6. 3x - 2y = 19
x + y=8.

Answer:

y - 4 = \(-\frac{3}{2}(x+8)\)

Step-by-step explanation:

Point slope equation of a line passing through (x', y') and slope 'm' is given by,

y - y' = m(x - x')

We have to find the equation of the line which passes through (-8, 4) and slope \((-\frac{3}{2})\),

By substituting these values in the equation,

y - 4 = \(-\frac{3}{2}(x+8)\)

Therefore, point slope form for the given line is,

y - 4 = \(-\frac{3}{2}(x+8)\)

The perimeter of the rectangle is 62 square units.

The perimeter of a rectangle can be calculated using the formula:

P = 2(L + W)

Where:

L is the length of the rectangle

W is the width of the rectangle

We have:

L = 20 units

W = 11 units

Substituting into the formula:

P = 2(20 + 11)

P = 2(31)

P = 62 square units

Question in English

What is the perimeter of a rectangle if it is 20 long and 11 wide?

we should distribute the 133 quintals of wheat among the mills in the following way:

Mill 1: 63.3 centners

Mill 2: 38.4 centners

Mill 3: 75 centners

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, One mill can grind 19 centners of wheat in 3 hours. 32 centners of the second - in 5 hours, and 10 centners of the third - in 2 hours.

Let's first find out the efficiency of each mill, which is the amount of wheat it can grind per hour:

Mill 1:

19 centners / 3 hours = 6.33 centners per hour

Mill 2:

32 centners / 5 hours = 6.4 centners per hour

Mill 3: 1

0 centners / 2 hours = 5 centners per hour

We can see that Mill 2 is the most efficient, followed closely by Mill 1, and Mill 3 is the least efficient.

Let's call the number of hours that each mill will work "x".

The amount of wheat each mill can grind in "x" hours is:

Mill 1: 6.33x centners

Mill 2: 6.4x centners

Mill 3: 5x centners

The LCM of 3, 5, and 2 is 30.

Therefore, if each mill works for 30 / 3 = 10 hours,

30 / 5 = 6 hours,

30 / 2 = 15 hours respectively,

they will all finish at the same time.

The amount of wheat each mill will grind in the allotted time is:

Mill 1: 6.33 x 10 = 63.3 centners

Mill 2: 6.4 x 6 = 38.4 centners

Mill 3: 5 x 15 = 75 centners

This distribution will ensure that all three mills start working at the same time and finish grinding at the same time

Answer:

y = 2x+1

Step-by-step explanation:

The slope-intercept form is given by y = mx + c

where m is the slope, and c is the y-intercept.

Let's apply the point-slope form,

that is: \(\frac{y-y{__1}}{x-x{__1}}} = m\)

Given \(({x__1},{y__1}) = (2,5)\) and \(m = 2\)

Let plug in all these values into the point-slope form.

\(\frac{y-5}{x-2}} = 2\)

y-5 = 2x-4

y = 2x-4+5

y = 2x+1

A percentage can be larger than 100 and a fraction can be greater than 1.

A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it.

A percentage can be larger than 100 and a fraction can be greater than 1. We are limited to looking at the whole only when the fraction or percentage relates to a portion of it.

In addition to being stated as a decimal or a fraction, a percentage is a number that indicates how many out of 100 it is. Three for the price of one! Simply enter the % as the numerator and 100 as the denominator to convert the percentage to a fraction.

Therefore, the correct answer is 35%.

The mean absolute deviation (MAD) for the given data is 1/20. This means that, on average, each data point in the set differs from the mean by 1/20.

To find the mean absolute deviation (MAD) of a set of data, we need to calculate the average difference between each data point and the mean of the data set. Here's how we can calculate it for the given data:

Step 1: Find the mean (average) of the data set.

Mean = (1/4 + 5/8 + 3/8 + 3/4 + 1/2) / 5 = 2/5

Step 2: Calculate the difference between each data point and the mean.

Differences: |1/4 - 2/5|, |5/8 - 2/5|, |3/8 - 2/5|, |3/4 - 2/5|, |1/2 - 2/5|

Step 3: Calculate the absolute value of each difference.

Absolute Differences: 1/20, 1/40, 1/40, 1/20, 1/10

Step 4: Find the average of the absolute differences.

MAD = (1/20 + 1/40 + 1/40 + 1/20 + 1/10) / 5 = 1/20

The MAD provides a measure of the average amount of variation or dispersion in the data set. In this case, a MAD of 1/20 indicates that the data points are relatively close to the mean, with most values falling within 1/20 of the mean value.

Event A and Event B are less likely than rolling the same number both times

What is probability?

The chance of an event can be calculated using the probability formula by simply dividing the favorable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anything between 0 and 1, as the favorable number of outcomes can never exceed the total number of outcomes.

The probability of rolling a 1 on the first roll is 1/6, and the probability of rolling a 2 on the second roll is also 1/6. Therefore, the probability of rolling a 1 on the first roll and a 2 on the second roll is (1/6) x (1/6) = 1/36.

The probability of rolling an even number on the first roll is 3/6 (or 1/2), and the probability of rolling an odd number on the second roll is also 3/6 (or 1/2). Therefore, the probability of rolling an even number on the first roll and an odd number on the second roll is (1/2) x (1/2) = 1/4.

This event is more likely than rolling the same number both times, because there are nine possible outcomes that result in this event (2-1, 2-3, 2-5, 4-1, 4-3, 4-5, 6-1, 6-3, 6-5), while there are only six possible outcomes that result in rolling the same number both times.

Hence, Event A and Event B are less likely than rolling the same number both times

Answer:

f(x) = x³ - 4x + 6

f'(x) = 3x² - 4

a) f'(2) = 3(2²) - 4 = 12 - 4 = 8

6 = 8(2) + b

6 = 16 + b

b = -10

y = 8x - 10

b) 3x² - 4 = 0

3x² = 4, so x = ±2/√3 = ±(2/3)√3

= ±1.1547

f(-(2/3)√3) = 9.0792

f((2/3)√3) = 2.9208

c) 3x² - 4 = 8

3x² = 12

x² = 4, so x = ±2

f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6

6 = -2(8) + b

6 = -16 + b

b = 22

y = 8x + 22

f(2) = 6

y = 8x - 10

The equation perpendicular to the tangent is y = -1/8x + 25/4

-The smallest slope on the curve is 2.92

The curve has the smallest slope at the point (1.15, 2.92)

The equations at tangent points are y = 8x + 16 and  y = 8x - 16

From the question, we have the following parameters that can be used in our computation:

y = x³ - 4x + 6

Differentiate

So, we have

f'(x) = 3x² - 4

The point is (2, 6)

So, we have

f'(2) = 3(2)² - 4

f'(2) = 8

The slope of the perpendicular line is

Slope = -1/8

So, we have

y = -1/8(x - 2) + 6

y = -1/8x + 25/4

We have

f'(x) = 3x² - 4

Set to 0

3x² - 4 = 0

Solve for x

x = √[4/3]

x = 1.15

So, we have

Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6

Smallest slope = 2.92

So, the smallest slope is 2.92 at (1.15, 2.92)

Here, we set f'(x) to 8

3x² - 4 = 8

Solve for x

x = ±2

Calculate y at x = ±2

y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

y = (2)³ - 4(2) + 6 = 6: (2, 0)

The equations at these points are

y = 8x + 16

y = 8x - 16

A perpendicular ZO is drawn from Z to the side XW.

The triangle ZOW is an right angled triangle

having base OW , perpendicular OZ = 18 and hypotenous ZW = 23.2

base² = hypotenous² - perpendicular²

OW² = ZW² - OZ²

OW² = 23.2² - 18²

OW² = 538.24 - 324

OW= √214.24

OW = 14.6

Area of the triangle = 1/2 base x height

= 1/2 x 14.6 x 18

Area of trapezium YXOZ = 1/2 x base x sum of parallel sides
