Which fraction is equal to 0.7 repeating

For the x-bar chart, the upper control limit is 19.15 and the lower control limit is 12.87; for the R-chart, the upper control limit is 10.17 and the lower control limit is 0.43.

To calculate the control limits for the x-bar (sample mean) chart and the R-chart (sample range) chart, we need to use statistical formulas based on the sample size and the average values.

For the x-bar chart:

Calculate the standard deviation (σx-bar) of the sample means using the formula σx-bar = σ / √n,

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

Calculate the control limits for the x-bar chart using the formula:

Upper Control Limit (UCL) = x-bar + A2 \(\times\) σx-bar

Lower Control Limit (LCL) = x-bar - A2 \(\times\) σx-bar

Here, A2 is a constant depending on the sample size and the desired level of control. For a sample size of 5, A2 is typically 0.577.

For the R-chart:

Calculate the control limits for the R-chart using the formula:

Upper Control Limit (UCL) = D4 \(\times\) R

Lower Control Limit (LCL) = D3 \(\times\) R

Here, D3 and D4 are constants depending on the sample size. For a sample size of 5, D3 is 0 and D4 is typically 2.115.

Given the information provided, we can calculate the control limits as follows:

Calculate σx-bar = σ / √n = σ / √5.

Calculate the x-bar chart limits:

UCL (x-bar) = x-bar + 0.577 \(\times\) σx-bar

LCL (x-bar) = x-bar - 0.577 \(\times\) σx-bar

Calculate the R-chart limits:

UCL (R) = 2.115 \(\times\) R

LCL (R) = 0 \(\times\) R (which is 0)

Please note that the population standard deviation (σ) is not provided, so we cannot calculate the exact control limits without that information.

Answer:

the time taken for having 1 million bacteria is 137.68 hours  

Step-by-step explanation:

The computation is shown below:

y = 2 × (1.10)^x

1,000,000 = 2 × (1.10)^x

500,000 = (1.10)^x

x = log (500,000) ÷ log (1.10)

= 137.68 hours

hence the time taken for having 1 million bacteria is 137.68 hours  

The length of the median = 6\(\sqrt{3}\)

If we call the longer base "a" and the shorter base "b", then we know that:

a:b = 2:1

Since the ratio of the four sides is 1:1:1:1, we know that the height, median and the longer base are all equal.

We can use that information to determine the area of the trapezoid. The formula for the area of a trapezoid is:

Area = (a + b) * h / 2

We know that the area is  27\(\sqrt{3}\) and the height and median are equal, so we can set up the equation:

(a + b) * h / 2 = 27\(\sqrt{3}\)

We also know that a:b = 2:1, so we can substitute that in:

(2b + b) * b / 2 = 27\(\sqrt{3}\)

Simplifying, we get:

3b^2 = 54 * \(\sqrt{3}\)

So the length of the median (h) is b

= \(\sqrt{(54 * \sqrt{3} / 3) }\)

= 6\(\sqrt{3}\)

Answer:

13*

Step-by-step explanation:

Use the Pythagorean theorem.

a=1

b=x

c=13

so, \(1^2 + x^2 = 13^2\)

\(x^2 = 169 - 1 = 168\)

\(x = \sqrt{168}\)

 \(\sqrt{168} = 12.961481396815720461931934872176\) = 13

*If we round to the nearest tenth, we get 13. Because of this rounding, the other leg is the hypotenuse, but it is actually different.

The orthogonal projection of vector v onto the subspace spanned by u₁ and u₂ is (-1/18, 1/18, 19/18).

What is vector?

A vector is a mathematical object that represents both magnitude and direction. It is commonly represented as an ordered set of numbers, known as components or coordinates, arranged in a specific order.

To find the orthogonal projection of vector v onto the subspace spanned by vectors u₁ and u2, we can use the formula:

proj_w(v) = ((v · u₁) / (u₁ · u₁)) * u₁ + ((v · u₂) / (u₂ · u₂)) * u₂

where "·" represents the dot product.

First, let's calculate the dot products and the norms squared:

v · u₁ = 12 + 2(-2) + 41 = 2 - 4 + 4 = 2

u₁ · u₁ = 22 + (-2)(-2) + 11 = 4 + 4 + 1 = 9

v · u₂ = 1 * (-1) + 21 + 44 = -1 + 2 + 16 = 17

u₂ · u₂ = (-1)(-1) + 11 + 4 * 4 = 1 + 1 + 16 = 18

Now, we can substitute these values into the formula:

\(\rm proj_w\)(v) = (2/9) * u₁ + (17/18) * u₂

To simplify further, we can perform scalar multiplication:

\(\rm proj_w\)(v) = (2/9) * (2, -2, 1) + (17/18) * (-1, 1, 4)

\(\rm proj_w\)(v) = (4/9, -4/9, 2/9) + (-17/18, 17/18, 17/9)

Combining like terms:

\(\rm proj_w\)(v) = (4/9 - 17/18, -4/9 + 17/18, 2/9 + 17/9)

\(\rm proj_w\) (v) = (-1/18, 1/18, 19/18)

Therefore, the orthogonal projection of vector v onto the subspace spanned by u₁ and u₂ is (-1/18, 1/18, 19/18).

Step-by-step explanation:

It will take 3 hours to bake 3 pans of baked macaroni if the oven can only bake one pan of baked macaroni for 1 hour.

If Jeanna's oven can only bake one pan of baked macaroni for 1 hour, then it will take 3 hours to bake 3 pans of baked macaroni. This is because the time it takes to bake the pans is directly proportional to the number of pans being baked. Therefore, if it takes 1 hour to bake 1 pan, it will take 3 hours to bake 3 pans. So, the answer is 3 hours.

It is important to note that the number of pans Jeanna wishes to bake, which is 34 pans, is irrelevant to the question. The question only asks for the time it will take to bake 3 pans of baked macaroni, so the number of pans Jeanna wishes to bake does not affect the answer.

The  probability of event A is P(A) = 1/4 or 0.25.

The formula to find P(A) for a series of simple events is:

P(A) = (number of outcomes that satisfy the event A) / (total number of possible outcomes)

For example, if you are tossing a coin and selecting a number at the same time, and event A is defined as getting a head and an even number, then:

- The number of outcomes that satisfy event A is 1 (getting a head and an even number, i.e., H2)
- The total number of possible outcomes is 4 (H1, H2, T1, T2)
- Therefore, the probability of event A is P(A) = 1/4 or 0.25.

To find the average cost of producing 400 units of plywood, we need information about the cost function. If we have the cost function per unit, we can calculate the total cost of producing 400 units and then divide it by 400 to find the average cost per unit.

Let's assume the cost function for producing x units of plywood is given by C(x), where C(x) represents the cost in dollars. We can then calculate the total cost of producing 400 units as follows:

Total Cost = C(x) * Number of Units

Total Cost = C(400) * 400

Once we have the total cost, we can find the average cost per unit by dividing the total cost by the number of units:

Average Cost per Unit = Total Cost / Number of Units

Average Cost per Unit = (C(400) * 400) / 400

Average Cost per Unit = C(400)

Therefore, to find the average cost of producing 400 units, we need to know the cost function C(x) specifically for producing 400 units of plywood. Without that information, we cannot provide an exact value for the average cost.

3x - 9y = 9 → (1)

- 2x +2y = 8 ( subtract 2y from both sides )

- 2x = - 2y + 8 ( divide through by - 2 )

x = y - 4

substitute x = y - 4 into (1)

3(y - 4) - 9y = 9

3y - 12 - 9y = 9

- 6y - 12 = 9 ( add 12 to both sides )

- 6y = 21 ( divide both sides by - 6 )

y = \(\frac{21}{-6}\) = - \(\frac{7}{2}\)

1) From the given line segments, it is clear that XM is congruent to YM since M bisects XY. Thus;

XM = YM and XM + YM = XY

We are given that;

XM = 3x + 1

YM = 8x - 24

Thus;

3x + 1 = 8x - 24

8x - 3x = 1 + 24

5x = 25

x = 25/5

x = 5

Thus;

XM = 3(5) + 1 = 16

YM = 8(5) - 24 = 16

XY = 16 + 16 = 32
