The delivered price (including freight) of the living room set is $2858.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

List Price = $5800

Trade  discount = 50%

So, Price after discount

= $5800 - 50% x $5800

= 5800- 2900

= $2900

if Levin pays within 10 days he will have a discount of 3%, So,

3% x $2900

= $87

Thus, the Delivered price = $2900 -$87+ freight charges ( shipping)

                                           = $2900 -$87 + $45 =$2858

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

NUMBER 25

x = 53° (alternate angles)

x + y + 49° = 180° (sum of angles in a triangle is 180°)

The mass of the sample after four days is 1.75 kg.

The decay rate for a radioactive substance follows the exponential decay formula:

m(t) = m₀ * e^(-kt),

where m₀ is the initial mass, m(t) is the mass at time t, k is the decay rate parameter, and e is the base of the natural logarithm.

Given that the initial mass of the sample is 2.05 kg and the decay rate parameter is 4% per day, the formula becomes:

m(t) = 2.05 * e^(-0.04t).

To find the mass after four days, we substitute t = 4:

In my opinion it is the answer .

Thankyou .........!

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.

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 coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5). The solution has been obtained by using the concept of reflection.

What is reflection?

In geometry, a reflection is referred to as a flip. In a reflection, the shape is reflected. An image will reflect over a line known as the line of reflection.

We are given a point T(-2, 5)

In order to find the coordinates of the reflection of  point in the y-axis, we need to change the sign of abscissa i.e., x-coordinate and retain the ordinate i.e., y-coordinate.

So, we get the image of (-2 , 5) as (2, 5)

Thus, the coordinates of point T' after Ry-axis is (2, 5).

When we reflect across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

So, we get the image of (-2 , 5) as (-2, -5).

Thus, the coordinates of point T' after Rx-axis is (-2, -5).

Hence, the coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5).

the value of ∠A is 59 degrees and  the value of ∠B is 48 degrees.

We know that from angle sum property the sum of three angles is 180 degrees.

∠A+∠B+∠C=180

59+48+∠C=180

107+∠C=180

The probability that at least one of the codes will have repeating digits is 0.4712.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here, The probability of a pin being repeated is 14.7%

⇒ 14.7/100

After Eliminating the decimal point;

⇒ 14.7/100 = 147/1000

Hence,

The probability that a pin, if selected will have a repeating digit format = 147/1000

The probability of a pin not having repeating digits format is,

⇒ 1 - 147/1000

⇒ 853/1000

If four codes are selected at random (without replacement), the probability that all four of the codes will not have repeating digits format is,

⇒ (853/1000) x (852/999) x (851/998) x (850/997)

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.

The first step in obtaining the number of solutions of the system of equations is obtaining the linear function that represents each line.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

m is the slope.

b is the y-intercept.

here, we have,

The first line goes through these following points:

(0,3) and (3,4).

The slope is given by change in y divided by change in x, hence:

slope = 3

When x = 0, y = 3,

hence the intercept is of b = 3

and the function is given as follows:

y = 3x - 3

The second line goes through these following points:

(0,-2) and (3,-1).

Hence the slope is of:

m = 3

The intercept is of b = -2,
