Answer:

1. 2x+2-(2x-14)=5x+2

0x+16=5x+2

16=5x+2

14=5x

14/5=x or 2.8=x

2. 2x+10-(-2x+7)=-7x+14

4x+3=-7x+14

11x+3=14

11x=11

x=1

1) x=2.8

2) x=1

Step-By-Step:

Q1) <em>2x + 2 - (2x - 14) = 5x + 2 </em>

<em>Simply</em><em> </em><em>the</em><em> </em><em>expression</em><em> </em>

<em>2x</em><em>+</em><em>2-2x</em><em>+</em><em>14</em><em>=</em><em>5x</em><em>+</em><em>2</em>

<em>collect</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em>

<em>(</em><em>2x-2x</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>+</em><em>14</em><em>)</em><em> </em><em>=</em><em> </em><em>5x</em><em>+</em><em>2</em>

<em>simplify</em>

<em>16= 5x+2</em>

<em>swap</em><em> </em><em>sides</em><em> </em>

<em>5x</em><em>+</em><em>2</em><em>=</em><em>16</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em>-2</em><em> </em><em> </em><em> </em><em>-2</em>

<em>5x</em><em>=</em><em>16-2</em>

<em>5x</em><em>=</em><em>14</em><em> </em>

<em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>on</em><em> </em><em>its</em><em> </em><em>own</em><em> </em><em>we</em><em> </em><em>divide</em><em> </em><em>each</em><em> </em><em>side</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>so</em>

<em>5x</em><em>=</em><em>14</em>

<em>÷</em><em>5</em><em> </em><em> </em><em>÷</em><em>5</em>

<u><em>x</em><em>=</em><em> </em><em>2</em><em>.</em><em>8</em></u><em> </em>

Q2) <em>2x + 10 - (-2x + 7) = -7x + 14 </em>

<em>Simply</em><em> </em><em>the</em><em> </em><em>expression</em><em> </em>

<em>2x</em><em>+</em><em>10</em><em>+</em><em>2x-7</em><em>=</em><em> </em><em>-7</em><em>+</em><em>14</em>

<em>collect</em><em> </em><em>like</em><em> </em><em>terms</em>

<em>(2x+</em><em>2x</em><em>)</em><em>+</em><em>(</em><em>10-7</em><em>)</em><em>=</em><em> </em><em>-7</em><em>+</em><em>14</em>

<em>simplify</em><em> </em>

<em>4x</em><em>+</em><em>3</em><em>=</em><em>7</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em>-3</em><em> </em><em>-3</em>

<em>4x</em><em>+</em><em>3-3</em><em>=</em><em>7-3</em>

<em>simplify</em><em> </em>

<em>4x</em><em>=</em><em>7-3</em>

<em>4x</em><em>=</em><em>4</em><em> </em>

<em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>on</em><em> </em><em>its</em><em> </em><em>own</em><em> </em><em>divide</em><em> </em><em>each</em><em> </em><em>side</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>so</em><em>.</em><em>.</em><em>.</em>

<em>4x</em><em>=</em><em>4</em>

<em> </em><em>÷</em><em>4</em><em> </em><em>÷</em><em>4</em>

<em>x</em><em>=</em><em>1</em>

vova2212 [387]

Answer: See explanation

Step-by-step explanation:

1. Use the five steps of hypothesis testing.

Step 1: The aim of the research is to conduct the five steps of hypothesis testing.

Step 2:

Null hypothesis: H0 u= 4

Population mean: H1 u = 4

Alternate hypothesis: u ≠ 4

Population mean: u ≠ 4

Step 3 and step 4 are attached.

Step 5: Based on the calculation, the calculated value of t is less than the t critical value, therefore, the null hypothesis will be failed to be rejected.

2. Sketch the distributions involved

This has been attached.

3. Explain the logic of what you did to a person who is familiar with hypothesis testing, but knows nothing about t tests of any kind.

The distribution is "t".

The means is tested by using T-test.

Chi-square is used to test the single variance.

Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, .... PLEASE HELP ASAP
sesenic [268]

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = \frac{135}{45}=3

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

a_n=a(r)^{n-1}

a_n=45(3)^{n-1}

Recursive formula of this sequence will be,

a_n=3(a_{n-1}), a_1=45

Therefore, Option (B) will be the answer.

anygoal [31]
Since we are already given with the formula to solve for the coordinates of point L, all we have to do is to perform the necessary operation in the item. The formula for the coordinates of the midpoint is,                    M = ((5 + 1) / 2 , (3 - 7) / 2)performing the operation,                   M = (3, -2)Thus, the coordinates of point L are (3,-2).
