Answer:(1) 33% (2) 27% (3) 33% (4) 48% (5) 33% (6) 35% (7) there is a difference because theoretical is statistics and logistics while experimental probability is randomized as and answer

Step-by-step explanation: you have three options of you two coins to land so if you were to divide that by 100 you would get .333333 so on and so forth and putting that to percent is 33% then on the experimental probabilities it was the number of times it landed divided by 100

How would you find the answer to -200 + 14?

Oliga [24]

Answer:

-186

Step-by-step explanation:

When you add a positive number to a negative, it gets bigger (In value) . For example:

-5 + 4 = -1

-10 + 12 = 2

So for this equation, -200 + 14, all you have to do is subtract 14 from 200, which will get you 186.

Since you removed the negative, add it back to get -186

The weekly amount of money spent on maintenance and repairs by a company was observed, over a long period of time, to be approxi

VikaD [51]

Answer:

$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Normally distributed with mean $480 and standard deviation $20.

This means that $\mu = 480, \sigma = 20$

How much should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05?

This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95, so X when Z = 1.645.

$Z = \frac{X - \mu}{\sigma}$

$1.645 = \frac{X - 480}{20}$

$X - 480 = 1.645*20$

$X = 512.9$

$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05
