Which normal distribution has a wider​ spread: the one with mean 9 and standard deviation 5 or the one with mean 5 and standard

deviation 9​?

The spread is controlled by the standard deviation. The mean value only controls where the center of the bell is.


So a normal distribution with a sigma of 9 is wider than one with a sigma of 5.

What is the multiplicative rate of change for the exponential function f(x) = f start bracket x end bracket equals two start bra
jeka94

Answer:

The multiplicative rate of change is \dfrac{2}{5}.

Step-by-step explanation:

You are given the function

f(x)=2\cdot \left(\dfrac{5}{2}\right)^{-x}

First, use the following property of exponents

\left(\dfrac{a}{b}\right)^{-x}=\left(\dfrac{b}{a}\right)^{x}

So, your function is

f(x)=2\cdot \left(\dfrac{2}{5}\right)^{x}

If the exponential function is written in the form

f(x)=a\cdot b^x,

then b is the multiplicative rate of change for this exponential function.

In your case, the multiplicative rate of change is \dfrac{2}{5}.

How do i find each product by factoring the tens? 3x2, 3x20, and 3x200
RUDIKE [14]
Well, since it only asking about the product, you don't have to multiply the result 
The product would be :
3 x 2 = 6
3x 20 =  3 x 2 x 10  = 60
3 x 200 = 3 x 2 x 10 x 10 = 600

hope this helps

What is another way to group the factors (3x2)x5
tia_tia [17]

<u>Answer</u>

3×(2×5)

<u>Explanation</u>

Multiplication of numbers is associative. For example,

(a×b)×c = a×(b×c)

This is also called grouping. We multiply more than 2 numbers by grouping.

For the equation given above, (3x2)x5, it can also be grouped as 3×(2×5).
