What is a inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols.

A difference between two values indicates whether one is smaller, larger, or simply not equal to the other.

"A connection is termed an inequality if two real numbers or algebraic expressions are connected by the symbols ">," "," "," or "."

A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true.

According to the statement, the value of Z-Stat is +2.10. And we must find the P value when H0 is rejected only in the upper tail. The Z-stat is defined as the Z-score, which indicates how much a given value differs from the standard deviation.

The Z-score, also known as the standard score, is the number of standard deviations a given data point is above or below the mean.

And we know that the P-Value is calculated by converting your statistic into a Z-Score.

As a result, the p value is 0.0179.

So, When ZSTAT = +2.10, the resulting P-Value is 0.0179.

The ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.

What is the constant of variation?

The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.

We have,

         x         y

         2         10

         4         24

         6         36

To determine whether y varies directly with x, you need to see if the ratio of y to x is constant for all the data points.

If y varies directly with x, then the ratio y/x will be constant for all the data points. In this case, you can write an equation for the direct variation in the form y = kx, where k is the constant of variation, which is equal to the ratio y/x.

If the ratio y/x is not constant for all the data points, then y does not vary directly with x.

so, let's see the k constant of variation,

k =  y/x

k = 2/10 =1/5

k = 4/24 = 1/6

k = 6/36 = 1/6

so,  k = 1/5, k=1/6, k=1/6.

Hence, the ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.

By solving the given equation, we know that Courtney withdrawals $25.75 each time from her bank account.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the value of the variable x is 7.

So, we have the equation:

400-3x=322.75

Now, solve the equation for x to get the amount Courtney withdrawals each time:

400-3x=322.75

-3x = 322.75 - 400

-3x = -77.25

x = -77.25/-3

x = $25.75

We can tell that the investment results after 4 years will be $761 with the help of compound interest.

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.

It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it so that interest is generated the next period on the principal amount plus any accumulated interest.

In finance and economics, compound interest is common.

So, we have an initial investment of %600.

And the interest is 6% which will be compounded quarterly for 4 years.

Then the amount we will receive after 4 years is:

(Refer to the table attached below)

So, the amount we will get after 4 years is $761.39.

Rounding off: $761

Given that,

Show that each component of isom (r²) is either a translation or a rotation using the findings from section 3.7.

An isometry of R² is a mapping T:R²⇒R² which preserves distance.

The formula for the distance between x and y is

d(x,y)=|y-x|=√(y₂-x₂)²+(y₁-x₁)²

The preservice means,

d(x,y)=d(T(x),T(y))

A translation is an isometry.

Since,

d(Tv(x),Tv(y))=|(xv)-(y-v)|=d(x,y)

The rotation matrix, for rotating by an angle Θ, is defined as,

cosΘ     -sinΘ

The annual interest rate of the bank account is 2.3%

Let's check the equation for each year.

Compound Interest earned amount

A = P( 1 + r/n)ⁿˣ

A = accumulated amount

P =  original amount deposited

r =  interest rate

n = times it compounds per year

x = years

when Amount = $736.80, x = 4 years and r% → r/100

736.80 = P(1 +[(r/100)/1] ¹×⁴

736.80 = P(1 + r/100)⁴

when Amount =$788.82 , x = 7 years and r% → r/100

788.82 = P(1 +[(r/100)/1] ¹×⁷

788.82 = P(1 + r/100)⁷

using the 1st equation:

736.80 = P(1 + r/100)⁴

P = 736.80 /[(1 + r/100)⁴]

Substitute on the Using 2nd equation

788.82 = P(1 + r/100)⁷

788.82 =  736.80 /[(1 + r/100)⁴] * (1 + r/100)⁷

788.82 =  736.80 * [(1 + r/100)⁷/(1 + r/100)⁴]

788.82 = 736.80 * (1 + r/100)³

788.82/736.80 = (1 + r/100)³

∛788.82/736.80 = ∛ (1 + r/100)³

∛788.82/736.80 = (100 + r)/100

100 ∛788.82/736.80 = 100 + r

100 ∛788.82/736.80 - 100 = r

Answer:

Step-by-step explanation:

In order for the ratio of volumes of a cylinder, cone, and sphere to be true, the radius of each solid would have to be equal. This is because the radius is a factor in the volume formulas for all three solids:

Volume of cylinder: πr^2h

Volume of cone: (1/3)πr^2h

Volume of sphere: (4/3)πr^3

If the radius is equal in all three solids, then the volumes will be in the same ratio as the given ratio, regardless of the values of h or the surface area. Therefore, the correct answer is : The radius and the height.
