The margin of error can be calculated using the formula:
Margin of error = (upper limit of the confidence interval - lower limit of the confidence interval) / 2

In this case, a margin of error of 9.55 suggests that the sample mean is quite precise, since it's relatively close to the true population mean (which we know to be 52.90).

In this case, the lower limit of the confidence interval is 43.85 and the upper limit is 61.95.
Margin of error = (61.95 - 43.85) / 2
Margin of error = 9.55
Therefore, the margin of error is 9.55. This means that if the sample size were to be repeated, we would expect the sample mean to be within 9.55 units of the true population mean 95% of the time.
It's worth noting that the confidence interval provides a range of values within which we can be reasonably certain that the true population mean lies. The margin of error, on the other hand, gives us an indication of the precision of our estimate. However, if the margin of error were larger, this would indicate that our estimate is less precise and that we need a larger sample size to obtain a more accurate estimate of the population mean.

Answer:

Angle A: 30°

Angle B: 60°

Angle C: 90°

Step-by-step explanation:

Hopefully this helps! :)

The measure of the interior angles are Angle A: 30°, Angle B: 60° and Angle C: 90°

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

The given triangle has angle measurements of 30º and 90° which is given in the question.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

∵ The sum of the interior angles in the triangle = 180°

So the measure of the remaining angle would be x:

⇒ 30° + 90°  + x = 180°

⇒ x = 180 - 30° - 90°

⇒ x = 180 - 120°

⇒ x = 60°

Therefore, the required measure of the remaining angle x is 60°.

Based on the study results, there appears to be a difference among North American, European, and Asian organizations in the proportion of organizations that raised prices in response to unfavourable exchange rates.

Out of the surveyed sample, 46.67% of North American organizations (70 out of 150) raised prices, while 54.17% of European organizations (65 out of 120) and 30% of Asian organizations (30 out of 100) raised prices. Therefore, it can be concluded that a higher proportion of European organizations raised prices compared to North American organizations, while Asian organizations had the lowest proportion.

Answer:

length = 14cm width = 7cm

Step-by-step explanation:

length = 2x w (width)

if length = 2x width then

length must equal 4/6 and width must equal 2/6 because length is 2 times width.

42 divded by 6 = 7.

length gets four lots of 7.

length of both sides= 28cm

width gets 2 lots of 7.

width of both sides= 14cm

there are two sides for length and two sides for width.

Length x 2= 28cm

Length must equal 14cm.

Width x 2 = 14cm

Width must equal 7cm.

lets just prove this is true:

7+7=14.

14+ (14+14) =

14+ 28= 42cm.

this works.

the length is 14cm and the width is 7cm.

Answer:

Length = 14 cm

  width = 7 cm

Step-by-step explanation:

given:

rectangle

where    L = 2W

             W = W

Perimeter = 42 cm

find: Length of L

solution:

Perimeter or a rectangle = 2L + 2W

plugin the given values into the formula:

42 = 2(2W) + 2W

42 = 4W +2W

42 = 6W

W = 42/6

W = 7 cm (width of Rectangle)

solve L by using  substituting W=7 in L = 2W

L = 2W

L = 2 (7)

L = 14 cm

therefore, the Length = 14 cm

                          width = 7 cm

Answer:

The circle one

Step-by-step explanation:

What you need to do is count the number of squares or slices it has and then count how Buchanan the chunk is divided into, should be 6

==============================================================

Explanation:

Ignore the dashed smaller lines for now. The solid black vertical lines form 4 smaller equal pieces, and not 5. Each tickmark represents 1/4 and not 1/5

So if you wanted to represent a model for \(\frac{1}{4}\div 6\), then you would use the lower left corner. However, we want that 1/4 to be 1/5 instead. So this is why the answer is the lower left corner.

Everything else is a correct model. We started dividing everything into 5 equal parts. Then we focused on one of those slices, and subdivided that slice into 6 equal parts. Imagine doing that for each slice and we should have 5*6 = 30 smaller pieces total. Hence \(\frac{1}{5} \div 6 = \frac{1}{5} \times \frac{1}{6} = \frac{1}{30}\)

Step-by-step explanation:

Given that:

X = time taken to complete mathematics homework

Y= time taken to complete language homework

Standard deviation of X ; SD(X) = 3

Standard deviation of Y ; SD(Y) = 4

rho = - 0.375

rho = Cov(X, Y) / SD(X) * SD(Y)

-0.375 = COV(X, Y) / 3 * 4

COV(X, Y) = 12 * - 0.375

COV(X,Y) = - 4.5

Variance(X, Y) = V(X, Y)

V(X, Y) = V(X) + V(Y) + 2COV(X,Y)

V(X) =SD(X)² = 3² = 9

V(Y) = SD(Y)² = 4² = 16

V(X,Y) = 9 + 16 + 2(-4.5)

V(X, Y) = 16

SD(X, Y) = sqrt(V(X, Y)) = sqrt(16) = 4

Hence, standard deviation to complete entire homework, SD(X, Y) = 4

How to calculate percentage and how is it determined?
A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it. No dimension exists for percentages. Thus, it is referred to as a dimensionless number. The value must be divided by the entire value, and the resulting number must then be multiplied by 100 to get the percentage.
Mathematically, Percentage formula = (Value/Total value) × 100

Given, cost price of hat (total value) = $ 15.99
Percentage tax imposed on the hat = 6%
Now, using the formula established in the literature above, we have:
Percentage = (Value/Total Value)×100
⇒ Value = (Percentage × Total Value)/100 = (6×15.99)/100 = $ 0.9594
Therefore, the total price of hat = Cost Price + Value = $ (15.99 + 0.9594) = $ 16.9494
Thus, the total price of the hat including the tax is $ 16.9494 .

The length of IKE is 2x - 12.

A condition on a variable that is true for just one value of the variable is called an equation.

Since KITE is a kite, we know that KT = IT and KE = IE. Let's call the length of these diagonals d. Then we have:

KT + TI = d

KE + EI = d

Substituting in the given values, we get:

x + 6 + 2x = d

2x + IE = d

Solving for d in the first equation, we get:

3x + 6 = d

Substituting this into the second equation, we get:

2x + IE = 3x + 6

Solving for IE, we get:

IE = x + 6

Therefore, IKE is equal to:

IKE = IT - IE

IKE = (d - KT) - (x + 6)

IKE = (3x + 6 - x - 6) - (x + 6)

IKE = 2x - 12

So, the length of IKE is 2x - 12.

You know a cube has 6 sides, so you divide 24 by 6 to get the surface area of 1 side

24/6 = 4

To get the volume, multiply the base (4) by the height (2)

Answer:

V = 126 cm³

Step-by-step explanation:

the figure is made up of 2 cuboids ( flat one on the left and upright one on the right )

the volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth, h is height )

cuboid on left has l = 7 , b = 6 and h = 1 , then

V = 7 × 6 × 1 = 42 cm³

upright cuboid has l = 7 , b = 3 and h = 4 , then

volume = 7 × 3 × 4 = 84 cm³

Then volume of figure is the sum of the 2 volumes calculated

V = 42 + 84 = 126 cm³

Answer:

126 cm^3

Step-by-step explanation:

In order to find the volume of a cuboid the formula is:

l × w × h

In this case, we actually have two cuboids making up this one figure. Thus you can them apart into two cuboids.

I take one cuboid with the measurements of 9 by 7 by 3 and calculate the volume below:

\(9*7*3=63\)

Similarly, the other cuboid will have measurements of 3 by 3 by 7(the reason why h is 3 is that I chose to include the bottom half of the width of the cuboid). Now calculate your volume for the second cuboid:

\(3*3*7=63\)

Now add both volumes together and you  get 126 cm^3

What is function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

Main body:

Function representing the level of water by 'y' and number of hours by 'x' is,

y = 2.5 cos (2πx/12.5)+12

For y = 12 meters, (Substitute the value of y)

12 = 2.5 cos (2πx/12.5)+12

12 -12 = 2.5 cos (2πx/12.5)

cos (2πx/12.5) = 0

2πx/12.5 = π/2

πx/12.5 = π/4

x = 3.125

x ≈3.1 hours
