In 27 minutes, Daquin completed 30% of his schoolwork. He must therefore finish another 70% of her homework.

We must multiply both sides of the equation by 3 to see how long it takes Daquin to finish 10% of the homework. It takes her 9 minutes.

We simply need to multiply our time estimate by seven to determine how long it will take her to complete the remaining 70% of her homework.

9 minutes are required for 10% of the homework.

63 minutes are required to complete 70% of the homework.

% finished equals 30%

Duration: 27 minutes

70% of the homework is still to be done.

Time required for the remaining task is 70/30 divided by 27 is equal to 63 minutes.

The function rule in slope-intercept form is y = -4x - 2

Mathematically, the slope-intercept form of a straight line can be calculated by using this equation:

y = mx + c

Where:

From the graph of this line, we have the following data points:

Point (x, y) = (-1, 2)

Point (x, y) = (0, -2)

In Mathematics, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (-2 - 2)/(1 - 0)

Slope, m = -4/-1

Slope, m = -4

Note: The y-intercept occurs at the point where the x-value is equal to zero (0).

Now, we can write the function rule for this line in slope-intercept form as follows:

y = mx + c

y = -4x - 2

The length and width of a rectangle that maximises the enclosed area are 162.5 yards. The maximum area is 26,406.25 square yards.

In the given question we have to find the maximum area of the rectangular area.

A farmer with 650 meters of fencing wants to enclose a rectangle plot that border on a river.

As we know that the perimeter of rectangle

P= 2(l+b)

Let length of the rectangle is x yards and width is y yards.

So the equation should be

2(x+y) = 650

Divide by 2 on both side we get

x+y = 325................(1)

From the area of rectangle is

A = xy

From the equation the value of y is 325-x.

Now putting the value of y

A = x(325-x)

A = 325x-x^2

On differentiating

dA/dx = 325-2x

Putting dA/dx=0

325-2x=0

Subtract 325 on both side we get

-2x= -325

Divide by -2 on both side we get

x = 162.5 yards

Now putting the value of x in the y=325-x

y=325-162.5

y=162.5 yards

So the maximum area is

A= 162.5*162.5

A= 26,406.25 square yards

Hence, the length and width of a rectangle that maximises the enclosed area are 162.5 yards. 26,406.25 square yards is the maximum area.

Step-by-step explanation:

The probability that a household in Maryland has an annual income of 100000 or more is 0.2373

Given Data;

Maryland had the greatest mean yearly household income of any state, according to Money magazine (time website). Consider a normal distribution with a mean of 75847 and a standard deviation of 33800 for the annual household income in Maryland.

Population Mean (μ) = 75847

Population Standard Deviation (σ) = 33800

'X' follows a normal distribution with a population mean and population standard deviation.

Here,

X ~ N ( μ = 75847 ,σ = 33800 )

Z =(X - μ)/σ

To get the probability that a household in Maryland has an annual income of 100000 or more.

Now, we have to compute P (X > 100000)

P (X > 100000) = 1 - P( (X-μ)/σ < (100000-75847)/33800 )

                         = 1 - p(z < 0.715 )

                         = 1 - 0.7627

                         = 0.2373

The frequency of data value 1 that is 10 will be 6 as "Dividing each frequency by the total number of data values gives the relative frequency. So multiplying the relative frequency by the total number of data values gives the frequency."

The proportion of outcomes where a specific event occurs to all trials, not in a hypothetical sample space but in a real experiment, is known as the empirical probability, relative frequency, or experimental probability of an event. The relative frequency is calculated by dividing each frequency by the total number of data values. Therefore, the frequency is calculated by multiplying the relative frequency by the total number of data values.

Here,

Value                                           Relative frequency

10                                                  0.15

20                                                 0.30      

30                                                 0.45

40                                                 0.10

data 1 value=10

Dividing each frequency by the total number of data values gives the relative frequency.

So, multiplying the relative frequency by the total number of data values gives the frequency.

40*0.15=6

Since "multiplying the relative frequency by the total number of data values gives the frequency," the frequency of the data value 1 that is 10 will be 6.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The first equation is,

y = - 2x + 4

And, A line goes through (0, 4) and (2, 0).

Now,

For the second linear equation;

The coordinates are,

(-4, -3) (0, -1) , (2, 0) , (6, 2)

Hence, The equation of line passes through the points (-4, -3) and (0, -1).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 1 - (-3)) / (0 - (-4))

m = 2 / 4

m = 1/2

Thus, The equation of line with slope 1/2 is,

⇒ y - (-3)= 1/2 (x - (-4))

⇒ y + 3 = 1/2 (x + 4)

⇒ y = 1/2x + 2 - 3

⇒ y = 1/2x - 1

Now, We find the value of system of equations;

y = - 2x + 4

y = 1/2x - 1

Solve both above equation, we get;

1/2x - 1 = - 2x + 4

1/2x + 2x = 4 + 1

5/2x = 5

x = 2

And, y = 1/2 (2) - 1 = 0

Thus, The solution to the system of equations will be;

Yes, there is causation between the two given variables, as the weight is related at some point with the amount of calories consumed.

For two variables x and y, we say that there is causation when, if we modify one of the variables, the other changes in response.

Correlation just means that the variables are related in some way (maybe both have a causation relationship with the same other variable)

So causation implies correlation.

Correlation does not imply causation.

In this case, we have the example:

x = The number of additional calories consumed

y =  amount of weight gained.

Clearly, we have causation between x and y as larger is the value of x, larger will be the value of x.-

The distance between the anchor points of the two guy wires holding radio antenna is 181 feet (to the nearest foot)

The problem will be solved using SOH CAH TOA

let the distance between the 150 ft long guy wire and the radio antenna be x

let the distance between the 180 ft long guy wire and the radio antenna be y

cos 65° = x / 150

x = cos 65° * 150

x = 63.39 ft

The height of the antenna

sin 65° = height of antenna / 150

height of antenna = sin 65 * 150

height of antenna = 135.95

using Pythagoras theorem

(length of guy wire)² = (height of the antenna)² + (anchor distance)²

(anchor distance)² = 180² - 135.95²

anchor distance = √(180² - 135.95²)

anchor distance = 117.97

The anchor points distance apart

= 63.39 + 117.97

= 181 (to the nearest foot)

x calories = 1 pound

Recall, 1 pound = 16 ounces

504 calories : 8 ounces = x calories : 16 ounces

504 / 8 = x / 16

Cross Multiply

504 * 16 = 8 * x

8,064 = 8x

Step-by-step explanation:
Here is an example:
Use this step by step explanation in your equation to help you find the answer.
For polynomial 2x2 - 3x5 + 5x6.

We observe that the above polynomial has three terms. Here the first term is 2x2, the second term is -3x5 and the third term is 5x6.

Now we will determine the exponent of each term.

(i) the exponent of the first term 2x2 = 2

(ii) the exponent of the second term 3x5 = 5

(iii) the exponent of the third term 5x6 = 6

Since, the greatest exponent is 6, the degree of 2x2 - 3x5 + 5x6 is also 6.

Therefore, the degree of the polynomial 2x2 - 3x5 + 5x6 = 6.
