Ms. Flores using to add these numbers in this order is follow Commutative Property of Addition.

What is Commutative Property of Addition?

No matter what sequence the addends are in when we add two or more integers, the result is always the same. This characteristic may be expressed as A + B Equals B + A. In this case, 2+4=4 + 2 = 6. Due to the fact that the total of both phrases is 6, 2+4 is equivalent to 4+2. The Commutative Property of Addition refers to this.

On the first bus there were 14 students, on the second, 18 students, and on the third bus there were 12 students. The total number of students would then be: 14+18+12=44.

Ms. Flores decides to add 18 and 12 to get 30

18+12= 30

And then adds 14

Trigonometric functions are referred to as Circular Functions will be merely outlined because the functions of associate degree angle of a triangle.

The difference in y values from max to min = 15. 15/2 = a
max cosine = 1, min cosine =-1
7.5 x 1 - 1.5 = 6
7.5x -1 -1.5 = -7.5-1.5= -9
h(x) = 7.5cos(bx+c) -1.5
now just get a period or frequency that matches the x coordinates 3 and 6.5 to get b and c
at (3,6) cosine = 1 to get a maximum value. cosine is at a max when cos(bx+c) = 1 and bx+c=0, 360, 720...
if x=3, then 3b +c=0 and c=-3b
for (6.5,-9) to be a minimum h value, then cos(6.5b+c) =-1 that happens when the angle = 180. +n360 for any integer n. 6.5b+c = 180
c= 180-6.5b
c=-3b
180-6.5b =-3b
add 6.5b to both sides to get
180= 3.5b
b = 180/3.5 = 51 1/7
c=-3b = -153 3/7
h(x) = 7.5cos(51.4x - 154.3)-1.5

In order to increase the likelihood that a blue marble would be drawn at random to 3/4, we must thus add 32 more blue marbles.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to express probabilities.

Here,

Let the number of blue marbles added be x,

Probability=3/4

Total marbles=20

Number of blue marbles=7

(7+x)/(20+x)=3/4

4(7+x)=3(20+x)

28+4x=60+3x

x=60-28

x=32

flips a fair coin five times, 5/16 is the probability that there are 3 heads in a row somewhere in the sequence of five flips.

The number of positive outcomes to all possible outcomes of an event is the ratio, which is known as probability.

The number of positive outcomes may be expressed by x for an experiment with n number of outcomes.

The following equation can be used to determine an event's probability:

Probability(Event) = Favorable outcomes / Total Outcomes = x/n

Considering a fair coin, after 5 flips, there are [tex]2^5[/tex] = 32 different arrangements of heads and tails.

To get exactly 3 heads,

[tex]^5C_3[/tex] = 5! / (5 - 3)! 3!

     = 5!/ 3! 2!

P(exactly 3 heads) = 10/32 = 5/16

The angles,  x = 11 and y = 3,if l ll m,

When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.

When two lines meet at a point, an angle is created.

An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.

Angles are a common occurrence in daily life.

Angles are used by engineers and architects to create highways, structures, and sports venues.

According to our question-

A transversal intersects the parallel lines marked by the letters "l" and "m.

The two suplementary angles have the radii (13x - 19°) and (17y + 5)°, respectively.

Thus, (13x - 19)° plus (17y + 5)° equals 180°.

13x + 17y = 180 + 14

13x + 17y = 194 ————(1) (1)

The comparable angles are (9x + 25) and (13x - 19).

Consequently, (9x + 25) = (13x - 19)

9x - 13x = -19 - 25

-4x = -44

x = 11

By changing equation's value for 'x' (1),

13x + 17y = 194

13(11) + 17y = 194

17y = 194 - 143

17y = 51

y = 3

As a result, the solution will be x = 11 and y = 3.

The area of land inside the fence is 7600 square feet.

What is the area of the triangle?

If the height of the triangle is 'h' and the base is 'b', then the area of the triangle can be computed by using the formula,

           Area = 1/2 * base * height

To find the area of the land inside the fence, we can use the formula for the area of a right triangle:

Area = (1/2) * a * b

where a is the length of one of the legs of the triangle and b is the length of the hypotenuse.

We are given that the length of fence b is 130 feet and that the measure of angle A is 42°. Since the triangle is right, angle A is complementary to angle 90°, so the measure of angle A is 90° - 42° = 48°. Since the measure of angle A is 48°, the other leg of the triangle (which we will call "a") is the side opposite angle A.

We can use the sine function to find the length of side a:

a = b * sin A

= 130 * sin 48°

= approximately 117.3 feet

Substituting these values into the formula for the area of a right triangle gives:

Area = (1/2) * 117.3 feet * 130 feet

= approximately 7600.5 square feet

Rounded to the nearest square foot, the area of land inside the fence is 7600 square feet.

Kayla earned $188 total, so 10L+ 21t = 188(the number of hours spent lifeguarding/tutoring times how much she gets paid every hour).

A sampling distribution is the probability distribution of a statistic that was acquired from more samples taken from a certain population. The distribution of frequencies for a variety of potential outcomes that could happen for a population statistic makes up the sampling distribution of a specific population.

When it comes to the spread of all sample proportions, theory predicts behaviour far more accurately than just stating that larger samples have a smaller spread. In actuality, the sample size, n, and the standard deviation of each sample proportion.

Representative fraction is a form of scale that can be used to change the size of an object to form an image. The required length is 32 inches.

A scale is a fraction of numbers that can be used to either increase or decrease the size of a given object. It is majorly referred to as representative fraction in scale drawing.

Representative fraction = [tex]\frac{length on drawing}{original length}[/tex]

In the given question, we have;

12 inches = 1 feet

x inches = 30 feet

So that:

x = 30 x 12 inches

  = 360 inches

representative fraction = [tex]\frac{2 inches}{360 inches}[/tex]

                             = 5.56 x [tex]10^{-3}[/tex]

Thus, given that the length of the Alamo Mission is 480 feet long. Then:

480 feet = 480 x 12 inches

              = 5760 inches

So that,

the required length in inches = 5760 x 5.56 x [tex]10^{-3}[/tex]

                                             = 32 inches

Step-by-step explanation:

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is:((x1 + x2)/2, (y1 + y2)/2)Substituting the coordinates of points P and Q into the formula, we get:((2 + (-7))/2, (4 + (-2))/2) = (-2.5, 1)The coordinates of the midpoint of segment PQ are (-2.5, 1).To verify that this point is on the line through P and Q, we can find the slope of the line using the coordinates of points P and Q:slope = (y2 - y1)/(x2 - x1) = (-2 - 4)/(-7 - 2) = -6/-9 = 2/3We can then use the point-slope form of a linear equation to write the equation of the line through points P and Q:y - y1 = m(x - x1)

y - 4 = (2/3)(x - 2)We can substitute the coordinates of the midpoint (-2.5, 1) into this equation to see if it is a solution:1 - 4 = (2/3)(-2.5 - 2)

-3 = -10/3The equation is true, so the midpoint (-2.5, 1) is on the line through points P and Q.To show that this point is just as far from P as it is from Q, we can use the distance formula to find the distance from the midpoint to points P and Q:distance = √((x2 - x1)^2 + (y2 - y1)^2)distance from (-2.5, 1) to (2, 4) = √((2 - (-2.5))^2 + (4 - 1)^2) = √(4.5^2 + 3^2) = √(20.25 + 9) = √(29.25) = 5.4distance from (-2.5, 1) to (-7, -2) = √((-7 - (-2.5))^2 + (-2 - 1)^2) = √(4.5^2 + 3^2) = √(20.25 + 9) = √(29.25) = 5.4. Since the distance from the midpoint to points P and Q is the same, the midpoint is just as far from P as it is from Q.
