Answer:

The 99% confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company is between 11.01 years and 12.55 years.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.005 = 0.995[/tex], so [tex]z = 2.575[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.575*\frac{3.2}{\sqrt{114}} = 0.77[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 11.78 - 0.77 = 11.01 years

The upper end of the interval is the sample mean added to M. So it is 11.78 + 0.77 = 12.55 years

The 99% confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company is between 11.01 years and 12.55 years.

The true statements include

The equation is given as:

2l + 2w = 62

Where:

l = 20

Substitute l = 20

2 * 20 + 2w = 62

Evaluate

40 + 2w = 62

Subtract 40 from both sides

2w = 22

Divide both sides by 2

w = 11

The above computation means that the true statements include (c), (d) and (e)

Given:

The given table represents the ingredient need to make 4 muffins.

To find:

The amount of flour needed to make 12 muffins.

Solution:

We have, the data for 4 muffins.

From the given table it is clear that,

Flour need for 4 muffins = 250 g

Flour need for 1 muffins = [tex]\dfrac{250}{4}[/tex] g

Flour need for 12 muffins = [tex]\dfrac{250}{4}\times 12[/tex] g

                                          = [tex]250\times 3[/tex] g

                                          = [tex]750[/tex] g

So, 750 g flour is need to make 12 muffins.

Therefore, the correct option is D.

Answer: 750

Step-by-step explanation: If The recipe for four muffins calls for 250g of flour if you multiply 250 by 3 get the answer wich is 750

As we know that,

Pythagoras triplet

1) a² + b² = c²

Let

[tex]\sf \: {2}^{2} + {2}^{2} = {4}^{2}[/tex]

[tex]\sf \: 4 + 4 = 16[/tex]

2) a² + b² = c²

[tex]\sf \:5 {}^{2} + {12}^{2} = {13}^{2}[/tex]

[tex]\sf \: 25 + 144 = 169[/tex]

3)a² + b² = c²

[tex]\sf {3}^{2} + {5}^{2} = {6}^{2}[/tex]

[tex]\sf 9 + 25 = 36[/tex]

4) a² + b² = c²

[tex]\sf {5}^{2} + {4}^{2} = {7}^{2}[/tex]

[tex]\sf \: 25 + 16 = 49[/tex]

Only B can be Pythagoras triplet.

just did mental math, not sure if it's the right way

Answer:

It's a whole number. It cannot be a mixed number. Anyways I would have to know the denominator.

The roof top would be 0. At 12 seconds the ball is at -225.6, which would be the ground so the building would be 225.6 meters tall.

The highest positive value is 81.6, so this is the highest the ball goes up.

The value changes from a positive to a negative between 8 and 10, which means that would be around the time it is the same height as the building.

The answers would be:

It's an equilateral triangle, all angles are congruent.

Step-by-step explanation:

5.) f(1) = 7, f(n) = -4※f(n-1) + 15

[tex]f(2) = - 4 \times 7 + 15 = - 13 \\ f(3) = - 4 \times ( - 13) + 15 = 67 \\ f(4) = - 4 \times 67 + 15 = - 253[/tex]

The first four terms are 7, -13, 67, -253.

7.) f(1) = 3, f(n) = [f(n-1)]²

[tex]f(2) = (3)^{2} = 9 \\ f(3) = ( {9)}^{2} = 81 \\ f(4) = ( {81)}^{2} = 6561[/tex]

The first four terms are 3, 9, 81, 6561.

Step-by-step explanation:

Answer:

218 adults and 104 children attended.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=322 (1)

8.75x+6y=2531.50 (2), where:

x is the number of adults

y is the number of children

First, you can solve for x in (1):

x=322-y (3)

Then, you can replace (3) in (2) and solve for y:

8.75(322-y)+6y=2531.50

2817.5-8.75y+6y=2531.50

2817.5-2531.50=8.75y-6y

286=2.75y

y=286/2.75

y=104

Finally, you can replace the value of y in (3) to find x:

x=322-104

x=218

According to this, the answer is that 218 adults and 104 children attended.
