Given :
The number of goals they scored over the first 7 games of the season are :
3, 7, 3, 0, 5, 8, 2 .
To Find :
The mean number of goals the Strikers scored each game .
Solution :
We know , mean of numbers is given by :
[tex]M=\dfrac{\text{Sum of all numbers}}{\text{Total numbers}}\\\\M = \dfrac{3+7+3+0+5+8+2}{7}\\\\M=\dfrac{28}{7}\\\\M=4[/tex]
Therefore , the mean number of goals the Strikers scored each game is 4 .
Hence , this is the required solution .

Part I: Describe how the account balance of a savings account earning simple interest is determined.
Part ll: Explain the difference between a savings account earning simple interest and a savings account earning compound interest.
Part Ill: Which type of savings account would you open and why?
Answer:
part 1: You start with an annual "simple interest rate," which is the percentage of the principal balance your money earns each year. ... Add the daily interest earned to the balance.
part 2: Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.
part 3: a compound interest account and here's why. When it comes to investing, compound interest is better since it allows funds to grow at a faster rate than they would in an account with a simple interest rate

find an equation of the line passing through the point (5 4) and parallel to the line whose equation is y= 2x-6
Answer:
[tex]y = 2x - 6[/tex]
Step-by-step explanation:
Given
Equation: [tex]y = 2x - 6[/tex]
Required
Determine the equation of Point: (5,4)
First, we need to determine the slope of [tex]y = 2x - 6[/tex]
The general form of an equation is [tex]y = mx + b[/tex]
Where m represents the slope;
Hence; [tex]m =2[/tex]
Since the equation and the point are parallel. then they have the same slope (m).
[tex]m = 2[/tex]
Next, is to determine the equation of the point, using the following formula:
[tex]m = \frac{y - y_1}{x - x_1}[/tex]
Where
[tex](x_1,y_1) = (5,4)[/tex]
So, the equation becomes
[tex]2 = \frac{y - 4}{x - 5}[/tex]
Cross Multiply
[tex]y - 4 = 2(x - 5)[/tex]
Open Bracket
[tex]y - 4 = 2x - 10[/tex]
Make y the subject of formula
[tex]y = 2x - 10 + 4[/tex]
[tex]y = 2x - 6[/tex]
Hence, the equation is [tex]y = 2x - 6[/tex]

What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object
A rotation of 90° counter-clockwise about the origin is defined as the x-coordinate and y-coordinate change places, and the line y = x is the coordinates (-x , y).
To determine the image of the point (-9, -8) after a rotation of 90° counterclockwise about the origin
Suppose, the coordinates are (a,b)
A point (a,b) reflected across the line y = -x will become (-a,b).
Let a = -9 and b = -8
Substitute the values of a and b,
So the coordinates of image (9, -8)
Hence, the coordinates of the image (9, -8) after a rotation of 90° counter-clockwise about the origin.

Robin Hood fooled King John when he gave
him 3/6 of the coins. You could say that he
Input the fraction 1/2 (x) and his output was
3/6 (y). The function that caused that output
was multiplying both the numerator and the
denominator by 3.
Step-by-step explanation:
This is a common knowledge of equivalent fractions.
Multiplying both the numerator and denominator of a fraction by the same quantity does not change the value of the fraction.
Not only multiplication, but division also works. What ever operation performed on the numerator must also be performed on the denominator.

Cows and Chickens
A chicken farmer also has cows for
a total of 30 animals, and the
animals have 66 legs in all.
How many chickens does the farmer have?
Answer:
27 Chickens
Step-by-step explanation:
Represent the chicken with A and the cows with B
Given
[tex]A + B = 30[/tex]
A has 2 legs and B has 4; So:
[tex]2A + 4B = 66[/tex]
Required
Determine A and B
Make B the subject of formula in the first equation
[tex]B = 30 - A[/tex]
Substitute 30 - A for B in the second equation
[tex]2A + 4(30 - A) = 66[/tex]
Open the bracket
[tex]2A + 120 - 4A = 66[/tex]
Collect Like Terms
[tex]2A - 4A = 66 - 120[/tex]
[tex]-2A= -54[/tex]
Divide through by -2
[tex]A = 27[/tex]
Hence, the farmer has 27 chickens

How can you write the statement "Obtuse angles have a greater measure than acute angles" so that it is a good definition?
Answer:
Obtuse angles have a measure that is greater than 90 but less than 180 degrees, while acute angles have a measure that is less than 90 but greater than 0.
Step-by-step explanation:
Obtuse angles have a measure that is greater than 90 but less than 180 degrees because 180 degree angle is a straight angle. Any angle that is greater than 181 but less than 360 degrees is known as a reflex angle. Acute angles have a measure that is less than 90 but greater than 0 because anything with a higher of lower degree of measure would be consider a different angle.
