The equation of the trend line, can be found to be y = - 25 + 250

To find the equation of the trend line, you first need to find the slope. To do this, pick two points on the trend line. ( 4, 150) and ( 8, 50 ).

The slope is:

= ( Y2 - Y1 )/ ( X 2 - X 1 )

= ( 50 - 150 ) / ( 8 - 4 )

= - 100 / 4

= - 25

The equation of the trend line takes the form:

y = mx + b

m = slope

b = y - intercept

The slope allows you to find the y - intercept :

y = mx + b

50 = - 25 ( 8 ) + b

b = 250

The equation is:

y = - 25 + 250

The expected value for each set of 50 items that Sammi sells is $1.82.

The expected value can be calculated by multiplying the profit from each successful sale by the probability of making that sale, and then subtracting the expected cost of each defective item.

Expected value = (Profit from each successful sale * Probability of making that sale) - (Expected cost of each defective item)

Let's assume that Sammi plans to sell 50 items. So, the probability of a successful sale is 49/50 = 0.98. The expected cost of each defective item is $7.

Expected value = ($2 * 0.98) - ($7 * 1/50) = $1.96 - $0.14 = $1.82

So, the expected value for each set of 50 items that Sammi sells is $1.82.

Explanation: You would make sure to include the x since we are unsure of how many apples to bought, we know the total it will be at the other side of the equal sign, she spent 12 on her groceries so we would add that to the number of apples she got.

The particle is at the point (-1.112,3.909) after traveling for 20 microseconds.

We have been given a circle,

(x-3)²+(y-4)²=25

whose center is (3,4)

and with a radius of 5 units.

The particle starts at (3,-1) which is the 6 o'clock position in the circle, and ends at (8,4) after 7 microseconds which are at the 3 o'clock position in the circle.

So, the particle traveled 1/4 of the circumference of the circle in 7 microseconds

therefore according to the unitary method it will travel 5/7 of the circumference of the given circle.

so it will subtend 2π×5/7 of the circle from (3,-1)

from the polar form of the circle and the shifting of center of the circle we can conclude

that it's location will be

(5 × cos (10π/7) - 3 , 5 × sin (10π/7) - 4)

= (-1.112,3.909)

Answer: 30$

Step-by-step explanation:

To find the slope of the equation, you can use the formula (y2-y1)/(x2-x1). Plugging the points the question gives us we can get:

(205-100)/(5-2)

= 105 / 3

= 35

Plugging this information along with a point into the formula y = mx + b:

100 = 35*2 + b

100 = 70 + b

b = 30

y = 35x + 30

To double check this is correct:

y = 35 * 5 + 30

y = 175 + 30

y = 205

(5,205) is a point therefore y = 35x + 30 is the equation

Because the x of the graph represents the number of months, the initial membership fee would be when x = 0.

y = 35*0 + 30

Answer:

because they are not equal in size

The minimum amount of framing Lorraine needs for the square painting is 31 inches.

We can use the Pythagorean theorem to calculate the length of the side of the square given the length of its diagonal. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

We know that the diagonal of the square painting is 44 inches, and since the diagonal of a square bisects its angles, the square can be divided into two congruent right-angled triangles. Therefore, the length of one side of the square can be calculated using the Pythagorean theorem:

44 inches^2 = x^2 + x^2

x^2 = 11*11

x = 11 inches

Since the square painting has a side length of 11 inches, and the framing material is sold by the inch, Lorraine will need a minimum of 11 inches of framing on each side, for a total of 44 inches.

The reflected function is the one below:

g(x) = -√x

This function is represented by the last table.

For a general function y = f(x), we define a reflection over the x-axis as:

g(x) = -f(x)

In this case f(x)=  √x, then the reflected function will be:

g(x) = -f(x) = -√x

Now we can evaluate this function to get some pairs of values.

Then when x = 1

g(1) = -√1 = -1

g(2) = -√2 = -1.41

And so on.

     A variable whose value is decided by a random process or experiment is known as a random variable.

    Depending on how the experiment or random process turns out, it may have a range of distinct numerical values. Random variables come in two varieties: discrete and continuous. A continuous random variable can take on any value within a specific range, such as real numbers, but a discrete random variable can only take on a countable number of values, such as integers.

This random variable has the following distribution and is discrete in nature:

P(X=0) = probability of red or white = P(red) + P(white)

P(X=1) = probability of green or blue = P(green) + P(blue)

P(X=2) = probability of yellow or violet = P(yellow) + P(violet)

P(X=x) must have a sum of all possible values of 1, which indicates that

   P(red) + P(white) + P(green) + P(blue) + P(yellow) + P(violet) = 1

    Therefore ,with a probability  of 1/3 for each value, this random variable has a discontinuous uniform distribution over the set of values 0, 1, and 2.

Answer:

125,664 mm³/s

Step-by-step explanation:

V = (4/3)πr³

dV/dt = (4π/3) × 3r² × dr/dt

dV/dt = 4πr² × dr/dt

dr/dt = 4 mm/s

d = 100 mm; r = 50 mm

dV/dt = 4π(50 mm)² × 4 mm/s

dV/dt = 125,664 mm³/s

By distributive property (5k + 2m)(3p + 4s) this we get   15kp + 20 ks + 6mp +8ms.

It is possible to multiply a single value by two or more values enclosed in a set of parenthesis using the distributive property, an algebraic property.

According to the distributive property, it is necessary to multiply each of the two terms by the factor when adding two terms to a factor. Only then may the addition operation be done. The following is a symbol for this property:

A (B+ C)=AB + AC

When there are three distinct values for A, B, and C.

Example : (5k + 2m)(3p + 4s)

Apply FOIL method:

The energy in the pendulum as it swings from point A to point B

Potential energy is converted to kinetic energy.

Now, According to the question:

Energy is defined as the ability of an object to do work. Energy can be classified in two different types of energy, Kinetic and potential energy. This two may be the principal ones, but we can see how energy manifests in different ways in nature, like heat, chemical potential energy, solar energy, electric potential energy, and so on.

Energy is constantly changing from kinetic to potential energy, and vice-versa in a pendulum. At the lowest point of the pendulum swing, the pendulum will have reach a state of maximum kinetic energy. This due to it attaining the maximum speed the pendulum can reach due to it's movement. As the pendulum start to rise again, it will start to lose kinetic energy and will gain potential energy. This loss in kinetic energy will cause the pendulum to slow down until it reaches it's max height. At this point the pendulum will have converted all of it's kinetic energy to potential energy.

Hence, Potential energy is converted to kinetic energy.

Each person buys a number of cakes

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given, Andy buys x cakes, Betty buys 4 times as many cakes as andy, and colin buys 3 more cakes than andy

So,

Andy has = x Cakes

Betty have = 4x Cakes

Clin has = x +3 Cakes

Since each cake costs 65p and the total cost of the cakes is £52.65

thus,

0.65( x + 4x + x +3) = 52.62

x + 4x + x +3 = 81

6x = 78

x = 13

Therefore,

Andy has = 13 cakes

Betty has = 4x = 4*13 = 52 cakes

Colin has = x + 3 = 16 cakes
