The ANGLE BISECTOR mentioned in the problem is simply just a line that separates an angle in half.

Meaning if it bisects ∠SUT which is 34. It just means that it divides the angle 34 into 2 equal parts.

Therefore ∠1 is just one-half of the ∠SUT.

Therefore the measurement of ∠1 is 17°.

When the p-value for the difference between the observed experimental outcomes and the expected outcome is less than 5 percent (< 0.05), the experimental results a  to be statistically significant and different from the expected outcome.

The P value is defined as the probability of obtaining a result equal to or more extreme than what was observed. The P stands for probability. The p-value represents the probability of the occurrence of a given event. To put it more simply the p-value refers to the percentage of experiments in which the sample differences are larger or smaller than an observed value.

The possible values that a correlation coefficient, r, can take are bounded between -1 and +1, where the correlation coefficient (r) is a statistical measure that quantifies the degree and direction of the linear relationship between two variables.

It ranges from -1 to +1, where a value of -1 represents a perfect negative correlation, a value of 0 represents no linear correlation, and a value of +1 represents a perfect positive correlation.

The magnitude of the correlation coefficient indicates the strength of the relationship between the two variables. It is a numerical value that ranges from -1 to +1. The value of r indicates the degree of association between two variables.

A positive value of r indicates a positive correlation, meaning that as one variable increases, the other variable tends to increase as well. A negative value of r indicates a negative correlation, meaning that as one variable increases, the other variable tends to decrease.

Answer:

r = -3

Step-by-step explanation:

-8-6(r+4)=-8r-38 distribute -6 into the parentheses

-8-6r-24=-8r-38 simplify

-6r-32=-8r-38 add 8r to both sides

2r-32=-38 add 32 to both sides

2r=-6 divide both sides by 2

r = -3

Answer:

\(r=-3\)

Step-by-step explanation:

Alright.

\(-8-6(r+4)=-8r-38\)

First, we'll distribute that \(-6\).

\(-8-6r-24=-8r-38\)

Next, I'm going to move the \(-8r\) to the other side.

\(-8-6r-24+8r=-38\)

That means the sign changes. Now, I'll combine like terms on the left.

\(2r-32=-38\)

Now, I'll move the \(-32\) over to the right.

\(2r=-6\)

Divide both sides by 2.

\(r=-3\)

And we're done!

Step-by-step explanation:3*2/(2*12)=1/4 so our answer is 1/4.

The mean amount of snow per day is equal to 19 cm snow per day.

In Mathematics and Geometry, the mean for this set of data can be calculated by using the following formula:

Mean = [F(x)]/n

For the total amount of snow based on the frequency, we have;

Total amount of snow (s cm), F(x) = 5(8) + 15(10) + 25(7) + 35(2) + 45(3)

Total amount of snow (s cm), F(x) = 40 + 150 + 175 + 70 + 135

Total amount of snow (s cm), F(x) = 570

Now, we can calculate the mean amount of snow as follows;

Mean = 570/30

Mean = 19 cm snow per day.

The scenario with the greater traveling speed is Scenario 1 with a speed of 60 mph which is more than the speed in Scenario 2 with a speed of 55 mph.

The speed of a body is the ratio of the distance traveled to the time it takes to travel the distance.

The scenario in the question, obtained from a similar question on the website are as follows;

Scenario 1;

A graph of Traveling Time having Distance (miles) as the vertical axis and Time (hours) as the horizontal axis.

The points on the graph are; (1, 60), and (4, 240)

Scenario 2;

Scenario 2 consists of the equation; y = 55·x

Where;

x = The time duration in hours

y = The distance traveled in miles

The data in each scenario suggest a linear relationship, such that we get;

The speed = Distance/Time = The slope of the graph of the data

The slope of a linear relationship is the coefficient of x when the coefficient of y is 1

Therefore;

The speed of Scenario 1 = The slope = (240 - 60)/(4 - 1) = 60

The slope of Scenario 1 and therefore the speed is 60 miles/hour

The coefficient of x in the equation for Scenario 2; y = 55·x is 55, therefore;

The slope of Scenario 2 = 55 = The speed of Scenario 2

The speed of Scenario 2 = 55 miles/hour

Answer:

x = 4

Step-by-step explanation:

The interior angles of a triangle sum to 180°.

Therefore:

⇒ (5x + 20)° + (3x + 14)° + 114° = 180°

⇒ 5x + 20 + 3x + 14 + 114 = 180

Collect like terms:

⇒ 5x + 3x + 20 + 14 + 114 = 180

Combine like terms:

⇒ 8x + 148 = 180

Subtract 148 from both sides:

⇒ 8x + 148 - 148 = 180 - 148

⇒ 8x = 32

Divide both sides by 8:

⇒ 8x ÷ 8 = 32 ÷ 8

⇒ x = 4

Solution

Answer:

x = 4

Step-by-step explanation:

We know that,

the sum of the interior angles in a triangle is added up to 180°.

Accordingly,

5x + 20 + 114 + 3x + 14 = 180

Combine like terms.

8x + 148 = 180

Subtract 148 by both sides.

8x = 180 - 148

8x = 32

Divide both sides by 6.

Answer:

(-2 , 2)

Step-by-step explanation:

A(-8 , 2) = (x1 , y1)

B(4 , -2) = (x2 , y2)

midpoint = (x1 + x2/2  ,   y1 + y2/2)

=(-8 + 4/2  ,  2-(-2)/2)

=(-4/2  ,  2+2/2)

(-2  ,  2)

(3 , 7) = (x1 , y1)

(9 , 2) = (x2 , y2)

distance of PQ = \(\sqrt{(x2 - x1)^2 + (y2 - y1)^2}\)

=\(\sqrt{(9 - 3)^2 + (2 - 7)^2}\)

The angle CAD in the triangle is 17 degrees.

A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

The triangle ABD and ABC are right angle triangle.

Triangle ABC is an isosceles triangle. Therefore, the base angles are equal.

An isosceles triangle is a triangle that has two sides equal to each other and two angles equal to each other.

Therefore,

∠BAC = ∠BCA = 45 degrees

Hence,

∠CAD = 180 - 90 - 28 - 45

∠CAD = 17 degrees

The correct answer is b. Expected value. The mean of a discrete random variable generalizes the concept of expected value. The expected value of a discrete random variable is the weighted average of all possible outcomes, where the weights are the probabilities associated with each outcome.

It represents the long-term average value that we would expect to observe if we repeated the random experiment multiple times.

In the context of a discrete random variable, the mean (or expected value) is calculated by multiplying each possible value of the variable by its corresponding probability and summing them up. It provides a measure of central tendency and represents the average value we would expect to obtain from the random variable over a large number of trials.

The population mean (mean of a variable) refers to the average value of a variable in the entire population, not specifically related to a random variable. The sample mean is the average value of a variable calculated from a sample of observations. The distribution of a discrete random variable refers to the pattern of probabilities associated with each possible outcome of the variable.

In 100 million years, the seafloor spreading zone will create 10 million square kilometers of new surface area.


The seafloor spreading zone creates 1 centimeter of new crust over its entire 1000 kilometers length every year. To calculate the surface area created, we need to multiply the length of the zone by the amount of new crust created each year.

First, we convert the length from kilometers to centimeters: 1000 kilometers = 100,000,000 centimeters.
Then, we multiply the length by the amount of new crust created each year: 100,000,000 cm * 1 cm = 100,000,000 square centimeters.

Finally, we convert square centimeters to square kilometers: 100,000,000 cm^2 = 10,000 km^2. Therefore, in 100 million years, the seafloor spreading zone will create 10,000 square kilometers of new surface area.

Using equations we know that approximately 8 liters of water must be added in order to produce a 30% acid solution.

So, we know that:

Liters of water: x

25% of solution: 0.25 × 50

30% of solution: 0.30 (50 + x)

Now, form equations and calculate as follows:

0.25 × 50 = 0.30 (50 + x)

12.5 = 15 + 0.30x

15 + 0.30x = 12.5

15 + 0.30x - 15 = 12.5 -15

0.30x = -2.5

.030x/.30 = -2.5/.30

x = - 8.33

Since we can't add water in negative, hence it will be +.
