Samantha's notebook has 14 pages more than three times as much as Lisa's notebook.

1 answer:

4 0

First subtract the number of pages you have extra which is 14
260 - 14 =246
Next, because Samantha has 3x more pages you have to divide by 3
(doing opposite of what was done)
246/3 = 82
Final you get your answer of 82 pages in Lisa's notebook

If m(x)=x 5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Tatiana [17]

Answer:
m(x) has the same domain as (m*n)(x)

Explanation:
1- For m(x):
m(x) is a fraction. This means that the denominator cannot be zero, otherwise, the fraction would be undefined.
The denominator of m(x) would be zero at x = 1.
This means that the domain of m(x) can be any real number except 1

2- For n(x):
The value of x in n(x) can be any number. This is because there is no value that would make n(x) undefined.
This means that the domain of n(x) is all real numbers

3- For (m*n)(x):
(m*n)(x) = m(x) * n(x) = $\frac{x-5}{x-1} *(x-3) = \frac{(x-5)(x-3)}{(x-1)}$

We can note that the product is also a fraction. This means that the denominator cannot be zero.
The denominator here will be zero at x = 1.
This means that the domain of (m*n)(x) is all real numbers except 1.
This is the same as the domain of m(x)

Hope this helps :)

balandron [24]

The value of r indicates the negative correlation.

<h2>Given </h2>

Rikki decided to collect data to determine if a runner's time and speed are correlated.

She determined the data to have a correlation coefficient of -0. 5.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of the two variables.

She determined the data to have a correlation coefficient of -0. 5.

Here, the coefficient is negative which is -0.5.

This correlation coefficient indicates that there exists a weak negative correlation between the runner’s time and the speed.

This relation is negative because the correlation coefficient is negative.

Hence, The value of r indicates the negative correlation.

Answer:

49°

Step-by-step explanation:

First, solve for x.

3x-7+2x+17=90

5x+10=90

5x=80

x=16

Then put 16 in for x.

2(16)+17=
