Answer:

I don't know if its right, but here's what I find.

The table represents a linear function because the rate of change is constant or all the points lie on a straight line.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables

From the given table it is noticed that the line passes through points (-1, -2), (0, 0), (1. 2), and (2, 4).

The slope of the line is

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

The slope of the line is. It means the value of y increased by 5 if the value of x increased by 2.

From the given points we can notice that the value of y increased by 5 if the value of x increased by 2. So, the function has the same slope for any two points.

Since the rate of change (slope) is the same for all points, therefore the table represents a linear function.

Therefore, If we plot these points on a coordinate plane and connect then we get a straight line. I mean it is a  linear function.

Answer:

Step-by-step explanation: We can solve it by doing a cross multiplication, basically finding the X, which is how much he'd pay for 10 pounds:

24 ------- 4

x ---------- 10

You can read this as "if 24 dollars is 4 pounds, how many dollars is 10?"

Anyways, so we multiply on a "X" shape, like this:

4x = 24 x 10

The equation will look better if you multiply the X first.

CONTINUING:

4x = 24 x 10

4x = 240

x = 240/4

x = 60

Therefore, Jackson would pay 60 dollars for 10 pounds of apples.

We could also do this by finding out first how many pounds of apples you can get with 1 dollar, we would do the same thing as before, but now looking for the pounds, not the dollars:

24 ------- 4

1 --------- X

24x = 4

x= 4/24

x= 0,166

So you can buy 0,16 pounds of apples with 1 dollar, so if we want to find out how much we can buy with 24 dollars we multiply 0,166 by 24, which is 3,984, approximately 4 pounds.

But since working with small numbers is quite odd sometimes, I recommend you do this equation with the first method I mentioned.

Option B. N=24; 1%-3.6; PV = ; PMT=-415; FV=0; P/Y=12; C/Y=12; PMT:END

Step-by-step explanation:

The TVM (Time Value of Money) Solver on a graphing calculator is used to calculate the present value (PV) of an investment. The input values for the solver include the number of periods (N), the interest rate (I%), the present value (PV), the payment (PMT), the future value (FV), the payment frequency per year (P/Y), and the compounding frequency per year (C/Y). In this case, the expression ($415)((1+0.003)24 - 1) is equivalent to the future value of an investment that receives a payment of $415 every period for 24 periods, with an interest rate of 0.3% per period. By plugging in N=24, I%=3.6, PV=0, PMT=-415, FV=0, P/Y=12, and C/Y=12 into the TVM Solver with PMT as the payment type, the same value for PV will be returned as the expression ($415)((1+0.003)24 - 1).

(ii) The tanker supplied 155.51 m³ of water in all

The volume of a cylinder can be calculated using the formula:

V = πr²h

where r and h are the radius and height of the cylinder

Thus, volume of tanker = π * 1² *70 = 70π m³

The volume of a cuboid can be calculated using the formula:

V = Length (L) × Width (W) × Height (W)

volume of cuboidal water tank = 7 * 2 * 3 = 42m³

The volume of sphere can be calculated using the formula:

V = 4/3 πr³

where is the radius of the sphere

r = 42/2 = 21 cm = 0.21 m

volume of spherical clay pots = 4/3 * π * 0.21³ = 0.012348π cm³

(i) Number of colonies = Volume of tanker/Volume of cuboidal tank

Number of colonies = 70π/42 = 5 colonies

(ii) Quantity of water = (3 * Volume of cuboidal tank) + (400 * volume of matkas)

Quantity of water = (3 * 42) + (400 * 0.012348π)

From the result that we have here the total number of grey wolves is given as 32

To estimate the population of the grey wolves in the Northern Rockies, we need to find the average number of tagged grey wolves in each sample of 20 and use that as a estimate for the population.

The mean number of tagged wolves in the five samples is:

(1 + 2 + 2 + 1 + 2) / 5 = 8 / 5 = 1.6

This means that, on average, 1.6 wolves out of 20 have a tag. We can use this information to estimate the total population of the grey wolves in the Northern Rockies:

(1.6 tagged wolves per sample of 20) * (total number of grey wolves / 20) = total number of tagged grey wolves

Multiplying both sides of the equation by 20, we find:

total number of grey wolves = (1.6 tagged wolves per sample of 20) * 20 = 32 grey wolves

So, we estimate that there are approximately 32 grey wolves in the Northern Rockies.

The solutions are given below:-

Part (a),

X₁ + X₂ have distribution Bi(n₁+n₂, p)

Part (b),

P(X ₁+ X₂ = 1 | X₂ = 0) =  np(1-p)ⁿ¹⁻¹

P(X₁+X₂ = 1| X₂ = 1) = (1-p)ⁿ¹

P(X₁ + X₂ = 1) = (1-p)ⁿ¹ * np(1-p)ⁿ²⁻¹+ (1-p)ⁿ²*np(1-p)ⁿ¹-¹

Since both variables are independent but they have the same probability parameter, you can interpret that as if the experiment that models each try in both variables is the same.

When you sum both random variables together, what you obtain as a result is the total amount of success in n₁+n₂ tries of the same experiment, thus X₁+X₂have distribution Bi(n₁ + n₂, p).

b)

Note that, if X₂ = k, then X₁ +X₂ = 1 is equivalent to X₁ = 1-k. Since X1 and X₂ are independent, then P(X₁ +X₂ = 1| X₂ = K) = P(X1=1-k|X₂=k) = P(X₁ = 1-k).

If k = 0, then this probability is equal to P(X₁ = 1) = np(1-p)ⁿ¹⁻¹

If k = 1, then it is equal to P(X₁ = 0) = (1-p)ⁿ¹

Thus,

P(X₁+X₂ = 1) = P(X₁+X₂ = 1| X₂ = 1) * P(X₂=1) + P(X₁+X₂ = 1| X₂ = 0) * P(X₂ = 0) = (1-p)ⁿ¹ * np(1-p)ⁿ²⁻¹+ (1-p)ⁿ²*np(1-p)ⁿ¹-¹.

The equation that represents the given graph is: D. y = 2/5x - 3.

The slope-intercept form of the equation of a line is given by y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of a line that passes through two points (x1, y1) and (x2, y2), we can use the following steps:

So, for the line that passes through the points (0, -3) and (5, -1), the slope is (-1 - (-3)) / (5 - 0) = 2/5, and the y-intercept can be found by plugging in the slope and the point (0, -3) into the equation y = mx + b:

-3 = (2/5) * 0 + b

-3 = b

Therefore, the equation of the line that passes through (0, -3) and (5, -1) is:

Two lines have equal slopes if they are parallel to one another. In other words, both equations have an identical ratio of the x and y coefficients.

For any real value of k, the equation for the line perpendicular to the line axe + by + c = 0 is given by axe + by + k = 0.

Thus, a line parallel to the line 9x + 8y - k = 0 has the equation 9x + 8y + k = 0.

We know that this line intersects at (-8, 7), thus 9(- 8) + 8(7) + k = 0 k= -16 Rightarrow

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

To solve the problem it is important to raise equations regarding what happens.

They tell us that Billy (Bi) and Bobby (Bo) can mow the lawn in 60 minutes. That is to say that what they prune in a minute is giving as follows:

1 / Bo + 1 / Bi = 1/60 (1)

They say Billy could mow the lawn only in 20 minutes less than it would take Bobby, therefore

1 / Bi = 1 / (Bo-20) (2)

Replacing (2) in (1) we have:

1 / Bo + 1 / (Bo-20) = 1/60

Resolving

(Bo - 20 + B0) / (Bo * (Bo-20) = 1/60

120 * Bo - 1200 = Bo ^ 2 - 20Bo

Rearranging:

Bo ^ 2 - 140Bo -1200 = 0

Now applying the general equation

Bo = 130.82 or Bo = 9.17, this last value cannot be because Billy took 20 minutes less and neither can he prune faster than the two together, therefore Bobby only takes around 131 minutes and Billy around 111 minutes
