4. Both the Galapagos Islands and the island of Naura are on the Equator, but the Galapagos Islands are at 90.30◦W whereas the island of

Nauru is at 166.56◦E. How far is it from the Galapagos Islands to

Nauru traveling over the Pacific ocean along the Equator, correct to

the nearest km ?​

Answers

Answer:

Distance between Nauru and Galapagos islands = 11525 Km to the nearest Km

Step-by-step explanation:

The angle between the two Islands is given as X

X = (180 - 166.56) + (180 - 90.30)

X = 13.44° + 89.70°

X = 103.14

Distance between the islands = length of the arc with angle X subtended at the center of the earth of radius R.

Length of arc = (X/360) × 2πR

Where, R, radius of the earth = 6400 Km

Length of arc = (103.14/360) × 2π × 6400 Km

Length of arc = 11525.48 Km

Therefore, distance between Nauru and Galapagos islands = 11525 Km to the nearest Km

Answer:

The mode of the given data is 8.

Step-by-step explanation:

The complete question is: The number of credits being taken by a sample of 13​ full-time college students are listed below. Find the​ mean, median, and mode of the​ data, if possible. If any measure cannot be found or does not represent the center of the​ data, explain why.

9, 9, 12, 12, 9, 10, 8, 8, 8, 8, 8, 8, 11.

The​ mode(s) is/are nothing . ​(Type an integer or decimal rounded to one decimal place as needed. Use a comma to separate answers as​ needed.) B. The data set does not have a mode.

We are given the data for the number of credits being taken by a sample of 13​ full-time college students below;

Credits: 9, 9, 12, 12, 9, 10, 8, 8, 8, 8, 8, 8, 11.

Mode tells us that which value in our data set is appearing or occurring the maximum number of times.

As we can see in our data that the occurrence of the following credits are;

9 is occurring 3 times in our data.

12 is occurring 2 times in our data.

10 is occurring 1 time in our data.

8 is occurring 6 times in our data.

11 is occurring 1 time in our data.

Here, it is clear that the credit value of 8 is appearing the maximum number of times in our data set. So, the mode of the given data is 8.

given that (y+2) (y+3) and (2y^2+1) are consecutive terms of an arithmetic progression, find the possible value of y​

Answers

Answer:

-3/2 and 1

Step-by-step explanation:

Given the  arithmetic sequence  (y+2) (y+3) and (2y²+1), the common difference is gotten by taking the difference in their terms. For example if we have 3 terms T1, T2, T3... the common difference d = T2-T1 = T3-T2

From the  sequence given;

T1 = y+2, T2 = y+3 and T3 = 2y²+1

d = y+3-(y+2) = 2y²+1- (y+3)

open the parenthesis

y+3-y-2 = 2y²+1- y-3

1 = 2y²+1- y-3

1 = 2y²- y-2

2y²- y-2-1 = 0

2y²- y-3 =0

Factorize the resulting expression

2y²- y-3 =0

2y²- 2y+3y-3 =0

2y(y-1)+3(y-1) = 0

(2y+3)(y-1) = 0

2y+3 = 0 and y-1 = 0

2y = -3 and y =1

y = -3/2 and 1

Hence the possible values of y are -3/2 and 1

Step-by-step explanation:

First we need to find the area of the non shaded region within this shaded region. To find the area of this non shaded rectangle, use the formula base×height.

20×100=2000 ft².

Now we need to find the height and width of the shaded region which is,

25+25+20=70 Height

25+25+100=150 Width

mutiply these numbers 150×70=10500 ft²

Now we just need to subtract that inside area.

10500-2000=8500 ft²

C. There are two points where the whale touches the surface.

D. f is decreasing for the whale's entire path.

E. The point where the whale touches the surface is a maximum.

Answers

Answer:

Option (A) and (E)

Step-by-step explanation:

Characteristics of the quadratic function representing the path of a whale as it surfaces for air is,

y = -4x²

1). Since domain of the given function will be all real number x until ocean hits the shore on both the sides of the path.

2). Range of the function will be the value of y from the bottom of the ocean to the surface.

3). Whale will touch the surface of the ocean at one point only.

4). Function 'f' will increase initially upto the surface of the ocean and then it will decrease.

5). Point where the hale touches the surface will be maximum.

Therefore, Options (A) and (E) will be the correct options.

ΣY = 1055

ΣX² = 46023

ΣY²= 430407

ΣXY = 111448

n = 7

The correlation coefficient r =

r = 7(111448)-(523)(1055)/√7(46023)-(523)² × √7(430407)-(1055)²

r = 780136-551765/√322161-273529√3012849-1113025

r = 0.751

4. Test statistics

The p value is less than 0.05 so we reject null hypothesis. There is enough evidence to show a linear correlation between budgets and gross receipts.

Determine the sample size required to estimate the mean score on a standardized test within 4 points of the true mean with 98% confidence. Assume that s = 14 based on earlier studies.

Answers

Answer: 67

Step-by-step explanation:

Formula to calculate sample size: [tex]n=(\dfrac{z^*\times s}{E})^2[/tex] , where s = standard deviation on prior studies , z* = two tailed critical value for confidence level , E = margin of error

Given: E = 4 , s= 14 and confidence level = 98%

Z-value for  98% confidence = 2.326

Then, required sample size: [tex]n=(\dfrac{2.326\times 14}{4})^2=(8.141)^2=66.275881\approx67[/tex]

Hence, the required sample size = 67 .

Sample size required to estimate the mean score on a standardized test  is 67.

The confidence level (C) = 98% = 0.98

α = 1 - C = 0.02

α/2 = 0.02/2 = 0.01

The z score of α/2 is the same as the z score of 0.49 (0.50 - 0.01) which is equal to 2.33

Given that:

Standard deviation (σ) = 14, margin of error (E) = 4, n = sample size, hence:

[tex]E=z_\frac{\alpha}{2}*\frac{\sigma}{\sqrt{n} } \\\\4=2.33*\frac{14}{\sqrt{n} } \\\\\sqrt{n}=8.155\\\\n=67[/tex]

Hence the sample size required to estimate the mean score on a standardized test  is 67.
