Based on the two-way table, there seems to be a relationship between the type of books Julia's friends like best and the number of books they have read this month, A. Yes, because those who like fiction read one book at a rate four times that of those who read non-fiction books.
What is a two-way table?A two-way table, also called a contingency table, is a statistical table that shows the observed frequency for two variables.
The rows of a two-way table indicate one category and the columns indicate the other category.
For instance, based on the two-way table, one can observe that 80% of Julia's friends prefer fiction while 20% prefer non-fiction.
Among those who read 1 book this month, 80% read fiction against 20% who read non-fiction. Similarly, among those who read 2 books this month, the same 80% read fiction against 20% who read non-fiction.
The number of students who prefer fiction = 60
The number of students who prefer non-fiction = 15
The number of fiction-preferring students who read 1 book this month = 40, which is 80% of the total (40/50 x 100).
The number of fiction-preferring students who read 2 books this month = 20, which is 80% of the total (20/25 x 100).
Thus, we can conclude that Option A is correct.

Riders must be at least 42 inches tall to ride the coaster. Write an addition inequality to determine how much taller William must be to ride the coaster. Let x be the variable representing how much taller
An addition inequality to determine how much taller William must be to ride the coaster is, Height of William + x ≥ 42.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, Riders must be at least 42 inches tall to ride the coaster, and 'x' be the variable representing how much taller William should be.
Therefore, Height of William + x ≥ 42 is an inequality that may be used to calculate how much taller William has to be in order to ride the coaster.

In AABC, AB = AC and AP 1 BC. If AB= (2x + 3) cm, AC = (3y-1) cm, BP = (y + 1) cm and PC = (x + 2) cm find the values of x and y.
Answer:
x = 1y = 2Step-by-step explanation:
Given isosceles triangle ABC with AB≅AC, altitude AP, and AB=(2x+3), AC=(3y-1), BP=(y+1), and PC=(x+2), you want the values of x and y.
Isosceles triangleCorresponding parts of ∆ABP and ∆ACP are congruent, so we have ...
2x +3 = 3y -1
x +2 = y +1
SolutionSubtracting twice the second equation from the first gives ...
(2x +3) -2(x +2) = (3y -1) -2(y +1)
-1 = y -3 . . . . simplify
2 = y . . . . . . add 3
Substituting into the second equation, we have ...
x +2 = 2 +1

The volume formula for a cylinder is V=πhr^2. The volume formula for a cone is V=(πhr^2)/3. You might notice that the formulas are very similar; the only difference is the divided by three at the end. Because we are going from cylinder to cone, we have to multiply by three instead of dividing. Doing this, we get 3*3=9.

Find the radius of a circle that has a sector area of 165.6 cm2 and an angle measure of 129*. Round your answer to the nearest tenth.
To find the radius of a circle given the area of a sector and the measure of the central angle of the sector, we can use the formula:
radius = sector area / (central angle measure / 360)
In this case, the sector area is 165.6 cm2 and the central angle measure is 129*. Plugging these values into the formula gives us:
radius = 165.6 / (129 / 360)
= 165.6 / (129 / 360)
= 165.6 / (0.3583)
= 462.9 cm
Rounding this value to the nearest tenth gives us a radius of approximately 463 cm.

What is the solution of the equation 8x 3y 5 and 3x 2y 5 answer?
The solution of the equation is x = 1 and y = 0.
We can solve this equation using the substitution method.
First, subtract 5 from both sides of the equation to isolate the x and y terms:8x - 3y = 0
3x - 2y = 0
Next, divide both sides of the first equation by 8:
x = (3/8)y
Substitute this expression for x into the second equation:
3(3/8)y - 2y = 0
Simplify:
(-13/8)y = 0
Divide both sides by -13/8:
y = 0
Now, substitute y = 0 into the first equation:
8x - 3(0) = 0
Simplify:
8x = 0
Divide both sides by 8:
x = 0
Therefore, the solution of the equation is x = 1 and y = 0.

What is the discriminant of the quadratic equation 2x 5x^2 1?
The discriminant of the quadratic equation 2x + 5x² = 1 is 24.
The discriminant of a quadratic equation is the value calculated from the coefficients of the quadratic equation and it gives information about the nature of the roots of the equation. The discriminant can be used to determine the number and type of solutions/roots of the equation.
-If the discriminant is greater than zero, the equation has two distinct, real solutions (or roots).
-If the discriminant is equal to zero, the equation has one real solution (or root).
-If the discriminant is less than zero, the equation has no real solutions (or roots), only complex solutions.
The discriminant of the quadratic equation ax² + bx + c = 0 is b² - 4ac.
Plug in the values and solve for the discriminant of the quadratic equation 2x + 5x² = 1.

The size of the large tank is 6 liters and the size of the small tank is 3 liters.
What is the size of each type of tank?The first step is to form a system of equations using the information provided in the question:
3l + 2s = 24 equation 1
2l + 3s = 21 equation 2
Where:
l = volume of the large tank s = volume of the small tankThe elimination method would be used to solve the equations:
Multiply equation 1 by 2 and equation 2 by 3:
6l + 4s = 48 equation 3
6l + 9s = 63 equation 4
Subtract equation 3 from equation 4:
5s = 15
Divide both sides of the equation by 5
s = 15 / 5
s = 3 liters
Substitute for s in equation 1 :
3l + 2(3) = 24

What is inequality?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

What is an integer?An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
