150 families in Metropolis yield the accompanying data on length of residence in current homes. What is a point estimate for the mean of the sampling distribution of the difference between the 2 sample means?
Answers
Answer:
B. -15
Step-by-step explanation:
The question is incomplete, find the complete question attached. The point estimate of the mean is also known as the mean of the towns
Given the mean of two towns
xbarG for sample mean of Gotham = 35
xbarM for sample mean of Metropolis = 50
distribution of the difference between the 2 sample means = xbarG - xbarM
distribution of the difference between the 2 sample means = 35-50
distribution of the difference between the 2 sample means = -15
Hence option B is correct

Explanation:
For any 45-45-90 triangle, the two legs are the same length.
So m = n.
This is because the two angles opposite these legs are congruent.
Using the Pythagorean theorem, we can find m
m^2+n^2 = (7*sqrt(2))^2
m^2+m^2 = 98
2m^2 = 98
m^2 = 98/2
m^2 = 49
m = sqrt(49)
m = 7
As a quick shortcut, the hypotenuse of any 45-45-90 triangle is always sqrt(2) times the leg.
hypotenuse = (leg)*sqrt(2)
The answer to question is m=7.
How many different passwords of length 10 can be formed using 2 letters (A,...,Z) and 8 digits (0,1,...,9)
Answers
Answer: 67600000000
Step-by-step explanation:
The password has length 10 characters using 2 letters (A,...,Z) and 8 digits (0,1,...,9).
Total letters = 26
Total digits = 10
If repetition is allowed, then the number of different passwords of length 10 can be formed = [tex](26)^2\times (10)^8=67600000000[/tex]
Hence, the different passwords of length 10 can be formed = 67600000000

Based on what you have read, choose each response below that correctly describes the impact of the Glorious Revolution and the English Bill of Rights upon the colonies.
The colonies gained their independence from England.
The Dominion of New England was overthrown.
Colonists no longer had a king and queen.
Colonists were shown that an unjust king could be overthrown.
The idea that citizens have rights that government cannot take away gained more support.
Answers
Answer:B,ED
Step-by-step explanation:The Glorious Revolution affected the colonies by resulting in the dissolution of the Dominion of New England and caused a rebellion against the Catholic leaders of Maryland. Furthermore, the new regime in England began to treat the colonies with "salutary neglect." Instead of micromanaging colonial affairs, the crown and Parliament allowed the colonies to do more or less as they wished.
The Dominion of New England was overthrown, Colonists were shown that an unjust king could be overthrown, The idea that citizens have rights that government cannot take away gained more support. Option (b) (d) and (e) are correct.
What is Revolution?Revolutions take the shape of coordinated movements intended to bring about change—whether it is in the realms of economics, technology, politics, or society. The initiators of revolutions have come to the conclusion that the social institutions that are now in place have failed or are no longer necessary.
In the years following the revolution, Parliament's role and power underwent a significant transformation. The 13 North American colonies were impacted by the incident as well. After King James was deposed, the colonists were temporarily exempt from stringent, anti-Puritan legislation.
The Glorious Revolution (1688–1689) marked the transition from an absolute monarchy to a constitutional monarchy by permanently establishing Parliament as the governing body of England and, later, the United Kingdom.
Therefore, Option (b) (d) and (e) are correct. The Dominion of New England was overthrown, Colonists were shown that an unjust king could be overthrown, The idea that citizens have rights that government cannot take away gained more support

A conical tank (with vertex down) is 12 feet across the top and 18 feet deep. If water is flowing into the tank at a rate of 18 cubic feet per minute, find the rate of change of the depth of the water when the water is 10 feet deep.
Answers
Answer:
Step-by-step explanation:
Volume of a cone V = 1/3πR²h
r is the radius
h is the height
Given
dV/dt = 18ft³/min
h = 10ft
dimeter = 12ft
radius = 6ft
according to similar triangles
R = 6/10 h
R = 3/5 h
The volume becomes
V = 1/3πR²h
V = π/3(3h/5)²h
V = π/3 9h²h/25
V = 9h³π/75
dV/dt = dV/dh * dh/dt
dV/dt = 27h²π/75dh/dt
Substitute the given values
18 = 27(10)²π/75dh/dt
18 = 2700π/75dh/dt
18 = 36π dh/dt
dh/dt = 18/36π
dh/dt = 1/2π
dh/dt = 1/2(3.14)
dh/dt = 1/6.28
dh/dt = 0.1592ft/min
How do you solve 18x + 21y=204 and 6x + 14y=82
Answers
Answer:
x=9, y=2
Step-by-step explanation:
there are multiple ways to solve. I prefer lining both equations up so
18x + 21y =204
6x + 14y = 82
You can multiply 6x +14y =82 by -3 to get -18x + -42y = -246
then add both equations together to get y by itself. so you get
-21y=-42
y = 2
then substitute y back in to either equation and you'll get x=9

Step-by-step explanation:
so 9(2k-3m), there is an invisible multipulaction sign between the 9 and the parenthesis which means you have to multiply everything in there. 18k-27m.
Then -9m+12m+12k. Its a plus because two minuses make a positive.
18k-27m-9m+12m+12k. Now you put like terms together.
18+12k=30k, -27m-9m+12m= -24m
30k-24m

Tiffany and her friends are having lunch at Russell's Diner. The total cost of their lunch
including tax, is $54.63. Tiffany and her friends have $65.00 altogether and want to leave
a tip equal to 15% of the total bill. Is $65 enough to cover the cost of their lunch and the
15% tip for the server?
Answers
Answer:
Yes!
Step-by-step explanation:
If we want to find out if they have enough to pay for the meal and tip then we need to do 115% of 54.63
[tex]1.15*54.63=62.8245[/tex]
Since this is money we are talking about we need to round to the nearest hundredths place
[tex]62.82[/tex]
Since the bill with tax plus the tip is only $62.82 and they have $65 then they can afford to tip 15% and pay for the meal.
