Hello!

Step-by-step explanation:

Slope formula: $\frac{Y^2-Y^1}{X^2-X^1}=\frac{rise}{run}$

$\frac{(-1)-(-1)=-1+1=0}{(-3)-6=-9}=\frac{0}{-9}=\frac{0/0}{-9/0}=0$

<u><em>Answer is 0.</em></u>

<u><em>There are no slope it should be undefined.</em></u>

Hope this helps!

Tito bought a rare album for $68.00 and later sold it for $76.00. What is the percent of increase, rounded to the nearest tenth?

gogolik [260]

70-80=10
hope this help the
68 rounded to the nearest tenth equals 70
and 76 rounded to the nearest tenth equals 80
so if you subtract 80-70=10 Tito increased the percent up to 10 dollars

What is the equation of the following line? Be sure to scroll down first to see

Rom4ik [11]

<h2>Answer:</h2>

-1/3x

<h2>Step-by-step explanation:</h2><h3>Known :</h3>

x1 = -3
x2 = 0
y1 = 1
y2 = 0

<h3>Asked :</h3>

Correct line equation

<h3>Solution :</h3>

We can find the straight line equation using this formula,

$\frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1}$

Insert all we know inside the formula,

$\frac{y-1}{0-1} = \frac{x-(-3)}{0-(-3)}\\\frac{y-1}{-1} = \frac{x +3}{3}\\$

Use cross multiplication,

3(y - 1) = -1(x + 3)\

3y - 3 = -x - 3

3y = -x - 3 + 3

3y = -x

y = -1/3x

<h3>Conclusion :</h3>

The correct equation is y = -1/3x

Help me to solve this problem

anyanavicka [17]

Here,

Volume of cylinder = 539^3 cm

Circumference = 22 cm

Height = ?

Now,

Circumference = 2πr

or, 22 = 2*22/7*r

or, 22 = 44/7*r

or, 154/44 = r

◆ r = 3.5 cm

Then,

Volume of cylinder = πr^2h

or, 539 = 22/7*(3.5)^2*h

or, 539 = 22/7*12.25*h

or, 539 = 269.5/7*h

or, 3773 = 269.5*h

or, 3773/269.5 = h

◆ h = 14 cm

I hope it's help you...

I hope you understand...

Thanks♥♥

The mean weight of frozen yogurt cups in an ice cream parlor is 8 oz.Suppose the weight of each cup served is normally distribut

vaieri [72.5K]

Answer:

10.03% probability of getting a cup weighing more than 8.64oz

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 8, \sigma = 0.5$

What is the probability of getting a cup weighing more than 8.64oz

This is the 1 subtracted by the pvalue of Z when X = 8.64. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{8.64 - 8}{0.5}$

$Z = 1.28$

$Z = 1.28$ has a pvalue of 0.8997

1 - 0.8997 = 0.1003

10.03% probability of getting a cup weighing more than 8.64oz
