in convex quadrilateral wxyz, the degree measure of angle x is four times that of angle w. the measure of angle y is double that of angle x. lastly, the measure of angle z is 3 degrees larger than that of angle y. what is the degree measure of the largest angle in wxyz?

Answer:

I can provide you with a description of the graph.

The graph would have the distance on the y-axis and the time on the x-axis.

The first 60 miles of the journey would be represented by a straight line with a slope of 60/1=60, since the car is traveling at a constant speed of 60 mph.

The point where the first 60 miles ends would be (1,60) which is the time of one hour from London, the distance of 60 miles from London.

After the 30-minute break at the motorway services, the car would continue its journey at a constant speed of 70 mph. This part of the journey would be represented by a straight line with a slope of 70/1=70.

The point where the whole journey ends would be (4,200) which is the time of 4 hours from London, the distance of 200 miles from London.

Please note that it is assumed that the car doesn't stop during the second part of the journey.

The only value that is a solution of the inequality -9> -4+5x is the first one, x = -5.

Here we have the inequality:

-9> -4+5x

And we want to see which of the given values is a solution for that inequality.

The first option is x = -5

Replacing that value we will get:

-9 > -4 + 5*-5

-9 > - 4 - 25

-9 > -29

This is true.

The second option is x = 2

-9> -4+5*2

-9 > -4 + 10

-9 > 6

This is false.

The last option is x = -1

-9 > -4 + 5*-1

-9 > -9

This is false.

Then the only solution is the first one, x = -5.

The likelihood that a student chosen at random has any siblings is 0.777. This is determined by deducting from 1 the probability of having no siblings (0.223).

1. Get the probability of 0 siblings : 0.223

2. Subtract the probability of 0 siblings from 1 :

1 - 0.223

= 0.777

3. Round the result to 3 decimal places :

0.777

The probability of a student not having 0 siblings can be calculated by subtracting the probability of having 0 siblings from 1. The probability model created from the survey results is a 2-column table with 5 rows. Column 1 is labeled number of siblings with entries 0, 1, 2, 3, 4 or more. Column 2 is labeled probability with entries

0.223, 0.532, 0.121, 0.085, 0.039.

The probability of having 0 siblings is 0.223. To calculate the probability of not having 0 siblings, we subtract 0.223 from 1. This gives us 0.777, which is the probability of not having 0 siblings. This result should be rounded to 3 decimal places, giving us 0.777 as the final answer.

9,900 codes that are available for reckha.

There are a total of 10,000 possible three-digit codes when each digit is in the set {0,1,2,3,4,5,6,7,8,9}. Since each digit can take 10 different values, we can use the formula 10^3 = 1000 to calculate the total number of codes.

However, since reckha cannot choose a code that is the same as yours or one that is the same as yours except for switching the positions of two digits, we have to subtract these possibilities from the total. We can calculate the number of codes forbidden by subtracting the number of codes with the same digits in all three positions (10) and the number of codes with the same digits but different positions (90) from the total. This leaves us with 10,000 - (10 + 90) = 9,900 codes that are available for reckha.

The solution is 26, since gcd (26, a + 13) = 26 when a = 1183k, and            k = 1,3,5,7,9...

Let d = [tex](2a^{2} +29a + 65, a+ 13)[/tex]

Now, we can split [tex]2a^{2} + 29a + 65[/tex] in the following way, so that it becomes easier to factorise.

[tex]2a^{2} + 29a + 65 = (2a^{2} + 29a + 39) + 26[/tex]

From this, we can quantify and notice that -13 is one root of this equation, while the other root is -3/2.

Therefore, [tex]2a^{2} + 29a + 39 = (a+13)(2a+3)+26[/tex]

Thus, [tex]d = ((a+13)(2a+3)+26, a+ 13)[/tex]

The greatest common divisor (GCD) of two or more numbers is the greatest common factor number that divides them, exactly. It is also called the highest common factor (HCF).

Now, we can use Euclid's Algorithm.

[tex]= gcd (2a^{2} + 29a + 65, a + 13)\\= gcd (2a^{2} + 29a + 65 - 2a(a+13), a+13)\\= gcd (3a + 65, a + 13)\\= gcd (3a + 65 - 3a(a+13), a+13)\\= gcd (26, a + 13)[/tex]

This is necessarily 1, 2, 13, or 26, which we can see by just looking at the first term. By factoring 1183 and considering that [tex]a[/tex] is an odd multiple, then we should be able to conclude the answer.

The solution to the given exponential equation is 0.791.

What is a logarithm?

The logarithm is the inverse function of exponentiation in mathematics. That is, the exponent to which b must be raised to produce x is the logarithm of a number x to the base b.

Given exponential function is

5x⁻² = 8

Divide both sides by 5:

x⁻² = 8/5

x⁻² = 1.6

Taking logarithm of base x:

[tex]log_x(x^{-2})=log_x1.6[/tex]

-2 [tex]=log_x(1.6)[/tex]

The two points representing companies that have been in business for 3 years are (3, 0.42) and (3, 0.3).

The predicted value for the point (3, 0.42) can be calculated as:

The predicted value for the point (3, 0.3) is calculated as:

y = 0.091x + 0.060.

Answer:

The angle in radians is 4.6.

Note that it is expressed in radians, to convert it to degrees you need to multiply it by 180/π, but it is already rounded to the nearest 10th.

Step-by-step explanation:

To find the angle in radians to the nearest 10th, you need to use the relationship between the length of an arc, the radius of the circle, and the angle of the arc:

arc length = (angle in radians) * (radius)

In this case, the radius of the circle is 8.5 and the arc length is 38.9, so you can substitute these values into the equation:

38.9 = (angle in radians) * (8.5)

To solve for the angle in radians, you need to divide both sides of the equation by the radius:

angle in radians = 38.9 / 8.5

The angle in radians is 4.6.

Note that it is expressed in radians, to convert it to degrees you need to multiply it by 180/π, but it is already rounded to the nearest 10th.

The mean and standard deviation of the sampling distribution of the difference in sample means for 8 female and 8 male students who participated in the 2-mile run is -1.5 minutes and 2.413 minutes, respectively.

The mean of the sampling distribution of the difference in sample means is calculated by subtracting the mean of the female students from the mean of the male students, which is 7.3 - 8.8 = -1.5 minutes.

The standard deviation of the sampling distribution of the difference in sample means is calculated by taking the square root of the sum of the squares of the standard deviations of the two populations, which is sqrt(3.3^2 + 2.9^2) = 2.413 minutes.

Therefore, the mean and standard deviation of the sampling distribution of the difference in sample means is -1.5 minutes and 2.413 minutes, respectively.

Answer:

To solve this problem, we will use the following steps:

Step 1: We know that the amount of time it takes Susan to get from her residence to class averages 50 minutes, with a standard deviation of 5 minutes. So we can use this information to calculate the proportion of Susan's trips to class that would take less than 40 minutes.

Step 2: To calculate the proportion of Susan's trips to class that would take less than 40 minutes, we need to find the z-score for the value of 40 minutes. We can use the following formula to find the z-score:

z = (x - μ) / σ

Where x is the value we are interested in (40 minutes), μ is the mean (50 minutes), and σ is the standard deviation (5 minutes).

z = (40 - 50) / 5 = -2

Step 3: We can use a standard normal table or a calculator to find the proportion of Susan's trips to class that would take less than 40 minutes.

The proportion of Susan's trips to class that would take less than 40 minutes is 0.0228 or 2.28%.

Step 4: To calculate the proportion of Susan's trips to class that would take more than 50 minutes or less than 40 minutes, we need to find the proportion of Susan's trips to class that would take more than 50 minutes and add it to the proportion of Susan's trips to class that would take less than 40 minutes.

Step 5: To find the proportion of Susan's trips to class that would take more than 50 minutes, we need to find the z-score for the value of 50 minutes.

z = (50 - 50) / 5 = 0

Using a standard normal table or a calculator, the proportion of Susan's trips to class that would take more than 50 minutes is 0.5 or 50%.

Step 6: Finally, we can add the proportion of Susan's trips to class that would take more than 50 minutes and the proportion of Susan's trips to class that would take less than 40 minutes to find the proportion of Susan's trips to class that would take more than 50 minutes or less than 40 minutes.

0.50 + 0.0228 = 0.5228 or 52.28%
