Total marbles: 7 + 7 + 7 + 7 = 28

There is a total of 28 marbles. 7 are blue.

The probability is the number of blue/ total marbles = 7/28 which reduces to 1/4

The probability is 1/4

Answer:

have a good day/night may i please have a branllist

Step-by-step explanation:

1/3

There is 21 marbles and if you divided by 3 it gets 7.

7/21 is equal to 1/3

Therefore the possibility of picking a blue marble is 1/3.

there are an equal amount of all three colors of marbles in the bag, so the probability of selecting a blue marble is just 1/3.

Answer:

b║f

c║e

Step-by-step explanation:

Given a diagram,

Lines b, c, d, e, f and a transversal line 'a'.

Here line 'b' makes an angle with line 'a' is 89.5° and line 'f' makes an angle with line 'a' is also 89.5° (180°-90.5° = 89.5°)

Since corresponding angles are same.

So, line 'b' is parallel to line 'f'.

And line 'c' makes an angle with line 'a' is 91.5° and line 'e' makes an angle with line 'a' is also 91.5° (180°-88.5° = 91.5°)

Since corresponding angles are same.

So, line 'c' is parallel to line 'e'.

Therefore,

b║f

c║e

That's the final answer.

Given the two points (-1,-4) and (2,5): a. Find the slope between these two points
Dvinal [7]
Easy, using \frac{y1-y2}{x1-x2} to find the intercept:

\frac{-4-5}{-1-2}=

\frac{-9}{-3}=3

This is your slope. m=3

To find y=mx+b form

-4=3(-1)+b

-4=-3+b

-1=b

What is the solution to (x+6)(x+2)=60
Citrus2011 [14]
Distribute to eliminate the parenthesis

x^2 + 2x + 6x + 12 = 60

Combine like terms

x^2 + 8x + 12 = 60

Subtract 60 from both sides

x^2 + 8x - 48 = 0

Factor the equation

(x+12)(x-4)=0
x+12=0
x+4=0

x= -12 and -4

Gustavo and yuki were asked to find an explicit formula for the sequence 19, 0, -19, -38...
KiRa [710]

Answer:

<h2>Neither Gustavo nor Yuki</h2>

Step-by-step explanation:

It's an arithmetic sequence.

0-19=-19\\-19-0=-19\\-38-(-19)=-38+19=-19

The difference is constant.

The explicit formula of an arithmetic sequence:

a_n=a_1+(n-1)d

Substitute:

a_1=19,\ d=-19

a_n=19+(n-1)(-19)             <em>use distributive property</em>

a_n=19-19n+19\\\\a_n=(19+19)-19n\\\\a_n=38-19n
