we have that
between beats 2 and 3----------> (392-261.6)=130.4-------> increases
between beats 3 and 4----------> (392-392)=0-----> <span>it stays with the same value
</span>between beats 4 and 5----------> (444-392)=52--------> increases
between beats 5 and 6----------> (444-444)=0-----> it stays with the same value
between beats 6 and 7----------> (392-444)=-52-------> decreases

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group

kari74 [83]

Given:

The parent function is

$f(x)=8x+9$

To find:

The function after the reflection over the x-axis.

Solution:

We know that, if a function f(x) reflected over x-axis to get the function g(x), then

$g(x)=-f(x)$

Putting $f(x)=8x+9$ , we get

$g(x)=-(8x+9)$

$g(x)=-8x-9$

The function after the reflection over the x-axis is $g(x)=-8x-9$ .

Therefore, the correct option is B.

Is 800 cm bigger than 8 m

Soloha48 [4]

Convert 8m to cm.

1 m = 100 cm

Multiply:

8 * 100 = 800

So 8 m is equal to 800 cm.

Both of them are equal, so 800 cm is not bigger than 8 m.

A random sample of 20 purchases showed the sample mean of $48.77 and the sample standard deviation s is $17.58. How large is the

laila [671]

Answer:

<h2>$5.03</h2>

Step-by-step explanation:

Given data

Sample Mean (M): $48.77

Sample Size (n): 20

Standard Deviation (σ) : $17.58

Confidence Level: 80%

we know that z*-Values for 80% Confidence Levels is 1.28

the expression for margin of error is given bellow\

MOE= z*σ/√n

We can now substitute into the expression and solve for the MOE as

MOE= 1.28*17.58/√20

MOE= 22.502/4.47

MOE= 22.502/4.47

MOE= 5.03

The margin of error for a 80 % confidence interval is $5.03
