2 which is the slope

if you use the pattern to get to 0 as the x value, you will get -3 as the y value meaning it is the y intercept so the answer is:

y=2x-3

PLEASE HELPPPPP!!!! (answer in decimal)
kakasveta [241]

Answer:

\approx 0.482659

Step-by-step explanation:

The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:

\frac{desired}{total}

However, the experimental probability can be described with the following formula:

\frac{number\ of\ desired\ outcomes}{number\ of \ trials}

The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:

\frac{tails}{total}

One can also rewrite the formula as the following. This is because the total is the sum of the number of the two outcomes:

\frac{tails}{heads+tails}

Substitute,

\frac{167}{167+179}

Simplify,

\frac{167}{346}

Rewrite as a decimal:

\approx 0.482659

Someone please help, its for a hw assignment I have due today. What is the equation of the line through (3, 7) that is perpendic
Brilliant_brown [7]

The required equation is:

y=-\frac{6}{5}x+\frac{53}{5}

Step-by-step explanation:

Let l_1 be the line through  (-1, -2) and (5, 3)

and l_2 be the line we require which passes through (3,7)

We have to find the lope of l_1 first

m_1=\frac{y_2-y_1}{x_2-x_1}\\=\frac{3-(-2)}{5-(-1)}\\=\frac{3+2}{5+1}\\=\frac{5}{6}

we have to find the equation of line perpendicular to l1

The product of slopes of two perpendicular lines is -1

Let m_2 be the slope of l_2

Then

\frac{5}{6}*m_2=-1\\m_2=-\frac{6}{5}

The general slope-intercept form is:

y=mx+b

Putting the value of slope

y=-\frac{6}{5}x+b

To find the value of b, we will put (3,7) in the equation

7=-\frac{6}{5}(3)+b\\7=-\frac{18}{5}+b\\b=7+\frac{18}{5}\\b=\frac{35+18}{5}\\b=\frac{53}{5}

Putting the values of b and m in standard slope intercept form:

y=-\frac{6}{5}x+\frac{53}{5}

Hence,

The required equation is:

y=-\frac{6}{5}x+\frac{53}{5}
