Answer:

Since angle d, a, and e are supplementary, d+a+e =180 degrees.

Given that line LK and BC are parallel

By the alternate interior angle theorem, e=c and d=b.

Substitute:

d+a+e=b+a+c=180

Since b+a+c is the sum of the angles of triangle ABC, the sum of the interior angle of triangle ABC (which could be any triangle of any size and shape) is 180 degrees.

(1 point) A cup of coffee at 100 degrees celsius is put into a 30 degree celsius room when t=0. The coffee's temperature, f(t),

Lapatulllka [165]

Answer:your question seems incomplete but if you looking to find the resulting equation to solve for temperature at a particular time you can use this 28t^2

Step-by-step explanation:

F'(t) = 7(0.8)t

Integrating the RHS

Temp= integral of f'(t)= 28t^2

Therefore, T(°c)= 28t^2

Solve each equation and match them with the correct solution. Column A 1. \large -3x=42 : \large -3x=42 2. \large \frac{x}{-6}=-

ella [17]

Answer:

The answer is below

Step-by-step explanation:

1) -3x = 42

Divide both sides by -3

-3x/ -3 = 42 / -3

x = -14

Answer: p.x=-14

$\frac{x}{-6}=-9\\ \\Multiply\ both\ sides\ by\ -6\\\\\frac{x}{-6}*-6=-9*-6\\\\x=54$

Answer: j. x=54

3) 5x = 105

Divide both sides by 5

5x/ 5 = 105 / 5

x = 21

Answer: n. x=-21

4) x+37=-25

add -37 to both sides

x+37 - 37 =-25 - 37

x = -62

Answer: d. x=-62

5) x-42=-15

add 42 to both sides

x-42 + 42 =-15 + 42

x = 27

Answer: k. x=27

6)x - (-12) = -4

x + 12 = -4

add -12 to both sides:

x + 12 - 12 = -4 - 12

x = -16

Answer: f. x = -16

7) x - (-6) = 5

x + 6 = 5

add -6 to both sides:

x + 6 - 6 = 5 - 6

x = -1

Answer: r. x = -1

8)8-x = -12

8 - x + x + 12 = -12 + x = 12

x = 8 + 12

x = 20

Answer: c) x = 20

9) -9 - x = -6

x = -9 + 6

x = -3

Answer: s. x =-3

10) -6 + x = 17

x = 17 + 6

x = 23

Answer: a. x =23

11)

$\frac{x}{9} =-42\\multiply\ by \ 9\\\\x = 9*-42=-378$

Answer: b. x = -378

12) -16 = x - 8

x = -16 + 8

x = -8

Answer: q. x = -8

13) -25 = x + 17

x = -25 - 17

x = -42

Answer: h. x = -42

14) 36 = 8 - x

x = 8 - 36

x = -28

Answer: g. x = -28

15) -x + 6 = 11

x = 6 - 11

x = -5

Answer: m. x = -5

16) -x + 8 = 4

x= 8 - 4

x = 4

Answer: e. x =4

17) 16 = 4 -x

x = 4 - 16

x = -12

Answer: o: x = -12

18) 85 = -5x

x = 85/ -5

x = -17

Answer: l. x= -17

19) 21 = -x/7

x = 21 * -7

x = -147

Answer: i. x = -147

Why does the margin of error increase as the level of confidence increases? Choose the correct answer below. A. The margin of e

Debora [2.8K]

Answer:

The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin error.

Step-by-step explanation:

Margin of Error is a statistical measure of random sampling error insurvey results.

Level of confidence reflects percentage range around sample mean, that can be expected to contain population actual parameter.

High level of confidence means larger range band of confidence interval, supposed to contain the population parameter. This further implies high expected variation between sample statistic & actual parameter i.e Margin Error increases.
