Answer:

0.5x(x + 2) = 24

x² + 2x - 48 = 0

x² + (x + 2)² = 100

Step-by-step explanation:

A = bh/2

A = x(x + 2)/2 = 24

0.5x(x + 2) = 24

0.5x² + x = 24

x² + 2x = 48

x² + 2x - 48 = 0

x² + (x + 2)² = 10²

x² + (x + 2)² = 100

Answer = 2 minutes and 15 seconds

1 minute = 60 seconds

60 seconds times 3= 180 seconds

25% of 180 seconds = 45 seconds

180-45=135 seconds

convert into minutes

1 minute = 60 seconds

2 minutes = 120 seconds

135-120=15 seconds

2 minutes and 15 seconds

Answer:

2 mins 15 secs

Step-by-step explanation:

If the original version of the song is 100% in length, then the remix will be 75% of the length of the original, as:

100% - 25% = 75%

Convert 75% into a decimal:

⇒ 75% = 75/100 = 0.75

75% of 3 minutes

= 0.75 × 3

= 2.25 minutes

As there are 60 seconds in a minute,

= 0.25 of a minute = 0.25 × 60 = 15 seconds

Therefore, the length of the remix is 2 mins 15 secs

The coefficient of determination is 0.588 and the percentage of the total variation is 58.8%.

The coefficient of determination (r^2) refers to a measurement used to explain how much variability of one variable can be caused by its relationship to another related variable. It is the fit of goodness and measures how well a statistical model fits the observed data and is a number between 0 and 1. When the value of linear correlation coefficient r is known, the coefficient of determination can be computed simply by squaring r.

Hence if r = 0.767, then the coefficient of determination = r^2 = 0.588

As percentage of the total variation is same as the coefficient of determination (given in percentage) and is given by the R² value = 58.8%. Hence, about 58.8% of variation is explained by the linear relationship between the two variables.

Note: The question is incomplete. The complete question probably is: Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage of the total variation that can be explained by the linear relationship between the two variables. r = 0.767.

Answer:

x = 16/3, y = -1/9

Step-by-step explanation:

4x + 1 = 5(x-3y) - 6

3(x+6y) + 4 = 9y + 19

Simplify both equations

4x + 1 = 5x-15y - 6

-x + 15y = -7

3x + 18y + 4 = 9y + 19

3x + 9y = 15

Now multiply 3 on both sides for the first equation.

(easier for adding both equations)

-3x + 45y = -21

3x + 9y = 15

Add both equations

x cancels out

54 y = -6

y = -1/9

plug in to other equation

3x + 9y = 15

3x - 1 = 15

3x = 16

x = 16/3

Answer:

(a) P = 32.5 feet

(b) P = 108-2x feet

Step-by-step explanation:

Note: Perimeter is the total distance around the border of a shape.

(a)

P = 14' + 27'' + 14' +27'' ; First we have to covert the 27'' (27 inches to feet)

\(27*\frac{1}{12} = \frac{27}{12} =\frac{9}{4}\) = 2.25feet

P = 14'+2.25'+14'+2.25'

P = 32.5' = 32.5 feet

(b)

P = 15'+29'+(15'-x')+3'+7'+3'+(7'-x')+29' ; where x is the overlapping distance of the 2 rectangles of Foundation B.

P = 108' -2x'

P = 108-2x feet

Answer:

36 boards

Step-by-step explanation:

The boards are as long as the room, so I only had to worry about the width. If the boards were 1/2 ft wide, I would need 2 boards for every foot of width. For 16 ft, I would need 32 boards.

Instead of dividing, I wrote the equivalent multiplication by multiplying by the reciprocal of 11/24 (the reciprocal of 11/24 is 24/11)

I simplified by dividing both 2 and 24 by 2, and both 11 and 33 by 11.

Therefore he needs 36 boards

Step-by-step explanation:

Without knowing the specific data of the town, it is impossible to provide an exact probability but we can use the following formula to calculate the probability of an individual being employed full-time, given that they are between 18 and 49 years old:

P(full-time employment | age between 18 and 49) = P(full-time employment and age between 18 and 49) / P(age between 18 and 49)

To calculate this probability, we need to know the number of individuals in the town who are both employed full-time and between the ages of 18 and 49, and divide it by the total population of the town.

P(full-time employment and age between 18 and 49) = Number of individuals employed full-time and between the ages of 18 and 49 / Total population of the town

To calculate this probability, we need to know the number of individuals in the town who are between the ages of 18 and 49, and divide it by the total population of the town.

P(age between 18 and 49) = Number of individuals between the ages of 18 and 49 / Total population of the town

We can use the probabilities calculated in steps 1 and 2 to calculate the probability of an individual being employed full-time, given that they are between the ages of 18 and 49, using the formula:

P(full-time employment | age between 18 and 49) = P(full-time employment and age between 18 and 49) / P(age between 18 and 49)

For example, if there are 10,000 people in the town, and 6,000 of them are between the ages of 18 and 49, and out of those 6,000, 4,000 are employed full-time, then:

P(full-time employment and age between 18 and 49) = 4,000 / 10,000 = 0.4

P(age between 18 and 49) = 6,000 / 10,000 = 0.6

P(full-time employment | age between 18 and 49) = 0.4 / 0.6 = 0.67

Therefore, the probability that an individual is employed full-time, given that they are between the ages of 18 and 49, is 0.67 or 67%.

Answer:

The revised probabilities are;

The probability of finding soil with oil  = 0.8  

The probability of finding soil with good oil = 0.16

The probability of finding medium quality oil =  0.64

Step-by-step explanation:

The given probability of finding soil with high quality oil, P(QO) = 0.20

The probability of finding soil with medium-quality oil, P(OM) = 0.80

The probability of finding soil with no oil, P(ON) = 0.2

Therefore, given that the probability of finding soil with no oil = 0.2, we have;

The probability of finding soil with oil, P(OP) = 1 - the probability of finding soil with no oil

P(OP) = 1 - 0.2 = 0.8

Which gives;

The probability, P(FG) of finding soil with oil and that the oil is good is given as follows;

P(FG) = P(QO) × P(OP) = 0.2 × 0.8 = 0.16

The probability of finding good oil = 0.16

Similarly;

The probability of finding medium quality oil P(FM) =  P(OM) × P(OP) = 0.8 × 0.8 = 0.64

Which gives the revised probability as follows;

The probability of finding soil with oil, P(OP) = 0.8  

The probability of finding soil with good oil, P(FG) = 0.16

The probability of finding medium quality oil, P(FM) =  0.64.                

The area of the triangle is 17/8

In a two-dimensional plane, a triangle's area is the area that it completely encloses. A triangle is a closed shape with three sides and three vertices, as is common knowledge. The entire area occupied by a triangle's three sides is referred to as its area. Half of the product of the triangle's base and height provides the general formula for calculating the area of the triangle.

Let consider this right angled triangle with vertices (0,-4), (0.0), and (1,0).

Its legs have the length 4 and 1; its hypotenuse is  long.

We can easy find the height "h" (the altitude) of this triangle, drawn to hypotenuse.

From the area consideration, we have this equation

(4*1)/2=(1/2)*√17*h

h = 4/√17 = 0.970143.

So, it is not 1 unit, as we see.

It means that the legs of the triangle should be√17/4 as long, as 1 unit and 4 units of the original triangle.

So, the area of the seeking triangle is

(1/2)(√17/4)(√17/4) = (1/2)*(17/4) = 17/8

The area of the triangle under the question is  17/8

In calculus, the limits to infinity degree rules are a set of guidelines used to evaluate limits of functions that approach infinity or negative infinity as the input variable approaches a particular value.

The limits to infinity degree rules can be summarized as follows:

If a polynomial function has the same degree in both the numerator and denominator, then the limit as x approaches infinity (or negative infinity) is equal to the ratio of the leading coefficients.

If the degree of the numerator is less than the degree of the denominator, then the limit as x approaches infinity (or negative infinity) is equal to zero.

If the degree of the numerator is greater than the degree of the denominator, then the limit as x approaches infinity (or negative infinity) is equal to either positive infinity or negative infinity, depending on the signs of the leading coefficients.

However, it is important to note that these rules have limitations and may not always be applicable. For example, they may not apply to functions that involve trigonometric functions or logarithmic functions. In these cases, other techniques such as L'Hopital's rule or algebraic manipulation may be needed to evaluate the limit.

Since, q is the highest common factor, so we'll take q as common

=> q(m+n-p)

This is the required factorized form.

Answer:

q(m+n-p)

Step-by-step explanation:

q is the common factor in all three terms, so take that to go outside the brackets.

What goes inside the brackets depends on the quotient you get upon dividing each term by q.

The graphs of the 3 given functions can be seen in the image attached at the end.

Here we basically want to graph the next 3 functions:

y = x + 3

y = -x + 3

y = |x| + 3

So, the first two are linear equations. To graph these we just need to find two points on the line and connect them with a line.

The last one is the absolute value function translated up by 3 units.

So, to give an example of how to graph the first equation, first we evalaute in x = 0, then we get:

y = 0 + 3 = 3

So we have the point (0, 3)

For that same line we can evaluate in x = 1

y = 1 + 3 = 4

Then we also have the point (1, 4).

Now we have 2 points, we can just connect them with a line.

The graph of the 3 equations can be seen below.
