The given statement: ANCOVA measures the relationship strength between two variables and how much they change together is FALSE because it is used to determine if differences between groups on a dependent variable are due to the independent variable or due to the covariate.

Analysis of covariance (ANCOVA) is actually a statistical technique used to compare means of a dependent variable across different groups, while controlling for the effects of one or more continuous variables, called covariates.

It is similar to ANOVA (analysis of variance), but with the addition of covariates. ANCOVA is not a measure of how much two variables change together or the strength of their relationship.

Instead, it is used to determine if differences between groups on a dependent variable are due to the independent variable or due to the covariate.

If x represents a positive integer and x<7, then the values of x = {1,2,3,4,5,6}

The x represents a positive integers

Positive integers are the integers greater than 0. In number line the positive number will be at the right side of the 0. The negative integers are the integers less than 0. In number line the negative number will be at the left side of the 0.

The given inequality is

x<7

The inequality is the mathematical expression represents the relation between the two values that is not equal

Here x is less than 7 and a positive integer

Therefore,

x = {1, 2, 3, 4, 5, 6}

Hence, if x represents a positive integer and x<7, then the values of x = {1,2,3,4,5,6}

The class width that should be used for constructing the frequency distribution is 5.

To determine the class width for constructing a frequency distribution with 5 classes, we need to calculate the range of the variable and divide it by the number of classes.

Range = Maximum value - Minimum value

= 35 - 10

= 25

Class width = Range / Number of classes

= 25 / 5

= 5

Therefore, the class width that should be used for constructing the frequency distribution is 5.

The correct answer is (a) 5.

Applying the law of cosine, the largest angle in the given triangle, to the nearest whole degree, is: 99°.

Law of cosine is, c² = a² + b² - 2ab(cosC)

Let,

Plug in the values into the formula for the law of cosine:

26² = 15² + 19² - 2(15)(19)(cosC)

676 = 586 - 570(cosC)

676 - 586 = -570(cosC)

90 = -570(cosC)

90/-570 = cos C

-0.1579 = cos C

C = cos^(-1)(-0.1579)

C = 99°

The largest angle = 99°

Answer:

i don't really know but I love pizza

Answer:

Step-by-step explanation:

I see three equations that represents the first step. All the others (I think) have flaws of one kind or another.

Third

The third one divides both sides of the equation by 3. All that remains on the left is what is inside the brackets. 24/3 becomes 8 which what equation 3 says.

x + 6 = 24/3

x + 6 = 8

Fourth

Shows how the distributive property is performed. It does this with great care. The right side is not affected.

3*x + 6*3 = 24       is what is the result. It is a good first step.

Five

This one is a little iffy. It is more like the second step. You have taken the fourth choice and removed the brackets.  If you can do this in your head, I think it counts.  I'm not sure how to answer what you should do. You're darned if you do and darned if you don't. My opinion is that it is perfectly OK but your marker may not agree.

The solution of the expression is,

⇒ S = - 5100

Since, An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

We have to given that;

Sequence is,

⇒ ∑ n = 1 to n = 4 [ 100 (- 4)ⁿ⁻¹ ]

Now, We get;

⇒ a (n) = [ 100 (- 4)ⁿ⁻¹ ]

Replace n to n + 1;

⇒ a (n + 1) = 100 (- 4)ⁿ

And, For n = 1;

⇒ a (n) = [ 100 (- 4)ⁿ⁻¹ ]

⇒ a (1) = [ 100 (- 4)¹⁻¹ ]

⇒ a (1) =  100

And, Common ratio = - 4

Hence, The sum of geometric ratio is,

⇒ S = 100 (1 - (- 4)⁴) / (1 + 4)

⇒ S = 100 (1 - 256) / 5

⇒ S = - 5100

Thus, The solution of the expression is,

Since both sides of the equation are equal, we have completed the basic step of the proof, showing that P(1) is true.

a.) The statement P(1) is obtained by substituting n=1 into the equation. So, P(1) would be: 1³ = (1(1 + 1) / 2)²

b.) To show that P(1) is true, we need to prove that both sides of the equation are equal:

Left side: 1³ = 1

Right side: (1(1 + 1) / 2)² = (1(2) / 2)² = (2 / 2)² = 1² = 1

Since both sides of the equation are equal, we have completed the basic step of the proof, showing that P(1) is true.

a) The equation is not true for n = 1, so P(1) is false.

b) The positive integer n, 13 + 23 + … + n3 = (n(n + 1) / 2)²" is not true for n = 1

a) To find P(1), we substitute n = 1 into the equation given:

13 = (1(1 + 1) / 2)²

13 = (1 / 2)²

13 = 1/4

The equation is not true for n = 1, so P(1) is false.

b) To complete the basic step of the proof, we need to show that P(1) is true.

However, we have just shown that P(1) is false.

This means that the statement "for the positive integer n, 13 + 23 + … + n3 = (n(n + 1) / 2)²" is not true for n = 1.

Therefore, the proof cannot proceed and is incomplete.

The length of f is 11.9 ft.

We have,

d = 5.2 inches, e = 6.8 inches and ∠F=166°.

Using the law of cosines as:

f² = d² + e² - 2(de)(cos(F))

So, f² = (5.2)² + (6.8)²  - 2(5.2)(6.8)cos(166)

f² = 27.04 + 46.24 - 66.56 cos (166)

f² = 73.28 - 66.56 cos 166

f = √(73.28 - 66.56 cos 166)

f ≈ 11.9 inch.

Lucia saved the total amount of $100 and Ben saved $50.  Lucia saved twice as much as Ben so for every $1 Ben saved, Lucia saved $2.

Lucia and Ben have saved a total of $150. To solve this problem, we need to determine how much each person saved. We know that Lucia saved twice as much as Ben, so for every $1 Ben saved, Lucia saved $2. Since they have saved a total of $150, we can set up a proportion to solve for Ben's amount. $2:$1::$100:$x We can solve for x to find Ben's amount saved. $2x = $100, so x = $50. Therefore, Lucia saved $100 and Ben saved $50. Lucia saved twice as much as Ben so for every $1 Ben saved, Lucia saved $2.
