The slope of the line is 6, meaning that you can eliminate A,C. Since the point slope formula is y-y1=m(x-x1) you just need to see if the points are correct.

B. (3,9)
D. (1,-3)

While these do contain one point, substitute the coordinates to see which contain both.

B.

(1,-3): -3-9=6(1-3): -12=-12
(3,9): 9-9=6(9-3): 0= 6(6)

D.

(1,-3): -3+3=6(1-1): 0=6(0); 0=0
(3,9): 9+3=6(3-1): 12=6(2): 12=12

D is correct since the coordinate are on the line.

The function LaTeX: f\left(x\right)=2\cdot5^xf ( x ) = 2 ⋅ 5 x can be used to represent an exponential growth curve. Which of th
masha68 [24]

Answer:

(2,20)

Step-by-step explanation:

The given function is

f(x) = 2 \cdot \:  {5}^{x}

To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;

For the first point we substitute x=3 and f(x)=250

250= 2 \cdot \:  {5}^{3}  \:  \\ 250 = 2 \times 125 \\ 250 = 250

This is true.

For the second point (2,20), we put x=2 and y=20 to get:

20= 2 \cdot \:  {5}^{2}  \\ 20 = 2 \times 25 \\ 20 = 50

This is false, hence (2,20) does not lie on this curve.

For (1,10), we have:

10= 2 \cdot \:  {5}^{1}  \\ 10 = 10

This is also true

Finally for (2,50), we have;

50= 2 \cdot \:  {5}^{2}  \\ 50 = 2 \times 25 \\ 50 = 50

This is also true.

What is a probability ?
docker41 [41]

Answer:

A number that measures the likelihood that the event will occur.

Step-by-step explanation:

Probability is a measure of the frequency of occurrence of a phenomenon, the value of which can be expressed qualitatively or quantitatively. Probability is quantified as a real number between 0 and 1, although sometimes probability is also expressed as a percentage. The probability is 0 when the event cannot or will never happen, and the probability is 1 when it happens for sure or it always happens. If the probability is between these values, the event is not common and its occurrence is uncertain. The higher the probability value, the more common the event is or the more certain it will occur.
