Answer:

1/6

Step-by-step explanation:

Simply just Add the different amounts of different crayons as your denominator, and find the number of red, as your numerator. This gets you 2/12. 2/12 = 1/6

Answer:

1/36

Step-by-step explanation:

We have 12 Crayons total

2 of those are red

So the chance of pulling one red is 2/12

If we have to find the chance of two thing happening (Getting two reds back to back) we have to multiply our chances. Think of how its harder to get the same thing twice in a row.

So its 2/12 × 2/12 = 4/144

Simplify and get 1/ 36

Ashley has 100 books that she wants to give away at the rate of n books per week. Write a recursive function that represents the
enyata [817]

Answer:

f(x) = f(x-1) - n  <--- this is the recursive formula

f(0) = 100

f(1) = f(0) - n = 100 - n

f(2) = f(1) - n = 100 - n - n = 100 - 2n

f(3) = f(2) - n = 100 - 2n - n = 100 - 3n

in general the EXPLICIT formula is f(x) = 100 - xn , x=0,1,2,3

Step-by-step explanation:

hope this helps if it is wrong let me know have a blessed day

Franklin measured and labeled the angles of a triangle as shown. Jennifer says that at least one of his measures is incorrect. E
ioda

Answer:

see the explanation

Step-by-step explanation:

First way

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

In this problem

37+97+134 > 180

therefore

At least one of Franklin's measures is incorrect

Second way

we know that

A triangle can only have at most one obtuse internal angle.

In this problem the triangle has two obtuse internal angles

Remember that an obtuse angle is an angle greater than 90 degrees

therefore

At least one of Franklin's measures is incorrect

Choose the equation that represents a line that passes through points (-1, 2) and (3, 1).
oksian1 [2.3K]

Answer:

<h2>B. x + 4y = 7</h2>

Step-by-step explanation:

\text{The point-slope form of an equation of a line:}\\\\y-y_1=m(x-x_1)\\\\m-slope\\\\\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\==============================

\text{We have the points (-1, 2) and (3, 1). Substitute:}\\\\m=\dfrac{1-2}{3-(-1)}=\dfrac{-1}{4}=-\dfrac{1}{4}\\\\\text{Put the value of a slope and the coordinates of the point (3, 1) }\\\text{to the equation of a line:}\\\\y-1=-\dfrac{1}{4}(x-3)\\\\\text{Convert to the standard form}\ Ax+By=C:\\\\y-1=-\dfrac{1}{4}(x-3)\qquad\text{multiply both sides by 4}\\\\4y-4=-(x-3)\\\\4y-4=-x-(-3)\qquad\text{add x to both sides}\\\\x+4y-4=3\qquad\text{add 4 to both sides}\\\\x+4y=7
