9. Which expression is equivalent to -28x2 + 35x?

Answer:

Based on the findings, we infer that the average cost of a wedding is lower than the $30,000 that was initially suggested.

Step-by-step explanation:

The following data set is provided: (in thousands)

29100, 28500, 28800, 29400, 29800, 29800, 30100, 30600

Formula:

where denotes data points, represents the mean, and n indicates the number of samples.

The sum of squares of the differences equals 3408750

The population mean, μ = $30,000

The sample mean, = $29512.5

Sample size, n = 8

Alpha, α = 0.05

Sample standard deviation, s = $697.82

Initially, we formulate the null hypothesis and the alternative hypothesis.

A one-tailed t-test will be conducted for this analysis.

Formula:

<pinserting the="" values="" we="" derive="">

<pnow>

<pgiven the="" situation="">

<pwe do="" not="" accept="" the="" null="" hypothesis="" and="" reject="" it.="">

Thus, we conclude that the average wedding cost is indeed less than the advertised $30,000.

8.25 inches after multiplying the 3/4 by 2, and adding that to the previous 3/4, gives you the final height of the plant.

To illustrate 1 hundredth (or 1%) on a grid consisting of 100 units, shade only 1 unit. In contrast, to illustrate 1 tenth (or 10%), you would shade 10 units. A visual representation of the grid would be helpful for further explanation.

The same device is used to measure safetrack in the same manner.
