The rational root theorem, as its name suggests, is used to find the rational solutions of a polynomial equation (or zeros or roots of a polynomial function). The solutions derived at the end of any polynomial equation are known as roots or zeros of polynomials. A polynomial doesn't need to have rational zeros.

Rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and the constant term (the one without a variable) must be divisible by the numerator.

The mean will decrease when the rent decrease.

The median will stay the same.

It's important to note that a mean simply means the average of a set of numbers that are given. The mean is the average of the given numbers and is calculated by dividing the total number of numbers by the sum of the given numbers. A data set's mean (average) is calculated by adding all of the numbers in the set and then dividing by the number of values in the set.

Mean = (sum of all observations divided by the total number of observations)

In this case, the rents are 735, 935, 960, 995, 1005, 1050, 1065, 1075, 1100, 1120 and one of the people moves, and his rent changes from $735 to $535.

In this case, changing 735 to 535 will make the average lower.

On the other hand, the median isn't affected as it's still 1057.50.

Answer:

It looks like it could be the first one

Step-by-step explanation:

How to solve problems like this:

KEY FORMULA: y=mx+b

The b respresents the Y-INTERSCEPT (The number that the line crosses on the y-axis. In this case, it is 1. In the first graph, the line is crossing the 1 on the y-side.)

Mx = Slope. In this case, it is 3/2.

How to graph this: First, plot (0, 1), because 1 is the y-interscept. Then, since the slope is a POSITIVE, after the 1, you go right two, then up three. Then you draw your line.

The double facts of 8 + 7 = 15 is (7 + 7) + 1 and ( 8 + 8) -1.

Double facts:

A doubles fact is a number sentence that repeats the same addend, such as 3 + 3 = 6 or 8 + 8 = 16.

Here we have to find the double facts of the equation:

Equation:

8 + 7 = 15

When a number is added to itself the result is twice that number

Example:

2 + 2 = 2× 2 = 4

3 + 3 = 2× 3 = 6

5 + 5 = 2× 5 = 10

Similarly, we have to solve for 8 + 7 = 15

So 8 + 7 = 7 + 7 + 1

= ( 7 + 7) +1

In the same manner, we can also do that:

8 + 7 = 8 + 8 -1

= (8 + 8) -1

Therefore the double facts of the equation are ( 7+7)+1 and (8+8)-1.

Answer:

x less than or equal to -2

Step-by-step explanation:

I believe that's the answer

Answer:

  x < -2

Step-by-step explanation:

You want the domain of a function graphed as a curve with an open circle at x=-2, which is the right end of the curve.

The domain is the horizontal extent of the graph. It is the set of values for which the relation is defined.

The open circle at (x, y) = (-2, 0) means that point is not part of the graph. All x-values to the left of that point have corresponding y-values, so the extent of the graph can be said to be ...

  x < -2

The domain of the relation is x < -2.

Using doubles plus one fact the sum of 8 + 8 + 1is equal to 17 it is done by simply adding 1 to the given number.

Doubles plus one fact is used to add numbers which are next to each other.

Doubles plus one fact is simply done by doubling the number and adding one to it.

The sum of 8 + 8 can be determined by using doubles plus one fact as:

Simply add 1 in 8 + 8 + 1 to get the result required.

8 + 8 + 1 = 17

Therefore by using doubles plus one fact the sum of 8 + 8 + 1 is equal to 17.

Answer:

All real numbers

Step-by-step explanation:

The exponential function showing the relationship between t and y is y = 310000(1.048)⁺

From the question, we have the following parameters that can be used in our computation:

Initial population = 310000

Rate of growth = 4.8%

These parameters can be represeted as

a = 310000 and r = 4.8%

An exponential function is represented as

y = a(1 + r)⁺

Substitute the known values in the above equation, so, we have the following representation

y = 310000 (1 + 4.8%)⁺

Evaluate

y = 310000(1.048)⁺

Hence, the function is y = 310000(1.048)⁺

Total = ⁿCᵣ

Where

n = 30 and r = 5

Substitute the known values in the above equation

Total = ³⁰C₅

Apply the combination formula

ⁿCᵣ = n!/(n - r)!r!

0.01023 is the probability of obtaining a success

Since we are dealing with a binomial probability distribution. We are going to use the binomial distribution formula for determining the probability of x successes:

P(X = r) = nCr . p^r  . q^n-r

Given: number of trial (n) = 17, probability of success (p) = 0.6, X=15

probability of failure (q) = 1 - 0.6 = 0.4

P(X = 15) = 17C15 × 0.6¹⁵ × 0.4¹⁷⁻¹⁵

P(X = 15) = 17C15 × 0.6¹⁵ × 0.4²

P(X = 15) = 136 × 0.6¹⁵ × 0.16

P(X = 15)  = 0.01023

Therefore, the probability of obtaining a success is 0.01023

ΔABC and ΔRQM are congruent triangles. They are congruent by either ASA or AAS.

Two triangles are said to be congruent if their all corresponding sides are equal and all corresponding angles are equal in measure.

For the given question,

We know that the sum of all angles of a triangle is 180°.

For ΔABC,

∠A + ∠B + ∠C = 180°

42° + 53° + ∠C = 180°

95° + ∠C = 180

∠C = 85°

For ΔABC and ΔRQM,

∠A = ∠R

∠C = ∠Q

AB = RM

So, by the AAS postulate, ΔABC and ΔRQM are congruent triangles.

For ΔRQM,

∠R + ∠Q + ∠M = 180°

42° + 85° + ∠M = 180°

∠M = 53°

For ΔABC and ΔRQM,

∠A = ∠R

∠B = ∠M

AB = RM

So, by the ASA postulate, ΔABC and ΔRQM are congruent triangles.

Therefore, ΔABC and ΔRQM are congruent triangles. They are congruent by either ASA or AAS.

What is Right angle traingle?

A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees. The combined angles of the other two are 90 degrees. The triangle's base and perpendicular sides both include the right angle. The longest of the three sides, known as the hypotenuse, is the third side.

we know that;

By applying the Pythagorean Theorem;

[tex]c^2 = a^2 + b^2[/tex]                                                                 .............................(1)

Area of the square says A1;

A1 = a^2 unit^2                                                           ...............................(2)

Area of the square says A2;

A2 = b^2 unit^2                                                         .................................(3)

Area of the square says A1;

A3 = c^2 unit^2                                                         ..................................(4)

Replace the A1, A2, and A3 values in the equation 1 ;

A3 = A1 + A2

(Area of 1) + (Area of 2) = (Area of 3).

From the information, Newton and Descartes

The simplification of the expression 6 to the power of 2 - (8 - 4) to the power of 2 + 7 = ? gives -262108

Simplification is a way of determining an answer for a complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus, etc.

Given: the expression, 6 to the power of 2 - (8 - 4) to the power of 2 + 7 = ?

This can be written as 6² -  (8 - 4)²⁺⁷. Thus:

6² -  (8 - 4)²⁺⁷ = 6² -  4⁹

                      = (6×6) - (4×4×4×4×4×4×4×4×4)
