I dont understand the part "Would this be true if the numbers were-3, 5, -16, and -10?"

Using the normal distribution and the central limit theorem, it is found that the probabilities are given as follows:

24. Single person has an IQ score above 105: 0.3694.

25. Sample mean (55 people) above 105: 0.0067.

The z-score of a measure X of a variable that has mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation of IQ scores are given as follows:

[tex]\mu = 100, \sigma = 15[/tex]

The probability that a single person has an IQ score higher than 105 is one subtracted by the p-value of Z when X = 105, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (105 - 100)/15

Z = 0.33

Z = 0.33 has a p-value of 0.6306

1 - 0.6303 = 0.3694.

For the sample of 55, the standard error is:

[tex]s = \frac{15}{\sqrt{55}} = 2.02[/tex]

Hence:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (105 - 100)/2.02

Z = 2.48

Z = 2.48 has a p-value of 0.9933.

1 - 0.9933 = 0.0067.

The table and graph given show the information about two national parks.

It is required to find the rate of change of the population of the two parks between 2009 and 2014, and then determine the park that shows faster population growth during those years.

Notice that the variable x represents the number of years after 2005.

Hence, the years 2009 and 2014 represent, x=4 and x=9, respectively.

The formula for the rate of change of a function f(x) between x=a and x=b is given by the formula:

Calculate the rate of change for park A:

Substitute a=4 and b=9 into the formula:

Substitute f(9)=2870 and f(4)=2370 from the table for park A into the expression for the rate of change:

Calculate the rate of change for park B:

Substitute f(9)=2800 and f(4)=2200 from the graph of park B:

Notice that the rate of change in population for park B is higher than that of park A.

Hence, park B showed faster population growth during those years.

Answers:

Rate of change for park A= 100 swallows per year.

Rate of change for park B= 120 swallows per year.

Park B showed faster population growth during those years.

Recall that when two angles add to give 90 degrees, they are called "complementary angles" This is the case here where you are adding an unknown angle to one that measures 51 degrees to obtain a right angle (90 degrees)

The unknown angle (?) is called the "complementary angle to the 51 degree one.

Please select the third option :

C. Complementary.

Do you remember how it looks an angle that measures 90 degrees? It looks like the angle formed by a square edge, or by two lines that are perpendicular to each other.

When you have two angles one in contact (adjacent) to the other and the two together complete a right angle , those two angles are called complementary angles. There is nothing profound to derive from that, but that it is simply a definition.

Jonah picked total 626 cherry tomatoes if she licked 287 cherry tomatoes in May and 330 cherry tomatoes in June.

As the mentioned numbers are in hundreds and not in thousands, the number can not be rounded. Now we will need to perform addition to find the total number of cherry tomatoes picked by Jonah combined in May and June.

Total number of cherry tomatoes = 287 + 339

Performing addition to find the total number of cherry tomatoes picked by Jonah

Total number of cherry tomatoes = 626

Therefore, Jonah picked 626 cherry tomatoes combined in May and June.

Applying the definition of the adjacent angles of a trapezoid, the value of x in quadrilateral TUVS is: x = 4.

The adjacent angles of a trapezoid are the angles that are found on the same leg of the trapezoid, and they are said to be supplementary to each other because they have a sum of 180 degrees.

Given that quadrilateral TUVS is a trapezoid, where angles SVU and TSV are adjacent angles, therefore:

m∠SVU + m∠TSV = 180°

m∠SVU = 139°

m∠TSV = (14x - 15)°

Substitute

139 + (14x - 15) = 180

139 + 14x - 15 = 180

Combine like terms

124 + 14x = 180

14x = 180 - 124

14x = 56

14x/14 = 56/14

x = 4

The roots of an equation is "solutions" of the equation. Solutions are the numerical values equal to the variable after solving it.

To determine the sum and product of the roots of a quadratic equation, the equation has to be written in the form ax²+bx+c = 0

From that form, the sum of the roots is given by -b/c and the product is c/a

For example, we want to find the sum and product of the roots of the quadratic equation 3x²-x = 2

Notice that the equation is not written in the form described above. So, it has to be written as 3x²-x - 2 = 0

From this form, we see that  and a = 3, b = -1 and c = -2

Therefore, the sum is -b/a = 1/3  while the product is c/a = -2/3 = -2/3

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

End behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis. Said differently, the end behavior of a function explains the graph's trend when we look at the right end of the x-axis (as x approaches +∞) and the left end of the x-axis (as x approaches -∞).

The value of the angle x will be equal to 113.5°.

An angle may be defined as the figure which can be formed from two rays joining at a point. The lines will be called as the sides of the angle and the point at which the rays join is called vertex of the angle. There are generally 5 types of angles namely Acute angle, Obtuse angle, Reflex angle, Right angle and Complete angle. The value of a complete angle will be given as 360°. Since, in the question all the angles are measured to the nearest. So, the value of 59° could actually be something between 58.5° and 59.5°. Analogously, 108° is between 107.5° and 108.5°, and 81° is between 80.5° and 81.5°. Now, the summation of all four angles will be equal to 360°.

x + 58.5° + 107.5° + 80.5° = 360°

=> x = 360° - (58.5° + 107.5° + 80.5°)

=> x = 360° - 246.5°

=> x = 113.5° which is the required value.
