Slope intercept
y=mx+b
m=slope
b=yntercept
basically solve for y

-y+4x>-13
add y to both sides
4x>-13+y
flip and revers
y-13<4x
add 13 to both sides
y<4x+13

What is the shape graphed by the function r = 1+ sin theta

IRISSAK [1]

Answer: Is known as a "heart" shape.

Step-by-step explanation:

r = 1 + sin(θ)

Let's do it without a graph, let's use only math and logic:

remember that θ is measured from the x-axis

when θ = 0, we have r = 1 (so we have a radius of 1 over the x-axis)

when θ = pi/2, we have r = 1 + sin(pi/2) = 2

when θ = pi, we have r = 1 + sin(pi) = 1

when θ = 3*pi/2, we have r = 1 + sin(3*pi/2) = 0

First, we have symetry around the y-axis,

now, notice that the value of x in θ = 0, θ = pi and θ = 3*pi/2 is the same. so this is not a circle, this is actually a circle where the bottom part is flatted.

But not actually flat, because between θ = pi and θ = 2pi we are in the negative y-axis, so in this region we have two small bumps that connect in the point (0, 0)

This is a kinda "heart" shape.

mario walks his dog once every 8 days in the park, while todd walks his dog once every 14 days. today, both mario and todd walke

notsponge [240]

Assuming both Mario and Todd just walked today.

Mario is every 8 days

Todd is every 14 days.

The days that will coincide is the Least Common Multiple (LCM) of 8 and 14

2 / 8 14
2 / 4 7
2 /    2 7
7 /    1    7
    /    1 1

The LCM = 2 * 2* 2* 7 = 56

The will both walk together in the next 56 days.

Thank you in advance

4. The value f issue is the quantity of shares multiplied by the price of each share.

25,000 shares x $9.20 = $230,000.

The answer is b.$230,000

5. Total selling expense would be the commission plus all the fees.

Multiply the value of issue by the commission percentage and then add the other costs.

230,000 x 0.065 = 14,950

14,950 + 1,985 = $16,935

The answer is a. $16,935

6. Divide the total selling expense by the number of shares:

750,000 / 900,000 = 0.83

The answer is d. $0.83

a previous analysis of paper boxes showed that the standard deviation of the length is 9mm. What is the 98% confidence interval

il63 [147K]

We cannot calculate the confidence interval without the sample size. However, for the second question, the sample size needed would be 49.

The formula we use is

$n=(\frac{z_{\frac{\alpha}{2}}\times \sigma}{E})^2$

To find the z-score:
Convert 98% to a decimal: 0.98
Subtract from 1: 1-0.98 = 0.02
Divide by 2: 0.02/2 = 0.01
Subtract from 1: 1-0.01 = 0.99

Using a z-table (http://www.z-table.com) we see that this value is closest to a z-score of 2.33.

Using the z-score, our standard deviation (9) and our margin of error (3), we have:
$n=(\frac{2.33(9)}{3})^2=(6.99)^2=48.86\approx 49$
