Given: Isosceles TriangleDEF. The measure of vertex Angle D is four times the measure of each base angle E and F.

777dan777 [17]

Answer:

D = 120° , E = 30° , F = 30°

Step-by-step explanation:

Let D = 4x

Let E&F = x

4x + x + × = 180°[angles in triangle is 180°]

6x = 180°

x = 180/6

x = 30°

E = 30°

F =30°

D =4(30°)

=120°

A small company can produce up to 200 handmade sandals a month. The monthly cost, C, of producing x sandals is C(x) = 1000 + 5x.

wariber [46]

I will assume the more likely selection of $10 per sandal as opposed to $0.05 per sandal. So with the formulas c = 1000 + 5x r = 75x - 0.4x^2 Sandals Cost Revenue Profit or Loss 0 $1,000.00 $0.00 -$1,000.00 1 $1,005.00 $74.60 -$930.40 2 $1,010.00 $148.40 -$861.60 3 $1,015.00 $221.40 -$793.60 4 $1,020.00 $293.60 -$726.40 5 $1,025.00 $365.00 -$660.00 6 $1,030.00 $435.60 -$594.40 7 $1,035.00 $505.40 -$529.60 8 $1,040.00 $574.40 -$465.60 9 $1,045.00 $642.60 -$402.40 10 $1,050.00 $710.00 -$340.00 11 $1,055.00 $776.60 -$278.40 12 $1,060.00 $842.40 -$217.60 13 $1,065.00 $907.40 -$157.60 14 $1,070.00 $971.60 -$98.40 15 $1,075.00 $1,035.00 -$40.00 16 $1,080.00 $1,097.60 $17.60 17 $1,085.00 $1,159.40 $74.40 18 $1,090.00 $1,220.40 $130.40 19 $1,095.00 $1,280.60 $185.60 20 $1,100.00 $1,340.00 $240.00 As you can see 16 sandals and up is profitable. At what production levels will the company lose money? a. between 0 and 10 or between 150 and 190 pairs, inclusive 150 and 190 c. between 10 and 20 or between 50 and 100, inclusive If you add up the profit between 10 and 20 you will get $-484 so 50 and 100 b. between 0 and 15 or between 160 and 200 pairs, inclusive 160 and 200 d. between 15 and 35 or between 75 and 125, inclusive Neither 15 and 35 or 75 and 125 will lose money.

The Wall Street Journal Corporate Perceptions Study 2011 surveyed readers and asked how each rated the Quality of Management and

kykrilka [37]

Answer:

The calculated χ² = 17.0281 falls in the critical region χ² ≥ 9.49 so we reject the null hypothesis that the quality of management and the reputation of the company are independent and conclude quality of management and the reputation of the company are dependent

The p-value is 0 .001909. The result is significant at p < 0.05

Part b:

40 > 8.5

35> 7.5

25> 4

Step-by-step explanation:

1) Let the null and alternative hypothesis as

H0: the quality of management and the reputation of the company are independent

against the claim

Ha: the quality of management and the reputation of the company are dependent

2) The significance level alpha is set at 0.05

3) The test statistic under H0 is

χ²= ∑ (o - e)²/ e where O is the observed and e is the expected frequency

which has an approximate chi square distribution with ( 3-1) (3-1)= 4 d.f

4) Computations:

Under H0 ,

Observed Expected E χ²= ∑(O-e)²/e

40 35.00 0.71

25 24.50 0.01

5 10.50 2.88

35 40.00 0.62

35 28.0 1.75

10 12.00 0.33

25 25.00 0.00

10 17.50 3.21

15 7.50 7.50

∑ 17.0281

Column Totals 100 70 30 200 (Grand Total)

5) The critical region is χ² ≥ χ² (0.05)2 = 9.49

6) Conclusion:

The calculated χ² = 17.0281 falls in the critical region χ² ≥ 9.49 so we reject the null hypothesis that the quality of management and the reputation of the company are independent and conclude quality of management and the reputation of the company are dependent.

7) The p-value is 0 .001909. The result is significant at p < 0.05

The p- values tells that the variables are dependent.

Part b:

If we take the excellent row total = 70 and compare it with the excellent column total= 100

If we take the good row total = 70 and compare it with the good column total= 80

If we take the fair row total = 50 and compare it with the fair column total= 30

The two attributes are said to be associated if

Thus we see that ( where (A)(B) are row and columns totals and AB are the cell contents)

AB> (A)(B)/N

40 > 1700/200

40 > 8.5

35> 1500/200

35> 7.5

25> 800/200

25> 4

and so on.

Hence they are positively associated
