If the perimeter of the  rectangle is 56m with length 18m the breadth is 10m

You should know that the breath of the rectangle is the two shorter sides of the rectangle.

The perimeter of the rectangle is the distance round the rectangle

In every rectangle, there are 2 Lengths and 2 breadths

This implies that the perimeter is

P= L+B+L+B

P=2L+2B

This implies that

56=2(18)+2B

⇒56=36+2B

56-36=2B

20=2B

Making B the subject of the relation we have

B=20/2

B=10m

Therefore the breadth of the rectangle is 10m

The solution for the given system of equations is:

x = -63

y = 10

Here we want to solve the following system of equations:

x + 3y = -33

-4x + 5y = -38

To solve the system by substitution, we first need to isolate one of the variables in one of the equations, I will isolate x on the first equation so we get:

x = -33 - 3y

Now we can replace this in the other equation, so we will get:

-4x + 5y = -38

-4*(-33 - 3y) + 5y = -38

Now we can solve this for y, we will get:

-4*-33 - 4*-3y + 5y = -38

132 + 12y + 5y = -38

17y = -38 - 132

17y = 170

y = 170/17 = 10

y = 10

The value of x is given by:

x = -33 - 3y

x = -33 - 3*10 = -63

So the solution is x = -63 and y = 10.

The solution of the inequality is greater than or equal to 18. The number of fruit snacks that were in the bag is 18.

What is the inequality?

In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given inequality is

X÷3  ≥  6

Rewrite left side expression:

X/3 ≥  6

Multiply both sides by 3:

X ≥  6 × 3

X ≥ 18

The value X is greater than or equal to 18.

Therefore the number of fruit snacks that were in the bag is 18.

The equation of slope intercept form is y = 3/2x + 12 if a line passes through the point (-6,3) and has a slope of 3/2.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The slope, m, is a measure of how steep a line is. The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

Given

A line passes through the point (-6,3)

and has a slope of 3/2

Slope intercept form

A statistical test called a t test is employed to compare the means of two groups. It is frequently employed in hypothesis testing to establish whether a procedure or treatment actually affects the population of interest or whether two groups differ from one another.

The Independent Samples t Test compares the means of two separate groups to see if there is statistical support that the population mean values are statistically significantly different.

What are quartile ranges?

The interquartile range in descriptive statistics reveals the spread of your distribution's middle half.

Any distribution that is sorted from low to high is divided into four equal portions using quartiles. The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set.

Median marks is the marks secured by 50% of students.

Hence, if there 120 students and the median marks is 73, the number of students who got more than 73 is 50% of 120, which is 60.

Q1 or the first quartile range is the marks obtained by 25% of students.

Hence, 25% of 120 students scored 55 and 75% of 120 students scored more than 55, which is 90.

For the 80 students in evening classes, 25% of the secured grade less than 45, the first quartile, which is 25% of 80, that is 20.

Similarly 50% of 80 students scored grade more than between 45 and 82, which is 40.
