The m∠ABC is 17°. The solution is obtained using the concept of inscribed angle.

Two chords with a shared termination point on the circle make up an inscribed angle in a circle. The vertex of the angle is this common terminal point. In other words, an angle is said to be inscribed if its vertex is on a circle and both of its sides are chords of the same circle.

An inscribed angle's measurement is equal to half of an intercepted arc's measurement.

It is shown in the figure that length of the arc is 34°.

We are given that ∠ABC is an inscribed angle.

We know that an inscribed angle is half of the arc it comprises.

So, m∠ABC= 34/2

= 17°

Hence, the m∠ABC is 17° .

Answer: just make a guess because we do not do that here sorry can i help u with something diffrent

Step-by-step explanation:

The required measure of ∠DEB = 26° for the given figure.

An angle bisector is defined as a line that divides an angle into two equal angles.

If EF bisects angle ∠CEB,

angle ∠CEF=7x + 21 and angle ∠FEB = 10x-3

As per the given figure, we can write the equation as:

7x + 21 =  10x - 3

Combine the likewise terms,

10x - 7x = 21 + 3

3x = 24

x = 24/3

x = 8

Substitute the value of x = 8 in the ∠CEF = 7x + 21

So ∠CEF = 7(8) + 21 = 77°

Substitute the value of x = 8 in the ∠FEB = 10x-3

So ∠FEB = 10(8)-3 = 77°

So ∠AEC = 180° - 77° - 77° = 26°

So ∠DEB = ∠AEC = 26°

The dependent variable is the total cost of leasing the car while the independent variable is the number of months that the car is leased.

We know that when we talk about the independent variable, we have to look at the variable that changes and as this variable changing, there would be a change in another variable.

In the case that we have here, we can see that as the number of months is changing, so does the total cost. As such, the total cost would be the dependent variable while the number months would be the independent variable.

The surface area of the cone with a diameter 8in and slant height 6in is 125.6 in²

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The surface area of a cone is expressed as;

A = πrl + πr²

Where r is radius and l is slant height.

Plug the given values into the equation  above.

A = πrl + πr²

A = ( 3.14 × 4 × 6 ) + ( 3.14 × (4)² )

A = ( 3.14 × 4 × 6 ) + ( 3.14 × 16 )

A = 75.36 + 50.24

A = 125.6 in²

Therefore, the area is 125.6 in².

The fraction of the total amount of ingredients that is neither fruit nor yogurt is 0.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

The total fraction of all the ingredients are given as follows:

100% = 1.

The ingredients, along with their fractions, are given as follows:

Fruits: 2/3.

Yogurt: half of fruit = 2/3 x 1/2 = 2/6 = 1/3.

So the percentage contained fruit or yogurt is given as follows:

2/3 + 1/3 = 3/3 = 1 = 100%.

There are only two components in the recipe, fruit, and yogurt, so the amount of ingredients that is neither fruit nor yogurt is 0.

Answer:

x=92

Step-by-step explanation:

a triangle is 180 degrees

the angle vertical to the 32 degree angle is also 32

so knowing all the information 180-32-60= 88, but remember that 88 is a supplementary angle to x, meaning the two angles add up to 180, so 180-88=92 degrees

In Massachusetts, it has rained 60% of the time on days with identical conditions as this day.

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

Probability is the likelihood that an event will occur.

Given that, there is a 60% chance that it will rain on a particular day.

As a result, 60% of the time on that day it rained.

Therefore, the correct answer is option D. On days with similar conditions as this day, it has rained 60% of the time in Boston, Massachusetts.

There is a 7/32 chance of getting exactly 6 heads. Events must be independent of one another and have a probability sum of one in order to be used in the probability.

The basis for the binomial distribution is the binomial theorem, which is expressed as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ. Events must be independent of one another and have a probability sum of one in order to be used in the probability. A fair coin is tossed eight times, according to the rule. Half the time, you'll receive the head. Moreover, there is a 50% chance of receiving a tail.

The expression of the binomial distribution, [tex]${ }^n C_x p^x q^{n-x}$[/tex], can be used to solve the preceding problem, where n is the total number of trials, x is the favorable number of trials, and p and q are the probabilities of success and failure, respectively. The binomial distribution can be used to calculate the likelihood of receiving a tail 7 times out of 8.

As a result, the likelihood of receiving exactly 6 heads is 1/32.

[tex]$\begin{aligned} \mathrm{P}(\text { exact } 6 \text { heads }) & ={ }^8 \mathrm{C}_6(1 / 2)^6(1 / 2)^1 \\ & =28 \times 1 / 64 \times 1 / 2 \\ & =7 / 32\end{aligned}$[/tex]

As a result, the likelihood of receiving exactly 6 heads is 1/32.

A graph of a function intersects the x-axis at the point (x,0).

If the equation has no real-number solutions, what is the discriminant?

A positive discriminant suggests that there are two unique real number solutions to the quadratic. When the discriminant is 0, the quadratic has a repeating real number solution. A negative discriminant means that neither solution is a real number.

Because the discriminant is smaller than zero, the equation has no valid solutions.A is the correct answer. The function’s graph does not cross the x-axis at all. If the discriminant is larger than zero, the equation has two separate and real roots. The equation will have a real root if the discriminant is zero. If the discriminant is smaller than zero, the equation has no real roots and only two complex roots.

The relation shown in the table is not a function.

A function is a process or set of instructions that takes inputs, performs a specific task, and produces an output. Functions are key components of programming languages, allowing the coder to create complex commands with simple instructions. For example, a function can be used to add two numbers together or to generate a random number. Functions can also be combined to create more complex sequences of instructions.

This is because for the input of x = 9, there are two corresponding outputs of y, namely 6 and 4. This does not satisfy the definition of a function, which states that for any given input, there must be only one output. Therefore, the relation shown in the table is not a function.

The system of equations that can be used to determine the number of weeks it will take for Jerimiah and Darren to collect the same number of cards is option A: y = 3x + 11 and y = 4x + 5.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The number of baseball cards Jerimiah collected = 11

The number of baseball cards Darren collected = 5

The number of baseball cards Jerimiah collected every week = 3

The number of baseball cards Darren collected every week = 4

Let the value of number of weeks be x.

The number of cards collected by Jerimiah and Darren is y.

So, the equation for Jerimiah will be -

Number of cards = 3 (number of cards) + 11

Similarly, the equation for Darren will be -

Number of cards = 4 (number of cards) + 5

So, the two equations are -

y = 3x + 11

y = 4x + 5

Now, if the number of week is 6, substitute x = 6 in both the equations -

y = 3(6) + 11

y = 18 + 11

y = 29

y = 4(6) + 5

y = 24 + 5

y = 29

Therefore, it will take 6 weeks for Jerimiah and Darren to collect same number of cards.

The temperature of City A and City B on that day was 4°C and 3°C respectively.

The correct answer choice is option B

Let

The temperature of City A = x

The temperature of City B = y

4x = 7 + 3y

x − 3y = −5

From equation (2)

x = -5 + 3y

Substitute into equation (1)

4x = 7 + 3y

4(-5 + 3y) = 7 + 3y

-20 + 12y = 7 + 3y

12y - 3y = 7 + 20

9y = 27

divide both sides by 9

y = 27/9

y = 3

Substitute into (1)

4x = 7 + 3y

4x = 7 + 3(3)

4x = 7 + 9

4x = 16

divide both sides by 4

x = 16/4

x = 4

Hence, City A was 4° C, and City B was 3° C on that day.
