Answer:

I believe it is C) decreasing when x > -1

Step-by-step explanation:

If you plot all 3 points on a graph, you will notice that the parabola is facing downwards. This means that on the left side of the vertex, it is increasing (the y-value increases). On the right side of the vertex, it decreases (y-value decreases). Note that "decreasing" refers to the y values.

So, since the vertex's x-value is -1 (we know this from the point (-1, 2)), any x-value greater than -1 will be to the right of the vertex. For example, 0, 1, 2, 3, etc. are all greater x-values than -1, so they are all to the right of -1. Since they are on the right, that means the corresponding-values will be decreasing.

Therefore, when x > -1, the parabola is decreasing.

What numbers are 1.4 units from −3.2 on a number line? pick one from both sets of answers
Fantom [35]

First, add 1.4 to the number given.

-3.2 + 1.4 = 1.4 - 3.2 = -2.2

a.-2.2 is one of your answer

Next, subtract 1.4 to the number given

-3.2 - 1.4 = -4.6

a.-4.6 is your next answer

a. -2.2, a. -4.6 are your two answers

hope this helps

Do consumers spend more on a trip to Store A or Store​ B? Suppose researchers interested in this question collected a systematic
FinnZ [79.3K]

Answer:

We can be 95% confident that consumers spend between $4.04 and $15.96 less at Store A than the consumers spend at Store B.

Step-by-step explanation:

Confidence Intervals give an estimate as range of values for a statistic concerned at a <em>confidence level</em>.

In this case the statistic is the mean difference between Store A and Store B purchase amounts and the confidence level is 95%.

Confidence Interval can be calculated using M±ME where

  • M is the sample mean difference between Store A and Store B purchase amounts
  • ME is the margin of error from the mean
