Answer:

8500 ft²

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

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

Answer:

Net Cash-flow = Cash Inflows - Cash Outflows

The net amount of cash that a company has is the difference between the cash coming in(revenue) and the cash going out (expenses).

Spreadsheet 1

= Cash Inflows - Cashflows

= 2,350 - 2,335

= $15

Spreadsheet 2

= Cash Inflows - Cashflows

= 2,270 - 2,260

= $10

Spreadsheet 3

= Cash Inflows - Cashflows

= 2,380 - 2,380

= $0

Spreadsheet 4

= Cash Inflows - Cashflows

=  2,150 - 2,055

= $95

Spreadsheet 4 has the greatest net cash flow at $95.

Answer:The answer is A

Answer:

1st evening = 7 + 20 = 27 calls

2nd evening = 3 (20 ) = 60 call

3rd evening = 20 calls

Step-by-step explanation:

total calls for the last three evenings = 107 phone calls

2nd evening = 3x as many calls as the 3rd evening

1st evening = 7 more calls than the 3rd evening.

find:

how many calls did she receive each evening?

let T (total) = 107

let x = 3rd evening.

let 2nd = 3x

let 1st = (7 + x)

T = 1st + 2nd + 3rd

107 = (7 + x) + 3x + x

107 - 7 = 5x

100 = 5x

x = 100 / 5

x = 20

therefore,

1st evening = 7 + 20 = 27 calls

2nd evening = 3 (20 ) = 60 call

3rd evening = 20 calls

Answer:

1st  = 27 calls

2nd  = 60 call

3rd = 20 calls

Step-by-step explanation:

total calls = 107 phone calls

2nd  = 3x

1st = 7 + 3x

T (total) = 107

T = 1st + 2nd + 3rd

107 = (7 + x) + 3x + x

107 - 7 = 5x

100 = 5x

x = 100 / 5

x = 20

so,

1st = 7 + 20 = 27 calls

2nd  = 3 (20 ) = 60 call

3rd  = 20 calls

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.

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.

Find the mode. Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice. A. 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.

Step-by-step explanation:

Number of team = 13

Let us consider a graph with 13 vertices, each edge represents a match of two teams.

Total number of edges = 13(13-1)/2 =78 edge

Given conditions:

Each component plays 7 match with 7 other teams.

Total edges in the case = 7(6)/2 =21

Therefore edges in the graph are not equal to edges in the condition.

Therefore impossible to implement

Answer:

16 and 25

Step-by-step explanation:

Given that the square root of n = 4.2, let's find an expression for this, then find the possible value of n.

Thus:

[tex] \sqrt{n} = 4.2 [/tex]

Solve for n. Square both sides.

[tex] (\sqrt{n})^2 = (4.2)^2 [/tex]

[tex] n = 17.64 [/tex]

Therefore, if the sqrae root of n was approximately equal to 4.2, then we can conclude that n is between 16 and 25.

3. ΣX = 523,

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

= 228371/220.53*1378.34

= 228371/303965.32

r = 0.751

4. Test statistics

t = r√n-2/√1-r²

= 0.751√5/√0.5640

= 1.679/0.660

= 2.543

5. P value

Degrees of freedom n-2 = 5

T dist(2.543,5,2)

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.

Answer:

0.065354330709 inch

Step-by-step explanation:

1 millimeter is equal to 0.03937007874 inches, so 1.66 mm is 0.065354330709 inches.

This comes from the definition 1 inch = 2.54 cm

so 1 inch = 25.4 mm. Divide by 25.4 and get:

0.03937007874 inch = 1 mm

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: 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.
