Answer:

1) AD = 9 in

2) DE = 9.25 in

3) ∠EDC = 36°

4) ∠AEB = 108°

5) 11.5 in

Step-by-step explanation:

1) AD = BC = 9in

2) AC = BD (diagonals are equal)

⇒ BD = 14.25

⇒ BE + DE = 14.25

⇒ 5 + DE = 14.25

DE = 9.25

3) Since AB ║CD,

∠ABE = ∠EDC = 36°

4) ∠ABE = ∠BAE = 36°

Also ∠ABE + ∠BAE + ∠AEB = 180 (traingle ABE)

⇒ 36 + 36 + ∠AEB = 180

∠AEB = 108

5) midsegment = (AB + CD)/2

= (8 + 15)/2

11.5

Answer: answer is 72 you can  get it by either multiplying the height and the base by two and following the formula for area of a triangle or you can divide 36 by two and multiply that by 4

Step-by-step explanation:

Answer:

72 meters

Step-by-step explanation:

Working on 1 triangle at a time

How to find the area of a triangle: Base x Height divided by 2

So: 6 x 6 = 36

36 divided by 2 = 18

Each triangle is 18 meters

18 x 4 triangles = 72 meters

if the population standard deviation is increased while the sample size is 28, the confidence interval will become wider. This is because there is more variability in the sample mean, and therefore more uncertainty in the estimate of the population parameter.

If the sample size is 28 and the population standard deviation is increased, there will be a direct impact on the confidence interval. This is because the confidence interval is calculated based on the sample mean and the standard deviation. If the population standard deviation is increased, it means that there is more variability in the population. This increase in variability will lead to wider confidence intervals.
A confidence interval is a range of values that is likely to contain the true population parameter with a certain level of confidence. The width of the confidence interval is determined by the sample size, the standard deviation, and the level of confidence.
In this case, if the population standard deviation is increased, it means that the sample standard deviation will also increase. The sample mean will be relatively more variable than it would be if the population standard deviation was lower. This increase in variability will cause the confidence interval to become wider, as there is more uncertainty in the estimate of the population parameter.
In summary, if the population standard deviation is increased while the sample size is 28, the confidence interval will become wider. This is because there is more variability in the sample mean, and therefore more uncertainty in the estimate of the population parameter. It is important to note that increasing the sample size can help to reduce the impact of increased population standard deviation on the confidence interval, as a larger sample size provides more accurate estimates of the population parameter.

The inequality that represents all the solutions of -2(3x + 6) ≥ 4(x + 7) is x ≤ -4

From the question, we have the following parameters that can be used in our computation:

-2(3x + 6) ≥ 4(x + 7)

Divide both sides of the inequality by -2

So, we have the following representation

3x + 6 ≤ -2(x + 7)

Open the brackets

This gives

3x + 6 ≤ -2x - 14

Add 2x to both sides of the inequality

So, we have the following representations

5x + 6 ≤ -14

Subtract 6 from both sides of the inequality

So, we have the following representations

5x ≤ -20

Divide both side of the inequality

x ≤ -4

After rounding 475.189 to the nearest hundredth we get 475.19 .

Rounding of a number is a process of approximating the original number to some decimal points resulting the original number to shorten up for more explicit representation.

Rules of rounding a number to its nearest hundredth is,

The original number would be rounded up to two decimal places as it represents to its hundredth decimal place.

If the digit after the second decimal place of the original number is greater than (equals to) 5 then we round up the number, by increasing the previous place value digit by 1.

And if the digit after the second decimal place of the original number is lesser than 5 then we round down the number, by decreasing the previous place value digit by 1.

Here in 475.189 the digit after second decimal is 9 which is greater than 5, hence we round up the number by increasing the previous value (that is, second decimal digit)  by 1 we get 475.19 (to the nearest hundredth).

Step-by-step explanation:

To tile the bathroom, it would cost the amount of $20. To carpet the bedroom and living room, it would cost $72.

To calculate the cost of tiling the bathroom, we need to multiply the number of squares in the bathroom (4 x 2 = 8) by the cost per square foot ($5). 8 x $5 = $40. To calculate the cost of carpeting the bedroom and living room, we need to multiply the number of squares in the bedroom (5 x 4 = 20) and the living room (7 x 4 = 28) and add them together (20 + 28 = 48). Then multiply the total number of squares (48) by the cost per square yard ($18). 48 x $18 = $864.

To calculate the cost of tiling the bathroom, we need to multiply the number of squares in the bathroom (4 x 2 = 8) by the cost per square foot ($5). 8 x $5 = $40.

The execution of the code segment will result in statement2 being executed. The code segment contains a conditional statement that uses the logical OR operator (||) to combine two conditions.

The first condition checks whether the result of dividing num1 by num2 is less than 0, while the second condition checks whether the product of num1 and num2 is greater than 0.

Given that num1 is 0 and num2 is 10, the first condition will evaluate to false, because 0 divided by any positive number is 0. However, the second condition will evaluate to true, because the product of two non-zero numbers with the same sign is always positive.

Since the logical OR operator requires only one of the conditions to be true for the entire statement to be true, the overall result will be true. As a result, statement1 will not be executed, and statement2 will be executed instead.

The correct answer is option A - True. An array is a data structure in programming that allows you to store a collection of values of the same data type in a single variable.

Each value is assigned an index number, starting from 0, which represents its position in the array.  Arrays are useful in programming because they allow you to store and manipulate multiple values using a single variable. This can help simplify code and make it more efficient.

For example, if you wanted to store the grades of 10 students in a program, you could create an array of 10 elements and assign each grade to a specific index in the array.  In addition to storing data, arrays can also be used to perform calculations and manipulate data.

For example, you could use a loop to iterate through an array and calculate the average of all the values stored in the array. Overall, arrays are a powerful tool in programming that can help you organize and manipulate data.

By thinking of an array as a collection of variables contained within a single variable, you can better understand how arrays work and how to use them effectively in your programs.

The correct option is a) 1/2

The probability of obtaining a head after obtaining two heads from two tosses of a coin is 1/2.

What is probability?

Probability is a branch of mathematics concerned with the study of random events or occurrences.

Probability is a quantitative measure of the likelihood that a given event will occur.

Probability is usually given as a number between zero and one (0 ≤ P(E) ≤ 1), where,

P(E) = 0, the event is considered impossible, and

when P(E) = 1, the event is considered a certainty.

What is the probability of obtaining a head after obtaining two heads from two tosses of a coin?

After obtaining two heads from two tosses of a coin, the probability of obtaining a head on the next toss is given by:

Sample space, S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}where H is for head and T is for tail.

Therefore, the probability of obtaining a head after obtaining two heads from two tosses of a coin is given by:

P(E) = favorable outcomes/total outcomes

The favorable outcome in this case is {HHH, HHT, HTH, THH, TTH}.

Hence, P(E) = 5/10

                   = 1/2

Therefore, the correct option is a) 1/2.

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.

In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section, we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.

C. |5x - 4| > -8

Step-by-step explanation:

The absolute value of a number is its positive numerical value.

To determine which absolute value inequalities have all real solutions, isolate the absolute value on one side of the equation.

Option A

|5x - 7| < -2

No solutions, as an absolute value cannot be less than zero.

Option B

   |3x - 6| + 17 > 15

⇒ |3x - 6| + 17 - 17 > 15 - 17

⇒ |3x - 6| > -2

True for all values of x, as an absolute value is always positive and therefore will always be greater than -2.

Option C

|5x - 4| > -8

True for all values of x, as an absolute value is always positive and therefore will always be greater than -8.

Option D

-2|3x - 5 | > 3

Divide both sides by -2 (remembering to flip the inequality sign):

⇒ |3x - 5| < -³/₂

No solutions, as an absolute value cannot be less than zero.

Step-by-step explanation:

The probability of both representatives being girls is 39/158, or approximately 0.247.

To find the probability of both representatives being girls, we first need to find the probability of selecting a girl as the first representative, and then the probability of selecting another girl as the second representative, given that the first one was a girl.

The probability of selecting a girl as the first representative is 40/80, or 1/2, since there are 40 girls in the group of 80 students.

Once a girl has been chosen as the first representative, there will be 39 girls left in the group of 79 students (since one student has already been chosen), so the probability of selecting another girl as the second representative is 39/79.

To find the probability of both events occurring (selecting a girl as the first representative and then selecting another girl as the second representative), we multiply the probabilities together:

1/2 x 39/79 = 39/158

Therefore, the probability is 39/158, or approximately 0.247.
