Using the combination formula, it is found that there are 3300 ways to choose the songs.
The order in which the musics are chosen is not important, hence the combination formula is used to solve this question.

��,�Cn,x is the number of different combinations of x objects from a set of n elements, given by:

Answers
The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet)
What is elevation?
The elevation is the height of an object or point above a given reference point, usually sea level. It is often used to describe the height or altitude of a geographic location, such as a mountain peak or a city, and is commonly measured in feet or meters.
In the context of elevation, | -7 | feet would mean the vertical distance between the point at -7 feet and sea level (0 feet).
The vertical distance between two points is calculated by taking the absolute value of the difference between their elevations. So, in this case, the absolute value of -7 is 7, which means the point is 7 feet below sea level.
The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet).

Answers
Answer:
b is correct
Step-by-step explanation:
The product of the functions M(x) and n(x) is x³+ 4x².
To find the product of the two functions, M(x) = x² + 4x and n(x) = x, we need to multiply them together.
So, (mn)(x) = M(x) × n(x)
Substituting the given functions:
(mn)(x) = (x² + 4x) × x
Now, we can simplify the expression by applying the distributive property of multiplication:
(mn)(x) = x × x² + x × 4x
Simplifying further:
(mn)(x) = x³ + 4x²
Therefore, the product of the functions M(x) and n(x) is x³+ 4x².

Step-by-step explanation:
The relations involved in solving this figure are ...
linear pairs are supplementarythe angle sum for the quadrilateral is 360°__
The linear pair at lower left gives us a relation we can solve for x:
x +(3x -24) = 180
4x = 204
x = 51
Then the sum of angles inside the quadrilateral is ...
w +(x +15) +(2x -10) +(3x -24) = 360
w +(51 +15) +(2(51) -10) +(3(51) -24) = 360
w +66 +92 +129 = 360
w = 360 -287 = 73
Angle W is 73°.

Additional comment
The remaining angles are supplementary to those inside the quadrilateral:
v = 180° -w = 107°
y = 180° -92° = 88°
z = 180° -66° = 114°

A multiple regression model with four explanatory variables is estimated using 25 observations resulting in SSE = 660 and SST = 1,000. The value of adjusted R2 is the closest to Multiple Choice o 0.79 o 0.21 o 0.66
Answers
The value of adjusted R^2 is the closest to 0.66. So the option d is correct option.
In the given question,
A multiple regression model with four explanatory variables is estimated using 25 observations.
SSE = 660 and SST = 1,000.
We have to find the value of adjusted R^2.
We know ,
R^2 = SSE/SST
R^2 = 660/1000
R^2 = 0.66
and, we know ,\(R_{adj}^2 \ngtr R^2\) and should be close to R^2.
So, adjusted R^2 should be close to 0.66.
Note :
\(R^2_{adj}\) = 1- (n-1)/(n-p-1) (1-R^2)
where , n = no. of observations and p = no. of independent variables .
So, \(R^2_{adj}\) = 1- (24)/(20) (1-0.66)
\(R^2_{adj}\) = 0.592 which is close to 0.66.
Hence, the value of adjusted R^2 is the closest to 0.66. So the option d is correct option.

The side of a triangle are in the ratio 4:4:3 what kind of triangle is it (b) calculate the smallest angle of the triangle to the nearest degree
Answers
The smallest angle of the equilateral triangle is 60 degrees
If the sides of a triangle are in the ratio 4:4:3, it implies that the lengths of the sides are proportional.
To determine the type of triangle, we examine the side lengths. Since all three sides are equal in length, we have an equilateral triangle.
For an equilateral triangle, all angles are equal. To calculate the smallest angle, we divide the total sum of angles in a triangle (180 degrees) by the number of angles, which is 3:
Smallest angle \(= \frac{180}{3} = 60\)\) degrees.
Therefore, the smallest angle of the equilateral triangle is 60 degrees (to the nearest degree).
