Answer:

the answer to this sequence is that: u count the difference between 19 and 11 , which is 8.

again try to see if the difference is same between 11 and 3, which is again 8.

so the commin difference in this sequence is = 8

3. Given ABCD ≅ FGHJ and mC = 9x - 7, mH = 5x + 13, find the value of x and the measures of angle C and angle H. Show all work

Bas_tet [7]

Since congruence and similarity for polygons is posted in a specific order, we know that angle A=angle F, side A=side F, die B=side G, and so on. Therefore, we have that angle C=angle H = 9x-7=5x+13. Subtracting 5x from both sides to separate the x using the subtraction property of equality, we get 4x-7=13. Next, we can add 7 to both sides to get 4x=20, and divide both sides by 4 to isolate the x and get x=5. Plugging that into angle C or angle H, we get that 9x-7=9*5-7=45-7=38=5*5+13.

4. A statistician working for the National Basketball Association supplies the television announcers with interesting statistics

Sonbull [250]

Answer: 0.038

Step-by-step explanation:

Given: Total games : n= 375

Number of games won by the team that was winning the game at the end of the third quarter. = 300

The proportion (p) of the team that was winning the game at the end of the third quarter: $p=\dfrac{300}{375}=0.8$

Critical z-value for 90% confidence: z* = 1.645

Margin of error = $z^*\sqrt{\dfrac{(1-p)p}{n}}$

The margin of error in a 90% confidence interval estimate of p $=1.645\sqrt{\dfrac{0.2\times0.8}{300}}\\= 1.645\times\sqrt{0.00053333}\\\\=1.645\times0.0231\\\\=0.0379995\approx$$0.038$

Hence, the required margin of error = 0.038

Help out?? Mathematics image.

Answer: (12) ∠1 = 20° (13) ∠2 = 50° (14) ∠3 = 15° (15) UV = 80° (16) AB = 40° (17) ABC <em>or</em> 180° - CD (18) BC - 140° (19) ABC = 150°

<u>Step-by-step explanation:</u>

12) $\frac{1}{2}$ (UV - ST) = ∠1

$\frac{1}{2}$ (80 - 40) = ∠1

$\frac{1}{2}$ (40) = ∠1

20 = ∠1

13) $\frac{1}{2}$ (UV + ST) = ∠2

$\frac{1}{2}$ (70 + 30) = ∠2

$\frac{1}{2}$ (100) = ∠2

50 = ∠2

14) $\frac{1}{2}$ (VB - BS) = ∠3

$\frac{1}{2}$ (60 - 30) = ∠3

$\frac{1}{2}$ (30) = ∠3

15 = ∠3

15) $\frac{1}{2}$ (UV - ST) = ∠1

$\frac{1}{2}$ (UV - 20) = 30

UV - 20 = 60

UV = 80

16) ∠1 = arc AB

∠1 = 40

arc AB = 40

17) arc AB + arc BC = arc AC

= 180 = arc CD

18) ∠1 + ∠2 + ∠3 = 180

20 + ∠2 + 20 = 180

∠2 + 40 = 180

∠2 = 140

19) ∠1 + ∠ 2 = arc ABC

∠1 + ∠2 + ∠3 = 180

arc ABC + 30 = 180

arc ABC = 150
