Answer:

Step-by-step explanation:

3.5 ( 11 ) = 38.5

1.9 ( 11 ) = 20.9

1.6 ( 11 ) = 17.6

38.5 + 20.9 + 17.6

= 77

The demand for a daily newspaper at a newsstand at a busy intersection is known to be normally distributed with a mean of 150 an

AURORKA [14]

Answer:

171 newspapers.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 150, \sigma = 25$

How many newspapers should the newsstand operator order to ensure that he runs short on no more than 20% of days

The number of newspapers must be on the 100-20 = 80th percentile. So this value if X when Z has a pvalue of 0.8. So X when Z = 0.84.

$Z = \frac{X - \mu}{\sigma}$

$0.84 = \frac{X - 150}{25}$

$X - 150 = 0.84*25$

$X = 171$

So 171 newspapers.

What 75% of two hundred

Ghella [55]

To find 75% of 200, we can multiply two fractions.

75/100 * 200/1

Now, just multiply the numerators and the denominators separately.

75 * 200 = 15000

100 * 1 = 100

Now, divide.

15000/100 = 150

There are 10 Superscript 9 bytes in a gigabyte. There are 10 Superscript 6 bytes in a megabyte. How many times greater is the st

ohaa [14]

To find the how many times greater is the storage capacity of a 1-gigabyte flash drive than a 1-megabyte flash drive we have to apply exponent operation.

The storage capacity of a 1-gigabyte is 1000 greater than 1-megabyte flash drive.

Given:

The given exponent for gigabyte is,

$10^9$

The given exponent of megabyte is,

$10^6$

<h3>What is exponent rule?</h3>

The power rule of exponent rule is defined as if raise the a number with exponent to power then we will mulitply exponent to the power times.
to change the negative exponent into a positive we have to invert the base.

Calculate the storage capacity.

$\dfrac{10^9}{ 10^6}=10^9-6}\\
\dfrac{10^9}{ 10^6}=10^3\\
\dfrac{10^9}{ 10^6}=1000$
