Answer 1

Theoretical probability is what might happen, but the experimental probability is definitely happens in trials. The probability in these cases is 0.25.

What is the difference between theoretical and experimental probability?

Theoretical probability is based on the total outcomes vs the desired outcomes; due to this, this is just the expectation of what will hapen. However, as this is mainly based on expectations, it is not completely accurate.

On the other hand, the experimental probability is based on the observation of reality as the probability is tested, which makes it more accurate.

What are the probabilites in the cases presented?

Desired outcomes /total outcomes

What is the short definition of a linear equation?

An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

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

ILL GIVE BRAINIEST
i need the steps too

Answers

Answer:

-6

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

-8+2=-6

smallest value = 4.largest value = 48.median = 24first quartile {Q1} = 12third quartile {Q3} = 36What is defined as the frequency table?

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.

The result for the frequency distribution is obtained.

The false statement is:

There are fewer data points in the lower two quartiles than in the upper two quartiles.

Because 50% values are below the median and 50% are above, meaning that there is an equal number of data points in the lower two quartiles than in the upper two quartiles.

The new coordinate for Point A' is A' = (-3, -3)

How to determine the new coordinate for Point A'?

The coordinates of the triangle are given as:

A (3, 4), B (7, 7), and C (8, 1)

The translation is given as:

6 units left and 7 units down

This can be represented as:

(x, y) = (x - 6, y - 7)

When the above translation rule is applied on vertex A, we have:

A' = (-3, -3)

Hence, the new coordinate for Point A' is A' = (-3, -3)

Explain why researchers formulate a null hypothesis in addition to a hypothesis when designing an experimental study.

Answers

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.

What is the null hypothesis?

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.
