What is a counterexample for the conjecture?

Mathematics
1 answer:
Dmitriy789 [7]3 years ago
4 0

Answer:

A counterexample for a conjecture is the statement that disproves a conjecture.

Step-by-step explanation:

To find : What is a counterexample for the conjecture?

Solution :

A conjecture is an educated guess but not yet proven. It is possible that next example shown the conjecture wrong.

A counterexample is an example that disproves or disagree a conjecture.

For example : Prime numbers - 3,7,11,23

Conjecture  - All prime numbers are odd

Counterexample - 2

→ 2 is a prime number but not odd, it is an even number.

Which table represents a linear functionWhich table represents a linear function
IceJOKER [234]

The table that has a constant average rate of change represents a linear function.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output of the function divided by the change in the input</u>.

When this rate is constant, the function is said to be linear, hence the table that has a constant average rate of change represents a linear function.

What is the rate of change (86, 124) (64, 113)
harkovskaia [24]
Hey there!

The rate of change for these two points would be m = 1/2. Subtract the two y points from each other and then the two x points from each other. Then you divide them. Or get a simplified fraction.

Hope this helped!

The distribution of the weights of loaves of bread from a certain bakery follows approximately a normal distribution. Based on a
artcher [175]

Answer:

μ=23.710740....

σ=3.592592....

Step-by-step explanation:

At first, we are told that it´s a normal distribution and the following:

P(x≤15.34)=0.1

P(x≤16.31)=0.2

We start looking for those values (0.1 and 0.2) and the probabilities that gives us those values in a normal standard distribution. There´s some tools that´ll help us out but i´ll be using a chart with the values of some probabilities in a normal standard distribution (That it´s attached).

The probability of P(z≤ a.b) where "a" is the whole part of a number and "b" the decimal part is in the coordinates (a,b). For example for our problem:

P(z≤-2.33)=0.099≈0.1

P(z≤-2.06)=0.197≈0.2

To find a probability of a normal (not standard) distribution we use a method called Normalize that proceeds:

P(x≤a)=P( (x-μ)/σ ≤ (a-μ)/σ )

Where μ is the Mean of the data and σ is the Standard deviation. P( (x-μ)/σ ≤ (a-μ)/σ ) is now part of a normal standard distribution and we are able to look for it in the chart.

We will use it to find the Mean and the STD for our distribution.

P(x≤15.34)=P(z≤-2.33)≈0.1

P(x≤16.31)=P(z≤-2.06)≈0.2

so we have the equations:

(15.34 - μ)/σ= -2.33 and (16.31 - μ)/σ= -2.06

And we solve them for μ and σ:

(15.34 - μ)/-2.33= σ and (16.31 - μ)/-2.06= σ

(15.34 - μ)/-2.33 = (16.31 - μ)/-2.06

2.06*(15.34 - μ) = 2.33(16.31 - μ)

2.33μ - 2.06μ = 2.33(16.31) - 2.06(15.34)

μ= 6.4019 / 0.27

μ= 23.710740...

With this value we find σ in one equation:

(15.34 - (23.710740...)/σ = -2.33

(15.34 - (23.710740...)/-2.33 = σ

σ=3.592592...

We finally have our answers:

μ=23.710740....

σ=3.592592....

2. Diego is solving the equation x2 - 12x = 18. Which value must be added to both sides of the equation to make the left side a
Ray Of Light [21]

You would need to subtract 18 to both sides to make this a perfect-square trinominal.

x^2 - 12x = 18

x^2 - 12x - 18 = 0

a = 1

b = -12

c = -18

Best of Luck!

Write down three integers, all less than 25, whose
ziro4ka [17]

Answer:

Our required integers will be 9,11,19.

Step-by-step explanation:

Let three integers all less than 25 be x,y,z

Since we have given that

Range = 10

Mean = 13

These three integers will be

Since their range is 10 i.e.

And Mean = 13
