The measure angle EBF is (5b-24)°.

Adjacent angles are those angles that are always placed next to each other in such a way that they share a common vertex and a common side but they do not overlap each other.

Give that, m∠ABF =(7b-24)° and m∠ABE =2b°.

From the figure,

m∠ABF =m∠ABE + m∠EBF

(7b-24)°=2b° + m∠EBF

m∠EBF = 7b-24-2b

m∠EBF = (5b-24)°

Therefore, the measure angle EBF is (5b-24)°.

The secant-tangent rule which is a relationship between a secant and a tangent of a circle indicates that we have;

(a) [tex]\overline{BC}[/tex]² = [tex]\overline{CD}[/tex] × [tex]\overline{CF}[/tex]

(b) The length of the tangent [tex]\overline{BC}[/tex], found based on the secant-tangent rule is 12 inches

A tangent to a curve at a point is the line that touches the curve at the specified point and has the same slope as the curve at the point.

(a) The relationship between the lengths of the segments formed by the secant and the tangent is indicated by the secant-tangent rule which can be presented as follows;

[tex]\overline{BC}[/tex]² = [tex]\overline{CD}[/tex] × [tex]\overline{CF}[/tex]

Therefore, the relationship between the segments is that the square of the length of the tangent is equivalent to the product of the length of the secant and the external segment of the secant

(b) Where the length of the secant (segment) [tex]\overline{CD}[/tex] = 16 inches, and the length of the external segment of the secant, [tex]\overline{CF}[/tex] = 9 inches, therefore, according to the secant-tangent rule, we get;

[tex]\overline{BC}[/tex]² = 16 × 9 = 144

[tex]\overline{BC}[/tex] = √(144) = 12

The volume of the solid is 16.75 unit³ in the given line x+2y=8 intercseting the x-axis, the y-axis.

What is volumes of Solids?

We shall encounter several solids and their corresponding volumes when discussing the concept of the volume of combination of solids. As is common knowledge, the surface areas and volumes of all three-dimensional shapes depend on their dimensions. As we can see in reality, numerous shapes are created by fusing a variety of shapes. For instance, the combination of a cone and cylinder shapes creates a tent. Similar to how a cone and a hemisphere combine to form an ice cream cone. As a result, the volume of the solids combined will equal the total of the volumes of the individual solids.

The line  x+2y=8.

y = (8-x)/2

Volume will be V = π/2 ∫(r²) dr

So we have 1/3 π * r² * h

Here h = 8, r=2.

So V = 1/3 π * r² * h = 1/3 π * 2² * 8

V = 16.75 unit³

Hence ,the volume of the solid is 16.75 unit³

No, blinding was not demonstrated in the experiment because the volunteers knew whether they are drinking purple juice or yellow juice.

Blinding is the process of hiding a participant's group assignment from one or more other participants in a clinical research study, most frequently a randomized controlled trial (RCT).

Although the candy has the same flavour as the drink, participants can tell the difference based on colour. No, because the participants are aware of whether they are consuming yellow or purple juice.

To create a yellow or pink candy, two separate additives that don't affect flavour are added to identical sweets.

In each experiment, group allocations are concealed from data analyzers by blinding or masking. This experiment is not a blinding demonstration since the subject is aware of the juice.

As a result, adolescent volunteers are at random allocated either pink candy or yellow candy, both of whom are aware of the juice.

Answer:

Step-by-step explanation:

Let's assume that the total amount spent on the movie tickets and snacks is represented by x.

We know that:

The movie ticket costs $13.00

The drinks cost $6.00

Therefore, the equation representing the total amount spent is:

x = 13 + 6 + 4y

where y is the number of snacks purchased.

Let's substitute the given value of x:

23 = 13 + 6 + 4y

Subtracting 13 and 6 from both sides:

4 = 4y

Dividing both sides by 4:

y = 1

So, you purchased 1 snack.

A z-score of -2 means that the income of $40,000 is 2 standard deviations below the mean income of $64,000.

The z-score is a standard measure of how many standard deviations a data point is away from the mean. To determine the z-score, we need to use the formula:

z = (x - μ) / σ

Where x is the data point of interest ($40,000), μ is the mean ($64,000), and σ is the standard deviation ($12,000).

Substituting the values:

z = (40000 - 64000) / 12000

z = -2

Therefore, the z-score for someone with an income of $40,000 is -2.

In conclusion, a z-score of -2 means that the income of $40,000 is 2 standard deviations below the mean income of $64,000.

The population will be 40 thousnd after 22.5 years,and 60 thousand after 34.4 years.

First, we want to estimate the number of years that takes to reach 40 thousand, to estimate that we need to look at the graph.

We can see that when y = 40, the value of x is between 20 and 25 (almost in the middle)

So here we estimate that the answer is 22.5

b) Now we want to estimate it using the equation

p(x) = 18*e^(0.035*x)

We want to find how many years it takes to reach a population of 60 thousand, then we need to solve:

p(x) = 18*e^(0.035*x) = 60

        e^(0.035*x) = 60/18

Using the natural logarithm in both sides:

ln( e^(0.035*x))  = ln(60/18)

0.035*x =  ln(60/18)

x =  ln(60/18)/0.035 = 34.4

The total square footage (area) of the apartment is 385 square feet.

The total square footage, also known as the area, of an apartment is a measure of how much space the apartment has.

First, let's find the area of the 11ft by 11ft bedroom. To do this, we multiply the length and the width of the room. In mathematical terms, the area of a rectangle is equal to the length times the width. So, for the bedroom, the area is

=> 11ft * 11ft = 121 square feet.

Next, let's find the area of the 4ft by 6ft bathroom. The formula for the area of a rectangle is still the same, so the area of the bathroom is

=> 4ft * 6ft = 24 square feet.

Finally, we'll find the area of the multi-use living room/kitchen, which is 15ft by 16ft. The area of this room is

=> 15ft * 16ft = 240 square feet.

Now that we have the area of each room, we can add them together to find the total area of the apartment. So, the total area is

=> 121 square feet + 24 square feet + 240 square feet = 385 square feet.
