a bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow. A marble is drawn at random. What is the probability that it is red? Make sure to reduce your answer. 25 points if you answer help pls :/
Answer:
40% chance
Step-by-step explanation:
4 marbles out of 10 are red. 4/10= 0.4= 40%
Answer: 2/5
Step-by-step explanation: If there're 10 marbles and 4 of them are red, then the probability of it being red is 4/10.
To reduce or simplify it, you must divide both 4 and 10 by 2, leaving you with 2/5.

The China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. If the list price is $58.75, what is the trade discount? What is the net price?
Answer: See explanation
Step-by-step explanation:
Since the complement is the difference between 100% and discount rate. Since the China Company offers a trade-discount rate that is 4 times the complement of the trade-discount rate. Therefore, the discount rate will be 80% and the complement 20%.
Therefore, the trade discount will be:
= List price × Trade discount rate
= $58.75 × 80%
= $58.75 × 0.8
= $47
Net price = List price - Trade discount
= $58.75 - $47
= $11.75

Step-by-step explanation:
The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.' a) What are the mean and standard deviation of the number of universal donors among the 6 people? b) What is the probability that there are exactly three universal donors?
Answer:
[tex]Mean = 0.36[/tex]
[tex]SD = 0.5817[/tex]
[tex]P(x=3) = 0.003588[/tex]
Step-by-step explanation:
Given
Let
A = Event of being a universal donor.
So:
[tex]P(A) = 0.06[/tex]
[tex]n = 6[/tex]
Solving (a): Mean and Standard deviation.
The mean is:
[tex]Mean = np[/tex]
[tex]Mean = 6 * 0.06[/tex]
[tex]Mean = 0.36[/tex]
The standard deviation is:
[tex]SD = \sqrt{np(1-p)}[/tex]
[tex]SD = \sqrt{6*0.06*(1-0.06)}[/tex]
[tex]SD = \sqrt{0.3384}[/tex]
[tex]SD = 0.5817[/tex]
Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:
[tex]P(x) = ^nC_x * p^x * (1-p)^{n-x}[/tex]
So, we have:
[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^{6-3}[/tex]
[tex]P(x=3) = ^6C_3 * 0.06^3 * (1-0.06)^3[/tex]
[tex]P(x=3) = 20 * 0.06^3 * (1-0.06)^3[/tex]
[tex]P(x=3) = 0.003588[/tex]

Find the sum of the parts of a given pizza.
1. 11/7. 2. 12/5
The sum of the parts 11/7 and 12/5 of pizza is 139/35.
It is given that the parts of pizza are:
[tex]1. 11/7\\2. 12/5\\[/tex]
It is required to find sum of the parts of pizza.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called denominator.
Calculating the sum of the parts of pizza:
[tex]=\frac{11}{7}+\frac{12}{5}[/tex]
[tex]=\frac{139}{35}[/tex]
Thus, the sum of the parts 11/7 and 12/5 of pizza is 139/35.

Step-by-step explanation:
Answer:
The answer is 4 cm
Step-by-step explanation:
Volume of the triangular prism = 544 m³
height of the prism (h) = 17 m
Also
Volume of the prism = Area of base * height
544 = Area of base * 17
Area of base = 544 / 17
Area of base = 32 m²
Now
Base of the triangle (b) = 16 m
Area of the triangle = 32 m³
height (h) = ?
We know
Area of triangle = 1/2 * b * h
32 = 1/2 * 16 * height
32 * 2 / 16 = height
height of the triangle = 4 m

29. Consider the equation:
3(1 + px) = 12x
For what value of p does the equation have no solution?
A 3
B. 4
C. 12
D. 36
Answer:
The answer is actually B.
Step-by-step explanation:
3(1+4x)=12x
(3)(1)+(3)(4x)=12x(Distribute)
3+12x=12x
12x+3=12x
Step 2: Subtract 12x from both sides.
12x+3−12x=12x−12x
3=0
Step 3: Subtract 3 from both sides.
3−3=0−3
0=−3

find the 15th term of the arithmetic sequence 2x+2, 8x-3, 14x-8,...
Answer:
a₁₅ = 86x - 68
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2x + 2
d = a₂ - a₁ = 8x - 3 - 2x - 2 = 6x - 5 , then
a₁₅ = 2x + 2 + 14(6x - 5)
= 2x + 2 + 84x - 70
= 86x - 68

Can someone please tell me how to find the surface area of shapes please I'm literally crying I have a quiz due in 10 minutes and I'm gonna fail please help
Answer:
No Problem
Step-by-step explanation:
Answer:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Step-by-step explanation:
Surface area means, basically the outside of the shape, faces is a fancy way schools use to say sides, for example a cuboid, these look like rectangles but 3D, It has 6 "faces" or sides. And it also has 12 edges. With my school, they usually fill the 3D shapes with cubes to have a way to estimate the size, or they might write it on the sides like 2D shapes. Prisim means a 3D shape that has 2 faces that are the exact same, like a 2D rectangle. Which is a look-alike to the cuboid. SA=2lw+2lh+2hw might look , difficult but it means SA=surface answer, 2LW means length with, 2LH means length hight, and 2HW means hight width.

The price of a CD player was reduced from $80 to $52. What was the percent decrease in the price of the CD player? © 28% 0 35% 54% a 65%
Answer:
35%
Step-by-step explanation:
Given data
Initial price= $80
Final price= $52
% decrease= initial-final/initial*100
% decrease= 80-52/80*100
% decrease= 28/80*100
% decrease=0.35*100
= 35%
Hence the decrease is 35%
