Answer:
C
Step-by-step explanation:
A constant correlation is essentially when the points on a scatter plot do not show any type of pattern or correlation; the points are literally scattered rather randomly, which would cause the graph to neither increase nor decrease.
Meanwhile, a positive correlation means that the points on the plot follow a line with a positive slope. In other words, it increases to the right.
Thus, the answer is C.
Hope this helps!
Answer: a) 
b) 25165824000
Step-by-step explanation:
The exponential equation for growth is given by :-
, where a= initial value , b =multiplicative growth factor and t = time.
Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.
i.e. a = 1500 and b= 2
Then, the function N that models the number of bacteria after t hours will be :
To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get
Hence, the number of bacteria after 24 hours is 25165824000.
Answer:
x=20°
Step-by-step explanation:
x° + 100° + 3x° = 180° => 4x°+100°=180° => 4x=180°-100°=80° => x=80° : 4 = 20° => x=20°
Answer:
8x+16 ft^2
Step-by-step explanation:
First we find the total area of the large rectangle
A = l*w
A = (x+3) * (x+5)
FOIL
A = x^2 +5x+3x+15
A = x^2 +8x+15
Now we find the area of the inner rectangle
A = lw
A = (x+1) (x-1)
FOIL
A = x^2 -x+x -1
A = x^2 -1
To find the shaded area, take the large rectangle and subtract the small rectangle
x^2 +8x+15 - (x^2 -1)
Distribute the minus sign
x^2 +8x+15 - x^2 +1
Combine like terms
8x+16
