Anarel [89]

Answer:

Upper P95 = 16.21in

Step-by-step explanation:

When the distribution is normal, we use 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 question, we have that:

\mu = 14.4, \sigma = 1.1

Upper P 95

This is the 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

Then

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

1.645 = \frac{X - 14.4}{1.1}

X - 14.4 = 1.1*1.645

X = 16.21

Upper P95 = 16.21in

Answer:

x = - 2, x = 7

Step-by-step explanation:

Given

f(x) = 4x² - 20x - 56

To find the zeros let f(x) = 0, that is

4x² - 20x - 56 = 0 ( divide through by 4 )

x² - 5x - 14 = 0 ← in standard form

(x - 7)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 7 = 0 ⇒ x = 7

HELP ME PLSSSSSS THIS IS HARD
Novosadov [1.4K]

Step-by-step explanation:

Given:

Function 'f' with two variables 'x' and 'y'.

To find:

Function rule if the parent function 'f' is rotated by 270° clockwise.

Solution:

A function given with two variables 'x' and 'y',

f(x,y) → (x, y)

If this function is rotated by 270° clockwise, the function rule will become,

f(x, y) → (-y, x)

Therefore, Option A will be the correct option.

<h3>What is Average number?</h3>

The total number of values in a given set divided by the sum of all the values is how an average is calculated. The arithmetic mean is another name for it. To get the average, let's look at some basic facts. The available values are 1, 2, 3, 4, and 5. Average is the total sum of all values or the total number of values.

<h3>According to the given information:</h3>

At any given time, the original business had an estimated average of 45 customers. According to the manager of the new store, on average 90 customers each hour—or 1.5 customers per minute—enter the establishment.

Additionally, the manager calculates that each customer spends an average of 12 minutes inside the shop.

According to Little's law, the new business has customers inside on average at all times.

, N=rt=(1.5)(12)=18

So,

= ((45−18)/45) ×100

=60

60 % less customers than the typical customer count in the original store at any given time
