Write a variable expression that represents the following word phrase:

Four less than half the difference of 3 and x​

Answer: 36 years old

Step-by-step explanation:

T=Tanya. M=Marcus

T=M+28

T+6=3(M+6)

T+6-6=3(M+6)-6

T=3(M+6)-6

M+28=3(M+6)-6

M+34=3M+18

34=2M+18

2M=16

M=8

T=M+28

T=8+28

T=36 years old

The current age of Tanya is equivalent to 45 years old.

Given is that Tanya is 28 years older than Marcus. In 6 years, Tanya will be three times as old as Marcus

Assume the initial age of Tanya is {x} years and that of Marcus is {y} years old. So, we can write -

x = y + 28         ....... Eq[1]

x + 6 = 3y         ........ Eq[2]

Using Eq[1] in Eq[2], we get -

y + 28 + 6 = 3y

y + 34 = 3y

2y = 34

y = 17

Than, we can write [x] as -

x = 17 + 28

x = 45

Therefore, the current age of Tanya is equivalent to 45 years old.

The measure of the smaller angle is 23⁰ and the measure of the larger angle is 67⁰.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

So we can say that two angles are complementary if they sum up to 90 degrees.

From the given statement;

y = 3x - 2  -------(1)

y + x = 90  --------(2) (since they are complementary)

substitute for y in equation (2)

3x - 2 + x = 90

4x = 92

x = 92/4

x = 23 ⁰

y = 3(23) - 2

y = 67⁰

Thus, the measure of the smaller angle is 23⁰ and the measure of the larger angle is 67⁰.

The inequality that is equivalent to the given inequality is -10x + 10 < 13  

From the question, we are to determine the inequality that is equivalent to the given inequality

The given inequality is -10(x - 1) < 13

To determine the inequality that is equivalent to this inequality, we will solve the given inequality

Solving the inequality

-10(x - 1) < 13

Apply the distributive property

-10x + 10 < 13

Subtract 10 from both sides of the inequality

-10x + 10 - 10 < 13 - 10

-10x < 3

Divide both sides by -10 and reverse the sign

x > -3/10

From the steps of solving the inequality, the inequality that is equivalent to the given inequality is -10x + 10 < 13  

Hence, the inequality that is equivalent to the given inequality is -10x + 10 < 13

The numbers in the equations are -4 and -26

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

Let the numbers be x and y

A system of linear equations is a collection of at least two linear equations. So, we have the following linear equations

y = 5x - 6

x - y = 22

Substitute y = 5x - 6 in x - y = 22

x -5x + 6 = 22

Evaluate the like terms

-4x = 16

Divide both sides by -4

x = -4

Substitute x = -4 in y = 5x - 6

y = 5 * -4 - 6

Evaluate

y = -26

Hence, the numbers are -4 and -26

Step-by-step explanation:

The inverse of the given function,f(t) = 100 . 2^(t/4) is 4 * log2(x/100).

What is the inverse of a function?

An inverse of a function f(x), is defined as another function that undoes the operations performed on the function. It is denoted by f^(-1).

Calculation of the inverse of a function

We are given a function,

f(t) = 100 . 2^(t/4)

Let us assume that f^(-1) represents the inverse of a function

Replacing f(t) with y, we get,

y = 100 . 2^(t/4)

Now, replace further t with y and y with x

x = 100 . 2^(y/4)

Rearranging, we have,

2^(y/4) = x / 100

Taking log both sides, we get,

(y/4) log 2 = log (x/100)

y/4 = log2(x/100)

y = 4 * log2(x/100)

Further, replace x with t and y with f^(-1), i.e.

f^(-1) = 4 * log2(t/100)

Hence, the inverse of the given function, f(t) = 100 . 2^(t/4) is 4 * log2(x/100).

Answer:

324, 900, 9

Step-by-step explanation:

When a shape has its size increased by a scale factor, the size of its lengths are multiplied by this scale factor, yet its area is actually multiplied by the scale factor squared. This is due to two lengths being multiplied to contribute to the area, not just one. If it was a volume, you would multiply by the scale factor cubed!

Onto the answer, just follow the advice above:

36 * 3^2 = 36 * 9 = 324 square inches,

36 * 5^2 = 36 * 25 = 900 square inches,

36 * 0.5^2 = 36 * 0.25 = 9 square inches.

Step-by-step explanation:

The fraction of the total pies remained is option (A) 23/20 is the correct answer.

In this question,

A host served two pies, one apple and one cherry.

Dinner guests ate twenty-five percent of the apple pie and sixty percent of the cherry pie.

Apple pie = 25%

∴ Remaining = 100% - 25%

⇒ 75%  

⇒ Fraction of apple pie remained is 3/4

Cherry pie = 60%

∴ Remaining = 100% - 60%

⇒ 40%

⇒ Fraction of cherry pie remained is 2/5

Thus fraction of the total pies remained is

⇒ 3/4 + 2/5

⇒ (15+8) / 20

⇒ 23/20

Hence we can conclude that the fraction of the total pies remained is option (A) 23/20 is the correct answer.

Scientific notation of numbers may be defined as the way of representation of bigger numbers into powers of 10. This helps in reducing space as well as it helps in conveniently solving the problem. For example, scientific notation of 92000 may be written as 9.2×10⁴.

Here in the number 7.6×10⁻²⁰ the power of 10 is maximum but with a negative value so it is the least number. Then comes the number 5.5×10⁻¹¹ as its power are also negative but greater than the previous number. Similarly using the above logic, the other numbers will be placed, and the greatest number would be 7.6×10²⁰ as it has the maximum power of 10 that too with a positive sign.

The final step to be performed in the mathematical expression, (Σx)2 is square the sum of the scores

Sum of squares is a statistical method for calculating the dispersion of data points in regression analysis. By deviating the least from the data, the sum of squares can be used to identify the function that fits the data the best. The purpose of a regression analysis is to assess how well a data series can be fitted to a function that could provide insight into the process by which the data series was created. In the world of finance, the sum of squares can be used to calculate the variation in asset values.

A statistical measure of departure from the mean is the sum of squares. Variation is another name for it. The squared differences of each data point are added together to calculate it. The sum of squares is calculated by squaring the separation between each data point and the line of best fit, then adding the results. The line of greatest fit will reduce this value to the minimum.

We first find the sum, and then square the sum.

ΣX = 1 + 0 + 2 + 4 = 7

So,  ΣX + 1 = 8

Mean = ( 4+6+14 )/3 = 8

Mean =  ΣX*f /  Σf = (5*2 + 4*1 + 3*3 + 2*2 + 1*2) / (2+1+3+2+2) = 29/10

Subtract 3 points from the score X=3

Changing the lowest score to a lower one will increase the range.

Let t be the time in hours they drive on the second day.

Their average speed is 64 miles per hour.

⇒ 64 = [x + (544 - x) ] / [3 + t]

⇒ 64 = 544 / 3 + t

⇒ 64(3 + t) = 544

Answer in decimal form = -0.2

Answer as a fraction = -1/5

=========================================================

Explanation:

The term "rate of change" is the same as "slope" for linear equations.

Use the slope formula to get the steps shown below.

[tex](x_1, y_1) = (-3, 3.6) \text{ and } (x_2, y_2) = (5, 2)\\\\m = \frac{y_2 - y_1}{x_2 - x_1}\\\\m = \frac{2-3.6}{5-(-3)}\\\\m = \frac{2-3.6}{5+3}\\\\m = \frac{-1.6}{8}\\\\m = \frac{-16}{80}\\\\m = -\frac{1}{5}\\\\m = -0.2\\\\[/tex]

The decimal value is exact without any rounding done to it.

A slope of -1/5 means we go down 1 unit and to the right 5 units.

slope = rise/run = -1/5

rise = -1 = go down 1

run = 5 = go to the right 5

Based on the 1.5 × IQR rule for outliers, there is no evidence to support the student's claim because there is only one outlier at 58 minutes.

An outlier is also referred to as anomalous data and it can be defined as a numerical value that is either unusually too small or large (big) in comparison with the overall pattern of the numerical values contained in a data set.

IQR is an abbreviation for interquartile range and it can be defined as a measure of the middle 50% of data values when they are ordered from lowest to highest.

Mathematically, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁

Based on the given data set, the following interquartile ranges was calculated by using Excel:

Q₃ = 31.5

Q₁ = 20.5

Now, the interquartile range (IQR) is given by:

IQR = Q₃ - Q₁

IQR = 31.5 - 20.5

IQR = 11

Based on the 1.5 × IQR rule for outliers, we have:

1.5 × IQR = 1.5 × 11 = 16.5

Therefore, our fences will be 16.5 points below Q₁ and 16.5 points above Q₃:

Lower fence = 20.5 - 16.5 = 4.5

Upper fence = 4.5 + 31.5 = 36.

In conclusion, we can reasonably infer and logically deduce that there is no evidence to support the student's claim because there is only one outlier at 58 minutes.
