3. ms. Johnson placed two different orders with TR's special item store. each order was for 40 jars with the circus logo imprint
denis23 [38]
1.The height is 6 inches ad the width (diameter) is 3 inches!
2. So the jars are Volume ≈  42.41 inches so each boy needs 200 / 42.41 which equals approximately 4.72 inches per jar. So if wach boys have half the amount of jars which is 20 you multiply 20 by 4.72 which is 94.4 inches for each boy!

The weight of a package of mints is believed to be normally distributed with mean 21.37 grams and standard deviation 0.4, i.e. X
nasty-shy [4]

Answer:

P(21

And using a calculator, excel or the normal standard table we have that:

P(-1.85

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".  

Solution to the problem

Let X the random variable that represent the weigths of a population, and for this case we know the distribution for X is given by:

X \sim N(21.37,0.4)  

Where \mu=21.37 and \sigma=0.4

Since the distribution for X is normal then we know that the distribution for the sample mean \bar X is given by:

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

We can find the probability required with the following z score formula:

z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}


And replacing we got:

P(21

And using a calculator, excel or the normal standard table we have that:

P(-1.85

Urgent, please help, I really appreciate (100 points)
ANTONII [103]

Answer:

3, 6, 9, 12 is not geometric

Step-by-step explanation:

A geometric progression has a common ratio r between consecutive terms.

3, 6, 9 , 12

has a common difference of 3 between terms and is arithmetic

1, 5, 25, 125

r = 5 ÷ 1 = 25 ÷ 5 = 125 ÷ 25 = 5 ← geometric

4, 8, 16, 32

r = 8 ÷ 4 = 16 ÷ 8 = 32 ÷ 16 = 2 ← geometric

2, 6, 18, 54

r = 6 ÷ 2 = 18 ÷ 6 = 54 ÷ 18 = 3 ← geometric
