Answer:

Option 3, p(0) = -10

Option 4, p(10) = 0

Step-by-step explanation:

<u>Step 1:  Check</u>

x - 10 + 10 = 0 + 10

<em>x = 10</em>

f(0) = 0 - 10 = -10

x = -10

<em>p(10) = 0</em>

Answer:  Option 3, p(0) = -10, Option 4, p(10) = 0

a wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points
Alla [95]

Answer:

Total number of edges for resulting solid = 12

Step-by-step explanation:

A wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points that are 1 inch from each corner.

We have to find the number of edges in the resulting solid after we cut the edges as told above.

There are two faces along the height which will become sharpened after we take out the cuts.

So the resulting shape would be like that of a cylinder with its both ends pointed.

So total number of edges = 4 + 4 + 4 = 12

Answer:

y = 20/3 * x + 125/3

Question 4 : 3 hours study for score 55 (?)

Step-by-step explanation:

2 points (2, 55) (5,75) were chosen to plot the line of best fit, cuz 5 on the above and 5 below it.

y = mx + b

m = (75 - 55) / (5 - 2) = 20/3

b = y - mx = 55 - (20/3) * 2 = 125/3

Equation: y = 20/3 x + 125/3

Suppose you are conducting a survey about the amount grocery store baggers are tipped for helping customers to their cars .for a
ELEN [110]

Using the Empirical Rule and the Central Limit Theorem, we have that:

  • About 68% of the sample mean fall with in the intervals $1.64 and $1.82.
  • About 99.7% of the sample mean fall with in the intervals $1.46 and $2.

<h3>What does the Empirical Rule state?</h3>

It states that, for a normally distributed random variable:

  • Approximately 68% of the measures are within 1 standard deviation of the mean.
  • Approximately 95% of the measures are within 2 standard deviations of  the mean.
  • Approximately 99.7% of the measures are within 3 standard deviations of the mean.

<h3>What does the Central Limit Theorem state?</h3>

By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation s = \frac{\sigma}{\sqrt{n}}.

In this problem, the standard deviation of the distribution of sample means is:

s = \frac{0.657}{\sqrt{50}} = 0.09

68% of the means are within 1 standard deviation of the mean, hence the bounds are:

  • 1.73 - 0.09 = $1.64.
  • 1.73 + 0.09 = $1.82.

99.7% of the means are within 3 standard deviations of the mean, hence the bounds are:

  • 1.73 - 3 x 0.09 = $1.46.
  • 1.73 + 3 x 0.09 = $2.
