Without replacement, the probability that all three marbles drawn will be red is 0.01.
What is the probability?Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.
Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)
5/17 x 4/16 x 3/15 = 0.01
The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%
How to calculate probability?
We are given;
Number of red marbles = 5
Number of blue marbles = 8
Number of Green marbles = 4
Total number of marbles = 5 + 8 + 4
Total number of marbles = 17
Probability of first being red = 5/17
Probability of second being red = 4/16
Probability of third being red = 3/15
Thus;
P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)
P(all three marbles drawn are red) = 0.0147
Approximating to nearest tenth of a percent = 0.015 = 1.5%

Angle E and Angle F are Vertical Angles, If measure of Angle E is 3x + 33 and the measure of Angle F is 4x + 8, what is the value of x?
Answer:
Remember vertical angles are congruent so you can set these expression equal to each other and then solve the equation.
Angle F = angle E
4x + 8 = 3x + 33
Now solve for the x variable.

There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday. What percent of 8th graders did not try out for football?
Answer:
87.5%
Step-by-step explanation:
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.
The number is students not trying out for football last Thursday is calculated as:
376 students - 47 students
= 329 students
The percent of 8th graders that did not try out for football is calculated as:
329 students/376 students × 100
= 329/376 × 100
= 87.5 %

the first 4 terms and the 10th term for 3n+4
Answer:
first 4 terms =7,10,13,16
10th term = 34
Step-by-step explanation:
3n+4
3(1)+4=7
3(2)+4=10
3(3)+4=13
3(4)+4=16
7,10,13,16
10th term = 3(10)+4= 34
The first four terms of the sequence having nth term 3n+4, are 7, 10, 13, 16 and the 10th term is 34.
What is arithmetic sequence ?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.
Given that,
The nth term of a sequence is given by 3n+4,
To find the first 4 terms, substitute the values of n,
At n=1, the first term = 3(1) + 4 = 3 + 4 = 7
At n=2, the second term = 3(2)+4 = 6 + 4 = 10
At n=3, the third term = 3(3) + 4 = 9 + 4 = 13
At n=4, the fourth term = 3(4) + 4 = 12 + 4 = 16
For 10th term, substitute n=10.
At n=10, the tenth term = 3(10) + 4 = 30 + 4 = 34
The first four terms are 7, 10, 13, 16 and the 10th term is 34.

10x + 38

determine the value of x
Answer:
x= 2/3
Step-by-step explanation:
if they are equating,
10x +38 = 40+7x
10x-7x = 40-38
3x = 2
x= 2/3
Answer:
x = 0.6666666667
Step-by-step explanation:
Simplifying
10x + 38 = 40 + 7x
Reorder the terms:
38 + 10x = 40 + 7x
Solving
38 + 10x = 40 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
38 + 10x + -7x = 40 + 7x + -7x
Combine like terms: 10x + -7x = 3x
38 + 3x = 40 + 7x + -7x
Combine like terms: 7x + -7x = 0
38 + 3x = 40 + 0
38 + 3x = 40
Add '-38' to each side of the equation.
38 + -38 + 3x = 40 + -38
Combine like terms: 38 + -38 = 0
0 + 3x = 40 + -38
3x = 40 + -38
Combine like terms: 40 + -38 = 2
3x = 2
Divide each side by '3'.
x = 0.6666666667
Simplifying
x = 0.6666666667

Slope intercept
Answer:
the slope is 2/7 and the intercept is 4
Step-by-step explanation:
In order to find slope, you use the equation delta y over delta x which is the equation, y2-y1/x2-x1.
In this case you plug in each point and get the equation, 2-4/-7-0 or 4-2/0+7.
Simplify to get 2/7.
To find the intercept, you must see what's the y value when x is 0. In this case it's already given to you, so y intercept is 4.

By decomposing the design into two rectangular prisms, the surface area of the design is calculated as: A. 256 in.²
What is the Surface Area of a Rectangular Prism?The surface area of a rectangular prism is expressed as, S = 2(lw + lh + wh).
The design can be decomposed into top rectangular prism and bottom rectangular prism.
The surface area of the design = surface area of the top rectangular prism + surface area of the bottom rectangular prism - 2(area of the top rectangular prism that joins the bottom rectangular prism)
Surface area of the top rectangular prism = 2(lw + lh + wh) = 2(5×4 + 5×4 + 4×4) = 112 in.²
Surface area of the bottom rectangular prism = 2(lw + lh + wh) = 2(8×5 + 8×4 + 5×4) = 184 in.²
Area of the top rectangular prism that joins the bottom rectangular prism = l × w = 5 × 4 = 20 in.²
The surface area of the design = 112 + 184 - 2(20) = 256 in.²

Solve for y.
115°
108°
130°
90°
Answer:
115, A
Step-by-step explanation:
The formula to find the total interior angles is ([number of sides] - 2) x 180, so in this case it would be 540, and if you subtract all the other interior angles you wi ll get y! (90,135,112,and 88) (please excuse therandom spaces my spacebar isbroken)
The value of y from the figure is 115 degrees
PolygonsThe given polygon is a pentagon
The sum of an interior angle of the pentagon is 540 degrees
Taking the sum and equating to 540 will give:
90 + 135 + 112 + y + 88 = 540
y + 425 = 540
y = 540 - 425
y = 115 degres
Hence the value of y from the figure is 115 degrees

Answer:

2: 1.30
Step-by-step explanation:
Hope this helps
Answer:
0.80 and 1.30
Step-by-step explanation:
0.80, 1.05, 1.30, 1.55, 1.80, 2.05
... + 0.25 = 1.05
= 1.05 - 0.25
= 0.80
0.80 + 0.25 = 1.05
1.05 + 0.25 = 1.30
1.30 + 0.25 = 1.55
1.55 + 0.25 = 1.80
1.80 + 0.25 = 2.05
