Answer:

53

To find:

x

Step-by-step explanation:

0.3x+5.14=2.1x – 4.4

0.3x-2.1x=-4.4-5.14

-1.8x=-9.54

x=-9.54/-1.8

To remove the decimal point, multiply with 100 on both numerator and denominator as their are two digits after the decimal point

x=-9.54 × 100/-1.8 × 100

therefore you will get,

x=-954/-180

cut the negative sign from both numerator and denominator

x=954/180

x=53

hope it helps you!!

Albert Abbasi, VP of Operations at Ingleside International Bank, is evaluating the service level provided to walk-in customers.
In-s [12.5K]

Answer:

The probability that Albert's sample of 64 will have a mean between 13.5 and 16.5 minutes is 0.9973.

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Let X the random variable that represent interest on this case, and for this case we know the distribution for X is given by:

X \sim N(\mu=15,\sigma=4)  

And let \bar X represent the sample mean, the distribution for the sample mean is given by:

\bar X \sim N(\mu,\frac{\sigma}{\sqrt{n}})

On this case  \bar X \sim N(15,\frac{4}{\sqrt{64}})

Solution to the problem

We are interested on this probability

P(13.5  

If we apply the Z score formula to our probability we got this:

P(13.5

=P(\frac{13.5-15}{\frac{4}{\sqrt{64}}}

And we can find this probability on this way:

P(-3

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-3

The probability that Albert's sample of 64 will have a mean between 13.5 and 16.5 minutes is 0.9973.

A set of positive integers {1, 2 , 3 , 4, 5 , 6 , 7 , 8 , 9} is used to form a pack of nine cards. each card displays one positi
ivanzaharov [21]
If the largest integer drawn among the four cards is 5, then that means that 3 of the cards drawn are from the set {1, 2, 3, 4}. The number of ways of selecting 3 cards from 4 cards is given by:

^4C_3=4

If the largest integer drawn among the four cards is 6, then that means that 3 of the cards drawn are from the set {1, 2, 3, 4, 5}. The number of ways of selecting 3 cards from 5 cards is given by:

^5C_3=10

If the largest integer drawn among the four cards is 7, then that means that 3 of the cards drawn are from the set {1, 2, 3, 4, 5, 6}. The number of ways of selecting 3 cards from 6 cards is given by:

^6C_3=20

Therefore, <span>the number of selections grace could make if the largest integer drawn among the four cards is either a 5, a 6 or a 7 is given by 4 + 10 + 20 = 34 selections.</span>
