Answer:
We start with 4 cards. The probability of picking the 4 is 1/4. That card is put back, so we again have 4 cards. The probability of picking the 6 (the number greater than 5) is 1/4.
Therefore, the probability of picking a 4 and then a 6 is (1/4)(1/4) = 1/16.
Answer:
1/16
Step-by-step explanation:
what is the value of this expression
5 (9/12 - 1/4) + 0.5
The answer to this is 3

The same art teacher estimates that he has enough clay for 9 students. Is he correct? Why?
Remember: He has 47 1/3 pounds of clay and wants to give each student 2 1/2 lbs of clay.
*Use compatible numbers to estimate. These are numbers that are close to the actual numbers that you know will divide easily.
Answer:
The art teacher is incorrect.
Step-by-step explanation:
Coming Up with Compatible Estimate Numbers:
The teacher has 47 1/3 pounds of clay. We can round this to 50. Now we have 50 pounds of clay.
Explaining the Operations:
The teacher wanted to distribute the clay by 2.5 lbs. This means we need to divide the amount of clay by 2.5.
Performing the Operations:
Divide 50 by 2.5 ---> 50÷2.5=(5÷2.5)*10--->5÷2.5=2--->2*10=20
Final Conclusion
For every student, the art teacher plans to give 2.5 lbs of clay. This means he will divide his 47 1/3 pounds by 2.5 piles and hand them out to the students. If we round 47 1/3 to 50 (about 2 points higher) and divide 50 by 2.5, you get 20. This means he would have a little less than enough clay for 20 students, not 9. Therefore, the art teacher is incorrect.
****ANOTHER POSSIBLE SOLUTION****
You can also multiply 9 x 2.5 and see if the product is close to 47 1/3. In this case, you can round 2.5 to 3 and proceed with the multiplication. 9*3=27 Since 27 is a lot lower than 47 1/3, the art teacher is incorrect.

Answer:
525
Step-by-step explanation:
If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525
A square picture frame has a round circle cut out to show the picture. What is the area of the picture frame?
Answer:
78.5 cm2
Step-by-step explanation:
The formula for the area of a circle is A = πr^2, where π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
Since the diameter of the circle is 10, we can find the radius by dividing the diameter by 2:
r = d/2 = 10/2 = 5
Now we can plug in the value of r into the formula:
A = πr^2 = 3.14 x 5^2 = 78.5
Therefore, the area of the circle with a diameter of 10 is approximately 78.5 square units.
The area of the given picture frame is 177.5 cm².
Given,
Length of square = 16 cm
The diameter of the circle cut out = 10 cm
We have to calculate the area of the picture frame.
First, we will find out the area of the square.
The area of the square = a² = 16 × 16 = 256 cm²
Now, we will find out the area of the circle that is being cut out from the square.
Area of the circle = πr² = 3.14 × 5² = 78.5 cm²
Then the area of the picture frame = Area of the square - the area of the circle
= 256 cm² - 78.5 cm²
= 177.5 cm²
Therefore, the required area of the square frame is 177.5 cm².

An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment values shown in the table:
Enrollment Month
January February March April May June
Actual 500 400 550 550 750 400
Predicted 410 450 650 650 600 450
Residual 90 −50 −100 −100 150 −50
Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.

Step-by-step explanation:
-2.25 + 0.4x = -2.8
Solve as a simplified mixed number and as a decimal
Answer:
-1 3/8 and -1.375
Step-by-step explanation:
To solve for x in the equation -2.25 + 0.4x = -2.8, we can start by isolating the variable term (0.4x) on one side of the equation:
-2.25 + 0.4x = -2.8
0.4x = -2.8 + 2.25
0.4x = -0.55
Next, we can divide both sides by 0.4 to solve for x:
x = -0.55 / 0.4
x = -1.375
As a mixed number, -1.375 can be written as:
-1 3/8
As a decimal, -1.375 is already in decimal form.
Here are 30 best lifetime baseball batting averages of all time is shown to the right. These data can be graphically displayed as a histogram. Which of the following graphs correctly displays the data from the table? A. Graph A B. Graph B C. Graph C D. Graph D E. Graph E
Answer:
B). Graph B
Step-by-step explanation:
A Histogram is a graphic representation of data using bars varying in height as per the range of values.
In the given question, the second option correctly represents the data provided in the table using a histogram. It portrays the class ranging from 0.320 - 0.329 with an average of 1 in the first bar, from 0.330 - 0.339 with an average of 14 runs in the second bar, and moves so on till 0.360-0.369 correctly. The other options fail to portray the numerical distribution appropriately and hence, option B is the correct answer.

Step-by-step explanation:
The formula for the perimeter of a rectangle: 2(l + w)
Since we have not found x, you would assume it hasn't been doubled yet by the 2. Since the width = 14, it is doubled to 28.
Next, we know from looking at the formula that l and w are added together, so inside the brackets is an addition problem. ( + 28)
Since we know that l = x and l has to be doubled, it will be = (2x +)
If we combine those two equations together it is =
2x + 28 = 48
Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2
what is an equation of the line that passes through the points (4,−3) and (2,−4)
The equation of the line that passes through the points (4,−3) and (2,−4) is y = 1/2x - 5
How to determine the equation of the lineThe general formula for calculating the equation of a line is expressed with the given equation;
y = mx + c
the parameters of the equation are;
y is a point on the y -axis.m is the gradient or slope of the line.x is a point on the x - axis.c is the y - intercept of the line.From the information given, we have;
Slope, m = y₂ - y₁/x₂ - x₁
Substitute the values
Slope, m = -4 - (-3)/ 2 - 4
subtract the values

SOMEONE PLEASE HELP ME ASAP PLEASE!!!
Answer:
L: y= -4x + 17
Step-by-step explanation:
For a line L to pass through two points, we use the slope formula to calculate the slope, m, where
m = (y2-y1) / (x2-x1)
= (9-1) / (2-4)
= 8 / -2
= -4
Next we use the point slope form to find the line equation:
L: (y-y1) = m (x-x1)
substitute (x1,y1) = (4,1)
L: y-1 = -4 (x-4)
Simplify:
L: y = -4x + 16 + 1
L: y= -4x + 17
Check: substitute (4,1)
y = -4(4)+17 = 1 checks
substitute (2,9)
y = -4(2)+17 = 9 checks
so
L: y= -4x + 17
Answer:
y is equal to 5 and x is equal to 11
