If six pencils cost $24, how much does 1 pencil cost?

6p = 24

divide both sides by 6 to get p alone:
6p/6 = 24/6

simplify:
p = 4.

So p = 4 is our answer, and in this case, one pencil would equal $4.

In an examination of purchasing patterns of shoppers, a sample of 16 shoppers revealed that they spent, on average, $54 per hour

Lesechka [4]

Answer:

$54-1.64\frac{21}{\sqrt{16}}=45.39$

$54 +1.64\frac{21}{\sqrt{16}}=62.61$

So on this case the 90% confidence interval would be given by (45.39;62.61)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

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".

$\bar X=54$ represent the sample mean

$\mu$ population mean (variable of interest)

$\sigma=21$ represent the sample standard deviation

n=16 represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

Since the Confidence is 0.90 or 90%, the value of $\alpha=1-0.9=0.1$ and $\alpha/2 =0.05$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.05,0,1)".And we see that $z_{\alpha/2}=1.64$

Now we have everything in order to replace into formula (1):

$54-1.64\frac{21}{\sqrt{16}}=45.39$

$54 +1.64\frac{21}{\sqrt{16}}=62.61$

So on this case the 90% confidence interval would be given by (45.39;62.61)

What is 2 1/2 /1/3 ?

DanielleElmas [232]

Answer:

15/2

Step-by-step explanation:

My interpretation of your math expression is "2 1/2 divided by 1/3."

I prefer to write this as:

5 1

----- ÷ -----

2 3

which is equivalent to:

5 3

----- * ----- = 15/2

2 1

Find MQ in parallelogram LMNQ .

Liula [17]

Answer:

MQ = 16.4

By the Parallelogram Diagonals Theorem , MP = PQ

So MQ = 2 · MP

Step-by-step explanation:

Parallelogram Diagonals Theorem

The diagonals of a parallelogram bisect each other, i.e. they divide each other into two equal parts.

P is the point of intersection of the diagonals.

Therefore, MP = PQ and LP = PN

If MP = 8.2, then PQ = 8.2

⇒ MQ = 8.2 + 8.2 = 16.4

Tript Corporation has a process costing system and uses the weighted-average method. The company had 3,000 units in work in proc

ycow [4]

Answer:

11,000 units were started into production which were 100 % complete for materials and 89.1 % complete for Conversion Costs.

Step-by-step explanation:

With the help of Equivalent Units of Production we find out how many units were started.

11,000 units were started into production.

Tript Corporation

Physical Units % of Completion Equivalent Units

w.r.t Conversion Costs Mat Conversion C

Units Started 11,000 89.1% 11,000 9,800

Beginning WIP 3000 60% 3000 1800

Total units accounted For 14,000 11600

We compare the Equivalent units and then find the required balance amounts

Physical Units % of Completion Equivalent Units

w.r.t Conversion Costs Mat Conversion C

Units Completed 10,000 100 10,000 10,000

WIP Ending 4000 40% 4000 1600

Total units accounted For 14,000 11,600
