Answer:

4 distinct zeroes

Step-by-step explanation:

You can not find the zeroes without the equation.

But here, they are asking for the no. of zeroes. Just count the no. of x-intercepts.. which is 4

There are 4 distinct zeroes.

Degree is 5 (odd).

0 is one of the zeroes with multiplicity 2

Other 3 zeroes have a multiplicity of 1

I'm assuming you're referring to problem 6. You are asked to find the number of x intercepts or roots, which is another term for "zero". I prefer the term root or x intercept as "zero" seems misleading. Anyways, all we do is count the number of times the graph crosses the x axis. This happens 4 times as shown in the attached image below. I have marked these points in red. The graph can directly cross over the x axis, or it can touch the x axis and then bounce back. Either way, it is considered an x intercept.

<h3>Answer: there are 4 x intercepts (or 4 roots)</h3>

Answer:

Step-by-step explanation:

a) The objective of the study is test the claim that the average gain in the green fees , lessons or equipment expenditure for participating golf facilities is less than $2,100 under the claim the null and alternative hypothesis are,

H₀ : μ = $2,100

H₀ : μ < $2,100

B) Suppose you selects α = 0.01

The probability that the null hypothesis is rejected when the average gain is $2,100 is 0.01

C) For α = 0.01

specify the rejection region of a large sample test

At the given level of significance 0.01 and the test is left-tailed then rejection level of a large-sample = < - 1.28

The graph shows the relationship between the amount of time that a backpacker hikes and the distance traveled.

julsineya [31]

Answer:

The points represent that <u>5 miles </u> were hiked in <u>3 hours.</u>

Step-by-step explanation:

So, lets go over what we need to know.

The x coordinates is the time.

The y coordinates is the miles.

We have (3, 5)

This is (x, y)

x = 3, and y = 5. Considering what we know above, the time is 3 hours, and the miles is 5.

To fill in the boxes, it asks "Blank miles are hiked in blank hours"

We know 5 miles are hiked in 3 hours.

So the fill in for the first part is 5, and the fill in for the second part is 3.

Hope this helps!

A movie streaming website charges an initial fee of $80, plus $4 for each movie that is streamed. How many movies must be stream

pochemuha

Answer:

80 movies must be streamed.

Step-by-step explanation:

To find the average cost, you must divide the total cost by the number of movies watched.

When you watch 1 movie, you pay the initial fee of $80 plus a $4 purchase of the film.

The equation is shown as such:

average cost = (total cost)/(number of movies)

Your total cost can be represented as $4x + 80$ , while the number of movies is represented as $x$ .

You want the average to equal 5, so your equation is shown as follows:

$5 = (4x+80)/x$

simplifying this, we get

$5 = 4 + \frac{80}{x}$

which can then be simplified to

$1 = \frac{80}{x}$

X = 80 movies.

(Round to the nearest tenth of a percent.) In 2011, the IRS increased the deductible mileage cost to

RUDIKE [14]

Answer:

$\%Change = 8.8\%$

Step-by-step explanation:

Given

$Initial = 51\ cents$

$Final = 55.5\ cents$

Required

Determine the percentage change

Percentage change is calculated as;

$\%Change = \frac{Final - Initial}{Initial} * 100\%$

$\%Change = \frac{55.5 - 51 }{51 } * 100\%$

$\%Change = \frac{4.5}{51} * 100\%$

$\%Change = \frac{4.5* 100\%}{51}$

$\%Change = \frac{450\%}{51}$

$\%Change = 8.8\%$

<em>Hence, the percentage change is approximately 8.8%</em>
