Answer:
1/15
Step-by-step explanation:
Given that:
Total Number of M&M's = (4 + 1 + 3 + 2) = 10
Number of yellow M&M's = 3
Probability = required outcome / Total possible outcomes
First pick (choosing without replacement)
P(choosing a yellow M&M) = 3 / 10
Second pick :
P(choosing a yellow M&M) = 2 / 9
P(choosing 2 yellow M&M) = 3/10 * 2/9 = 6/90 = 1/15
what is the distance between (-6-4) and (-5,-4)
Step-by-step explanation:
take as if this points are on a line segment AB
Dab = square root of ( xa - xb) ^2 + ( y a- yb) ^2
= square root of [ (-6) - (-5) ]^2 + [ (-4) - (-4) ]^2
= square root of (-1)^2 + (0)^2
= square root of 1 + 0
= square root of 1
= 1 units
The distance from AB is 1 unit

Find the indicated side of the
triangle.

[?]
a
Enter
Answer:
a = [tex]\frac{12}{\sqrt{3} }[/tex]
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{12}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
a × [tex]\sqrt{3}[/tex] = 12 ( divide both sides by [tex]\sqrt{3}[/tex] )
a = [tex]\frac{12}{\sqrt{3} }[/tex]

Answer:
[tex]\frac{x-1}{x+2}[/tex]
Step-by-step explanation:
simplifying the equation: [tex]x^2-3x+2/x^2-1[/tex]
1) Rewrite the equation so it's easier to understand:
[tex]\frac{x^2-3x+2}{x^2-4}[/tex]
2) factor [tex]x^2-3x+2[/tex]:
[tex]x^2-3x+2[/tex] [tex]=> (x-1)(x-2)[/tex]
3) factor [tex]x^2-4[/tex]:
[tex]x^2-4 => (x+2)(x-2)[/tex]
Meaning: [tex]\frac{(x-1)(x-2)}{(x+2)(x-2)}[/tex]
4) Cancel the common factor: [tex](x-2)[/tex] from the numerator and the denominator:
[tex]=\frac{x-1}{x+2}[/tex]
Write the equation for each graph.

how do I get the answer to 2/5 times 3
Answer:
6/5
Step-by-step explanation:
2/5*3=2/5*3/1=6/5
Answer:
[tex]\frac{6}{5}[/tex] or [tex]1\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\frac{2}{5} *3[/tex]
3 can be rewritten as 3/1
[tex]=\frac{2}{5}*\frac{3}{1}[/tex]
Multiply the numerators and denominators
[tex]2*3=6\\5*1=5[/tex]
[tex]= \frac{6}{5}[/tex]
You can also change this into a mixed number by dividing the numerator by the denominator and writing the remainder as the numerator:
[tex]= 1\frac{1}{5}[/tex]
I hope this helps!

7a.C
7b.Angle AED
7c.Angle 8
7d. Angle 6 and 8
Step-by-step explanation:
6a. The labeled angles are vertical angles so we set them equal to each other.
[tex]7x - 8 = 6x + 11[/tex]
[tex]7x = 6x + 19[/tex]
[tex]x = 19[/tex]
7a.Angle 11 is near Point C so Point C is the vertex.
7b. Angle 5 vertex is E so we can use any 3 points as an angle as long as E is in the middle example, and the angles are on the left side so we can use
[tex]aed[/tex]
Write the angle sign as well.
7c. Angle 6 is vertical from Angle 8.
7d. Angle 7 and 6 form a linear pair and since Angle 6=Angle 8, Angle 7 and 8 form a linear pair as well.
What is the meaning of the point with an x-coordinate of 2?
Answer:
A
Step-by-step explanation:
Because the x-coordinate is in seconds. Which eliminates answer B
Also, the Y-coordinate is measured in 40 meters per unit, this eliminates C and D.
Allen wants to have a mean of 90 on his math quizzes. So far, he has scored 86, 94, 88, 95, and 89. What is the least score that Allen needs on his next quiz to have a mean of 90?
Answer:
88
Step-by-step explanation:
[tex] \frac{86 + 94 + 88 + 95 + 89 + x}{6} = 90[/tex]
The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.
Solve for x:
[tex]86 + 94 + 88 + 95 + 89 + x = 540[/tex]
[tex]452 + x = 540[/tex]
[tex]x = 88[/tex]
Thus, Allen needs at least an 88 to obtain a mean of at least 90.

Mr. Jennings is shopping for a car loan. He wants to buy a car that costs $18,000. He plans to pay $5,000 in cash and get a loan for the rest. If the annual interest rate on the loan is 5%, how much interest will he pay in the first year?
Answer:
$650
Step-by-step explanation:
Interest = amount of the loan x interest rate x time
Amount of the loan = price of the car - cash payment
$18,000 - $5,000 = $13,000
interest rate = 5%
time = 1 year
$13,000 x 0.05 x 1 = $650
