There is an equal amount of yellow, blue, green, and red marbles in a bag of 32 marbles. If Ed draws 4 marbles out of the bag with replacement, predict how many of the 4 marbles drawn should be blue.
1
4
8
32
Answer:
There are 32 marbles in the bag, and 1/4 of them are blue, so there are 32 * 1/4 = 8 blue marbles in the bag.
When Ed draws 4 marbles out of the bag with replacement, the probability of getting a blue marble on any given draw is 1/4.
The number of blue marbles Ed is expected to draw can be found by multiplying the probability of drawing a blue marble on each draw (1/4) by the number of draws (4):
Expected number of blue marbles = (1/4) * 4 = 1
Therefore, Ed is expected to draw 1 blue marble out of the 4 marbles drawn.
1) 1
Reasoning:
There are 4 different colors of marbles and 32 total marbles. 32/4 is 8, so there will be 8 of each at the start.
Because Ed picks 4 marbles, and there are 4 colors, we will divide 4 by 4 (4/4) and get 1.

Hi,would you please help me to solve this math problem?
How would the length of a circle change if:
a) the radius is increased 2 times
b) the radius is decreased 3 times
c) the diameter is increased 6 times?
Answer:
a) If the radius of a circle is increased 2 times, the length of the circle (circumference) will increase by a factor of 2π or approximately 6.28 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is doubled, then the circumference will also be doubled.
b) If the radius of a circle is decreased 3 times, the length of the circle (circumference) will decrease by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is divided by 3, then the circumference will also be divided by 3 and multiplied by 2π.
c) If the diameter of a circle is increased 6 times, the length of the circle (circumference) will increase by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = πd, where d is the diameter. If the diameter is multiplied by 6, then the circumference will also be multiplied by 6π
Step-by-step explanation:
pls Mark me As a brainlist
a) length of the circle increased by 2 times.
b) length of the circle decreased by 3 times.
c) length of the circle increased by 6 times.
Length of a circle that is the circumference of the circle is given by the formula = 2πr ( let's say C)
a) Given that the radius of the circle is increased by two times.
R = 2r
Required length of the circle = 2πR = 2π(2r) = 2×2πr = 2C
Hence, the length of the circle will be increased by 2 times.
b) Given that the radius is decreased by 3 times.
R= r/3
Required length of the circle = 2πR = 2π(r/3) = (2πr)/3 = C/3
Hence, the length of circle will be decreased by 3 times.
c) Given that the diameter of the circle is increased by 6 times.
D = 6d = 6×2r = 12r
Required length of the circle = πD= π×12r = 6(2πr) = 6C
Hence, the required length of circle will be increased by 6 times.

The cost that will maximize the demand, considering the quadratic function, is given as follows:
$3.
How to maximize the demand?The quadratic function representing the demand is given as follows:
y = -10x² + 60x + 180.
The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:
x = -b / (2a)
The coefficients of the quadratic function in this problem are given as follows:
a = -10, b = 60.
The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:
x = -60/(2 x (-20))
x = 3.

Write an equation that gives the proportional relationship of the graph.
A) y = 30x
B) y = 5x
C) y = 6x
D) y = 1/5x
The solution is, choice B) [tex]y=5x[/tex] represent a proportional relationship.
What is proportional relationship?A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y\div x = k[/tex] or [tex]y = kx[/tex]
here, we have,
we know that,
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

The case A) represent a proportional relationship
choice B) [tex]y=5x[/tex]
Is a linear equation that passes through the origin
therefore
The case B) represent a proportional relationship
choice C) [tex]y =6x[/tex]

In the given triangle, the measure of angle C is 32°
Calculating the measure of anglesFrom the question, we are to determine the value of angle C.
Let half of ∠IAB = a
and half of ∠IBA = b
Then,
a + b + 106° = 180° (Sum of angles in a triangle)
a + b = 74°
Also,
2a + 2b + ∠C = 180° (Sum of angles in a triangle)
2(a + b) + ∠C = 180°
2(74°) + ∠C = 180°
148° + ∠C = 180°
Subtract 148° from both sides
148° - 148° + ∠C = 180° - 148°
∠C = 32°
Hence, the measure of C is 32°
