At Food Lion, an 8-ounce container of Daisy sour cream is $1.52. Kraft sour cream sells for $2.92 for 12 ounces. Which is the better buy and by how much?

Answers

Answer 1

Answer:

Answer:

The 8-ounce container of daisy sour cream

Step-by-step explanation:

It's the 8-ounce container of Daisy sour cream because if you buy two of those, it would cost $3.04 for 16 ounces. If you bought one Kraft sour cream for 12 ounces, it would be $2.92. So you can get two 8-ounce containers of Daisy sour cream near the price of the price for the Kraft sour cream for $2.92. You would have to pay an extra 12 cents if you want 16 ounces of sour cream.

A quality control chart is used to monitor the customer wait time at a local call center. Sample means of five times are averaged and plotted over time. The last 50 sample means are randomly distributed between the upper and lower control limits. The process is _______.

Answers

Answer:

in-control

Step-by-step explanation:

basically, their are 2 types of control charts delineated:

1) uni-variate control chart : shows one quality characteristic

2)multivariate control chart : shows 2 or more than two quality characteristics

in statistics, we have "upper control limit" and "lower control limit".

if the system/variables are within these limits it is 'in-control' other wise 'out of control'

in-controlsays that all dots are within control limit and they have random pattern.

A study conducted at a certain college shows that 54% of the school's graduates move to a different state after graduating. Find the probability that among 7 randomly selected graduates, at least one moves to a different state after graduating.

Answers

Answer:

99.56% probability that among 7 randomly selected graduates, at least one moves to a different state after graduating.

Step-by-step explanation:

For each graduate, there are only two possible outcomes. Either they move to a different state, or they do not. The probability of a graduate moving to a different state is independent of other graduates. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_(n,x).p^(x).(1-p)^(n-x)$

In which $C_(n,x)$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_(n,x) = (n!)/(x!(n-x)!)$

And p is the probability of X happening.

54% of the school's graduates move to a different state after graduating.

This means that $p = 0.54$

7 randomly selected graduates

This means that $n = 7$

Find the probability that among 7 randomly selected graduates, at least one moves to a different state after graduating.

Either none moves, or at least one does. The sum of the probabilities of these events is 1. So

$P(X = 0) + P(X \geq 1) = 1$

We want $P(X \geq 1)$ . Then

$P(X \geq 1) = 1 - P(X = 0)$

In which

$P(X = x) = C_(n,x).p^(x).(1-p)^(n-x)$

$P(X = 0) = C_(7,0).(0.54)^(0).(0.46)^(7) = 0.0044$

$P(X \geq 1) = 1 - P(X = 0) = 1 - 0.0044 = 0.9956$

99.56% probability that among 7 randomly selected graduates, at least one moves to a different state after graduating.

If $75 is invested at an interest rate of 8% per year and is compounded monthly, how much money is in the account in 15 years?

Answers

The amount of money is $248.02.

Principal amount = P=75

Interest rate = r = 8% = 0.08

Number of years = t = 15

Number of times compounded in a year = n = 12

A = Amount after t years.

After 15 years there will be:

$A=P\left(1+(r)/(n)\right)^(nt)\nA=75\left(1+(0.08)/(12)\right)^(\left(12\cdot15\right))\nA=248.019110806\nA \approx 248.02$

Answer:

$248.03

Step-by-step explanation:

The formula you use for this is as follows:

$A(t)=P(1+(r)/(n))^(nt)$

where A(t) is the amount after the compounding is done, P is the initial amount invested, r is the interest rate in decimal form, n is the number of times the compounding is done per year, and t is the time in years. Using that information and filling in our equation gives us this:

$A(t)=75(1+(.08)/(12))^((12)(15))$

which simplifies down to

$A(t)=75(1+.0066667)^(180)$

which simplifies further to

$A(t)=75(3.307118585)$

which multiplies to $248.0338938. Round to the nearest cent to get your answer.
