Answer:

The factors that cause Earth to experience seasons are:

1. the tilt of Earth’s axis

2. the directness of the Sun’s rays

The factors that cause Earth to experience seasons are:

1. the tilt of Earth’s axis

2. the directness of the Sun’s rays

The reason why the Earth contains various seasons because it deals with the variation of the sun's rays angles and the earth titles to the 23.5 degrees on its axis. Also along with the earth rotation, the earth orbits should be around to the sun because of which various parts should be exposed to the different amount of lights

Therefore, the above two points should be considered.

Given Information:

Occupancy rate of Ginger’s hotel = 85%

Competitive set available rooms = 150,000

Competitive set sold rooms = 115,000

Required Information:

Occupancy rate INDEX = ?

Answer:

Occupancy rate INDEX = 111%

Step-by-step explanation:

The occupancy rate INDEX is given by

Occupancy rate INDEX = Occupancy rate of Ginger’s hotel/Occupancy  rate of competitive set

We are given the occupancy rate of Ginger’s hotel so we need to first find out occupancy  rate of competitive set which is given by

Occupancy rate of competitive set = Competitive set sold rooms/Competitive set available rooms

Occupancy rate of competitive set = 115,000/150,000

Occupancy rate of competitive set = 0.7667

Occupancy rate of competitive set ≈ 76.67%

Finally, we can now find the occupancy rate INDEX

Occupancy rate INDEX = Occupancy rate of Ginger’s hotel/Occupancy rate of competitive set

Occupancy rate INDEX = 85/76.67

Occupancy rate INDEX = 1.108

Occupancy rate INDEX = 110.8%

Occupancy rate INDEX ≈ 111%

Therefore, the approximate occupancy rate INDEX last month for Ginger's hotel is 111%

The best-predicted pulse rate for a woman who is 66 inches tall, using the given regression equation 18.4 + 0.930x, is approximately 79.78 beats per minute.

To predict the pulse rate of a woman who is 66 inches tall using the given regression equation, we plug in the height (x = 66) into the equation:

ModifyingAbove y with caret = 18.4 + 0.930x

Substituting x = 66:

ModifyingAbove y with caret = 18.4 + 0.930(66)

Perform the calculation:

ModifyingAbove y with caret = 18.4 + 61.38

ModifyingAbove y with caret = 79.78

Therefore, the best-predicted pulse rate for a woman who is 66 inches tall is approximately 79.78 beats per minute. This prediction assumes that the relationship between height and pulse rate holds for this particular height value.

System of hypothesis  

We want to check if the mean pressure is less then 7.6 pounds/square inch, the system of hypothesis are:  

Null hypothesis:[tex]\mu \geq 7.6[/tex]  

Alternative hypothesis:[tex]\mu < 7.6[/tex]  

The statistic would be:

If the calculated value is less than the critical value we reject the null hypothesis.

P value

The p value for this test would be:

Answer:

Total no  of different ways can the 4 computers be chosen  = 70

Step-by-step explanation:

Given -

A computer retail store has 8 personal computers in stock.A buyer wants to purchase 4 of them.

(Using the combination formula)

The combination of n events taking r at a time = [tex]\mathbf{\binom{n}{r}}[/tex]

where n = 8 and r = 4

Total no  of different ways can the 4 computers be chosen = [tex]\mathbf{\binom{8}{4}}[/tex]

    =  [tex]\boldsymbol{\frac{8!}{(4!)(4!)}}[/tex]

=   70

The number of different ways that 4 computers can be chosen from a stock of 8 is 70.

The number of different ways that 4 computers can be chosen from a stock of 8 is determined by the concept of combinations. In this case, we want to find the number of combinations of 8 items taken 4 at a time. The formula for combinations is given by:

C(n, r) = n! / r!(n-r)!

where n is the total number of items and r is the number of items to be chosen. Applying the formula to this problem, we have:

C(8, 4) = 8! / 4!(8-4)!

Simplifying the expression, we get:

C(8, 4) = 8! / 4!4!

Using the factorial function, we can compute:

C(8, 4) = 8 × 7 × 6 × 5 / (4 × 3 × 2 × 1)

C(8, 4) = 70

Therefore, there are 70 different ways that the 4 computers can be chosen from the stock of 8.

Answer:

It takes 3 seconds for the diver to reach the water.

Step-by-step explanation:

The height, in feet, is given by the following equation:

[tex]h(t) = -16t^{2} + 144[/tex]

How many seconds will it take for the diver to reach the water?

He reaches the water when his height is 0, that is, when h(t) = 0. So

[tex]h(t) = -16t^{2} + 144[/tex]

[tex]0 = -16t^{2} + 144[/tex]

[tex]16t^{2} = 144[/tex]

[tex]t^{2} = \frac{144}{16}[/tex]

[tex]t^{2} = 9[/tex]

[tex]t = \pm \sqrt{9}[/tex]

[tex]t = \pm 3[/tex]

There are no negative instant of time, so just t = 3.

It takes 3 seconds for the diver to reach the water.

(d) The particle moves in the positive direction when its velocity has a positive sign. You know the particle is at rest when [tex]t=0[/tex] and [tex]t=3[/tex], and because the velocity function is continuous, you need only check the sign of [tex]v(t)[/tex] for values on the intervals (0, 3) and (3, 6).

We have, for instance [tex]v(1)\approx-0.91<0[/tex] and [tex]v(4)\approx0.91>0[/tex], which means the particle is moving the positive direction for [tex]3<t<6[/tex], or the interval (3, 6).

(e) The total distance traveled is obtained by integrating the absolute value of the velocity function over the given interval:

[tex]\displaystyle\int_0^6|v(t)|\,\mathrm dt=\int_0^3-v(t)\,\mathrm dt+\int_3^6v(t)\,\mathrm dt[/tex]

which follows from the definition of absolute value. In particular, if [tex]x[/tex] is negative, then [tex]|x|=-x[/tex].

The total distance traveled is then 4 ft.

(g) Acceleration is the rate of change of velocity, so [tex]a(t)[/tex] is the derivative of [tex]v(t)[/tex]:

[tex]a(t)=v'(t)=-\dfrac{\pi^2}9\cos\left(\dfrac{\pi t}3\right)[/tex]

Answer:

a) 54 mph to 144 mph

Step-by-step explanation:

We don't know the shape of the distribution, so we use Chebyshev's Theorem to solve this question. It states that:

At least 75% of the measures are within 2 standard deviations of the mean.

At least 89% of the measures are within 3 standard deviations of the mean.

At least eight-ninths of the player's serves.

8/9 is approximately 89%

So

Mean: 99, standard deviation: 15

99 - 3*15 = 54

99 + 3*15 = 144

So the correct answer is:

a) 54 mph to 144 mph

[tex]p_v =P(z>1.82)=0.034[/tex]  

Assuming a standard significance level of [tex]\alpha=0.05[/tex] the best conclusion for this case would be:

4. There is not enough evidence to show that more than 35% of community college students own a smart phone (P-value = 0.034).

Because [tex] p_v <\alpha[/tex]

If we select a significance level lower than 0.034 then the conclusion would change.

Step-by-step explanation:

Data given

n=300 represent the random sample taken

X=120 represent the people who have a smart phone

[tex]\hat p=\frac{120}{300}=0.4[/tex] estimated proportion of people who have a smart phone

[tex]p_o=0.35[/tex] is the value that we want to test

z would represent the statistic (variable of interest)

[tex]p_v[/tex] represent the p value (variable of interest)  

System of hypothesis

We need to conduct a hypothesis in order to test the claim that the true proportion of people who have a smart phone is higher than 0.35, the system of hypothesis are.:  

Null hypothesis:[tex]p\leq 0.35[/tex]  

Alternative hypothesis:[tex]p > 0.35[/tex]  

The statistic is given by:

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

Calculate the statistic  

Since we have all the info requires we can replace in formula (1) like this:  

[tex]z=\frac{0.4 -0.35}{\sqrt{\frac{0.35(1-0.35)}{300}}}=1.82[/tex]  

Statistical decision  

Since is a right tailed test the p value would be:  

[tex]p_v =P(z>1.82)=0.034[/tex]  

Assuming a standard significance level of [tex]\alpha=0.05[/tex] the best conclusion for this case would be:

4. There is not enough evidence to show that more than 35% of community college students own a smart phone (P-value = 0.034).

Because [tex] p_v <\alpha[/tex]

If we select a significance level lower than 0.034 then the conclusion would change.

Answer:

84.13% of bottles will have volume greater than 994 mL

Step-by-step explanation:

Mean volume = u = 1000

Standard deviation = [tex]\sigma[/tex] = 6

We need to find the proportion of bottles with volume greater than 994. So our test value is 994. i.e.

x = 994

Since the data is normally distributed we will use the concept of z-score to find the required proportion. First we convert 994 to its equivalent z-score, then using the z-table we will find the corresponding value of proportion. The formula to calculate the z score is:

[tex]z=\frac{x-u}{\sigma}[/tex]

Substituting the values, we get:

[tex]z=\frac{994-1000}{6}=-1[/tex]

This means 994 is equivalent to a z score of -1. Now we will find the proportion of z values which are greater than -1 from the z table.

i.e. P(z > -1)

From the z-table this value comes out to be:

P(z >- 1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413

Since, 994 is equivalent to a z score of -1, we can write that proportion of values which will be greater than 994 would be:

P( X > 994 ) = P( z > -1 ) = 0.8413 = 84.13%

To find the proportion of bottles with more than 994 mL, calculate the z-score and use a z-table. Approximately 93.32% of bottles are filled with more than 994 mL.

To determine the proportion of bottles with volumes greater than 994 mL, we need to use the properties of the standard normal distribution. The mean volume of a bottle is given as 1000 mL with a standard deviation of 4 mL. We first calculate the z-score for 994 mL, which is the number of standard deviations 994 mL is from the mean.

Z = (X - μ) / σ = (994 mL - 1000 mL) / 4 mL = -1.5

Using a z-table or standard normal distribution calculator, we can find the proportion of the area to the right of z = -1.5, which represents the proportion of bottles filled with more than 994 mL. The area to the right of z = -1.5 is approximately 0.9332. Therefore, about 93.32% of the bottles are expected to have volumes greater than 994 mL.

Answer:

We accept H₀ we don´t have enough evidence to conclude that a consumer group position is correct

Step-by-step explanation:

We have a case of test of proportion, as a consumer group is suspicious of the claim and think the proportion is lower we must develop a one tail test (left tail) Then

1.- Test hypothesis:

Null hypothesis  H₀                   P = P₀

Alternative hypothesis  Hₐ       P < P₀

2.- At significance level of α  = 0,05   Critical value

z(c)  =  -1,64

3.-We compute z(s) value as:

z(s)  =  ( P - P₀ )/ √P*Q/n      where   P = 44/80     P = 0,55   and Q = 0,45

P₀ = 0,6   and  n = 80

Plugging all these values in the equation we get:

z(s)  = ( 0,55 - 0,6 ) / √(0,2475/80)

z(s)  =  - 0,05/ √0,0031

z(s)  =  - 0,05/0,056

z(s)  =  - 0,8928

4.-We compare  z(s)  and  z(c)

z(s) > z(c)      -0,8928 on the left side it means that z(s) is in the acceptance region so we accept H₀

Answer:

It will take 10 years for her money to double.

Step-by-step explanation:

The compound interest formula is given by:

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the number of years the money is invested or borrowed for.

In this exercise:

We want to find t for which the money doubles, that is, t when A = 2P.

Compounded monthly, an year has 12 months, so n = 12

Interest rate of 7%, so r = 0.07.

The following logarithm property is used:

[tex]\log{a^{t}} = t\log{a}[/tex]

So

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]2P = P(1 + \frac{0.07}{12})^{12t}[/tex]

[tex](1.0058)^{12t} = 2[/tex]

[tex]\log{(1.0058)^{12t}} = \log{2}[/tex]

[tex]12t\log{1.0058} = \log{2}[/tex]

[tex]t = \frac{\log{2}}{12\log{1.0058}}[/tex]

[tex]t = 10[/tex]

It will take 10 years for her money to double.

Lower Quartile: 2

Upper Quartile: 5.25

Median: 3

Final answer:

In the given data set 2, 2, 2, 4, 5, 6, the lower quartile is 2, the median is 3, and the upper quartile is 5.

Explanation:

To find the lower quartile, median, and upper quartile of the given data set 2, 2, 2, 4, 5, 6, we first need to organize it in ascending order, which is already done. Next, we compute the median, which is the middle value when the data set is listed in order. Since there are six numbers, the median will be the average of the third and fourth numbers, (2+4)/2, which is 3.

To find the first quartile (Q1) or lower quartile, we take the median of the lower half of the data set, not including the median. This would be the median of the first three numbers: 2, 2, and 2, which is simply 2. To find the third quartile (Q3) or upper quartile, we look at the upper half of the data set, again not including the median. The median of the last three numbers 4, 5, and 6 is 5.

Therefore, the lower quartile is 2, the median is 3, and the upper quartile is 5.
