Answer:

144

Step-by-step explanation:

Exterior angle = [tex]\frac{360}{number \ of \ sides}[/tex]

                       [tex]=\frac{360}{10}[/tex]

                       = 36

Interior angle and exterior angles are supplementary.

interior angle + exterior angle = 180

Interior angle + 36 = 180

Interior angle = 180 - 36

                       = 144

Answer:

A) 89 personas prefieren ver sólo deportes.

B) 122 personas prefieren ver sólo un programa de televisión

C) 33 personas prefieren ver películas o musicales.

Step-by-step explanation:

Dado que una empresa realizó una encuesta a 250 personas para saber qué programa de televisión prefieren ver en domingo, y se les dieron 3 opciones: deportes, películas o musicales, donde el resultado de la encuesta fue: 130 personas prefieren deportes; 80 prefieren ver películas; 40, musicales; 25 prefieren deportes y películas; 20, películas y musicales; 10, deportes y musicales; y sólo a 6 personas les gustan los tres tipos de programas; para determinar A) cuántas prefieren ver sólo deportes, B) cuántas prefieren ver sólo un programa de televisión; y C) cuántas prefieren ver películas o musicales, se deben realizar los siguientes cálculos:

A)

130 - 25 - 10 - 6 = 89

B)

80 - 25 - 20 - 6 = 29

40 - 20 - 10 - 6 = 4

89 + 29 + 4 = 122

C)

29 + 4 = 33

Answer:

[tex]P(B|A)=\frac{2}{7}[/tex]

Step-by-step explanation:

The probability of [tex]P(B|A)[/tex] can be read as the probability of event B occurring given event A. In this question, event A occurs when the chosen player is a girl. There are 7 girls on the soccer team. Event B occurs when the chose player plays defense. Since [tex]P(B|A)[/tex] stipulates that event A already occurred, we want the probability of choosing a player who prefers defense from the 7 girls. There are 2 girls who prefer defense, hence [tex]P(B|A)=\boxed{\frac{2}{7}}[/tex].

Alternative:

For dependent events [tex]A[/tex] and [tex]B[/tex], the conditional probability of event B occurring given A is given by:

[tex]P(B|A)=P(B\cap A)\div P(A)[/tex]

[tex]P(B\cap A)[/tex] indicates the intersection of [tex]P(B)[/tex] and [tex]P(A)[/tex]. In this case, it is the probability that both events occur. Since there are 16 kids on the soccer team and only 2 are girls and prefer defense, [tex]P(B\cap A)=\frac{2}{16}=\frac{1}{8}[/tex]. The probability of event A occurring (chosen player is a girl) is equal to the number of girls (7) divided by the number of kids on the team (16), hence [tex]P(A)=\frac{7}{16}[/tex].

Therefore, the probability of event B occurring, given event A occurred, is equal to:

[tex]P(B|A)=\frac{1}{8}\div \frac{7}{16},\\\\P(B|A)=\frac{1}{8}\cdot \frac{16}{7}=\boxed{\frac{2}{7}}[/tex]

Answer:

One solution

Step-by-step explanation:

Hi there!

We are given this system of equations:

5x+6y=1

-5x-8y=2

And we want to see how many solutions the equation has.

Let's solve the system in order to see how many solutions it has

Let's solve this system by elimination, where we will clear one variable by adding or subtracting the equations, solve for the other variable which wasn't cleared, and then use the value of the un-cleared variable to find the value of the variable we cleared earlier.

In order to clear a variable, the coefficients in front of those variables need to be opposites of each other (ex. if we wanted to clear y, the coefficients in front of y need to be -2 and 2 respectively). In this case, the coefficients in front of x are 5 and -5, so we can immediately add the equations

Add both equations together

-2y=3

Divide both sides by -2

y=-3/2

Now substitute -3/2 as y in either one of the equations to solve for x

If we were to do it in 5x+6y=1 for instance:

5x+6(-3/2)=1

multiply

5x-9=1

add 9 to both sides

5x=10

divide both sides by 5

x=2

So we solved the system and got x=2, y=-3/2 (or as a point, (2, -3/2)). This is the point of intersection of the two equations (in case you didn't notice, the equations are actually linear equations written in standard form). This is the ONLY point at which the lines will intersect.

Therefore, the system has one solution.

Hope this helps!

The difference between  CDs sold between 1993 and 2001 will be 76.7 × 10⁵.

To subtract in mathematics is to take something away from a group or a number of objects.

In another meaning subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

Given that sell of CDs in 1993 is 2.3 × 10⁶.

Sell of CDs in 2001 is 7.9 × 10⁷.

The difference between sell is = 7.9 × 10⁷ - 2.3 × 10⁶

Answer:

40 sides

Step-by-step explanation:

The number os sides can be calculated using

[tex]\frac{n(n-3)}{2}[/tex] = d ( n is number of sides and d number of diagonals )

Here d = 740 , then

[tex]\frac{n(n-3)}{2}[/tex] = 740 ( multiply both sides by 2 )

n(n - 3) = 1480

n² - 3n = 1480 ( subtract 1480 from both sides )

n² - 3n - 1480 = 0 ← in standard form

(n - 40)(n + 37) = 0 ← in factored form

Equate each factor to zero and solve for n

n - 40 = 0 ⇒ n = 40

n + 37 = 0 ⇒ n = - 37

A polygon cannot have a negative number of sides.

Then number of sides is 40

Flowers attract insects that transport gametes

Step-by-step explanation:

An advantage of flowering plants is that flowers attract insects that transport gametes. The correct option is A.

Flowering plants are generally called angiosperms. They bear flowers and fruits. There are more than 30,000 species of flowering plants. Flowering plants give beautiful or different colored flowers, and some flowers convert into fruit after some time.

Flowers have fragrances and vibrant colors. They have pollen or gametes which help in pollination. They attract many animals and insects towards themselves, and these animals help the plant to pollinate or dispersing of seeds. And insects and birds feed on the nectar of the flowers.

Thus, the correct option is A. Flowers attract insects that transport gametes.

Step-by-step explanation:

Given 60% of students passed , then 40% of students failed.

60% = 180 ( divide both sides by 60 )

1% = 3

Then

40% = 40 × 3 = 120

120 students failed the exam

If the number of students that passed was 180, the number of students who failed the examination is 120. So, correct option is A.

To determine the number of students who failed the examination, we need to find 40% of the total number of students.

We are given that 40% of the students failed, which means that 60% of the students passed. Since we know that the number of students who passed is 180, we can set up the following equation:

60% of total students = 180

To solve for the total number of students, we divide both sides of the equation by 60% (or 0.6):

Total students = 180 / 0.6

Calculating the right-hand side of the equation, we get:

Total students = 300

Therefore, the total number of students is 300.

To find the number of students who failed, we multiply the total number of students by the percentage who failed:

Number of students who failed = 300 * 40% = 120

Hence, option A, 120, is the correct answer.

Answer:

30°

Step-by-step explanation:

As the chord has same length of radius, the chord and the two radius form a equilateral triangle. Each angle of triangle is 60.So the chord subtended  at the center is 60. So the angle subtended at the remaining part of the circle = 30°

The measure of angle between the tangent and chord = 30  {Alternate segment theorem}

Answer:

Step-by-step explanation:

I posted a picture at the bottom of the post that you need to look at in order to understand this problem. I labeled everything inside that circle and then created a triangle. That triangle is made up of 3 sides that are all the same length, and that length is the length of the radius. By definition, if a triangle has all 3 of its sides the same length, it is equilateral. It is also equiangular. That means that every angle inside that triangle measures 60 degrees. The central angle, the one that comes off the center, intercepts an arc. The arc measure is the same measure as this angle, so the intercepted arc measures 60 degrees. To find the measure of the angle in question, the one you need that is labeled with a pink θ, has a rule that says the angle is going to be half the measure of the intercepted arc. That means that your angle is going to measure 30 degrees.

Step-by-step explanation:

One example of a measurement that requires high precision or a low level of uncertainty is the length of a silicon microchip. In the field of electronics manufacturing, even small variations in the length of a microchip can have significant impacts on its performance.

Therefore, it is essential to measure the length of a microchip with high precision, such as down to the nanometer scale, to ensure its functionality and reliability.

On the other hand, an example of a measurement that can have lower precision or a higher level of uncertainty is the temperature of a room. While temperature control is crucial in certain environments, such as a laboratory or a data center, in most cases, a general estimate of the temperature is sufficient.

A variation of a few degrees Celsius is unlikely to cause significant problems, making it unnecessary to measure the temperature with high precision.

The level of precision required for a measurement depends on the nature of the object being measured and the context in which the measurement is taken. In the case of the microchip, the manufacturing process is highly precise, and even small variations can lead to significant problems.

Therefore, it is essential to measure the length of the microchip with high precision. On the other hand, in the case of room temperature, the impact of small variations is usually insignificant, so a lower level of precision is acceptable. Overall, the precision required for a measurement depends on the importance of the measurement's accuracy and the potential consequences of imprecision.
