Experimental and theoretical probabilities do not match; Field Trip B is the most popular with 32% relative frequency.

What is frequency?

Frequency refers to the number of times an event or observation occurs within a given period, sample size, or population. In the context of data analysis, frequency is often used to describe how often a particular value or category appears in a dataset or sample. It can be expressed as an absolute frequency (the actual number of times an event occurred) or a relative frequency (the proportion or percentage of times an event occurred compared to the total number of observations).

The experimental probability of selecting each field trip can be calculated by dividing the number of times each trip was selected by the total number of spins. For example, the experimental probability of selecting Field Trip A is 8/50 = 0.16 or 16%, the experimental probability of selecting Field Trip B is 16/50 = 0.32 or 32%, and so on.

The theoretical probability of selecting each field trip is 1/5 or 0.2 or 20%. This is because the spinner has 5 equal sections, and each section represents a different trip.

The experimental and theoretical probabilities do not match exactly. For example, the experimental  of selecting Field Trip B is 0.32 or 32%, while the theoretical probability is only 0.2 or 20%. This could be due to chance or random variation, as the teacher only spun the spinner 50 times. With a larger sample size, the experimental and theoretical probabilities should converge closer to each other.

The relative frequency of selecting each field trip can be calculated by dividing the number of times each trip was selected by the total number of spins, and then multiplying by 100 to express it as a percentage. For example, the relative frequency of selecting Field Trip A is (8/50) x 100 = 16%, the relative frequency of selecting Field Trip B is (16/50) x 100 = 32%, and so on.

Based on the data, Field Trip B appears to be the most popular, as it was selected the most number of times (16 times out of 50 spins).

all u got to do is subtract

f(x)=2x+7

domain: x = {2, 3, 5, 9}

Replace each x value and solve for y

x=2

f(2)= 2(2) + 7 = 4 + 7 = 11

x=3

f(3)= 2(3) + 7 = 6 + 7 = 13

x=5

f(5)= 2(5) + 7 = 10 + 7 = 17

x=9

f(9)= 2(9) + 7 = 18 + 7 = 25

We can find the range of the function by plugging in each value in the domain into the function and listing the output values:

When x = 2, f(2) = 2(2) + 7 = 11

When x = 3, f(3) = 2(3) + 7 = 13

When x = 5, f(5) = 2(5) + 7 = 17

When x = 9, f(9) = 2(9) + 7 = 25

Therefore, the range of the function for the given domain is y = {11, 13, 17, 25}.

Hence, the correct answer is B. y = {11, 13, 17, 25}.

As a result, the triangle QRS has a surface area of **10√(58) square units**.

Define triangle area.

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to half the height times the base, or A = 1/2× b × h Triangle area is measured in square units, such as m² cm², in², and so forth

Triangle QRS's area can be calculated using the triangle's area formula. The equation is:

Area equals 1/2*base*height

where base and height refer to the triangle's base and height, respectively.

By utilizing the distance formula to calculate the sides' lengths, we can determine the triangle QRS's base and height. The formula for distance is:

(d) = √((x2 - x1)² +√ (y2 - y1))²

where d is the separation between (x1, y1)'s points and (x2, y2).

This formula allows us to determine that:

- The QR is long √(29)

√(10) is the length of RS.

is the length of QS √(20)

The base can be the length of QS, and the height can be the length of QR. Therefore, there are:

Area = 1/2 × base× height

    = 1/2 × √(20) * √(29)

    = 1/2 × √(580)

    = 10√(58)

The absolute value equation that has -8 and -2 as the solution set is |x + 5| = 3

What is an absolute value equation?

An absolute value equation can be written as |expression| = value

To have -8 and -2 as the solution set, we need an absolute value equation that produces these two values when the expression inside the absolute value is either positive or negative.

We can write,

|x + 5| = 3

To solve for x, we have two cases,

Case 1: x + 5 is positive

If x + 5 is positive, then the equation becomes x + 5 = 3

Solving for x,

x = -2

This matches one of the solutions we want.

Case 2: x + 5 is negative

If x + 5 is negative, then the equation becomes -(x + 5) = 3

Solving for x,

x = -8

This also matches the other solution we want.

Therefore, the absolute value equation that has -8 and -2 as the solution set is |x + 5| = 3.

Explanation:

Focus on triangle BDH

The three inside angles of any triangle always add to 180 degrees.

B+D+H = 180

47+31+H = 180

78+H = 180

H = 180-78

H = 102

Angle BHD is 102 degrees.

It adds to angle x, aka angle BHC, to get 180 degrees. These two adjacent angles combine to a straight line.

(angle BHD) + (angle BHC) = 180

102 + x = 180

x = 180-102

Answer: Total distance of the swimming competition is 55.56 km.

Step-by-step explanation:

Let x be the total distance of the swimming competition.

On the first day, Angie covered 25% of the total distance, which means she swam 0.25x km.

On the second day, she covered one-third of the remaining distance, which is (1 - 0.25)x = 0.75x km.

So, she swam (1/3) * 0.75x = 0.25x km on the second day.

On the third day, she covered 25% of the remaining distance, which is (1 - 0.25 - 1/3)x = 0.42x km.

So, she swam 0.25 * 0.42x = 0.105x km on the third day.

On the final day, she swam half of the remaining distance,

which is (1 - 0.25 - 1/3 - 0.5)x = 0.125x km.

The total distance she swam is the sum of the distances swum on each day:

0.25x + 0.25x + 0.105x + 0.125x = 0.73x

We know that the total distance of the competition is x - 15 km (since she still has 15 km left to swim).

So we can set up the equation:

0.73x = x - 15

Solving for x, we get:

x-0.73x = 15

0.27x = 15

x = 55.56

Therefore, the total distance of the swimming competition is 55.56 km.

The area of a circle is given by the formula  [tex]A = \pi r^2,[/tex] where r is the radius of the circle.

Circumcircle:

The radius of the circumcircle, denoted as R, can be calculated using the formula:

[tex]R = (a \times b \times c) / (4 \times Area)[/tex] , where Area is the area of the triangle. The area of the triangle can be calculated using Heron's formula:

We find that P(Z > 2.46) is roughly 0.007 using a calculator or a basic normal distribution table. The probability that a bag will contain more than 20% blue jellybeans is therefore approximately 0.007 or 0.7%.

The probability of an event is the ratio of good outcomes to all other potential outcomes. The number of successful outcomes for an experiment with 'n' outcomes can be expressed using the symbol x.

Here in the question,

We can utilise the binomial distribution formula to resolve this issue. In a bag of 200 jelly beans, let X represent the proportion of blue jelly beans. Following that, X exhibits a binomial distribution with parameters of n = 200 and p = 0.15, where p is the likelihood of drawing a blue jellybean.

The formula for determining the likelihood of finding more than 20% blue jellybeans in a bag is:

P (X > 0.2 × 200) = P (X > 40)

Since n is large (200) and p is not too near to 0 or 1, we can utilise the usual approximation to the binomial distribution. We may determine the equivalent mean and standard deviation of the normal distribution by using the mean and variance of the binomial distribution:

μ = np = 200 × 0.15 = 30

σ = √ (np(1-p)) = √ (200 × 0.15 × (1-0.15)) = 4.07

Then, we can standardize the random variable X as:

Z = (X - μ) / σ

So, we have:

P(X > 40) = P((X - μ) / σ > (40 - μ) / σ)

= P(Z > (40 - 30) / 4.07)

= P(Z > 2.46)

We find that P(Z > 2.46) is roughly 0.007 using a calculator or a basic normal distribution table. The likelihood that a bag will contain more than 20% blue jellybeans is therefore approximately 0.007 or 0.7%.

So the unit multiplier used would be:

([tex]\frac{1L}{1000mL}[/tex]) OR  ([tex]\frac{1000mL}{1L}[/tex])

The initial unit is “mL” which has to be cancelled out (by the correct unit multiplier) so that the final answer is expressed in the desired units of “L”. Therefore the unit multiplier shown on the left will be used:

∴[tex](1267.1mL)[/tex] × [tex](\frac{1L}{1000mL})[/tex]

= [tex]\frac{1267.1}{1000}[/tex] L

= 1.2671 L

Thus, the solution of the given cosine function is obtained for the angles-  θ = 30º and θ = 330º between the intervals of [0,2pi).

The ratio of the triangle's side next to the angle to the hypotenuse is known as the cosine function. Thus, the cosine function does have a period of 2π, we can say.

Normally, radians rather than degrees are used when examining the cosine function in this manner. The common unit of measurement for angles in mathematics is the radian. 360° is equivalent to two radians, or one full circle.

Given data:

1-cosθ = (2-√3)/2

cosθ = 1-(2-√3)/2

isolating the cosθ function:

cosθ = 1-(1-[√3/2])

cosθ = 1-1+√3/2

cosθ = √3/2

Now,

cos is  √3/2 for ∏/6 = 30º and for 11∏/6 = 330º (Interval - [0,2pi))

Thus, the solution of the given cosine function is obtained for the angles-

θ = 30º and θ = 330º between the intervals of [0,2pi).

The position of  √17 between 4 and 5, which is nearer 5, and the location of 6, which is between 2 and 3, which is nearer 2.

A visual representation of real numbers in a linear manner is a number line. It is a straight line that is divided into intervals or segments, each of which stands for a distinct real number value.

Number lines can be vertical or horizontally oriented, and they can also have a positive or negative orientation. Positive numbers often extend to the right or up, whereas negative numbers typically extend to the left or down. The origin of the number line, or zero, is typically situated in the middle of the line.

The number line is a crucial tool in mathematics since it offers a means of representing numerical relationships visually and carrying out fundamental arithmetic operations. For instance, positive and negative motions along a number line can be used to depict addition and subtraction, respectively, with positive movements denoting addition and negative movements denoting subtraction. On a number line, multiplication and division can alternatively be shown as repeated addition or subtraction.

If we have a number line with the proper markings, we may indicate where the square roots of 17 and 6 are located as follows:

To begin, determine the approximate square root values:

√17 is between 4 and 5, since 4² = 16 and 5² = 25.

√6 is between 2 and 3, since 2² = 4 and 3² = 9.

Place the number √17 closer to 5, between 4 and 5.

Place the number √6 between the numbers 2 and 3, closer to 2.

Since 6 and 17 are not integers and their values are not evenly spaced, it should be noted that their markings will not be evenly spaced on the number line.
