The function f is such that f(x)=4x-1 find f^-1(x)
zvonat [6]
Let y=4x-1
The inverse is basically expressing x in terms of y.
y=4x-1  =>
y+1=4x
x=(y+1)/4
Since the inverse is still a function of x, we only have to interchange x and y
inverse of f(x) = f^-1(x) = (x+1)/4

If it takes 4 men 6hours to repair a road, how long will it take 7 men to do the job if they work at the same rate.
Crank
Tricky question. This isn't a ratio question even though it seems like one.

First divide 7 by 4.
7 \div 4 = 1.75

With more men, the hours taken to repair a road will be even shorter.

So next divide 6 by 1.75.
6 \div 1.75 = 3.43

Answer : It'll take 3.43 hours to do the job if they work at the same rate.

Hope this helps. - M

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

In the textile industry, a manufacturer is interested in the number of blemishes or flaws occurring in each 100 feet of material
klemol [59]

Answer:

The probability that can be applied to the given situation is Poisson distribution

Step-by-step explanation:

The probability that can be applied to the given situation is Poisson distribution because this distribution applied when the duration of occurrence of an event is known. In the given question laws have occurred every 100 feet therefore we have the number of events that have occurred. Moreover, Poisson distribution predicts the probability of events in fixed time interval
