The decay factor for the annual rate of change of - 55 % is 0.45.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = - 55 % = - 55 / 100 = - 0.55

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (- 0.55)

B = 1 - 0.55

B = 0.45

Now, the value of B is less than 1 therefore, the corresponding decay factor is 0.45.

How to determine relationship between two variables with standard deviation?
luda_lava [24]
Standard deviation is the average distance between two points on the graph. If the standard deviation (sd) is high, then the variables relationship is more spread out and unlike one another. The smaller the sd, the closer and less varied the variables are.

The weights of a certain dog breed are approximately normally distributed with a mean of μ = 55 pounds, and a standard deviation
weqwewe [10]

Answer:

(a)z=-1

(b)48.5 pounds

(c)61.5 pounds

Step-by-step explanation:

z-score=\dfrac{x-\mu}{\sigma}

Given:

Mean, μ = 55 pounds

Standard deviation,σ = 6 pounds.

(a)For a dog that weighs 49 pounds.

x=49 pounds

The z-score

=\dfrac{49-55}{6}\\=\dfrac{-6}{6}\\\\=-1

(b)When a dog has a z-score of -1.09

-1.09=\dfrac{x-55}{6}\\x-55=-6.54\\x=55-6.54\\x=48.46 \approx 48.5$ pounds (to the nearest tenth)

The weight of a dog with a z-score of -1.09 is 48.5 pounds.

(c)When a dog has a z-score of 1.09

1.09=\dfrac{x-55}{6}\\x-55=6.54\\x=55+6.54\\x=61.54 \approx 61.5$ pounds (to the nearest tenth)

The weight of a dog with a z-score of 1.09 is 61.5 pounds.

What is the equation in standard form of the line shown on the graph
dybincka [34]

Answer:

Step-by-step explanation:

We take two points (0,-3) and (4,0)

eq. of line thro' two points is y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)=(0+3)/(4-0)=3/4

Reqd. eq . is y-(-3)=3/4(x-0)

or y=3/4(x)-3
