The average score of all students, calculated by taking a weighted average based on the number of students in each group, is 38. The overall performance is slightly below the group averages.

The average score of students in the first, second, and third groups are 39, 32, and 43, respectively. There are 24 students in the first group, 26 students in the second group, and 27 students in the third group.

To find the average score of all students, we need to take a weighted average of the scores in each group, with the number of students in each group as the weights.

Here's how to do it: First, we calculate the total number of students:24 + 26 + 27 = 77. Then, we calculate the total score across all students: 39*24 + 32*26 + 43*27 = 936 + 832 + 1161 = 2929

Finally, we divide the total score by the total number of students to get the average score:2929/77 = 38. The average score of all students is 38.

This means that the overall performance of all the students is slightly below the average of the scores in each group.

Step-by-step explanation:

It has one solution

For the linear equations provided by the coordinates in the table;

The first equation of this system is y = -2x.

The second equation of this system is y = x - 3.

The solution to the system is (1, -2).

We have four points (-5,10), (-1,2), (0,0), and (11,-22) for first equation, and four points (-8,-11), (-2,-5), (1,-2), and (7,4) the second equation.

The slope (m) is given by the formula (y2 - y1) / (x2 - x1).

For the first line, we can use the points (-5,10) and (-1,2)

m1 = (2 - 10) / (-1 - (-5)) = -8/4 = -2.

the first equation is y = -2x

the second line, we can use the points (-8,-11) and (-2,-5)

m2 = (-5 - -11) / (-2 - -8) = 6/6 = 1.

the second line has a slope of 1,

the equation should have the form y = x + c.

To find c, we can use one of the points, for instance (-2,-5):

-5 = -2 + c => c = -5 + 2 = -3.

So, the second equation is y = x - 3.

the solution to the system, we need to find where the two lines intersect.

y = -2x

y = x - 3

Setting both equation equally

-2x = x - 3

=> 3x = 3

=> x = 1.

Substituting x = 1 into the first equation

y = -2(1) = -2.

the solution to the system of linear equation would be (1, -2).

The type of sampling used to interview all the students at one table in the Commons is convenience sampling. The type of data that is collected by asking students their gender is qualitative data. The type of data that is collected by asking students their height is quantitative data. The type of data that is collected by asking students their gender is discrete data.

Convenience sampling is a type of non-probability sampling that is often used when it is difficult or time-consuming to obtain a random sample. In this case, the researcher would simply interview all the students who are sitting at a particular table. This type of sampling is not as reliable as random sampling, but it can be useful in certain situations.

Gender is a nominal scale measurement, which means that it is used to classify data into categories. The possible values for gender are male, female, and unspecified. Nominal scale measurements provide qualitative data.

Height is an interval scale measurement, which means that it has equal intervals between the values. The height of a person can take on an infinite number of values, so it is a continuous variable. Interval scale measurements provide quantitative data.

Discrete data is data that can only take on a finite number of values. The possible values for gender are male, female, and unspecified. This means that gender is a discrete variable.

Step-by-step explanation:

a) The probability distribution of t is: 1/6

b) The expected value E[t] is 3.5, and the variance Var(t) is approximately 2.917 for the roll of a fair die.

a. The probability distribution of t, the outcome of a roll with a fair die, can be described as follows:

Outcomes:

t = 1, 2, 3, 4, 5, 6

Corresponding probabilities:

P(t = 1) = P(t = 2) = P(t = 3) = P(t = 4) = P(t = 5) = P(t = 6) = 1/6

b. To determine E[t] (expected value or mean) and Var(t) (variance) for the probability distribution of t, we can use the following formulas:

Expected Value:

E[t] = Σ(t * P(t))

Variance:

Var(t) = Σ((t - E[t])² * P(t))

For the fair die, each outcome has an equal probability of 1/6.

E[t] = (1 * 1/6) + (2 * 1/6) + (3 * 1/6) + (4 * 1/6) + (5 * 1/6) + (6 * 1/6)

E[t] = 3.5

To calculate the variance, we need to subtract the mean (E[t]) from each outcome, square the difference, and multiply by the corresponding probability.

Var(t) = ((1 - 3.5)² * 1/6) + ((2 - 3.5)² * 1/6) + ((3 - 3.5)² * 1/6) + ((4 - 3.5)² * 1/6) + ((5 - 3.5)² * 1/6) + ((6 - 3.5)² * 1/6)

Var(t) = 35/12 ≈ 2.917

Therefore, the expected value E[t] is 3.5, and the variance Var(t) is approximately 2.917 for the roll of a fair die.

Step-by-step explanation:

Precision means that a measurement using a particular tool or implement produces similar results every single time it is used. For example, if you step on a scale five times in a row, a precise scale would give you the same weight each time. In math and science, calculating precision is essential to determine if your tools and measurements work well enough to get good data. You can report precision of any data set using the range of values, the average deviation, or the standard deviation.

The angle ABD is 35 degrees, AC is 20 units long, and AB is 29 units long.

An angle is created by combining two rays (half-lines) that have a common terminal. The angle's vertex is the latter, while the rays are alternately referred to as the angle's legs and its arms.

Triangle ABD's angle ABC is one of its outside angles, making it equal to the sum of the opposing interior angles.

Angle ABC = Angle ABD + Angle ACD

replacing the specified values:

110° = Angle ABD + 75°

Simplifying:

Angle ABD = 110° - 75°

Angle ABD = 35°

Due of their shared angles, the two triangles are comparable. This fact can be used to establish a ratio between the corresponding sides:

AC / CD = AB / BD

replacing the specified values:

AC / 10 = 16 / 8

AC = 20

1. The equation of the perpendicular line is: y = -x + 4

2. The equation of the parallel line is: y = -x + 4

The equations of two lines that are parallel to each other will have the slope (m), while the equations of two lines that are perpendicular to each other will have slope values that are negative reciprocals of each other.

The slope-intercept form for the equation of a line is, y = mx + b, where b is the y-intercept and m is the slope of the line.

1. The slope (m) of y = x - 4 is 1. The line that is perpendicular to y = x - 4 would have a slope (m) of -1.

Substitute (a, b) = (1, 3) and m = -1 into y - b = m(x - a):

y - 3 = -1(x - 1)

Rewrite in slope-intercept form:

y - 3 = -x + 1

y = -x + 1 + 3

y = -x + 4

2. The slope (m) of y = -x - 4 is -1. The line that is parallel to y = -x - 4 would have a slope (m) of -1.

Substitute (a, b) = (3, 1) and m = -1 into y - b = m(x - a):

y - 1 = -1(x - 3)

Rewrite in slope-intercept form:

y - 1 = -x + 3

y = -x + 3 + 1

y = -x + 4

Answer:

Step-by-step explanation:

As it is given that the kit comes with 10-foot-long beams and the instructions say to cut each beam into two pieces such that one piece is 3 times the length of the other.

So, to cut that rope in such a way, the rope should be 12 feet long.

The long piece should measure as 7.5 feet or 7'6" (7 foot 6 inches).

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the length of the small piece, so the long one will be 3x.

We know that the length of each beam is 10 ft.

The total length of the uncut beam = 10 foot.

Using this information we can set up the equation and solve for x;

x + 3x = 10

4x = 10

x = 2.5

As x = 2.5 is the length of short piece, then the long piece measures as;

3x = 3(2.5) = 7.5 feet.

Thus, There are 12 inches in a foot that is 7.5 feet = 7'6"

Step-by-step explanation:

mrk me brainliest plz

i can't explain it i just look at a math problem and auotomatically know the answer

Answer:

(1) 5.50 + 0.88r ≤ 26.00; 23 rides

Step-by-step explanation:

First of all, please understand the equation itself. We are multiplying 0.88 by r, or the number of rides. First, lets determine how many rides Elisha can ride. 0.88 * 23 = 20.24. And 20.24 + 5.50 = 25.74. This is less than 26.00. Now, 0.88 * 24 = 21.12 + 5.50 = 26.7. Though not by much, this is more than 26.00, so, Elisha cannot ride more than 23 rides. That eliminates options (3) and (4). The difference between (1) and (2) is that in (1) we are multiplying 0.88 by r which is correct, however, option (2) is multiplying 5.50 by r which is incorrect. Thus we have our answer. However, please note one important thing. I want you to understand the reason for the "≤" sign as this is very different from <. The sign used here indicates "less than OR equal to" whereas the other is "less than." The sign used indicates that this is the MAX Elisha can spend but he could also spend less. This may seem simple but it is crucial to have a good understanding of this concept as you progress. Any further questions just comment! Hope this helps:) P.S. do not just take the answer!

Answer:

c = 16

Step-by-step explanation:

We have (a + b)² = a² + 2ab + b²

x² + 8x + c is of the form a² + 2ab + b²

where x² = a²

8x = 2ab

and c = b²

⇒ x² + 8x + c = (x + √c)² which is a perfect square

x² = a² ⇒ x = a

8x = 2ab

⇒ 8x = 2xb

⇒ b = 8x/(2x)

⇒ b = 4

c = b²

⇒ c = 4²

⇒ c = 16

(x + √c)² = (x + √16)²

= (x + 4)²

= x² + 2(x)(4) + 4²

= x² + 8x + 16

Therefore, c = 16 makes the expression a perfect square
