If 5 oranges cost $2 you can divide 2 by 5 to get the cost of each individual orange and then you must multiply that by 24 to get the total cost.

So if 5 oranges cost 2 dollars, then 10 cost 4, 15 cost 6, 20 cost 8,
and 25 cost 10. We need 24, so now we need to find out the cost for 24 oranges.
Looking at how much they go up by, we can see that each time it goes up by about 0.5
So your final answer would be: 2 dozen oranges cost $9.50

A market researcher for a provider of music player accessories wants to know the proportion of customers who own cars to assess

Luba_88 [7]

Answer:

Step-by-step explanation:

Hello!

To evaluate the market for a new car charger, a market researcher surveyed 600 customers and found out that 73% of them own a car.

The parameter of interest is the population proportion and the study variable is "the number of customers that own a car out of 600".

Using the Central Limit Theorem you can approximate the distribution of the sampling proportion to normal:

p'≈N(p; $\frac{p(1-p)}{n}$ )

Where p' is the sample proportion

p is the population proportion and the mean of the distribution

$\frac{p(1-p)}{n}$ is the variance of the distribution

Then de standard deviation of the samplig proportion distribution is $\sqrt{\frac{p(1-p)}{n}}$

You can estimate it using the sample proportion:

$\sqrt{\frac{p'(1-p')}{n}} = \sqrt{\frac{0.73*0.27}{600} }=0.0181$

Using the same sample proportion but a sample size of n=150, the estimated standard deviation is:

$\sqrt{\frac{p'(1-p')}{n}} = \sqrt{\frac{0.73*0.27}{150} }=0.0362$

I hope it helps!

It takes a hose 5 minutes to fill a rectangular aquarium 11 inches long, 13 inches wide, and 14 inches tall. how long will it ta

Karolina [17]

Volume of 1st aquarium = 11 * 13 * 14 = 2002
volume of 2nd aquarium = 21 * 14 * 30 = 8820

if 5 minutes = 2002
1 minute = 2002\5 = 400.4

minutes to fill the 2nd aquarium is 8820/400.4 = 22.028(approximately)

Vitek1552 [10]

Answer:

0.9953, 3.3629<x<4.0371

Step-by-step explanation:

Given that slader the internal revenue service claims it takes an average of 3.7 hours to complete a 1040 tax form, assuming th4e time to complete the form is normally distributed witha standard devait of the 30 minutes:

If X represents the time to complete then

X is N(3.7, 0.5) (we convert into uniform units in hours)

a) percent of people would you expect to complete the form in less than 5 hours

= $100*P(x$

b) P(b<x<c) = 0.50

we find that here

c = 4.0371 and

b = 3.3629

Interval would be

$(3.3629, 4.0371)$
