<u>Answer:</u>

  • <u>The value of x is 19.</u>

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

<u>We know that both of these expressions are equal because of vertically opposite angles. Let's solve.</u>

  • => 7x - 8 = 6x + 11
  • => 7x - 6x = 19
  • => x = 19

<u>Hence, the value of x is 19.</u>

Hoped this helped.

Answer:

x= 19

Step-by-step explanation:

Recall the Vertical Angles Theorem which states that when two lines intersect, vertical angles are congruent. In this case, 7x-8 and 6x +11 are vertical angles, so they are congruent. We can conclude that an equation can be made to find the value of x where:

7x-8=6x+11

Solve out the equation to find the value of x.

7x-8+8=6x+11+8

7x=6x+19

7x-6x=6x+19-6x

x=19

Determine the level of measurement of the variable. an officer's rank in the military Group of answer choices
ElenaW [278]

Answer:

Ordinal

Step-by-step explanation:

Level of measurement used in statistics summarizes what statistical analysis that is possible. There exist three types of level of measurement. The nominal, ordinal and Interval/Ratio level of measurement. Here, our primary focus will be the Ordinal level of measurement.

Ordinal level of measurement indicates the position in a sequence. In the military sector, the officer's rank is said to be Ordinal. This implies that the ordinal level of measurement categorizes variables according to hierarchy or ranks with a meaningful order. Still, the intervals and differences between the variables may not be equal.

Value of t? 1.4t — 0.4 (t — 3.1) = 5.8
IceJOKER [234]

Hi!

<h3>Use the distribution property</h3>

1.4t — 0.4 * t - 0.4 * —3.1 = 5.8

1.4t — 0.4t - 1.24 = 5.8

<h3>Simplify</h3>

1t - 1.24 = 5.8

<h3>Add 1.24 to both sides</h3>

1t - 1.24 + 1.24 = 5.8 + 1.24

1t = 7.04

<u>t = 7.04</u>

<h2>The answer is t = 7.04</h2>

Hope this helps! :)

Alex Ar [27]

Answer:

Some answers to the reducing fraction sheet

Q14 = 4/5 because divide 12 and 15 by 3

Q15=can't be reduced because 11 is a prime number so it can't be divided by anything

Q17=can't be reduced because 17 is a prime number

Q18=can't be reduced because 13 is a prime number

Q19=38/9 because 114 and 27 would be divided by 3

Q20= -1/1 because you would divide both 14,529 by itself would equal to - 1/1

I can only help you with this sheet I can't help you with the other one hope this was helpful! :)

lisov135 [29]

Answer:

Reject Null Hypothesis given that  P-value < ∝

Step-by-step explanation:

Applying the Five ( 5 ) step model and assuming ∝ = 0.05

First step : determine the Null hypothesis

H0 : Age and support for Anti-smoking = independent

Second step : Determine the alternate hypothesis

Ha : Age and support for Anti-smoking ≠ independent

Thirdly : Identify significance level ( ∝ ) = 0.05

4th step : Calculate the Test statistic and P-value

Chi-squared test = 36.1429 using excel function

P-value =  1 - CHISQ.DIST(36.1429, 1, TRUE)  < 0.0001

finally : we can conclude that Age and support for Anti -smoking are not Independent hence we Reject The Null hypothesis. Given that

P-value < ∝
