Answer:

1/5

Step-by-step explanation:

Equation: \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

Points: (-3, -9) and (22, -4)

y_{2} is the second y point that shows up on the question, basically go by order. So it's -4

y_{1} is -9, because again, in order of which coordinates pop-up first in the question

x_{2} is 22, x_{1} is -3

Now input into the equation, to make it easier we'll split the fraction into 2 equations:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}} = y_{2} - y_{1} and x_{2} - x_{1}, we'll put them back in a fraction later

y_{2} - y_{1} = -4 - (-9) = -4 + 9 = 5

x_{2} - x_{1} = 22 - (-3) = 22 + 3 = 25

now put it in the fraction, remember y on top x on the bottom:

5/25, simplify, 1/5

Use the information in the figure. If F=116, find E<br><br> 58<br> 32<br> 116<br> 64
My name is Ann [436]

Step-by-step explanation:

Given that,

  • m∠F = 116°

We have to find the value of m∠E.

Here, two sides are equal, thus it is an isosceles triangle. As the two sides are equal, so their angles must be equal. So, ∠E and ∠D will be equal. Let us assume the measures of both ∠E and ∠D as x.

→ Sum of all the interior angles of ∆ = 180°

→ ∠E + ∠D + ∠F = 180°

→ 116° + x + x = 180°

→ 2x = 180° – 116°

→ 2x = 64°

→ x = 64° ÷ 2

→<u> x = 32°</u>

Henceforth,

→ m∠E = x

→ m∠E = 32°

You are randomly selecting 3 cans of regular and diet cola, but assume that there are 6 cans of regular cola and 7 cans of diet
gayaneshka [121]

Answer:0.367

Step-by-step explanation:

Given

There are 6 cans of regular and 7 cans of diet cola

number of ways of selecting 2 regular colas and 1 can of diet cola is

\Rightarrow ^6C_2\times ^7C_1

The total no of ways of selecting 3 items out of 13 items is

\Rightarrow ^{13}C_3

Probability is

\Rightarrow P=\dfrac{^6C_2\times ^7C_1}{^{13}C_3}=\dfrac{105}{286}\\\Rightarrow P=0.367
