Answer:

Step-by-step explanation:

The statement "The mean decreases as the degrees of freedom increase" is not true about chi-square distributions.

In fact, the mean of a chi-square distribution is equal to its degrees of freedom. It does not decrease as the degrees of freedom increase.

The mean remains constant regardless of the degrees of freedom. This is an important characteristic of chi-square distributions.

Regarding the other statements:

In summary, the statement that is not true about chi-square distributions is that the mean decreases as the degrees of freedom increase.

Answer:

x = 16

Step-by-step explanation:

5 = 1/2(x) - 3

Add 3 to both sides.

8 = 1/2(x)

Rewrite for clarity.

1/2(x) = 8

x/2 = 8

Multiply both sides by 2.

x = 16.

Proof:

5 = 1/2(x) - 3

Substitute variable.

5 = 1/2(16) - 3

Multiply 1/2 and 16.

5 = 8 - 3

Subtract 3 from 8.

5 = 5

\( = > \frac{1}{2} x - 3 = 5\)

\( = > \frac{1}{2}x = 5 + 3\)

\( = > \frac{1}{2}x = 8\)

\( = > x = 8 \times \frac{1}{2} \)

\( = > x = 16\)

As similarity theorem, the value of x that will make the triangles similar by SSS similarity theorem is 77.

Similarity theorem:

In math, similarity theorem refers the line segment splits two sides of a triangle into proportional segments if and only if the segment is parallel to the triangle's third side.

Given,

Here we need to find the t value of will make the triangles similar by the similarity theorem.

For example, we are told that the 2 triangles are similar by SSS theorem.

Here we know that, SSS means Side - Side -Side and it is a congruence theorem which states that the 3 corresponding sides of two triangles have same ratio, then we can say that the two triangles are congruent by SSS theorem

Therefore, in the triangles ,applying the SSS postulate gives;

=> x/35 = 44/20

Then by applying the multiplication property of equality, let us multiply both sides by 35 to get;

=> x = (44 * 35)/20

When we simplify this one then we get,

=> x = 77

Therefore, the value of x is 77.

The variable data refers to the list [10, 20, 30]. After the statement data[1] = 5, data evaluates to [10, 5, 30]. A list is one of the compound data types that Python provides. Lists can contain items of different types, but they are usually all the same type.

Lists are mutable sequences, meaning that their elements can be changed after they have been created. Lists can be defined in several ways, including by enclosing a comma-separated sequence of values in square brackets ([ ]).

The elements of a list can be accessed using indexing, with the first element having an index of 0. The second element has an index of 1, the third element has an index of 2, and so on. To change the value of an element in a list, you can use indexing with an assignment statement.

For example, the statement `data[1] = 5` changes the second element of the `data` list to 5. Therefore, after this statement, the `data` list will be `[10, 5, 30]`.

Answer:

what is it asking for you can't see the hole answer.

Answer:

x = -10

Step-by-step explanation:

The interior angles of a triangle adds up to 180 degrees

⇒ 180 = 90 + 29 + (71 + x)

add like terms:

⇒ 90 + 29 + 71= 190

⇒ 180 = 190 + x

subtract 190 from each side

⇒ 180 - 190 = 190 - 190 + x

⇒ -10 = x

If a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is two

When a categorical variable that has n categories is to be included as an independent variable in a linear regression analysis, it must be converted to n - 1 dummy variables. The reason for this is that including all n categories as dummy variables would cause perfect multicollinearity in the regression analysis, making it impossible to estimate the effect of each variable.In this case, the set of categories {Red, Blue, Green, Yellow} has four categories. As a result, n - 1 = 3 dummy variables are required to represent this variable in a linear regression. This is true since each category is exclusive of the others, and we cannot assume that there is an inherent order to the categories.The dummy variable for the first category is included in the regression model by default, and the remaining n - 1 categories are represented by n - 1 dummy variables. As a result, the number of dummy variables that are required to represent the categorical variable in the regression model is n - 1.

Thus, if a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is two .

x must be less than 9 for the inequality to be satisfied. Hence, x 9 is the solution set.

An inequality is a mathematical statement that compares two quantities or expressions using inequality symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).

To solve the inequality, we want to isolate the variable x on one side of the inequality symbol. We start by adding 5 to both sides of the inequality to get:

31 + 5 > -5 + 4x + 5

36 > 4x

Next, we divide both sides of the inequality by 4 to get:

36/4 > 4x/4

9 > x

Thus, we have found that x must be less than 9 for the inequality to be satisfied. Hence, x 9 is the solution set.

Answer choice D correctly represents the solution set. Answer choices A, B, and C are all incorrect because they do not correctly represent the inequality we found: x < 9.

Step-by-step explanation:

The function f(t) is defined as e raised to the power 5t plus 4t plus the natural logarithm of the quantity t squared plus 3 times the constant c, raised to the power of 7, plus t times e raised to the power of -1 plus 5 times e raised to the power of 6.

Given a function:

f(t)=e5t+4t+7ln(t2+3c)+te-1+5e6

where c is a constant.

The solution to the question is shown below.

Step 1: We have given a function:

f(t)=e5t+4t+7ln(t2+3c)+te-1+5e6

We have to find the number of words we have to write to express this function in words.

Step 2: Solution

f(t) = et5+4t + ln(t²+3c)⁷ +te-1+5e⁶

Where,

et5+4t = exponential function

ln(t²+3c)⁷ = natural logarithmic function

te-1 = linear function

e⁶ = exponential function

Therefore, f(t) can be expressed in words as:

The function f(t) is defined as e raised to the power 5t plus 4t plus the natural logarithm of the quantity t squared plus 3 times the constant c, raised to the power of 7, plus t times e raised to the power of -1 plus 5 times e raised to the power of 6.

Step 3: Conclusion

Hence, the function f(t) can be expressed in words with:The function f(t) is defined as e raised to the power 5t plus 4t plus the natural logarithm of the quantity t squared plus 3 times the constant c, raised to the power of 7, plus t times e raised to the power of -1 plus 5 times e raised to the power of 6.

The fish has a final position of + 2 meters.

In this problem we find the initial position of the fish (s), in meters, and its change (Δs), in meters. The final position (s'), in meters, of the fish is found by means of the following difference equation:

s' = s + Δs

If we know that s = - 9 m and Δs = - 11 m, then the final position of the fish is:

s' = - 9 m + 11 m

s' = + 2 m

Fatuma invested approximately $17,500 at 6% and the remaining amount $1,000 at 15%.

Here, we have,

Let's denote the amount invested at 6% as 'x' and the amount invested at 15% as '18500 - x' (since the total investment is $18,500).

The interest earned from the amount invested at 6% would be (6/100) * x = 0.06x.

The interest earned from the amount invested at 15% would be (15/100) * (18500 - x) = 0.15(18500 - x).

According to the given information, the total interest earned is $1,200. We can set up the following equation:

0.06x + 0.15(18500 - x) = 1200

Now, let's solve the equation to find the value of 'x':

0.06x + 2775 - 0.15x = 1200

-0.09x + 2775 = 1200

-0.09x = 1200 - 2775

-0.09x = -1575

x = (-1575) / (-0.09)

x ≈ 17500

Therefore, Fatuma invested approximately $17,500 at 6% and the remaining amount, $18,500 - $17,500 = $1,000 at 15%.
