Answer:
Step-by-step explanation:
9/100 i believe as you would multiply 3/10 by 3/10 due to the fact the marble is being replaced so the probability of getting a red marble the second time will be more unlikely. If I'm right please thank me or give me brainly. Hope this helps :)
The probability of drawing two red marbles, if the first marble is replaced after it is drawn, is 9/100.
What is Probability?
It is a branch of mathematics that deals with the occurrence of a random event.
The probability of drawing a red marble on the first draw is 3/10, since there are 3 red marbles out of a total of 10 marbles.
Since the first marble is replaced before the second draw, the probability of drawing a red marble on the second draw is also 3/10.
To find the probability of drawing two red marbles in a row, we multiply the probabilities of the individual events, since they are independent:
P(drawing two red marbles) = P(red on first draw) × P(red on second draw)
P(drawing two red marbles) = (3/10) × (3/10)
= 9/100
Therefore, the probability of drawing two red marbles, if the first marble is replaced after it is drawn, is 9/100.

You are using a 9 inch paint roller to paint a wall of your bedroom. The roller has a dimension of 1 5/8 inches and a nap thickness of 1/4 inch, as shown
Answer:
21.38 square inches
Step-by-step explanation:
Given that You are using a 9 inch paint roller to paint a wall of your bedroom. The roller has a dimension of 1 5/8 inches as diameter and a nap thickness of 1/4 inch, as shown
The nap is the fuzzy materials on the surface roller. How much area does the roller cover in one full revelation
The parameters to be considered are:
Diameter = 15/8 inches
Thickness = 1/4 inches
After one revolution rolling, the dimensions of the length will be:
L = 1/4 + 15/8 + 1/4
L = 19/8 inches.
Let the width be equal to 9 inches
The area covered = L × W
Substitute L and W into the formula
Area = 19/8 × 9
Area = 21.38 square inches
Therefore, the area covered by the roller in one full revelation is 21.38 square inches

In an inventory of 100 sodas, 65 are
diet and 30 are caffeine-free. Of the
diet sodas, 22 are caffeine-free. If a
soda in the inventory is selected at
random, what is the probability that it
is neither diet nor caffeine-free?
Answer:
5% I think
Step-by-step explanation:
Its mostly just a guess but I think its 5%
The probability that it is neither diet nor caffeine-free is 0.13.
What is Probability?Probability is the likeliness of an event to happen.
The number of total sodas = 100
The number of diet soda = 65
The number of Caffeine free sodas = 30
The number of caffeine free sodas out of diet sodas = 22
The number of soda that are neither caffeine nor soda is 100 -65-22 = 13
The probability that it is neither diet nor caffeine-free is 13/100 = 0.13

Answer:
a = 1Step-by-step explanation:
equation given: a - 2(4 - a) = 7a - 12
distribute and expand the equation
a - 8 + 2a = 7a - 12
combine similar terms:
a + 2a - 7a = -12 + 8
simplify:
-4a = -4
a = -4 / -4
a = 1proof that a = 1
a - 2(4 - a) = 7a - 12
1 - 2(4 - 1) = 7(1) - 12
1 - 2(3) = 7 - 12
1 - 6 = -5
-5 = -5 therefore, the a = 1 is correct.
Steps to solve:
a - 2(4 - a) = 7a - 12
~Distribute left side
a - 8 - 2a = 7a - 12
~Combine like terms on the left side
-a - 8 = 7a - 12
~Add 8 to both sides
-a = 7a - 4
~Subtract 7a to both sides
-8a = -4
~Divide -8 to both sides
a = 1/2

Rectangle PQRS is rotated 90° counterclockwise about the origin to create rectangle people are P prime Q prime R prime S prime . What are the coordinates of point R prime
Answer:
R'(4, -1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and reflection.
If a point A(x, y) is rotated 90° counterclockwise about the origin, the new point is A'(-y, x)
From the image attached, below are the location of the points:
P(-3, -1), Q(-1, -1), R(-1, -4) and S(-3, -4)
If point R(-4, -1) is rotated 90° counterclockwise about the origin, its new location would be at R'(4, -1)

Answer:
The correct answer is A. a = 2s - b - c
Step-by-step explanation:
First you multiply 2 on both sides and you will end up with 2s = a + b + c.
Then to isolate a you would subtract both b and c from both sides of the equation as well to end up with your answer of a = 2s - b - c.

Answer:
never true
Step-by-step explanation:
6(x + 1) = 2(5 + 3x)
distribute
6x + 6 = 10 + 6x
combine like terms by subtracting 6x and 6 from both sides
