Formula for probability: [tex]\boxed{\displaystyle Probability = \frac{number\ of\ possible\ outcomes}{total\ number\ of \ outcomes} }[/tex]Solution:Total number of marbles = 5 + 8 + 2 = 15
Number of red marbles = 5
Probability to draw a red marble at the first trial = 5/15
Number of marbles left = 15 - 1 = 14
Number of Red marbles left = 5 - 1 = 4
Probability to draw a red marble at the second trial = 4/14
Total probability:[tex]\displaystyle =Probability \ of \ drawing \ a \ red \ marble \ at \ the \ (second \ attempt +first \ attempt)\\\\= \frac{5}{15} + \frac{4}{14} \\\\\rule[225]{225}{2}[/tex]

First we need to find the GCF of this polynomial; when we find it, we should factor it out, or divide all the terms by it.
Since the greatest common factor (GCF) of this polynomial is 3v, we divide both terms by 3v:-
3v(v+3)

Ash buys 5 bunches of flowers. Each bunch contains 10 flowers. He gets 8 more flowers from his yard.
Let f represent the number of flowers Ash has in all.
Answer:
Ash has 58 flowers in total
Step-by-step explanation:
Given:
- buys 5 bunches
- each bunch contains 10 flowers
- 8 more flowers from his yard.
5 bunches times 10 flowers plus the 8 more flowers from the garden
F = 10(5) + 8
F = 50 + 8
F = 58
Answer:
Ash has 58 flowers in all
Step-by-step explanation:
Y representing = bunches of flowers
F representing = the flower
1. Y=10f
2. Y=10f 5 x 10 = 50
3. Y=10f 50 + 8 = 58
4. Y=10f
5. Y-10f
f = 58

need help with my aleks
Answer:
Below in bold,
Step-by-step explanation:
The angles in a triangle add up to 180 degrees.
So the equation is:
7x + 8 + 4x + x + 4 = 180
12x + 12 = 180 <-------- Required equation
12x = 168
x = 14.
m< L = 14 + 4 = 18 degrees
m< M = 7(14) + 8 = 106 degrees

Two similar polygons have a scale factor of three. The smaller polygon has an area of 42 cm² and perimeter of 50 cm. what is the area of the larger polygon? and what is the perimeter of the larger polygon?
Step-by-step explanation:
a scale factor applies to every line, that means also to every side of the polygon.
the area of a polygon is always created out of the product (multiplication) of 2 dimensions (or sides).
while a perimeter is a pure sum of sides.
so the perimeter grows by the same factor as the sides : scale factor 3.
the perimeter of the larger polygon is therefore :
50 × 3 = 150 cm
and the area of the larger polygon ?
remember, that the area is always the product of 2 sides (or the sum of products of 2 sides).
and so, the scale factor enters these multiplications twice, and it gets therefore squared : 3×3 = 9.
so, the area of the larger polygon is then
42 × 9 = 378 cm²

Answer:
49.36 degrees to the nearest hundredth.
Step-by-step explanation:
In the right angled triangle formed the adjacent side is 25.88 m and the opposite = 30.15 m.
So tan B = 30.15 / 25.88 = 1.16499
So m < B = 49.36 degrees.

y₂ - y₁ / x₂ - x₁70 - 0 / 4 - 070/417.5Netflix is considering a new romcom (romantic comedy) series. Before making a final decision, the producers design an experiment to estimate the proportion of viewers who would watch the series. A random sample of 1,000 viewers was selected and asked to watch the first two episodes. After viewing the episodes, 625 viewers indicated they would watch the new series. (Use t Distribution Table & z Distribution Table.) (Round your answers to 3 decimal places.)
Required:
a. Estimate the value of the population proportion of people who would watch the new series.
b. Develop a 99% confidence interval for the population proportion of people who would watch the new series.
A) the value of the population proportion of people who would watch the new series is 5 out of 8 viewers, and B) a 99% confidence interval for the population proportion of people who would watch the new series indicates that between 61.87% and 63.13% of viewers will watch the new series.
ProportionsGiven that Netflix is considering a new romcom (romantic comedy) series, and a random sample of 1,000 viewers was selected and 625 viewers indicated they would watch the new series, for A) estimate the value of the population proportion of people who would watch the new series, and B) develop a 99% confidence interval for the population proportion of people who would watch the new series, the following calculations must be made:
A)
625 = 1
1000 = X
1000 / 625 = X
1.6 = X
10 out of 16, or 5 out of 8.
B)
62.5 x 0.99 = 61.875
62.5 x 1.01 = 63.125
Therefore, A) the value of the population proportion of people who would watch the new series is 5 out of 8 viewers, and B) a 99% confidence interval for the population proportion of people who would watch the new series indicates that between 61.87% and 63.13% of viewers will watch the new series.

Solve for the variable: 3(x+2) - 9 = 15 - 4(5x - 2)
[tex]\tt 3(x+2)-9=15-4(5x-2)[/tex]
To solve this equation, let's apply the distributive property:-
Multiple 3 by ( x+2)/ Subtract 9 from 6 = -3/ and then use the distributive property to multiply −4 by (5x-2) :-
[tex]\tt 3x - 3=15 - 20x+8[/tex]
Add 15 and 8 = 23
[tex]\tt 3x - 3=23 - 20x[/tex]
Now, add 20x to both sides:-

Determine all missing angles below.
Answer:
a = 60, b = 19, c = 101, d = 79, e = 50
Step-by-step explanation:
Relations that are helpful here are ...
vertical angles are congruentan exterior angle is equal to the sum of the opposite interior anglesthe sum of angles forming a straight angle is 180°the sum of angles in a triangle is 180°__
Using these relations, we can find the unknown measures.
a° = 60° . . . . . these are vertical angles
51° +b° +110° = 180° ⇒ b° = 180° -161° = 19° . . . . straight angle
a° +b° +c° = 180°
c° = 180° -60° -19° = 101° . . . . sum of angles in a triangle
d° = 180° -101° = 79° . . . . . straight angle
e° = c° -51° = 50° . . . . . c° is exterior to the triangle
Write the equation of the line that passes through the point
(1,−5) and with the slope of −3. Write the in slope-intercept form.
Answer:
y = -3x -2
Step-by-step explanation:
Hi there!!
We're given that a line has a slope of -3 and it contains the point (1, -5)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
As we are already given the slope, we can immediately plug it into the equation.
Replace m with -3 in y=mx+b.
y = -3x + b
Now we need to find b
As the equation passes through the point (1, -5), we can use its values to help solve for b.
Substitute 1 as x and -5 as y:
-5 = -3(1) + b
Multiply
-5 = -3 + b
Add 3 to both sides
-2 = b
Substitute -2 as b into the equation
y = -3x - 2
Hope this helps!
