Answer:

B

Step-by-step explanation:

3/5 == 0.6

Which part of the line is 0.6?

A < 0.5 so there's no way A can be the answer.

C > .75 so it can't be the answer either.

D > 1.5 so it can't be the answer either.

B is the only answer left and it sits just right in front of 0.5, which is close to 0.6.

Answer:

To determine the total number of nitrogen atoms on the right-hand side of the chemical equation, we need to examine the nitrogen-containing compounds:

HNO3(aq) and NO2(g)

In HNO3(aq), there is 1 nitrogen atom. Since we have 4 moles of HNO3 in the equation, we multiply the nitrogen atom count by 4.

In NO2(g), there are 2 nitrogen atoms. Again, we have 2 moles of NO2, so we multiply the nitrogen atom count by 2.

Total number of nitrogen atoms on the right-hand side:

4 moles of HNO3 * 1 nitrogen atom/mole of HNO3 = 4 nitrogen atoms

2 moles of NO2 * 2 nitrogen atoms/mole of NO2 = 4 nitrogen atoms

Adding these two values together, we get:

4 nitrogen atoms + 4 nitrogen atoms = 8 nitrogen atoms

Therefore, there are a total of 8 nitrogen atoms on the right-hand side of the chemical equation.

The completed sequence is: 3/k, 3/k, 3/k, 9/2k.To complete the sequence of numbers with a constant difference between adjacent numbers, we can calculate the common difference by subtracting the first term from the second term.

Let's denote the missing terms as A and B.

The given sequence is: 3/k, A, B, 9/2k.

The common difference can be found by subtracting 3/k from A or B. Therefore:

A - 3/k = B - A = 9/2k - B.

To simplify, we can equate the two expressions for the                     common difference:

A - 3/k = 9/2k - B.

Next, we can solve for A and B using this equation.

Adding 3/k to both sides gives:

A = 3/k + 9/2k - B.

Now, we can substitute the value of A into the equation:

3/k + 9/2k - B - 3/k = 9/2k - B.

Simplifying further, we have:

9/2k - 3/k = 9/2k - B.

Cancelling out the common terms, we find:

-3/k = -B.

Multiplying both sides by -1, we get:

3/k = B.

The shaded region of the rectangle is 242.9 cm² and the shaded region of the sector is 7.1 square units.

Question 17) is a figure of a rectangle and two inscribed circles.

The area of a rectangle is expressed as: A = length × width

The area of a circle is expressed as: A = πr²

Where r is the radius.

To determine the area of the shaded region, we simply subtract the areas of the two circles from the area of the rectangle.

Area = ( Length × width ) - 2( πr² )

Area = ( 40 × 10 ) - 2( π × 5² )

Area = ( 400 ) - 2( 25π )

Area = 400- 50π

Area = 242.9 cm²

Area of the shaded region is 242.9 squared centimeters.

Question 18) is the a figure a sector of a circle and a right triangle.

The area of a sector is expressed as: A = (θ/360º) × πr²

The area of a triangle  is expressed as: A = 1/2 × base × height

To determine the area of the shaded region, we simply subtract the areas of the triangle from the area of the sector.

Hence:

Area = ( (θ/360º) × πr² ) - ( 1/2 × base × height )

Plug in the values:

Area = ( (90/360º) × π × 5² ) - ( 1/2 × 5 × 5 )

Area = 25π/4 - 12.5

Area = 7.1

Therefore, the area of the shaded region is 7.1 square units.

Option III "E(y) = B₀ + B₁x₁ + B₂x₂ + B₃x₃, where x₁ = 1 if treatment B, x₁ = 0, otherwise; x₂ = 1 if treatment C, x₂ = 0, otherwise; x₃ = 1 if treatment D, x₃ = 0, otherwise." is a correct multiple regression equation that can be used to analyze these data. So the option III is correct.

Randomized design involving four treatments: A, B, C, and D.

So total number of treatments = 4(A, B, C, D)

So the number of dummy variable is required = 4 - 1

The number of dummy variable is required = 3

The three variables would be x₁ x₂ and x₃ and the fourth treatment scenario would be represented if all three were zero.

So the option III is correct because this is a correct multiple regression equation because it contains all the necessary components to define a linear regression model.

Specifically, it contains a dependent variable (y), a constant (B₀), and three independent variables (x₁, x₂, x₃). Additionally, each of the independent variables is either assigned a value of 1 or 0 depending on the treatment, which is how a linear regression model is typically constructed.

The solution to the problem is that the number "x" must be less than or equal to -3.9 in order for the sum of "a number times 10 and 20" to be at most -19.

What is Algebraic expression ?

An algebraic expression is a mathematical phrase that can contain variables, constants, and operators (such as addition, subtraction, multiplication, and division) that are used to represent quantities and their relationships.

Let's use algebra to solve this problem.

Let's call the number we're trying to find "x".

The sum of "a number times 10 and 20" can be written as "10x + 20".

So, we can translate the statement "the sum of a number times 10 and 20 is at most -19" into an equation:

10x + 20 ≤ -19

Now we can solve for x:

10x + 20 ≤ -19

Subtract 20 from both sides:

10x ≤ -39

Divide both sides by 10:

x ≤ -3.9

Therefore, the solution to the problem is that the number "x" must be less than or equal to -3.9 in order for the sum of "a number times 10 and 20" to be at most -19.

Answer:

The answer is B. 298? im not sure if it was supposed to be ≈ or not

I pretty sure the answer is C

One possible answer is: 1, 8, 17, 32, 4, 12

I don't know if there's a methodical way to get this answer. I used trial and error. I started with 1 and looked through the list to see what adds to 1 to get a perfect square. That would be 8 since 1+8 = 9 = 3^2

The process is repeated but this time for 8. After a bit of guess and checking, we see that 8+17 = 25 = 5^2.

Then after 17 is 32 because 17+32 = 49 = 7^2.

Keep doing this until all of the values are used up. If you get stuck, then try backtracking to a previous branch/path where everything worked and try another fork in the road. If that doesn't work, then try starting the sequence with a completely different value (instead of 1).

Answer:

1/8

Step-by-step explanation:

There are 24 coins total. 3 of them are quarters. So Jillian has a 3 in 24 chance of picking up a quarter. Simplifying 3/24 we get 1/8

The probability of randomly picking a quarter is P = 0.125

If we assume that all the coins have the same probability of being randomly picked, the probability of picking a particular type of coin is equal to the quotient between the number of coins of that type that we have, and the total number of coins.

In this case, we have 3 quarters, and a total of:

T = (6 + 7 + 8 + 3) = 24

Then the probability of randomly picking a quarter is:

P = 3/24 = 0.125

The maximum height of the parabolic arch is 100 feet.

How to draw graph?

The graph of a function f in mathematics is the collection of ordered pairs where display style f(x)=y. These pairs are Cartesian coordinates of points in two-dimensional space and so form a subset of this plane in the typical situation when x and f(x) are real integers.

The equation of the parabolic arch is y = -x + 20x. To graph this equation, we can plot a series of points by plugging in different values of x and solving for y.

For example, if x = 0, then y = -0 + 20(0) = 0.

If x = 10, then y = -10 + 20(10) = 100.

If x = 20, then y = -20 + 20(20) = 200.

We can plot these points on the graph and connect them with a smooth curve to obtain the graph of the parabolic arch:

To find the maximum height of the arch, we can look for the highest point on the graph. This occurs when x = 10, and the maximum height is

y = 100 feet.

Therefore, The maximum height of the parabolic arch is 100 feet.

x and y have the values 7 and 7√2, respectively.

The sides of a right triangle with 45-degree acute angles have a unique ratio of 1:1:2.

We can use this information to determine the values of x and y because the base is specified as being 7.

Let's give the perpendicular side the value of x, and the hypotenuse the value of y.

The perpendicular side (x) and the base (7) have the same length because the acute angles are both 45 degrees.

Consequently, x = 7.

We can determine that x:y:2x using the ratio of 1:1:2.

When we enter the value of x, we may calculate y:

7:y:√2(7)

Simplifying even more

AB = AC because of the definition of an isosceles triangle. option A is correct.

D. Since Point M is drawn as the midpoint of BC, hence:

BM = CM because of the definition of a midpoint. Option D is correct.

AM ≈ AM because of the Symmetric Property is wrong. Option E is wrong.

C) The side - side - side (SSS) triangle congruence theorem states that if all the sides of two triangles are equal, then they are congruent triangles.

Since BM = CM, AM = AM and AB = AC, hence ΔABM = ΔACM because of the SSS triangle congruence criterion

ΔABM = ΔACM because of the SAS triangle congruence criterion is wrong. Option C is wrong.
