Find the least common denominator of 1/6 and 11/9

The standard error of the mean is approximately 0.79 (rounded to two decimal places).

Define standard error ?

The standard error is a statistical term that measures the variability of a sample mean or an estimate of a population parameter from its true value. It is the standard deviation of the sampling distribution of the mean. In simpler terms, the standard error measures how much the sample mean varies from the true population mean. A smaller standard error indicates that the sample mean is more likely to be representative of the population mean, while a larger standard error suggests that the sample mean may not be as reliable.

The formula for the standard error of the mean is:

[tex]SE = \frac{\sigma }{\sqrt{n}}[/tex]

Where σ is the population standard deviation and n is the sample size.

Substituting the given values:

[tex]SE =\frac{5}{\sqrt{40}}[/tex]

SE ≈ 0.79

Therefore, the standard error of the mean is approximately 0.79 (rounded to two decimal places).

Define Algebraic Expression

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it. In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

Given expression,

-2/9 x=2/5

Isolate the variable, x

x = (2 * 9) / ( 5 * -2)

x = - (9/5) or -1 4/5

Hence, the value of x is -1 4/5 i.e, option(A)

The value of x for the given triangle is 2 units.

According to the question,

We have the following information:

We have a figure of triangle where a line segment is dividing the two sides. The measurement of some of its sides are given.

Now, the side with measurement 12 units and one divided side is 4 units.

The next side to 4 units in the same side will be (12-4) units or 8 units.

Now, using the basic proportionality theorem, we have the following expression:

6/6x = 4/8

Using the cross multiplication method:

6x*4 = 8*6

x = 48/24

x = 2 units

Hence, the value of x for the given triangle is 2.

Answer:-4<x<=5

Step-by-step explanation:

The white dot is above -4 and the filled in dot is above 5. Put that together plus the correct inequality signs and you get -4<x<=5

Answer: [tex]-4 < x\leq 5[/tex]

Step-by-step explanation:

The inequality ends at 4 and it is colored white so x must be greater than -4 therefore the first expression is x > -4 or -4 < x.

The other side of the inequality ends at 5 and it's colored black so x is less than or equal to 5. Therefore the second expression is [tex]x\leq 5[/tex].

if we merge the two equations together than we would get [tex]-4 < x\leq 5[/tex].

Answer:

1/18

Step-by-step explanation:

Since x=2/3, we can plug in 2/3 for x, and we have 2/3 divided by 12.

Based on what we know about fractions, we can say that dividing by 12 is the same as multiplying by 1/12.

Therefore, we have the expression 2/3*1/12.

Next, we get 2/36, which can be simplified into 1/18.

p(t) = 6000·(1/2)^(t/3) is the exponential function which represents the size of the bacteria.

What is bacteria?

Bacteria are common, mostly non-symbiotic organisms that regularly solely have one biological cell. they create up a big portion of the being microorganism kingdom.

Main Body:

An exponential growth or decay can be modeled by =

value = (initial value) · (growth factor)^(t/(time for growth factor))

Here, the growth factor is 3000/6000 = 1/2 in 3 hours. The initial value is 6000. Putting those numbers into the above form, we have ...

p(t) = 6000·(1/2)^(t/3)

If you prefer your exponential functions to be a power of e, then this is ... Hence,p(t) = 6000·e^(-0.23105t)

The constant -0.23105 is ln(1/2)/3.

Answer:

it is called horizon simple question simple answer

Answer:

Step-by-step explanation:

The correct answer is:

|w-20| ≤ 0.12.

Explanation:

We first find the average of the two ends of the inequality:

(19.88+20.12)/2 = 40/2 = 20

This will be the number subtracted from w in the inequality.

Now we find the difference between this value and the ends:

20-19.88 = 0.12

20.12 - 20 = 0.12

This will be what our absolute value inequality ends with; the "answer" part, so to speak.

Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."

This gives us

|w-20| ≤ 0.12

Martin will have more-money than his friend after babysitting for 10 hours

The given parameters in the question are:

Martin

Initial amount = $30

Additional earnings = $10

His friend

Initial amount = $60

Additional earnings = $7

The equation that shows their total earnings is

y = Initial amount + Additional earnings * x

So, we have

Martins: y = 30 + 10x

His friend: y = 60 + 7x

When Martin has more money, we have

Martins > His friend

This gives

30 + 10x > 60 + 7x

Evaluate the like terms in the above inequality

3x > 30

Divide by 3

x > 10

Hence, Martin will have more money after 10 hours

2. 2(4x − 2) = 10x – 6  x=1

3. 7+x=2x+6    x=1

4. 2x+2=-2(1-x)   No Solution

Hope this helps

Answer:

Step-by-step explanation:

2(6 + 4x) = 8x + 6

12 + 8x = 8x +6

12 -6 + 8x = 8x + 6 -6

6 + 8x = 8x

6 + 8x - 8x = 8x -8x

6 = 0

no solution

2(4x -2) = 10x -6

8x -4 = 10x -6

8x - 4 +4 = 10x -6 +4

8x = 10x - 2

8x - 10x = 10x -10x -2

-2x = -2

-2x/-2 = -2 /-2

x = 1

7 + x = 2x +6

7 -6 + x = 2x +6 -6

1 + x = 2x

1 + x -x = 2x -x

1 = x

2x + 2 = 2(1 - x)

2x + 2 = 2 - 2x

2x +2 -2 = 2 -2 - 2x

2x = -2x

2x + 2x = -2x + 2x

The addition or subtraction of a constant to a function will change its position in the cartesian plane. Depending on the sign of the constant, it can shift upwards or downwards.

Let a quadratic function be f(x) = 2x^2.

Let c be the positive constant.

It is now necessary to determine what will happen if we add or subtract a constant to the function.

The function f(x) = 2x^2 is a parabola opening upwards.

Now, if we add the positive constant c, then the graph of the function will shift upwards by c units and nothing will change. If we subtract the positive constant c, then the graph of the function will shift downwards by c units.

Thus, the addition or subtraction of a constant to a function will change its position in the cartesian plane. Depending on the sign of the constant, it can shift upwards or downwards.

Given,

Here we have the points (1, -2).

Now, we have to translate this point by left side by 4 point.

In order to translate the given point we have to take the value of the x coordinate and then we have to subtract the translation point from it,

So, the calculation for this one is look like

Here the value of the x coordinate is 1

Answer:

  (b)  -16

Step-by-step explanation:

You want the y-value that goes with x=17 on the line with slope -8/9 through point (-19, 16).

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

The line with slope -8/9 through point (-19, 16) will have the equation ...

  y -16 = -8/9(x +19)

You want the value of y for x=17. We can find that by substituting x=17 into the above equation:

  y -16 = -8/9(17 +19) = -8/9(36) = -32

Adding 16 gives the value of y:

  y = 16 -32 = -16

The line passes through the points (-19, 16) and (17, -16).
