Solve for x. -1+14x 12+17
tino4ka555 [31]

Answer:

x=9

Step-by-step explanation:

These two angles are equal since they are alternate exterior angles

-1 +14x = 12x+17

Subtract 12x from each side

-1 +14x-12x = 12x-12x+17

-1+2x= 17

Add 1  to each side

-1+1+2x = 17+1

2x = 18

2x/2 = 18/2

x =9

Please answer quickly thanks
Anastaziya [24]
8/3 = 2 2/3 and -11/3 = -3 2/3
so the middle line is 0 and each big line is 1.
Put the first dot on 2 2/3 or right before the 3rd big line.
Put the second dot on -3 2/3 or the line right after the 4th big line going back from 0

The mean exam score for the first group of twenty examinees applying for a security job is 35.3 with a standard deviation of 3.6
babymother [125]

The scores of two groups can be compared using coefficient of variation;

Coefficient of variation (C.V.) = (Standard Deviation/ Mean) × 100%;

For Data set 1;

Standard deviation = 3.6

Mean = 35.3

C.V. = (3.6/35.3) × 100%;

       = 10.19%

For Data set 2;

Standard deviation = 0.5

Mean = 34.1

C.V. = (0.5/34.1) × 100%;

       = 1.46%

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times
mafiozo [28]
  • Answer:

<em>a = 30°</em>

<em>b = 70°</em>

<em>c = 80°</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em />

<em>a ; b ; c = angles</em>

<em>a + b + c = 180°</em>

<em>b + c = 5a</em>

<em><u>replace (b + c)</u></em>

<em>a + (b + c) = 180</em>

<em>a + 5a = 180</em>

<em>6a = 180</em>

<em>a = 30°</em>

<em />

<em>b + c = 180 - a</em>

<em>b + c = 150</em>

<em>c = b + 10</em>

<em><u>replace c</u></em>

<em>b + (b + 10) = 150</em>

<em>2b = 150 - 10</em>

<em>2b = 140</em>

<em>b = 70°</em>

<em>c = b + 10</em>

<em>c = 80°</em>

<em>Good luck !</em>
