Answer:

radius of a ^{112}Cd_{12} nucleus is 5.784×10^{-15} meters

Step-by-step explanation:

Since radius of a nucleus is measured by the formula

R = R_{0}(A)^{\frac{1}{3} }

Where R_{0} is the average radius of a nucleus. This radius varies with the size of nucleons.

In this formula A = number of nucleons = (Number of protons + neutrons)

For element Cd number of nucleons = 112

and R_{0} = 1.2×10^{-15}

Now we put these values in the given formula

R = 1.2\times 10^{-15}\times(112)^{\frac{1}{3}}

  =1.2\times 10^{-15}\times4.82

  = 5.784×10^{-15} meters

Therefore, radius of a ^{112}Cd_{12} nucleus is 5.784×10^{-15} meters

Answer:

Area= 50√3 units^2

Step-by-step explanation:

Given:

In given triangle, there are two sides with length 10√3 and 20 along with angle of 30° between them.

As the given triangle is SAS triangle, we'll use the following formula to calculate its area:

A=1/2absinC

where a= 20

b= 10√3

and c=30°

Now putting values we get:

A=(1/2)(20)(10√3) sin(30)

  =100√3(1/2)

   =50√3

so the area is 50√3 units^2 !

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
