Answer:
The northern Georgia study with a margin of error of 1.7%.
All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)
Step-by-step explanation:
The best and most correct answer among the choices provided by the question is the third choice "The northern Georgia study with a margin of error of 1.7%."
All else being equal, the study with the larger sample size has the smaller margin of error. So the result makes sense (as 0.84 is pretty close to 0.75)

In rhombus ABCD shown below, AB=17 and AC=16 determine the length of BD without (hint , not with trigonometry)
Answer:
[tex]BD = 30[/tex]
Step-by-step explanation:
Given
[tex]AB = 17[/tex]
[tex]AC = 16[/tex]
See attachment
Required
Find BD
If AC = 16, then:
[tex]AO = 16/2[/tex] i.e. half the diagonal AC
[tex]AO = 8[/tex]
The diagonals of a rhombus are perpendicular.
This implies that we can apply Pythagoras theorem.
Using Pythagoras theorem on triangle AOB, we have:
[tex]AB^2 = AO^2 + OB^2[/tex]
[tex]17^2 = 8^2 + OB^2[/tex]
[tex]289 = 64 + OB^2[/tex]
Collect like terms
[tex]OB^2 = 289 - 64[/tex]
[tex]OB^2 = 225[/tex]
Take positive square roots of both sides
[tex]OB = 15[/tex]
To solve for BD, we use:
[tex]OB = \frac{BD}{2}[/tex] --- i.e. half the diagonal BD
[tex]BD = 2 * OB[/tex]
[tex]BD = 2 * 15[/tex]
[tex]BD = 30[/tex]

Step-by-step explanation:
4 cards have either take 3 cards or take two cards.
The other two are either play a card or lose a turn 4+2=6
4 over 6
simplified to 2 over three
or option D
Answer: The answer is D, 2/3
Step-by-step explanation: There are 6 sections the spinner can land on so that's the denominator. The numerator is the number of "Take Cards" there are. So the unsimplified answer is 4/6. Hope this helps!! :)

D 6 - 5x=9
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of maths,
here, A.) is correct because.
2/3(27) - 6 ==> 18 - 6 = 12
hence, LHS = RHS,
so option A is correct
An author works on a new book and after writing a few chapters, begins a new plan to write 600 words per day. On the fifth day of working on this plan, 4,500 words have been written. If the equation y = 600x + b represents the total number of words the author has written, y, based on the number of days, x, since the new plan was started, what is the value of b?

factorize 2x⁴+x³-14x²-19x-6
no spam and kindly explain your answer!
Step-by-step explanation:
Consider given the expression,
⇒2x4+x3−14x2−19x−6
⇒x3(2x+1)−(14x2+19x+6)
⇒x3(2x+1)−(14x2+7x+12x+6)
⇒x3(2x+1)−[7x(2x+1)+6(2x+1)]
⇒x3(2x+1)−(2x+1)(7x+6)
⇒(2x+1)(x3−7x−6)
Hence, this is the answer.
Maximum profit. A university student center sells 2,000 cups of coffee per day at a price of $4.0. A market survey shows that for every $0.1 reduction in price, 100 more cups of coffee will be sold. The cost of making one cup of coffee is $1.0. a) how much should the student center charge for a cup of coffee in order to maximize the profit? b) how many cups of coffee is the student center selling per day with this price? c) what is the maximum profit?
Answer:
a) $3.50
b) 2,500 cups
c) $6,250
Step-by-step explanation:
a) The number of cups of coffee the student sells, n = 2,000 cups
The price at which the student sells the coffee, P = $4.0
The number of extra cups sold for every $0.1 reduction in price = 100 cups
The cost of making one cup of coffee, C = $1.0
Let 'x' represent the set charge for a cup of coffee, we get;
The number of cups, nₙ = 2,000 + 100 × (4.0 - x)/0.1 = 6,000 - 1,000·x
Therefore, the revenue is given as follows;
Revenue, R = x × (6,000 - 1,000·x) = 6000·x - 1,000·x² = 1,000·(6·x - x²)
The cost, C = 1 × 6,000 - 1,000·x = 6,000 - 1,000·x
The profit, P = Revenue - Cost
∴ Profit = 6000·x - 1,000·x² - (6,000 - 1,000·x) = 7,000·x - 1,000·x² - 6,000
Profit, P = 7,000·x - 1,000·x² - 6,000 = 1,000 × (7·x - x² - 6)
At the maximum profit, we have; , we have;
dP/dx = 0
∴ dP/dx = d(1,000 × (7·x - x² - 6))/d
dR/dx = 1,000·d(7·x - x² - 6)/dx = 1,000 × (7 - 2·x) = 0
x = 7/2 = 3.5
The price that gives the maximum profit, x = $3.50
Therefore, the amount the student center should charge for a cup of coffee to maximize profit, x = $3.50
b) We have;
The number of cups, n = 6,000 - 1,000 × 3.5 = 2,500
The number of cups of coffee the student center sells at the price that gives the maximum profit, n = 2,500 cups
c) The maximum profit, [tex]P_{max}[/tex] = 1,000 × (7 × 3.5 - 3.5² - 6) = 6,250
The maximum profit, [tex]P_{max}[/tex] = $6,250.

Part B
Which of the following statements is true all that apply.
A.more males were surveyed than females.
B.more female like soccer.
C.An equal number of people like soccer and basketball.
D.Twice as many females than males like basketball
Answer:
Soccer: 19 Males
Basketball: 29 females
Total: 40 males, 60 females
Step-by-step explanation:
MALES FEMALES TOTAL
SOCCER ║ 19 ║ 31 ║ 50 ║
BASKETBALL║ 21 ║ 29 ║ 50 ║
TOTAL ║ 40 ║ 60 ║ 100 ║
[OPTIONS ⇒ 19, 29, 40, 60]
SOCCER:
x + 31 = 50
50 − 31 = 19
19 males
BASKETBALL
21 + y = 50
50 − 21 = 29
29 females
TOTAL:
F: 31 + 29 = 60
M: 19 + 21 = 40
60 + 40 = 100
60 females
40 males
