On average, it fell about 0.2 degrees between 1910 and 1950

On average, it rose about 0.3 degrees between 1910 and 1950

On average, it rose about 0.5 degrees between 1910 and 1950

On average, it rose about 0.8 degrees between 1910 and 1950

Answer:

The answer is C

Step-by-step explanation:

The first step is to multiply 154 and 63 to find the product. The product of those two numbers is 9702.

So the the equation looks like...

462+ Blank = 9702

The easiest thing to do here is subtract 462 from both sides. So 9702-462 which would equal 9240.

So we'll say that the blank is x so now the equation says...

x = 9240

All values of x in the interval [0, 2] that satisfy the equation are [tex]\frac{\pi }{2} ,3\frac{\pi }{2}[/tex].

A mathematical equation is a formula that uses the equals symbol (=) to connect two expressions and express their equality. A well-formed formula consisting of two expressions linked by an equals sign is considered to be an equation in English, but the word's cognates in other languages may have slightly different definitions. For instance, an équation is defined as having one or more variables in French.

The first step in resolving a variable equation is to identify the values of the variables that lead to the equality being true. The variables that must be changed in order to solve the equation are referred to as the unknowns, and the values of the unknowns that satisfy the equality are referred to as the equation's solutions.

Answer:

f'(1) = -64

Step-by-step explanation:

To find f'(1), we will be finding the f'(x) first which means the first derivative of f(x), we can find the derivative by using chain rule to this function.

The formula of chain rule is:

[tex]\displaystyle f(u) = u^n \to f'(u) = nu^{n-1}\cdot u'[/tex]

In simple explanation, we derive normally (power rule) then multiply by the derivative of inside (u).

Applying the formula, we will have:

[tex]\displaystyle{f'(x)=4(x^2-3)^{4-1}\cdot (x^2-3)'}\\\\\displaystyle{f'(x)=4(x^2-3)^{3}\cdot 2x}\\\\\displaystyle{f'(x)=8x(x^2-3)^{3}}[/tex]

Substitute x = 1 in the f'(x):

[tex]\displaystyle{f'(1)=8(1)(1^2-3)^3}\\\\\displaystyle{f'(1)=8(1-3)^3}\\\\\displaystyle{f'(1)=8(-2)^3}\\\\\displaystyle{f'(1)=8(-8)}\\\\\displaystyle{f'(1)=-64}[/tex]

Answer:

124.67 feet per second

Step-by-step explanation:

First: multiply the feet per mile by the amount of miles that the car is going in order to get the feet per hour

5280 x 85 = 448,800

Second: divide the answer from the first step by 60 in order to get the number of feet per minute

448,800 ÷ 60 = 7480

Third: divide the answer from the second step by 60 in order to get the number of feet per second

7480 ÷ 60 = 124.67

PABc = 3/36

PABc = 1/12.

Two dice are tossed.

Assume that each possible outcome has 1/36.

Let A be the event the probability of getting some of the faces showing is 6.

A = 1,5,5,12,44,23,3

Let B be the event that the face showing one die is twice on the other.

That is,

B =1,22,12,44,23,66,3

There are 36-6=30 events in Bc

However, A and Bc will only be having 3 pairs together = 1,55,13,3

Therefore,

PABc = 3/36

PABc = 1/12.

How many outcomes are possible for the sum of the faces showing?

There are countless outcomes that could occur. The sum of the faces shown has an endless number of outcomes. This is due to the fact that there are an endless number of ways to flip a coin, which will produce various combinations on the faces that are displayed. The sum of the faces and the tails has an endless number of outcomes. There are only two outcomes that can occur while tossing a coin because the total number of outcomes is always even.

Population growth is the rise in the number of inhabitants in a population or scattered group and it is usually stated in percentage.

Researchers often focus on four primary elements when forecasting changes in population size:

Other factors include:

Age distribution and statistics allow the pace of population growth to rise or decline as it is linked to the level of economic development of a population.  a fast-expanding country's population has a pyramid-shaped age structure, with a higher share of younger people of reproductive age.

The probability or chance of Tara being selected is 1/29.

Probability is the chance of happening something or the occurrence of something . We can also define the probability as the chance of occurring or the chance of selecting something from the total set of value. It is always ranges from 0 to 1 where 0 is minimum value and 1 is maximum value of probability.

Formula for probability is :

[tex]P(Event) =\frac{ Chance \ of \ occurring \ that \ event}{total \ occurance}[/tex]

where, the total occurrence is the sample space of our given data or we can say the total number of values in the sample space.

In the given question,

Chance of selecting Kenny = 1 / 29

=> P(Kenny is selected) = 1/29

That means sample space consist of 29 values.

The absolute value for 3 is 3 .

The absolute value for 5 is 5.

The two solutions are the shortest and longest permitted lengths, The absolute value |2x−5|+|2x−3|=2

Absolute value is the non-negative value of a real number x, independent of its sign, is its absolute value (or modulus), | x |.

For example, 5 has an absolute value of 5, and -5 has a value of 5. Another way to think about a number's absolute value is as its distance from zero on the real number line. In addition, the distance between two real numbers is the absolute value of their difference.

Given that,

A routine may be no less than 3 minutes in length and no more than 5 minutes in total.

By absolute value equation

we can get 2x−5|+|2x−3|=m

By solving we get 2 m values they are,

The ordered pairs of the solutions for this system of equations is (-2,11) and (-1,6)

Two integers written in a certain order make up an ordered pair. As a result, we may define an ordered pair as a pair of components that appear in brackets and in a specific order.

These equations are composed of a line and a parabola. The intersection points between them must be located:

[tex]y=x^2-2x+3[/tex]

y=-5x+1

Thus,

[tex]x^2-2x+3=-5x+1[/tex]

[tex]x^2-2x+5x+3-1=0[/tex]

[tex]x^2+3x+2=0[/tex]

[tex]x^2+x+2x+2=0[/tex]

[tex]x(x+1)+2(x+1)=0[/tex]

x+2=0, x=-2

x+1=0, x=-1

Since the quadratic expression may be factored out, the following x-values represent the system's solution:

x=-2 and x=-1

Now, we may obtain the corresponding y values using either of the system's original equations. We decide to use a linear equation as an illustration:

When x =-2,

y=11
