The mathematical statement of the expression t - 3 is the difference between t and 3

Expressions are mathematical statements that are represented by variables, coefficients and operators

The algebraic expression is given as

t - 3

The above mathematical representation is an algebraic expression that is already in its most simplified form

This means that the algebraic expression cannot be further simplified

However, the algebraic expression can be rewritten as a mathematical statement

Recall that, we have

t - 3

The pronunciation of the above expression is:

t minus 3

In expressions, minus represents difference

So, we have

t minus 3 can be represented as the difference between t and 3

Hence, the representation of the algebraic expression given as t - 3 is the difference between t and 3

It's a way to gauge how widely apart each data point is from the mean. The standard deviation formula comes in two different forms: Standard deviation for the population When you can measure the entire population or the entire collection of data, you use the population version of the formula. Experts in statistics have determined that measurements that fall within a 2 SD range of the true value are more accurate than those that do not..

The equation for the given function passing through (0,5) and (4,0) is equal to y = (-5 /4)x +5.

As given in the question,

As shown in the graph drawn we have

Equation for the given function passing through ( x₁ , y₁ ) = (0, 5) and

( x₂ , y₂ )=( 4, 0) is given by :

( y - y₁ )/ (x -x₁ )=( y₂ - y₁ )/( x₂ - x₁ )

Answer: c

Step-by-step explanation:

The solution set for the inequality is p > -9.4. See attachment below for the graph.

An open circle is used when the inequality sign involved is ">" or "<". That is, it is used for numbers that are less than or greater than.

An arrow shaded to the right means the solution set is greater than a given value, while an arrow shaded to the left means the solution set includes all values that are less than a given value.

Given the inequality, p + 3.6 > −5.8, solve for p:

p + 3.6 > −5.8

Subtract 3.6 from both sides

p + 3.6 - 3.6 > -5.8 - 3.6

p > -9.4

Thus, the solution set would be all the values that are greater than -9.4. The graph is shown below.

Step 3:           1, 7

Step-by-step explanation:

The y intercept of the function f(x) = 2^2−4 is 0

The x intercept of the function f(x) = 2^2−4 is 0 or 2

The zeros of the function f(x) = 2^2−4 is 0 or 2

When f(x) = f(-4) then the function f(-4) = 48

When f(x) = 2 then x = -0.4142 or 2.142

given data

f(x) = 2^2 − 4

The y intercept

f(x) = 2^2−4

y = 2^2−4

at x = 0

y = 2 ( 0 ) ^2 - 4 ( 0 )

y = 0 - 0

y = 0

The x intercept

f(x) = 2^2 − 4

y = 2^2− 4

at y = 0

0 = 2^2− 4

0 = 2x( x - 2 )

2x = 0    OR     x - 2 = 0

x = 0      OR     x = 2

We need to calculate the 10% of 20. By definition, a% is:

Where a can be any positive number. In this case a = 10, then:

In mathematics, the word "of" is reserved for the product. Then 10% of 20 is just:

Solving this leads to 2.

Answer:

1/2.

To convert to a percentage we multiply by 100:

Number of shares after split is 5/2 times the pre split value =800*5/2 = 2000

The dimensions of the region which enclose the maximum area is a side of 162 feet and vertical segment of 108 feet

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the side parallel to the vertical segment and y represent the other side. If the farmer has 648 feet of fencing, hence:

x + x + y + y + x = 648

3x + 2y = 648

y = 324 - 1.5x

Area (A) = xy

A = xy

A = x(324 - 1.5x)

A = 324x - 1.5x²

The maximum area is at A' = 0, hence:

A' = 324 - 3x

324 - 3x = 0

3x = 324

x = 108 feet

y = 324 - 1.5(108) = 162 feet

x = 108 feet, y = 162 feet

Using the probability concept, it is found that:

a) The tree diagram is given by the image at the end of the answer.

b) The probability is of 0.18 = 18%.

c) The probability is of 0.72 = 72%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

For item a in this problem, we have two independent events, hence the tree diagram will contain two nodes, one with each event and it's probabilities.

For item b, since the events are independent, to find the probability of both, we multiply the probability of each, hence:

0.3 x 0.6 = 0.18.

For item c, first we find the probability of none being completed, hence:

(1 - 0.3) x (1 - 0.6) = 0.7 x 0.4 = 0.28.

At least one is complementary to none, hence the probability is given as follows:

p = 1 - 0.28 = 0.72 = 72%.

The fraction of straight section of motor racing circuit is 3/14 miles.

To find the fraction of circuit which is straight, we will perform division. The fraction will be found as - Fraction = length of straight section ÷ total length of motor racing circuit

Keep the values in mentioned relation to find the fraction of circuit which is straight.

Converting the mentioned lengths from mixed fraction to fraction.

Length of motor racing circuit = (6×5 + 5)/6

Length of motor racing circuit = 35/6

Length of straight section of circuit = (4×1 + 1)/4

Length of straight section of circuit = 5/4

Fraction of straight circuit = (5/4)/(35/6)

Simplifying the fraction

Fraction of straight circuit = (5×6)/(35×4)

Performing multiplication in numerator and denominator

Fraction of straight circuit = 30/140

Performing division

Fraction of straight circuit = 3/14 miles

The angles that are supplementary angles are: ∠SRT and ∠SRO

Angles that are supplementary will give us a sum of 180 degrees when we add the two angles together. One is the supplement of the other.

Some examples of angles that are supplementary angles that are formed when two parallel lines are intersected by a transversal include:

Angle SRT and angle SRO are angles that are adjacent to each other because they share a common side SR and a common vertex R. They line on the straight line OT.

Therefore, angle SRT and angle SRO are two angles that are supplementary angles as shown in the diagram attached below where lines NP and QS are parallel lines. The supplementary angles are therefore angle SRT and angle SRO.

99th term of the given arithmetic sequence 7, 3, -1, -5, ... is -385.

We are provided with the arithmetic sequence mentioned below;

7, 3, -1, -5, ................. -385

[tex]a_{n}[/tex] =  [tex]a_{1}[/tex] + (n−1)d

where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term and d is the difference between a term and its previous term.

With the help of provided arithmetic sequence we can write;

[tex]a_{n}[/tex] = -385

[tex]a_{1}[/tex] = 7

d = difference between a term and its previous term = 3 - 7 = -4

Put these values in equation 1 , we will get

-385 = 7 + (n-1) (-4)

392 = 4n -4

4n = 396

n = 99

So we can conclude that the 99th term of the arithmetic sequence 7, 3, -1, -5, ... is -385.

Using vertical angles, Maggie made her mistake when combining the like terms of x, which has a result of -3x and not 3x, hence the correct result is of x = 9.

Vertical angles are two angles that are opposite by the same vertex when two lines cross each other, and they are congruent, that is, they have the same measure.

For this problem, the vertical angles are given as follows:

Since they are congruent, we can solve for the variable x as follows:

4x + 2 = 7x - 25.

Moving all the terms with x to the left side of the equality and all the constant terms to the right side, with opposite signal, we have that:

4x - 7x = -25 - 2

Combining the like terms, it is found that:

-3x = -27.

Here happened Maggie's mistake, as 4x - 7x = -3x, hence the correct solution is given by:
