Look at the mapping diagrams below, which represent two different relations. The relation on the
left is a function since each value in the blue set is paired with one value in the yellow set. For
the function on the left, the domain is {0, 1, 2, 3) and the range is {0, 1.69, 3.38, 5.07).

The mean is the population of city in 2026.

What is the short definition of a linear equation?

a) From the meaning of title -

 f(t) = 3000t + 34000              { from 2020 it will be increase by 300 people                              

                                                            per year}

b) f(b) = 3000 × 6  + 34000

          = 18000  + 34000

          = 52000

The complete question is -

Let f(t) be the population (in thousands of people) of Math City, as a function the time t (in years), where t = 0 corresponds to the year 2020. In 2020, the population was 34000, and each year the population increases by 3000 people. (a) Model the population by finding a formula for f(t), using the appropriate choice of a linear, polynomial, power, trigonometric, or exponential function, or a piecewise combination thereof. (b) Evaluate the expression f(6), and write a sentence explaining what this means. (c) Solve the equation f(t) = 64, and write a sentence explaining what this means

A null hypothesis outlines what a researcher should see if the tested hypothesis is incorrect. In essence, it presents an "alternative" theory to the first.

The null hypothesis is a type of hypothesis that explains the population parameter and is used to examine if the provided experimental data are reliable. Depending on whether the population or sample under consideration is viable, this hypothesis is either rejected or not. Or to put it another way, the null hypothesis is a hypothesis that assumes that the sample observations are the result of chance. It is claimed to be a claim made by surveyors who wish to look at the data.

The basic idea behind null hypothesis testing is to gather data and calculate the probabilities of a particular set of data during an experiment on a random sample, presuming that the null hypothesis is correct.

Using the normal distribution, it is found that 21% of the riders go on more than 10 rides.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

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

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 8.4, \sigma = 2[/tex]

The proportion of riders that go on more than 10 rides is one subtracted by the p-value of Z when X = 10, hence:

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

Z = (10 - 8.4)/2

Z = 0.8

Z = 0.8 has a p-value of 0.7881.

1 - 0.7881 = 0.2119 = 21.19% = 21%(rounded to the nearest percent)

21% of the riders go on more than 10 rides.

The two irrational numbers that sum up to 2 are (√5 - 2) and (4 - √5)

Irrational numbers are numbers that cannot be expressed or written as a quotient of integers.

Example of irrational numbers are; √5 , √7, √3, etc

Irrational numbers that can add up to 2

(√5 - 2) + (4 - √5)

expand the bracket

√5-2 + 4-√5

collect like terms

√5 - √5 -2 + 4

Rounded to the nearest Tenths Place.

The rate constant K is 0.0015.

Zero-order reaction of reactant a is found to have [a]0=0.25 m and

if [a]=0.10 m at t=100s, then we need to find the rate constant k.

The rate constant, k, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction

k=([a]0-[a])/t

where k is rate constant,

By the given data we have [a]0=0.25 m

[a]=0.10 m

t=100s

k=?

The rate constant, is a proportionality constant that indicates the relationship between the molar concentration of reactants and the rate of a chemical reaction.

The rate constant is denoted by k.

k=([a]0-[a])/t

Subtract 0.10 from 0.25 and divide it by 100

=(0.25-0.10)/100

=0.15/100

=0.0015

Therefore 0.0015 is the rate constant when a zero-order reaction of reactant a is found to have [a]0=0.25 m and [a]=0.10 m at t=100.

A frequency table is merely a "t-chart" or two-column table that illustrates the numerous possible outcomes and associated frequencies demonstrated in a sample.

Part 1: Smallest value;

As the frequency table is continuous distribution with a initial value of 4.

Thus, the smallest value of the table is 4.

Part 2: largest value;

As the frequency table is continuous distribution with a final value of 48.

Thus, the largest value of the table is 48.

Part 3: Median

The median is the number in the middle of a sorted list of numbers, and it is more descriptive of the data set than that of the average.

For even number of frequencies.

median = n/2

median = 12/2 = 6

Thus, the 6th term is the median.

median = 24.

Part 4: first quartile {Q1}

When data points are organized in increasing order, the lower quartile, or the first quartile (Q1), is indeed the value at which 25% of them are found.

Thus, Q1 = 12.

Part 3: third quartile {Q3}

When arranged in increasing order, the upper quartile, as well as third quartile (Q3), has been the value at which 75% of data points are found.

Q3 = 36.

Answer:

Step-by-step explanation:

use PEMDAS

start with the exponent: (-4)^2=16

-12 / 3 * (-8 + 16 - 6) +2

then the parentheses: (-8+16-6)=2

-12 / 3 * 2 +2

next is multiplication/division, division comes first so: -12/3=-4

-4 * 2 +2

then multiplication: -4*2=-8
