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.

How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First of all, we would find the slope of this lines;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (3 - 2)/(3 - 0)
Slope (m) = 1/3
At data point (0, 2) and a slope of 1/3, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y = x/3 + 2
At data point (0, -1) and a slope of 1/3, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y = x/3 - 1

2 Sasha believes her soccer team plays better at away games than at home games. Her team played 12 games at home and 12 games away. She recorded the wins over this season. Based on these results, what is the probability for home and away wins? Is she right about her team playing better away? Show your work. Place: Home Away
Step-by-step explanation:
To calculate the probability of home and away wins, we need to know how many wins the team had at home and away, respectively.
Let's assume that the team won x games at home and y games away, where x and y are unknown variables. Then we know that:
x + y = total number of wins (which we'll denote as W)
x + (12 - y) = 12 (the number of home games)
(12 - x) + y = 12 (the number of away games)
Solving these equations for x and y, we get:
x = (W + 12) / 2 - 12
y = (W + 12) / 2 - 12
Now, let's say the team won 8 games in total. Then, using the equations above, we can calculate that:
x = 2 (i.e., they won 2 games at home)
y = 6 (i.e., they won 6 games away)
Therefore, the probability of a home win is 2/12 = 1/6, and the probability of an away win is 6/12 = 1/2.
Based on these calculations, Sasha is correct in her belief that the team plays better away. The probability of an away win is higher than the probability of a home win.

The three vehicles shown below are driving down the street at a constant velocity of 5 m/s. The blue car has a mass of 700 kg. The red car has a mass of 1800 kg. The silver pickup truck has a mass of 3500 kg. Annie-Drew wants to make a line graph showing the relationship between the kinetic energy and mass of the cars traveling at a constant velocity. What would the graph look like?
Answer:
Step-by-step explanation:
As the change in speed of both cars is zero therefore tangential acceleration of both cars will be zero .
now centripetal acceleration is given by
a=v2/r
where, r= radius and v= linear velocity ,
for blue car ab=302/r
for grey van ag =152/r
radius is same for both as they round the same turn ,
So, ab /ag = 30 2/15
2 =4 or a
b =4a/g
The graph represents a relation where x represents the independent variable and y represents the dependent variable. a coordinate plane with points at negative 5 comma 1, negative 3 comma 0, 0 comma negative 3, 2 comma 3, 5 comma negative 1, and 5 comma 1 Is the relation a function? Explain. No, because for each output there is not exactly one input No, because for each input there is not exactly one output Yes, because for each output there is exactly one input Yes, because for each input there is exactly one output
Answer:
To determine whether the relation is a function or not, we need to check if each input value (x) is associated with exactly one output value (y).
Looking at the given set of points (-5, 1), (-3, 0), (0, -3), (2, 3), (5, -1), and (5, 1), we can see that some of the input values are associated with more than one output value. Specifically, the input value of 5 is associated with two different output values: -1 and 1.
Therefore, the relation is not a function because there is not exactly one output value for each input value.
The correct answer is: No, because for each input there is not exactly one output.

A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the park are 12 inches wide by 20 inches long. A rectangular area of the park for swing sets is 0.5 inch wide by 2 inches long on the scale drawing.
What is the actual length of the swing set area of the park?
Enter your answer in the box.
The actual length of the swing set area of the park is ______ feet.
Answer: The actual length of the swing set area of the park is 25 ft long and 100 ft wide.
For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For the given case, it is given that Real dimension of a rectangular park: 600 ft by 1000 ft In drawing, it was of 12 inches by 20 inches. Let the scale that the drawing is using be k feet to s inches, then.
Since it is given that 600 ft: 12 inches and 1000 ft: 20 inches, thus, we get: Thus, every foot is reduced 0.02 times in drawing.
Now, it is given that in drawing, the rectangular area for swing sets is 0.5 inch to 2 inch. Let its real length was L and real width was W. Then we have:
Since these are only magnitudes, and unit was converted from feet to inches, so we have L = 25 feet and W = 100 feet
Thus, the actual length of the swing set area of the park is 25 ft long and 100 ft wide
Answer:
The dimensions of the park on the scale drawing is 12 inches and 20 inches.
Dimension
Actual dimensions:
Park = 600 feet by 1000 feet
Swing set = 25 feet by 100 feet
Swing set on the scale drawing= 0.5 inch by 2 inches
Hence:
Dimension of park on drawing:
Width = 600×1/50
Width = 12inches
Length = 1000×1/50
Length= 20inches
Inconclusion the dimensions of the park on the scale drawing is 12 inches and 20 inches.

Find 7/12 of 36.
Pls help! Will mark brainly!
Answer:
21
Step-by-step explanation:
You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.
Here's a little tip for you. Any number can be converted to a fraction if you use 1 as the denominator:
36/1
So now that we've converted 36 into a fraction, to work out the answer, we put the fraction 7/12 side by side with our new fraction, 36/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:
7/12 x 36/1 = 252/12
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 252 and 12 is 12.
We can now divide both the new numerator and the denominator by 12 to simplify this fraction down to its lowest terms.
252/12 = 21
12/12 = 1
When we put that together, we can see that our complete answer is:
21/1
The complete and simplified answer to the question what is 7/12 of 36 is:

can you solve for pi
Answer:
No
Step-by-step explanation:
Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is an irrational number, which means it cannot be expressed as a finite decimal or a fraction. Therefore, it is not possible to solve for pi in the traditional sense.
However, pi can be approximated to a certain number of decimal places using various mathematical methods, such as the Monte Carlo method or numerical integration. The commonly used approximation for pi is 3.14159265358979323846, but the actual value of pi has an infinite number of decimal places and cannot be fully calculated.
Answer:
You can't
Step-by-step explanation:
Pi is already a constant rate if that is what you want to call it. pi is 3.14159265359
Alex has five cups of strawberries. He wants to use / cups of strawberries for a fruit salad and / cups for jam. Does Alex have enough strawberries to make both recipes? Solve this problem any way you choose.
Answer:
Since Alex only has 5 cups of strawberries, he does not have enough to make both recipes.
Step-by-step explanation:
1 3/4 cups of strawberries + 3 1/2 cups of strawberries= 5 1/4 cups of strawberries. Alex needs more strawberries.
Answer:
No.
Step-by-step explanation:
To solve the Yes/No question,
First, write the equation:
5 = [tex]1\frac{3}{4}[/tex] + [tex]3\frac{1}{2}[/tex]
Then convert the mixed fraction to improper ones:
5 = [tex]\frac{7}{4}[/tex] + [tex]\frac{7}{2}[/tex]
Then find the LCM of the denominators 4 & 2 ( = 4 ) and solve:
5 = [tex]\frac{7}{4}[/tex] + [tex]\frac{14}{4}[/tex]
5 = [tex]\frac{7+14}{4}[/tex]
5 = [tex]\frac{21}{4}[/tex]
5 = 5.25
5 < 5.25
So because 5.25 is greater than 5, he doesn't have enough strawberries to make the recipes.

Find the missing side of a right triangle if
a. area = 46cm 2 , base = 23cm
b. area = 120cm 2 , base = 40cm
c. area =12m 2 , base = 20m
Grade#8
Answer:
a. The area of a triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. We know that A = 46cm^2 and b = 23cm. Substituting these values into the formula, we get:
46cm^2 = (1/2)(23cm)(h)
Simplifying, we get:
46cm^2 = 11.5cm*h
Dividing both sides by 11.5cm, we get:
h = 4cm
Therefore, the missing side of the right triangle is 4cm.
b. Using the same formula, we can find the height of the triangle:
120cm^2 = (1/2)(40cm)(h)
Simplifying, we get:
120cm^2 = 20cm*h
Dividing both sides by 20cm, we get:
h = 6cm
Therefore, the missing side of the right triangle is 6cm.
c. Again, using the same formula, we can find the height of the triangle:
12m^2 = (1/2)(20m)(h)
Simplifying, we get:
12m^2 = 10m*h
Dividing both sides by 10m, we get:
h = 1.2m
Therefore, the missing side of the right triangle is 1.2m.
