Answer:

y= -2x+9

Step-by-step explanation:

The equation will be written this way :

y= m*x+c

m is the slope
c is a constant
m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
y = -2x+c
replace x and y by the coordinates of a point to get c
1= -2*4+c
c = 9

y = -2x+9

Answer:

y=-9/4.5+9

Step-by-step explanation:

To find the equation you do y=mx+b which means y= slope + y-intercept.

To get the slop you do rise over run which in this situation is 9/4.5. And the y-intercept is when the line touches the y-axis and in this problem it is 9. So the answer is y=-9/4.5+9

The tables below show two functions. For each set of data:

slamgirl [31]

The first table, representing f(x), is linear. The data have a constant rate of change or slope:
(between the first two points): m = (y₂ - y₁)/(x₂ - x₁) = (22-18)/(-1--2) = 4/(-1+2) = 4/1 = 4. The rate of change between any two points is the same:
(between the last two points): m = (34-30)/(2-1) = 4/1 = 4.

The second table, representing g(x), is exponential. The data points are multiplied by the same constant between successive points. 2*2 = 4; 4*2= 8; 8*2 = 16, etc.

Answer:

$P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)$

And we can find the individual probabilities like this:

$P(X=8)=(10C8)(0.65)^0 (1-0.65)^{10-8}=0.176$

$P(X=9)=(10C9)(0.65)^1 (1-0.65)^{10-9}=0.072$

$P(X=10)=(10C10)(0.65)^2 (1-0.65)^{10-10}=0.013$

And adding we got:

$P(X \geq 8)= P(X=8) +P(X=9) +P(X=10)= 0.176+0.072+0.013=0.262$

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=10, p=0.65)$
