The numbers that do not form a fact family are solved

Given data ,

A fact family consists of a set of related addition and subtraction facts that use the same numbers. For example, the numbers 3, 5, and 8 form a fact family because:

3 + 5 = 8

5 + 3 = 8

8 - 5 = 3

8 - 3 = 5

Numbers that do not form a fact family are any set of numbers that do not follow this pattern. For example, the numbers 2, 4, and 7 do not form a fact family because no combination of addition and subtraction using these numbers produces the other two numbers.

Answer:

one solution

Step-by-step explanation:

since the variables are only to a power of one, the options are no solutions, one solution, and infinitely many solutions.

using the distributive property, 10(x+4)= 10x + 40. simplify the equation 10x + 40 - 3 = 14x +1 to 10x + 37 = 14x + 1. move variables to one side and constants to another to get 4x = 36. divide to get x=6. so the answer is one solution

since we don't have something like 1=0 where two unequal constants are said to be equal, the answer isn't no solutions

since we dont have something like 1=1 where the two sides of the equation are equal no matter what x is, the answer isn't infinitely many solutions

Answer:

only one

x = 9

Step-by-step explanation:

how many solutions are in 10(x + 4) – 3 = 14x + 1

10(x + 4) – 3 = 14x + 1

10x + 40 - 3 = 14x + 1

-4x = 36

x = 9

only one

Step by step explanation:

The length vector is 1. So the sketch vector field f is given below. So the option a is correct.

In the given question, the vector field F by drawing a diagram like this figure.

The given vector field F is:

F(x, y) = (yi + xj)/√(x^2 + y^2)

We can write the vector field as:

F(x, y) = yi/√(x^2 + y^2) + xj/√(x^2 + y^2)

Here

F(x, y) = [y/√(x^2 + y^2)]^2 + [x/√(x^2 + y^2)]^2

F(x, y) = y^2/(x^2 + y^2) + x^2/(x^2 + y^2)

F(x, y) = (y^2+ x^2)/(x^2 + y^2)

F(x, y) = 1

F(0, y) = y/|y| = ±1

F(x, 0) = x/|x| = ±1

So the length vector is 1.

a. The continuous growth rate of the bacteria is 21%

b. The initial population of bacteria is 715

c. The culture will contain 2043 bacteria after 6 × 10⁻⁴ years

Since \(n(t) = 715e^{0.21t}\) represents the number of bacteria in the culture.

This function is similar to an exponential function of the form  \(y(t) = Ae^{\lambda t}\) where λ = growth rate

Comparing n(t) and y(t), we see that λ = 0.21

So, the continuous growth rate of the bacteria is 0.21 = 0.21 × 100 %

= 21%

So, the continuous growth rate of the bacteria is 21%

Since \(n(t) = 715e^{0.21t}\) represents the number of bacteria in the culture, the initial population of bacteria is obtained when t = 0.

So, \(n(t) = 715e^{0.21t}\)

\(n(0) = 715e^{0.21(0)} \\= 715e^{0} \\= 715 X 1\\= 715\)

So, the initial population of bacteria is 715

To find the time when the number of bacteria will be 2043, this means n(t) = 2043.

Since  \(n(t) = 715e^{0.21t}\)

Making t subject of the formula, we have

t = ㏑[n(t)/715]/0.21

So, substituting n(t) = 2043 into the equation, we have

t = ㏑[n(t)/715]/0.21

t = ㏑[2043/715]/0.21

t = ㏑[2.8573]/0.21

t = 1.05/0.21

t = 4.99

t ≅ 5 hours

Converting this to years, we have t = 5 h × 1 day/24h × 1 year/365 days

= 5/8760

= 5.7 × 10⁻⁴ years

≅ 6 × 10⁻⁴ years

So, the culture will contain 2043 bacteria after 6 × 10⁻⁴ years

The numerator of the repeated-measures t-statistic is the difference between the means of two related groups, while the numerator of the single sample t-statistic is the difference between the sample mean and the population mean.

In a repeated-measures t-test, you compare the means of two related groups, typically in a pretest-posttest design or when participants are measured under two different conditions. The numerator for the repeated-measures t-statistic is calculated as:

Numerator (Repeated-Measures) = Mean_Difference - 0

where Mean_Difference is the mean of the differences between the two related groups.

In a single sample t-test, you compare the mean of a single sample to a known population mean. The numerator for the single sample t-statistic is calculated as:

Numerator (Single Sample) = (Sample_Mean - Population_Mean)

In summary, the numerators differ in that the repeated-measures t-statistic considers the differences between two related groups, while the single sample t-statistic compares a sample mean to a population mean.

f(x) = 2x -3

Step-by-step explanation:

Looking at the graph

f(0) means when x =0 the value of y = ?

when x = 0 y = -3

f(1) means when x = 1  y = ?

When x = 1 y = -1

y increased from -3 to -1 so it increased by 2

Imani had 30 CDs on Monday.

Based on the given information, we can work backward to determine how many CDs Imani had on Monday.

On Thursday, there were 18 CDs left. This means that at the end of Wednesday, half of all the CDs that Imani had were destroyed. Therefore, the number of CDs she had on Wednesday was double the number left on Thursday, which is 18 CDs * 2 = 36 CDs.

On Tuesday, Imani bought six CDs. This means that before Tuesday, she had 36 CDs - 6 CDs = 30 CDs.

Therefore, based on this analysis, Imani had 30 CDs on Monday.

To summarize:

- Monday: 30 CDs

- Tuesday: Bought 6 CDs, total 30 + 6 = 36 CDs

- Wednesday: Half of the CDs destroyed, so 36 CDs / 2 = 18 CDs left

- Thursday: 18 CDs left

It is important to note that this analysis assumes that no CDs were added or removed between Monday and Tuesday, other than the six CDs that were bought. If there were any additional CDs involved, the calculation might differ.

By working backward from the given information and considering the events leading up to Thursday, we can determine that Imani had 30 CDs on Monday.
