What is the linear inequality of y>-2

Your question is a bit ambiguous. Are you supposed to describe the inequality in words? or to graph it? Please share the instructions and don't use "What is ... "

<span>y>-2 can be graphed easily. Think: the x-axis is the line y=0. The line y= -2 is also a horiz. line, but it passes thru (0, -2) instead of thru the origin (0,0).

Because of the inequality symbol, you must draw y = -3 as a dashed (not solid) line.

Last, you'd need to shade the entire area above the dashed line y = -3. The shaded area is the "solution" of </span><span>y>-2.</span>

The first picture about the rational numbers I am not sure the answer.

In the second picture the set that are all equivalent to the fraction is the second set.

In the third picture

the equivalent expression is the first one.

In the fourth picture the correct situation is the first one about buying popcorn.

Hope this helps a little, sorry I could not help more.

a) Suppose that a random sample of size 80 has a sample mean of 1.69 ppb and a sample standard deviation of 0.25 ppb. Find a 95%

lys-0071 [83]

Answer: The confidence interval is 1.69ppb±0.055

Step-by-step explanation:

To find the confidence interval, first find the z* which is the appropriate z*-value related to the confidence interval of preference. As in this is 95%, z*-value = 1.96 (Note: The value is from the standard normal Z distribution).

With the z*-value, multiply by the division of the standard deviation and the square root of the sample size:

z*-value . σ/√n = 1.96 · $\frac{0.25}{\sqrt{80} }$ = 0.055

The 95% confidence interval of the sample mean of 1.69 ppb is 1.69ppb±0.055ppb
