You randomly draw a marble from a bag, record its color, and then replace it. You draw a red marble 3 out of 20 times. What is the experimental probability that the next marble will be red? Write your answer as a fraction, decimal, or percent. The experimental probability that the next marble will be red is
Answers
Answer:
3/20 or 0.15 or 15%
Step-by-step explanation:
Since 3 red marbles were drawn out of 20 outcomes, the probability the next marble will be red is 3/20. If you convert it to a decimal it will be 0.15, and if you convert it to a percent it will be 15%.

Carpet Plus installs carpet for $100 plus $8 per square yard of carpet. Carpet World charges $75 for installation and $10 per square yard of carpet. Find the number of square yards of carpet for which the cost including carpet and installation is the same.
Answers
Answer:
12.5 square yards.
Step-by-step explanation:
Let a square yard of carpet = x
The cost of installing a carpet is given by;
100 + 8x
The charge for installation
75 + 10x
The number of square yards of carpet for which the cost including carpet and installation is the same is given by;
100 + 8x = 75 + 10x
100 - 75 = 10x - 8x
25 = 2x
x = 25 / 2
x = 12.5 square yards.

The distance between slits on a diffraction grating is 0. 60 mm, and one of the angles of diffraction is 0. 30°. The light forms a second-order bright band. How large is the path difference? 1047 nm 1571 nm 3142 nm 6284 nm.
Answers
The path difference will be 1571 nm
What will be the path difference?Now for the constructive interference, the formula is given
[tex]\rm dsin\theta==n\lambda[/tex]
here,
d = is the distance between slits.=060mm
θ = is the angle of diffraction=0.30 Degree
n = is the order of fringe=2
λ = is the path difference.
[tex]\lambda=\dfrac{(dsin\theta)}{n}[/tex] [tex]\lambda=\dfrac{(0.60\times10^{-3}\times sin(0.30)}{2} = 1.57\times10^{-6}[/tex]

Find the equivalent rate:
300 miles in 20 seconds to miles per minute.
30 miles per min
15 miles per min
3 miles per min
Answers
Step-by-step explanation:
300/20 × 3/3 = 900/60
* 60 sec is 1 min therefore you want to get 60 secs in the denominator. In order to get that, you need to multiply.
900/60 divided by 60/60 is 15/1.
So 300m/20sec = 900m/60sec = 900mpm
If we're to do the same for all then it would be:
30m/20sec = 90m/60sec = 90mpm
15m/20sec = 45m/60sec = 45mpm
3m/20sec = 9m/60sec = 9mpm
what the midpoint between the point 2,6 and "-4,6
Answers
Answer: (-1, 6)
Step-by-step explanation:
Use the midpoint formula:
(Xm, Ym) = ([x1 + x2]/2, [y2 + y1]/2)
(Xm, Ym) = ([2 + -4]/2, [6 + 6]/2)
(Xm, Ym) = (-2/2, 12/2)
(Xm, Ym) = (-1, 6)
The midpoint is (-1, 6)
difference between mass and weight

Mass is how much "matter" something is. Weight is this with respect to gravity. Therefore, if you took a ball to the moon, its mass would not change because the amount of matter is unaffected but the weight will change because the Earth and the Moon have different gravitational pulls.

Based on the vertical angles theorem we can assume that the angles are equal to each other so:
7x-25 = 4x + 2
Now find the value of x
Subtract 4x to both sides
3x - 25 = 2
Add 25 to both sides
3x = 27
Divide by 3 to isolate x
x = 7

Answers
Option second [tex]\rm (w-2.5)(w+2.5)[/tex] and option fourth [tex]\rm (-4v-9)(-4v+9)[/tex] are the products that result in a difference in squares
It is required to identify which products result in a difference of squares.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We know that:
[tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]
In option first:
[tex]\\\rm= (5z+3)(-5z-3)\\\rm =-(5z+3)(5z+3)\\\rm =-(5z+3)^2[/tex]
It is not the difference between squares.
In option second:
[tex]\rm = (w-2.5)(w+2.5)\\\rm = (w^2-2.5^2)[/tex] By using [tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]
It is the difference between squares.
Similarly, in option third:
[tex]\rm = (8g+1)(8g+1)\\\rm = (8g+1)^2[/tex]
It is not the difference between squares.
Similarly, in option forth:
[tex]\rm = (-4v-9)(-4v+9)\\\rm = (4v+9)(4v-9)\\\rm = (4v)^2-9^2[/tex]
It is the difference between squares.
Similarly, in option fifth:
[tex]\rm = (6y+7)(7y-6)\\\rm = 42y^2+13y-42[/tex]
It is not the difference between squares.
Similarly, in option sixth:
[tex]\rm = (p-5)(p-5)\\\rm = (p-5)^2[/tex]
It is also not the difference between squares.
Thus, option 2 and option 4 are correct.

Answers
Complete question is;
Vickie conducts a survey of home builders to determine the average cost of building a new home. She samples 10 home builders who are building in the town in which she lives. Under which conditions will her sample be a representative sample? Select two options:
A) The builders were chosen at random.
B) The population included only builders who build in Vicki’s town.
C) The population included builders who build homes in any town.
D) The population included builders who do not build homes in Vicki’s town.
E) The builders were referred to Vicki by the realtor who will be selling the houses.
Answer:
Options A & B are correct.
A) The builders were chosen at random.
B) The population included only builders who build in Vicki’s town.
Step-by-step explanation:
Looking at the question, we see that Vickie wanted to determine the cost of building a new home in the town in which she lived. Now, she sampled builders who are building in the town in which she lives and thus, it makes the sample more representative.
However, the random method of choosing the builders would help to remove any lingering biases that may arise.
Thus, we can conclude that the builders were chosen at random and that it included only those who build in her town.
Thus, options A & B are correct.
Answer:
A)The builders were chosen at random., B)The population included only builders who build in Vicki’s town.

The profit function, P(x), revenue function, R(x), and cost function, C(x), are related by the equation P(x)=R(x)−C(x). Andrew has determined that the revenue and cost functions for a new product line at his business are given by these functions.
R(x)=5x
C(x)=1200+3x
What is the profit function for Andrew’s new product line?
P(x)=2x−1200
P(x)=2x+1200
P(x)=8x−1200
P(x)=8x+1200
Answers
Answer:
The answer is P(x)8x-1200
Step-by-step explanation:
The profit function for Andrew’s new product line will be P(x) = 2x - 1200. Then the correct option is A.
What is a profit?A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.
The profit is given as,
Profit = Revenue function - Cost function
Andrew has determined that the revenue and cost functions for a new product line at his business are given by these functions.
R(x) = 5x
C(x) = 1200 + 3x
Then the profit function for Andrew’s new product line will be
P(x) = R(x) - C(x)
P(x) = 5x - 1200 - 3x
P(x) = 2x - 1200
The profit function for Andrew’s new product line will be P(x) = 2x - 1200. Then the correct option is A.
