If m > n, which inequalities must be true? Check all that apply.

ololo11 [35]

Step-by-step explanation:

m > n add 2.1 to both sides

m + 2.1 > n + 2.1 TRUE

m > n subtract (-4) from both sides

m - (-4) > n - (-4) TRUE

m > n add 16.5 to both sides

16.5 + m > 16.5 + n TRUE

m > n → 3 + m > n logic

3 + m > n add 6 to both sides

9 + m > 6 + n TRUE

Solve the equation below. SHOW UR WORK 10x − 6 = 24

Lina20 [59]

Answer:

Step-by-step explanation:

10x-6=24

10x = 24+6 (You switch sides because you can add 24 and 6. You cannot add 10x to 24 or 6)

10x= 30

x= 30/10

x= 3

The answer is 3.

A consumer group selected 100 different airplanes at random from each of two large airlines. The mean seat width for the 100 air

Novay_Z [31]

Answer:

Decreasing the sample size decreases the width of the confidence interval.

Step-by-step explanation:

-Let s be the sample standard deviation and $\bar X$ be the sample mean.

#We calculate the 95% confidence interval for the sample size 100 as below:

$\bar X\pm z_{0.05/2}\frac{s}{\sqrt{n}}\\\\\\=\bar X\pm 1.960\times\frac{s}{\sqrt{50}}\\\\\\=\bar X\pm 0.1960s$

#we then calculate the confidence interval of sample size =50 and of similar mean and standard deviation:

$\bar X\pm z\frac{s}{\sqrt{n}}\\\\\\=\bar X\pm z_{0.05/2}\times\frac{s}{\sqrt{n}}\\\\\\=\bar X\pm1.960\times \frac{s}{\sqrt{50}}\\\\\\\\=\bar X\pm0.2772s$

#Notice that the smaller sample(n=50) has a narrower confidence interval.

Hence, decreasing the sample size decreases the width of the confidence interval.
