The sum of two consecutive integers is 26. What are the integers? Question does not specify even or odd consecutive integers. Please HELP!

Answers

X is some integer


X+1 is the consecutive integer
Consecutive interferes are numbers like { 5,6,7 } or { 11,12,13 }. They are numbers that follow after one another

We sum x and x+1 getting 26 which means
x+(x+1)=26

2x+1=26

2x=26-1

2x=25

x=25/2

x=12.5

We made x an internet but 12.5 isn’t a integer so there are no solutions to the first integer equation.
So there are no consecutive integers that add up to 26.

If your teacher said consecutive even integers then your equation would be

x+(x+2)=26

2x+2=26

2x=24

x=24/2

x=12

And we can see that x=12 and x+2=12+2=14 add 12+14=26

Thar only applies if your teacher wrote consecutive even integers. With that even left out there are no solutions

An article presents a study of the effect of the subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway. In six applications of a 160 kN load on a runway with a subbase thickness of 864 mm, the average surface deflection was 2.34 mm with a standard deviation of 0.090 mm. Find a 90% confidence interval for the mean deflection caused by a 160 kN load. Round the answers to three decimal places. The 90% confidence interval is ( , ).

Answers

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean.

Given that: sample size (n) = 6, standard deviation (σ) = 0.09 mm, mean (μ) = 2.34 mm

The confidence interval = 90% = 0.9

α = 1 - 0.9 = 0.1

α / 2 = 0.05

The z score of 0.05 is the same as the z score of 0.45 (0.5 - 0.05) which is 1.645.

The margin of error is given as:

[tex]E=Z_{\frac{\alpha}{s} }*\frac{\sigma}{\sqrt{n} }[/tex]

[tex]E=1.645*\frac{0.09}{\sqrt{6} }=0.06\ mm[/tex]

The confidence interval = μ ± E = 2.34 ± 0.06 = (2.28, 2.40)

The confidence interval is between 2.28 mm and 2.4 mm
