A line is parallel to y = 5x + 3 and

WARRIOR [948]

Answer:

y = 5x - 6

Step-by-step explanation:

1. In a linear equation, it is represented by y = mx + b

2. A line parallel to another has the same slope (m) but a different y-intercept (b)

3. So we know that it is y = 5x as the first half. However, we need to find the new y-intercept.

4. Let's plug in the point we know into the equation, and see what amount we are missing (the y-intercept)

5. y = 5(3)

6. y = 15, however, we know that y = 9. That's a difference of -6.

This shows us that the y-intercept is -6 making the full equation:

y = 5x - 6

We can check by putting the point back into the equation:

y = 5(3) - 6

y = 15 - 6

y = 9

This correlates with the original point, we have solved the equation.

${d}^{2} \div (4c) - b + 5a \\ = {(8)}^{2} \div( 4 \times 2) - 3 + 5 \times \frac{1}{5} \\ = 64 \div 8 - 3 + 1 \\ = 8 - 3 + 1 \\ = 9- 3 \\ = 6$

Your firm wants to investigate how much money the typical tourist will spend on their next visit to New York? How many tourists

dimaraw [331]

Answer:

$n=(\frac{2.58(59)}{20})^2 =57.93$

And if we round up the answer we see that the value of n to ensure the margin of error required $\pm=20$ $ is n=58.

C) 58

Step-by-step explanation:

Assuming this :"Your firm wants to investigate how much money the typical tourist will spend on their next visit to New York. How many tourists should be included in your sample if you want to be 99% confident that the sample mean is within $20 from the population mean? From previous studies, we know that the standard deviation is $59."

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Assuming the X follows a normal distribution

$X \sim N(\mu, \sigma=59)$
