If a square has an area of 450 square inches then according to Area = 2(length of a side), the length of one side of that square will be 225 inches.

The formula of Area of a Square is ,

area = side × side = side² square units

whereas the perimeter of square is = 4 x side

A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at right angles or at 90 degrees.

let the length of a side of a square is x

area of square is = 450 square inches

as area of square is found as

Area = 2(length of a side)

2x = 450 square inches

x =450/2

x=225 inches

so the length of each side of square is 225 inches.

The number of subscribers in 2008 will be 110845988.

From the information, in 1985, there were 285 cell phone subscribers in the small town of glenwood. the number of subscribers increased by 75% per year after 1985.

It should be noted that the number of years between 1985 and 2008 will be:

= 23 years.

Therefore, the number of subscriber in 2008 will be:

Equation for each situation are A = 59 -7t and B = 34 -2t and t<5 is the interval of time.

Two or more expressions with an Equal sign is called as Equation.

Snowman A starts at 59 inches and decreases height at 7 inches per hour.

The height can be represented as A = 59 -7t

Snowman B starts at 34 inches and decreases height by 2 inches per hour. That height can be represented by B = 34 -2t

A is taller than B.

A > B

59 -7t > 34 -2t

add 7t-34

25 > 5t

Divide by 5

5 > t

A will be taller than B when t < 5.

Answer: A

Step-by-step explanation: To solve this problem, we can set up a system of equations to represent the information given in the problem. Let x represent the cost of a plate of spring rolls, y represent the cost of a plate of chicken tenders, and z represent the cost of a plate of pretzel dippers.

The first group spent $23 on 2 plates of chicken tenders and 1 plate of pretzel dippers, so the equation for this group is:

2y + z = $23

The second group spent $30.75 to buy 3 plates of spring rolls and 1 plate of chicken tenders, so the equation for this group is:

3x + y = $30.75

The third group spent $22.25 on one of each appetizer, so the equation for this group is:

x + y + z = $22.25

Now that we have three equations, we can use algebraic techniques to solve for the value of x, which represents the cost of a plate of spring rolls.

First, we can solve the second equation for y:

y = $30.75 - 3x

Substituting this expression for y into the first equation, we get:

2($30.75 - 3x) + z = $23

Solving for x, we find that x = $7.75.

Therefore, the cost of a plate of spring rolls is $7.75, so the answer is A.

A The line will become less steep.

B The line will shift right 2 units.

C The line will shift up 2 units.

D The line will shift left 2 units.

E The line will shift down 2 units.

The equation of line parallel to y = -3 passing through (2,6) is y = 6

The slope-intercept form of straight line is used to find the equation of line. It is given as y =mx + b

where m is a slope of line

b is y-intercept

According to the question,

The required line is parallel to line y = -3

Slope of given line : m₁

m₁ = 0

When two lines are parallel to each other then their slopes are equal

Therefore , slope of required line is m₂ =  m₁ = 0

Also , given that the line is passing through the coordinate (2,6)

So , 6 = 0(2) + b

=> b = 6

Using the Central Limit Theorem for proportions, the correct option is:

E. The statistic is biased.

What is Central Limit Theorem?

The central limit theorem in probability theory proves that, even if independent random variables are not normally distributed in themselves, in many cases, when they are added together, their properly normalised sum tends toward a normal distribution.

The central limit theorem states that the distribution of the sample means will be roughly normally distributed if you have a population with mean and standard deviation and take sufficiently large random samples from the population with replacement.

The Central Limit Theorem establishes that for a proportion p in a sample of size n:

- The expected value is[tex]$\mu=p$[/tex].

- The standard error is [tex]$s=\sqrt{\frac{p(1-p)}{n}}$[/tex]

In this problem, the expected value is different of the expected of [tex]$\mu=p$[/tex], hence, the statistic is biased, and the correct option is [tex]$\mathbf{E}$[/tex].

The probability distribution that she or he is on duty on Saturday or Sunday will be 0.7

What is probability distribution ?

A frequency distribution that has been idealised is a probability distribution.

An individual sample or dataset is described by its frequency distribution. It's the number of times in the dataset that each potential value of a variable appears.

The probability of occurrence of a value determines how frequently it appears in a sample. Probability is a value between 0 and 1 that indicates the likelihood that something will happen:

A value will occur more frequently in a sample the higher its likelihood.

The probability of a value is more particularly the relative frequency in an indefinitely large sample.

Probability distributions are theoretical since it is not feasible to obtain infinitely large samples in practise.

Let the people work on Sunday = sun = 4

Let the people work on Saturday = sat = 3

total no. of doctors are 10

so the probability distribution of people work on either Sunday or Saturday will be :

The y-intercepts for the models are equal to 13.2.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

P1 = (x1, y1) and P2 = (x2, y2)

y=1/3x+4 is the equation of line passing through (3, 5) and parallel to -x+3y=6

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

-x+3y=6

3y=6+x

Divide both sides by 3

y=2+1/3x

y=1/3x+2

slope is 1/3

In parallel lines the slope will remain same

We need to find the equation of line passing through (3, 5) and parallel to 3y=6+x
