A bag contains:
• 5 red marbles
• 6 blue marbles
• 3 green marbles
• 4 black marbles
• 2 yellow marbles
A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?
Answer:
35/100
Step-by-step explanation:
P(green or black) = 3/20 + 4/20 = 7/20
7/20 = 35/100
Answer:
35 times
Step-by-step explanation:
all of them added together is 20 7/20 7x5=35 because 20 goes into 100 5 times

If y ∝ [tex]\frac{1}{x}[/tex] and y = 4 when x = 2.5, find :
(a) y when x = 20
(b) x when y = 5
Answer:
Step-by-step explanation:
Y = k1/x
4 = k 1/2.5
2.5 x 4 = k
10 = k
Now using this equation we will find the other answers
A) find y when x = 20
Y = k 1/x
Putting values
= 10(1/20) = 1/2 = 0.5
B) find x when y = 5
Y = k 1/x
Putting values
5 = 10 1/x
5x = 10
x = 10/5 = 2

Answer:
c.29
Step-by-step explanation:
Your equation is 3x+18+75=180
Then, you combine like numbers so 75+18 so your equation is now 3x+93=180
Next, you subtract the 93 and get 3x=87
Finally, divide 87 by 3 to get x=29!!
Hope this helps have a great day :)

In trapezoid MNPQ shown below, MN QP,. 108 m M. ∠ = ,. 4 15 m P x. ∠ = - , and. 3 21 m Q x. ∠ = + . Explain why m N. ∠ must be 127
Answer:
The answer is below
Step-by-step explanation:
A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base. Also, the angles on the same leg of a trapezoid (adjacent angles) are supplementary (add up to 180°).
In trapezoid MNPQ:
∠M + ∠Q = 180° (angles on the same leg are supplementary)
108 + (3x + 21) = 180
3x + 129 = 180
3x = 51
x = 17
Also:
∠N + ∠P = 180° (angles on the same leg are supplementary)
∠N + (4x - 15) = 180
∠N = 180 - (4x - 15)
∠N = 180 - 4x + 15
∠N = 195 - 4x
substitute x = 17°:
∠N = 195 - 4(17)
∠N = 127°

Alan bought a package of 6 socks for $8.99. Brittney bought a package of 12 socks for $16.25. which was the better buy? explain
Answer:
12 socks for $16.25.
Step-by-step explanation:
divide 8.99 by 6 you get 1.49.

Answer:
D) About 40 miles
Step-by-step explanation:
Using the Pythagorean theorem, you caculate c=√ a^2 + b^2
Oceanfront to Landview is 5(5) units = 25
Landview to Seaside is 6(5) units = 30
25^2 = 625
30^2 = 900
√625 + 900 = 39.0512....
Basically it’s 40 miles
Answer:
The answer is D, about 40 miles.
Step-by-step explanation:
Use the pythagorean theorem.
Distance between Seaside & Landview: 6
Distance between Landview & Oceanfront: 5
6^2 times 5^2 = [tex]\sqrt{61}[/tex]
[tex]\sqrt{61}[/tex] times 5 = 39.05124838
39.05124838 ≈ 40

Help im behind my math class. pls
Answer:
Please check the explanation.
Step-by-step explanation:
From the given diagram, we can observe that r and s are the two parallel lines intersected by the two transversal lines.
Therefore, the pairs of alternating interior angles formed by the two transversal lines are:
∠1 & ∠5 ∠2 & ∠4∠2 & ∠7 ∠3 & ∠6We know that alternating interior angles formed by a transversal line are congruent.
Thus,
∠1 = ∠5 ∠2 = ∠4∠2 = ∠7 ∠3 = ∠6Part a)
Given
m∠1 = 3x + 42
m∠5 = 8x - 8
As
∠1 = ∠5
So
3x + 42 = 8x - 8
flipe the equation
8x - 8 = 3x + 42
subtract 3x from both sides
8x - 8 - 3x = 3x + 42 - 3x
5x - 8 = 42
add 8 to both sides
5x - 8 + 8 = 42 + 8
5x = 50
divide both sides by 5
5x/5 = 50/5
x = 10.0000 (Rounded to four decimal places)
Thus, the value of x = 10.0000 (Rounded to four decimal places)
Part b)
Given
m∠6 = 12°
It is clear that angles ∠6 and angle ∠7 lie on a straight line.
Thus,
The sum of ∠6 and ∠7 is 180°.
∠6 + ∠7 = 180°
substituting m ∠ 6 = 12° in ∠6 + ∠7 = 180°
12° + ∠7 = 180°
subtract 12 from both sides
12° + ∠7 - 12° = 180° - 12°
∠7 = 168°
Thus, measure of angle ∠7 = 168°.
We already know that alternating interior angles formed by a transversal line are congruent.
∠7 and ∠2 are alternating interior angles.
Thus,
∠2 = ∠7
As ∠7 = 168°.
Therefore,
∠2 = 168°
Hence, we conclude that
∠2 = 168°

Answer:
3
Step-by-step explanation:
The f^-1 notation indicates you need to find the inverse of the function
y=2x+1
x=2y+1
Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x
7=2y+1
-2y=1-7
-2y=-6
Divide both side of the equation by -2
negative divide negative is positive so
y=3

Which function describes this table of values? х у 10 8 5 4 0 0 -5 -4 y = 2 y= y = x - 2 y=-3
Answer:
y=4/5x
Step-by-step explanation:
If you multiply the x value of 10, substitute it into the equation. Using the equation y=4/5x, you will get the y value of 8.
When you substitute the x value of 5 into the equation. You will get 4.
You do this for the rest of the x values and will get the correct y values.
