Researchers are interested in learning more about the age of women when they marry for the first time so
they survey 500 married or divorced women and ask them how old they were when they first married. The
collection of the ages of the 500 women when they first married is a .............
A) Parameter B) Population C) Sample D) Statistic
Answer:
Option C: Sample
Step-by-step explanation:
We are told that a survey of 500 married or divorced women was carried out and they were asked how old they were when they first married.
Now, this survey represents a portion of the population. And a portion of the population surveyed is known as a Sample.
Thus, the correct answer is Option C
Rewrite in simplest terms: 9(2k – 3m) – 9m – 4(-3m - 3k)
Answer: 30k-24m
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

Step-by-step explanation:
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.
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

Example: Solve the equation 5(x+1)−(6x−9)÷3=20+x−6
Solution: First simplify expressions on both sides of the equation:
Use distributive property to open parenthesis: 5x+5−(2x−3) = 20+x−6
5x+5−2x+3 = 20+x−6
Combine like terms: 3x+8 = 14+x

Factored 16 out of the second term instead of 4
Did not apply the properties of exponents correctly
Factored 2 out of the first term instead of 4
Did not write the expression as division correctly
Answer:
Factored 16 out of the second term instead of 4
Did not apply the properties of exponents
Step-by-step explanation:
Given the expression :
8x^6 √200x^13 ÷ 2x^5√32x^7
STEP 1:
8x^6 √(25*4*2*(x^6)^2*x) ÷ 2x^5√16*2*(x^3)^2 *x
Step 2:
8*2*5*x^6√2x ÷ 2*4*x^5*x^3√2x[correct expression]
80x^12√2x ÷ 8x^8√2x
(80x^12√2x ) / (8x^8√2x)
10x^(12 - 8)
= 10x^4
The square root of 16 is 4 ;
Hence 4 should be factored out of the second term instead of 16
Answer: the mistake was in step 2 then: factored 16 out of the second term instead of 4

How do you solve 18x + 21y=204 and 6x + 14y=82
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

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.
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

Which amount is closest to Nathan's total costs after the 15% discount and including 6% sales tax? [Assume tax is applied after the discount is applied.]
Total price = $266.63 + $317.29+62.78=646.7
Discount = 15%
Discount amount = (15/100) x 646.7
=$97.005
Price after discount = $646.7 - $97.005
=$549.695
Sales tax = 6%
Sales tax amount =(6/100) x $549.695
=$32.9817
Total cost = Price after discount + sales tax amount
=$549.695 + $32.9817
=$582.6767
=$$582.68

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?
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.
