 + 4600 = - 60x + 120 + 4600
y = - 60x + 4720
P(t) = - 60t + 4720
To predict population in 2009 :
2009 - 1990 = 19 years
Put t = 19
P(19) = - 60(19) + 4720
P(19) = - 1140 + 4720
P(19) = 3580
Answer:
Step-by-step explanation:
Mode definition is the number which appears most often in a set of numbers. Since the mode is the same amount of bubbles it is not A.
The range of a set of data is the difference between the highest and lowest values in the set.
To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
The data has already been ordered for you so you take the highest number and subtract the smallest number.
Cityview Zoo 44-37=7
Countryside Zoo 45-38=7
8(x - 6) = 4x
Distribute.
8x - 48 = 4x
Subtract 8x from both sides.
8x -8x - 48 =4x -8x
Now you have...
-48 = -4x
Divide -4 by both sides.
-48/-4 = -4x/-4
12 = x
The number is 12.
