A department store, on average, has daily sales of $21,000. The standard deviation of sales is $3600. On Tuesday, the store sold $16,230 worth of goods. Find Tuesday's z score. What is the percentile rank of sales for this day
Answer:
Tuesday's z-score was of -1.325.
The percentile rank of sales for this day was the 9.25th percentile.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
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 p-value, we get the probability that the value of the measure is greater than X.
A department store, on average, has daily sales of $21,000. The standard deviation of sales is $3600.
This means that [tex]\mu = 21000, \sigma = 3600[/tex]
On Tuesday, the store sold $16,230 worth of goods. Find Tuesday's z score.
This is Z when X = 16230. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{16230 - 21000}{3600}[/tex]
[tex]Z = -1.325[/tex]
Tuesday's z-score was of -1.325.
What is the percentile rank of sales for this day
This is the p-value of Z = -1.325.
Looking at the z-table, this is of 0.0925, and thus:
The percentile rank of sales for this day was the 9.25th percentile.

a. Cite two descriptive statistics.
b. Make an inference about the population of all investment managers concerning the average return expected on equities over the next 12 months.
c. Make an inference about the length of time it will take for technology and telecom stocks to resume sustainable growth.
Answer:
(A.)
21% selected health care as the sector most likely to lead the market in the next 12 months.
47% of managers classified themselves as bullish or very bullish on the stock market.
(B.)
The average return expected on equities over the next 12 months for equities was 11.2% for the population of investment managers.
(C.)
The length of time it will take for technology and telecom stocks to resume sustainable growth is estimated to be about 2.5 years by investment managers.

Steven earns extra money babysitting. He charges $40.50 for 6 hours and $54.00 for 8 hours. Enter an equation to represent the relationship. Let x represent the number of hours Steven babysits and y represent the amount he charges.
Answer:
6.75 * x =y
Step-by-step explanation:
In this question, for is a keyword here we can use to represent division. If he charges $40.50 for 6 hours, this means we can represent this as [tex]\frac{40.50dollars}{6 hours}[/tex] to calculate the amount babysitting costs for an hour. Our answer is then [tex]\frac{6.75 dollars}{1 hour}[/tex]. A similar division of $54.00 for 8 hours results in a calculation of [tex]\frac{54.00 dollars}{8 hours} = \frac{6.75 dollars}{1hour}[/tex]. This means that for each hour, he charges 6.75 dollars, the same amount of money each hour.
Given this information, we can say that an equation to represent this relationship would be that, to calculate the total money Steven earns, we can multiply 6.75 dollars by the amount of hours he works, as he earns 6.75 dollars for each hour, making our equation 6.75 * x =y, with y representing the total amount he charges.

This basically says "the nth term is found by computing math, aka evaluating some function, based on the (n-1)th term".
As an example, we could have a function that simply squares the input
Let's say we started at 5. It squares to 25 which in turns squares to 625, and so on. Each new term is based on the old term. Namely, we squared the old n-1 term to get the new nth term.

Jill calls a plumber to her house to fix the leaking faucets . The plumber charges a one-time fee of $50 plus an additional $35 per hour of labor. What are the independent and dependent variables
Answer:
independent=$50
dependent=$35X
Step-by-step explanation:
50 is the independent variable because it doesn't change.
35X is the dependent variable because it does change.
In this scenario, the independent variable is the number of hours of labor and dependent variable is the total cost.
The independent variable is the number of hours. It is the variable that we can control or change.
The dependent variable is the total cost charged by the plumber.
It depends on the number of hours of labor and is determined by the plumber's fee structure, which includes a one-time fee of $50 plus $35 per hour of labor.
The total cost is calculated based on the number of hours of labor, making it the dependent variable in this situation.

A store decreases the price of a sofa by 16% this month only, to $5200. What was the price before the
discount
9514 1404 393
Answer:
$6190.48
Step-by-step explanation:
The price is now 1 -16% = 84% of the original price (p).
$5200 = 0.84p
p = $5200/0.84 = $6190.48
The price before the discount was $6190.48.
Given the vectors u= <2, 1> and v= <5, 4>, determine the components of a vector represented by 2u - 3v
A.) <14, 15>
B.) <-6, -9>
C.) <-11, -10>
D.) <19, 14>
Answer:
C.) <-11, -10>
Step-by-step explanation:
Let's define how to work with vectors.
For two vectors:
V = <a, b>
W = <c, d>
The product of a scalar k and a vector is given by:
k*V = k*<a, b> = <k*a, k*b>
And the sum (or difference) of two vectors is given by:
V ± W = <a, b> ± <c, d> = <a ± c, b ± d>
Now that we know this, we can solve the problem.
Here we have the vectors:
u = <2, 1>
v = <5, 4>
then:
2u - 3*v = 2*<2, 1> - 3*<5, 4>
= <2*2, 2*1> - <3*5, 3*4>
= <4, 2> - <15, 12>
= <4 - 15, 2 - 12>
= < -11, -10>
Then the correct option is C.

Hope it helps you stay safe<3Resuelve el siguiente problema aplicado al sistema de ecuaciones, utilizando cualquiera de los tres métodos aprendidos: Sergio tiene $ 1.950 en monedas de $ 100 y de $ 50. En total tiene 24 monedas. Determina cuántas monedas son de $ 100 y cuántas de $ 50.
Answer:
Tiene 9 monedas de $50 y 15 monedas de $100.
Step-by-step explanation:
Sergio tiene $1950 en monedas de $100 y $50, entonces la primera ecuación es la siguiente:
[tex] 100x + 50y = 1950 [/tex] (1)
Ahora, en total tiene 24 monedas:
[tex] x + y = 24 [/tex] (2)
De la ecuación (2) tenemos:
[tex] x = 24 - y [/tex] (3)
Ahora introduciendo la ecuación (3) en la ecuación (1) y resolviendo para "y" nos queda:
[tex] 100(24 - y) + 50 y = 1950 [/tex]
[tex] 2400 - 100y + 50y = 1950 [/tex]
[tex] y = \frac{450}{50} = 9 [/tex]
Con la ecuación (3) podemos hallar el valor de "x":
[tex] x = 24 - 9 = 15 [/tex]
Por lo tanto, tiene 9 monedas de $50 y 15 monedas de $100.

Find the volume of this cone.
Round to the nearest tenth.
10ft
6ft
Answer:
301.6 ft³
Step-by-step explanation:
Volume of the cone = ⅓*πr²h
Where,
radius (r) = 6 ft
height (h) = √(10² - 6²) => Pythagorean theorem
h = √(100 - 36)
h = √64
h = 8 ft
Plug in the values
Volume = ⅓*π*6²*8
Volume = 301.6 ft³ (nearest tenth)
