Plot the intercepts:

y=-1

x=?

to find the x intercept, you dont solve the equation as it is solved in the slope-intercept form. instead, you simply plug in 0 for y:

0=1/4x-4

0=1/4x-4+4

4=1/4x

4/1/4=1/4x

1/4=0.25

x=16

revise:

y=(0, -1)

x=(16,0)

graph the slope for y=-1/2x-1: start from say point (0,-1)

graph the slope for y=1/4x-4: start from say point (16,0) ; you can just ise the intercept (0,-4) since the graph is diluted small...anyways

the points intersect at (4, -3) so thats the solution to the equations

NOTE: when graphing slopes that are negative either the numerator or the denominator can be graphed negative. so I graphed the first equation with the numerator as the positive and the denominator as the negative : rise= 1 ; run: -2. once i got to the end of the provided graph i started from the -1 y-intercept again and graphed the equation using: rise=-1; run=2

*graphing messes me up, too*

You invest $850 into a stock market fund, which grows at a rate of approximately 4% each year. Write an equation that can be use

SCORPION-xisa [38]

We have been given that you invest $850 into a stock market fund, which grows at a rate of approximately 4% each year. We are asked to write an equation that can be used to calculate the amount of money in the fund after x years.

We will use exponential growth formula to solve our given problem.

An exponential function is in form $y=a\cdot (1+r)^x$ , where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

Let us convert 4% into decimal.

$4\%=\frac{4}{100}=0.04$ .

We have $a=840$ and $r=0.04$ , so our equation would be:

$y=850\cdot (1+0.04)^x$

$y=850\cdot (1.04)^x$

Therefore, the equation $y=850\cdot (1.04)^x$ can be used to calculate the amount of money in the fund after x years.

Unoccupied seats on flights cause airlines to lose revenue. Suppose a large airline wants to estimate its mean number of unoccup

Mkey [24]

The given sample's 95% confidence interval is 11.6 ± 0.5357. I.e., from the lower bound 11.06 to the upper bound 12.14. Its margin error is 0.5357.

<h3>How to find the confidence interval?</h3>

To find the confidence interval C.I,

Determine the mean(μ) of the sample
Determine the standard deviation(σ)
Determine the z-score for the given confidence level using the z-score table
Using all these, the confidence interval is calculated by the formula, C. I = μ ± z(σ/√n) where n is the sample size and z(σ/√n) gives the margin error. So, we can also write C. I = mean ± margin error.

<h3>Calculation:</h3>

It is given that,

Sample size n = 225

Sample mean μ = 11.6

Standard deviation σ = 4.1

Since 95% confidence interval, z-score is 1.96

So, the required confidence interval is calculated by,

C. I = μ ± z(σ/√n) or mean ± margin error

On substituting,

C. I = 11.6 ± 1.96(4.1/√225)

= 11.6 ± 1.96 × 0.2733

= 11.6 ± 0.5357

So, the lower bound = 11.6 - 0.5357 = 11.065 and

the upper bound = 11.6 + 0.5357 = 12.135.

Thus, the confidence interval is from 11.06 to 12.14, and its margin error is 0.0537 for the population mean number of unoccupied seats per flight.
