The significance of the difference between the two groups under comparison will increase as the p-value decreases. The significance of the difference between the two groups under comparison will increase as the t-value rises.

A difference that is "statistically significant" does not necessarily have to be "large, important, or significant in terms of the utility of the finding"; it simply means that there is statistical evidence that there is a difference.

In general, when the null hypothesis H0 is true, our sample results could have happened by random chance alone when the p-value is "high" (i.e. greater than or equal to the significance level).

The value of Isabel's account after three years can be calculated using the future value of the annuity formula.

Isabelle's budget car is:

Reason:

Monthly savings, PMT = $200

Account compound interest, r = 1.7%

t = Account value after 3 years is displayed as increase.

We know that:

[tex]FV =PMT * \frac{[(1+i)^n -1]}{i}[/tex]      --------------------- (1)

Where;

    i = r/12

⇒ n = 12 × t

From the above equation(1), we get:

[tex]FV =200 * \frac{[(1+\frac{1.7}{2} )^{12*3} -1]}{\frac{1.7}{12} }[/tex]

    ≈ 7381.4

Therefore,

The budget cars she can buy, those that require a down payment of less than $7,381.4, which  are:

If 120% of a number is 24, then the number is 5.

percentage, a relative value indicating hundredth parts of any quantity.

We need to find the number whose 120% of a number is 24.

Let the number be considered as x

120% is converted to decimal by dividing 120 with 100

120/100=1.2

Now multiply 1.2 by x which is equal to 24

1.2x=24

Divide both sides by 1.2

x=0.05

Now multiply it with 100 as it is a hundredth part

0.05×100=5

Hence, If 120% of a number is 24, then the number is 5.

Answer:

169

Step-by-step explanation:

You should know that the middle number with the x is double the original number not in expanded form. You should also know that in the expanded form, the last number is the square of the original number. So square(26/2) = 169.

Answer:

r^2 + 26r = (r + 13)^2 - 169

Step-by-step explanation:

r^2 + 26r + (26/2)^2 - (26/2)^2, or

r^2 + 26r + 13^2 - 13^2, or

(r^2 + 26r + 169) - 169

So r^2 + 26r = (r + 13)^2 - 169

Note:  the coefficient of r is 26.  We take half of that, obtaining 13, and then square the result:  13.

all of these option 4 is correct

Answer:

The answer is the ( are )

Step-by-step explanation:

Option C is correct, the parent function represented by the table is f(x) = x.

A relation is a function if it has only One y-value for each x-value.

Looking at the table, we can see that when x is negative, the values of y are negative and increase as x approaches zero.

When x is positive, the values of y are positive and increase as x increases.

Moreover, the values of y increase faster than x.

This behavior is typical of the parent function f(x) = x.

Step-by-step explanation:

The inequality that describes these points is y ≤ -1/2(x) -3. The graph is given the attachment.

To graph a linear inequality in two variables (say, x and y), start with y on one side. Consider the related equation obtained by changing the inequality sign to an equality sign. This equation's graph is a straight line.

If the inequality is strict (< or >), draw a dashed line. If the inequality is not strict (≤ or ≥), draw a solid line.

Finally, choose one point that is not on either line ((0,0) is usually the easiest) and determine whether these coordinates satisfy the inequality or not. If they do, shade the half-plane containing that point. If they don't, shade the other half-plane.

The width of the frame is 2.4 inches

Let w represent the width of the frame

Then the area of the frame is:

(w + 5)(w + 7) = 69.56

Rewrite it in Standard form of a quadratic equation:

w² + 12w + 35 = 69.56

w² + 12w - 34.56 = 0

Use Quadratic Formula to solve for w:

w =  (-b±√(b²-4ac))/(2a)

w =  (-12±√(12²-4×1×(- 34.56)))/(2×1)

w = (-12±√(144+138.24))/(2)

w = (-12±16.8)/2

w = -6 ± 8.4

w = -6 + 8.4 or -6-8.4

w = 2.4 or w = -14.4

Since the width cannot be negative.

The probability of the intersection of the two diagonals chosen lying inside the nonagon is 2/3.

What is the probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event.

In this problem, the event of interest is the intersection of the two diagonals lying inside the nonagon. A nonagon is a 9-sided polygon, so there are 9 total corners, each of which can be one end of a diagonal. Therefore, there are 9 choose 2 = 36 total ways to choose two diagonals.

To find the number of favorable outcomes, we need to find the number of ways to choose two diagonals such that their intersection is inside the nonagon. To do this, we can notice that the diagonals that have an intersection inside the nonagon are the diagonals that connect non-adjacent corners of the nonagon. There are 8 non-adjacent corners, so there are 8 choose 2 = 28 ways to choose two non-adjacent corners.

So the probability of the intersection of the two diagonals lying inside the nonagon is:

P(intersection inside nonagon) = favorable outcomes / total outcomes = 28/36 = 2/3

Hence, the probability of the intersection of the two diagonals chosen lying inside the nonagon is 2/3.

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

These expressions are represented with the help of unknown variables, constants and coefficients. The combination of these three (as terms) is said to be an expression. It is to be noted that, unlike the algebraic equation, an algebraic expression has no sides or equal to sign.

Step-by-step explanation:
