In a group of 24 students attending a party, the average age is 25.3 years. A 27-year-old student joins the party.
The new average of the students is 25.368.
What is the average?In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
Given that, in a group of 24 students attending a party, the average age is 25.3 years.
A 27-year-old student joins the party.
So, the new average is (24×25.3+27)/25
= 634.2/25
= 25.368
Therefore, the new average of the students is 25.368.

3.6= − a/0.8 − 1.6 − 0.8 a −1.6
The value of a for the given expression will be -3.31.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 3.6= − a/0.8 − 1.6 − 0.8 a −1.6. The value of a will be calculated as below,
3.6 = − a/0.8 − 1.6 − 0.8 a −1.6
3.6 + 1.6 + 1.6 = -a / 0.8 - 0.8a
6.8 = ( -a - 0.64a ) / 0.8
5.44 = -1.64a
a = -3.31
Therefore, the value of a will be -3.31.

Step-by-step explanation:
One root being i, an imaginary number is throwing me off.. but I can give it a shot if youd like.
So a coefficient is the number Infront of the X. so for 6X^2, the coefficient is 6.
It says the Leading Coefficient is 3. The one option for that is 3x^4, so that will be the in the first blank.
The exponents now (the little numbers) start with 4 and go down 1 after each block. Which means the last two blocks will have no little numbers since it would be 1 and 0. Those don't need exponents.
For the block after the 21x^2, we have two choices. Either 6x or 2x
For the last block we have two choices also.
8 or 24
To find if it's 6x or 2x...
Its showing roots of -2, i, and 4 with multiplicity of 1, which means

The difference between the area of Figure A and the area of Figure B is 2ft, So correct option is A.
What do you mean by grid?A square grid is a two-dimensional pattern formed by a series of equally spaced horizontal and vertical lines that intersect at right angles, creating a regular array of squares. It can be thought of as a flat, two-dimensional lattice with a consistent spacing between the lines. A square grid can be used to represent many things, such as a map, a game board, a city plan, or a spreadsheet. In mathematics and geometry, a square grid is often used to represent coordinate systems, where each intersection of horizontal and vertical lines corresponds to a specific point with a unique set of coordinates. Square grids are also used in graphic design and art as a foundation for creating patterns, textures, and compositions.
