The stem and leaf plot here shows the current sale prices
for 60 houses in Horsham, PA, in thousands of dollars.
Note how the key helps communicate the prices.
Describe the distribution of housing prices.
Answers
Answer:
Symmetric
Step-by-step explanation:
In the stem and leaf plot above which represents the current sale prices of houses in dollars, we can observe the shape of the distribution seem like that of a bell shape. Most of the data values are concentrated towards the center compared to the concentration at both extremes.
This implies that most of the current sales price is centered close to the median price of roughly 49/50 dollars.
Therefore, the distribution of housing price can be described as roughly symmetric.

What is a solution for this inequality
Answers
Answer:
There are no solutions.
Step-by-step explanation:
3x+12>3(x+4)
Step 1: Simplify both sides of the inequality.
3x+12>3x+12
Step 2: Subtract 3x from both sides.
3x+12−3x>3x+12−3x
12>12
Step 3: Subtract 12 from both sides.
12−12>12−12

A change in pressure on the eardrum occurs when a pure musical tone is played. For some
tones, the pressure on the eardrum follows the sine curve
2/14
where is the pressure in pounds per square foot at time t second, and is the frequency of
the sound wave in cycles per second When p() is positive, there is an increase in pressure
and the eardrum is pushed inward: when p() is negative there is a decrease in pressure and
the eardrum is pushed outward.
(a) Graph the pressure on the eardrum for Middle C, which has a frequency of / 261.63
H. (ie, cycles per second), for between 0 and 0.005, i.e., [0, 0.005).
(1) Determine the period, denoted by 7 of p(6). What is the relationship between the period
and the frequency of the tone?
Answers
Answer:
a) see attached
b) period = 1/f ≈ 3.822 ms
Step-by-step explanation:
Apparently the pressure formula is ...
[tex]p(t)=0.004\sin{\left(2\pi ft+\dfrac{\pi}{7}\right)}[/tex]
__
a) A graph of this for f=261.63 is shown in the attachment.
__
b) The period is the time T required to change the sine function argument by 2π:
2πfT = 2π
T = 1/f . . . . . . divide by 2πf
The period is the reciprocal of the frequency.
The period of the tone is 1/(261.63 Hz) ≈ 3.822·10^-3 s
Employment statistics in the US are often based on two nationwide monthly surveys: the Current Population Survey (CPS) and the Current Employment Statistics (CES) survey. The CPS samples approximately US households and collects the employment status, job type, and demographic information of each resident in the household. The CES survey samples non-farm businesses and government agencies and collects the number of payroll jobs, pay rates, and related information for each firm.
a. What is the population in the CPS survey?b. What is the population in the CES survey?
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
The population in the CPS survey is
Total number of US households
The population in the CES survey is
Total number of nonfarm businesses and government agencies
Step-by-step explanation:
From the question we are told that
The number of US households sampled by CPS is 60 , 000
The number of nonfarm businesses and government agencies sampled by CES is 140,000
Generally population is defined as the universal set where the samples are drawn from
Hence the population of CPS survey is the total number of US households
And the population in the CES survey is the total number of nonfarm businesses and government agencies

Answers
Answer: The level of significance, , is the probability of committing a Type I error, rejecting the null hypothesis when it is, in fact, true.
Step-by-step explanation:
The significance level, which is commonly designated as alpha (α) is defined the probability of rejecting the null hypothesis when it is in fact, true.
To determine statistical significance, a researcher is expected to calculate a p-value. The researcher can reject the null hypothesis if the p -value is less than α as established by the researcher.

Solve the absolute value equation: |5x - 10| = |5x +25|
Answers
Answer: x=-3/2
Solve Absolute Value.
|5x−10|=|5x+25|
We know either5x−10=5x+25or5x−10=−(5x+25)
5x−10=5x+25(Possibility 1)
5x−10−5x=5x+25−5x(Subtract 5x from both sides)
−10=25
−10+10=25+10(Add 10 to both sides)
0=35
5x−10=−(5x+25)(Possibility 2)
5x−10=−5x−25(Simplify both sides of the equation)
5x−10+5x=−5x−25+5x(Add 5x to both sides)
10x−10=−25
10x−10+10=−25+10(Add 10 to both sides)

Helppp pls
Answers
Given that,
the two numbers are consecutive
The two numbers are
x and x + 1
Sum of the numbers = 81
x + (x + 1) = 91
x + x + 1 = 91
2x = 91 - 1
2x = 90
x = 90/2
x = 45
Therefore, the two numbers are x = 45 and x + 1 = 46
Mrs. Ross needs to buy dish soap. There are four differently sized containers. Sort the brands from least to the greatest unit price. Round each unit price to the nearest thousandth.
Answers
Answer: Spotless soap < Bright wash < Lemon bright < lot of suds
Step-by-step explanation:
Given that 8 oz of Lots of suds cost = $0.98
Then unit price of 1 lot of suds = 0.98/8 = $0.1225
Given that 12 oz of Bright wash cost = $1.29
Then unit price of 1 Bright wash = 1.29/12 = $0.1075
Given that 30 oz of Spotless soap cost = $3.14
Then unit price of 1 Spotless soap = 3.14/30 = $0.104666666667
Given that 32 oz of Lemon bright cost = $3.50Then unit price of 1 Lemon bright = 3.50/32 = $0.109375
We also need to round the values to the nearest thousandth means three digits after decimal
Then unit price of 1 lot of suds = $0.123
unit price of 1 Bright wash = $0.108
unit price of 1 Spotless soap = $0.105
unit price of 1 Lemon bright = $0.109
Now we can easily sort them
0.105 < 0.108 < 0.109 < 0.123
respective names in sorted order are:
Spotless soap < Bright wash < Lemon bright < lot of suds

There are 6 people at a party. if each person must shake hands with other every other person at the party exactly once how many handshakes will there be

If six people all shake hands with each other, how many hand shakes were made in total?
Publish your book. Become an author in 15 days. Get published.
I assume that no two people shake hands if they've already shaken them earlier, irrespective of who initiated it.
In that case Guest 1 will shake hands with 5 others (Guest 2 to 6)
Guest 2 will shake hands with 4 others (Remember she's already shaken hands with Guest 1).
Guest 3 will shake hands with 3 others (having already shaken hands with Guest 1 and 2)
and so on.....
