Answer:
Importance of statistical inference, from population, without actual population distribution.
Step-by-step explanation:
Population contains all the units of group under consideration. Sample contains some selected units, to represent entire population group.
Yes, we can make statistical inferences about populations - without true population distribution. This can be done by hypothesis testing, using assumed population parameter & sample statistic.

5. Jon Metcalf signed a 253-day simple interest note for $7700 with a bank that uses exact interest. If the rate is 10 3/4% find the maturity value.
Answer:
8281.72
Step-by-step explanation:
Given:
Principal, P = 7700
Rate, r = 10 3/4 % = 43/4 % = 0.1075
Time, t = 253 days = 253/ 360
Using the relation :
A = P(1 + rt)
A = maturity value
A = 7700(1 + 0.1075*253/360)
A = 7700(1 + 0.0755486)
A = 7700(1.0755486)
A = 8281.7243
A = 8281.72

the sum of digits of two digit number is 6 when we interchange the digits it is found that the resulting number is greater than the original number by 18. what is the two digit number?
Answer:
24
Step-by-step explanation:
Original Number :-
Given that ,
Sum of digits is 6 .Let ,
Tens place = x Units place = 6 - xNumber ,
10x + 6 - x = 9x + 6On interchanging the digits :-
Tens place = 6-x Units place = x→ Number = 10( 6-x) + x
→ Number = 60 - 10x + x
→ Number = 60 - 9x
According to Question,
→ 9x + 6 + 18 = 60 - 9x
→ 18x = 60 - 24
→ 18x = 36
→ x = 36/18
→ x = 2
N = 9x + 6 = 18+6 = 24 Hence the required answer is 24.
Suppose you save $1 the first day of a month, $4 the second day, $16 the third day, and so on. That is, each day you save four times as much as you did the day before. What will you put aside for savings on the seventh day of the month?
Answer:
$ 4096 on the 7th day
Step-by-step explanation:
From the amount earned for the first 3 days it's 1 , 4 , 16 , .... We realize it increases exponentially.
So therefore:
Day 1 =4⁰
Day 2=4¹
Day 3=4²
Day 4=4³
Day 5=4⁴
Day 6=4⁵
Day 7=4⁶
Therefore on day 7 he saves 4⁶ which is $4096

A coin is tossed twice. Let Z denote the number of heads on the first toss and W the number of heads on the second toss. If the coin is unbalanced and a head has a 40% chance of occurring, find
Answer:
0.64
Step-by-step explanation:
Prob ( Head ) = 40% = 0.4 , Prob ( Tail ) = 1 - 40% = 60% = 0.6
4 outcomes = (Head Tail) , (Tail Head) , (Head Head) , (Tail , Tail)
Prob (Atleast one head) = Pr (Head Tail) + Pr (Tail Head) + Pr (Head Head)
(0.4) (0.6) + (0.6) (0.4) = 0.24 + 0.24 + 0.16 = 0.64
A chemist mixes 25 milliliters of a solution that is 44% acid with 225 milliliters of pure acid.
(a) How many milliliters of acid are in the resulting
mixture?
milliliters
(b) What percentage of the resulting mixture is acid?
Answer: a) 236 ml b) 94.4 %
Step-by-step explanation: a) in 44 % solution there is 0.44 · 25 ml = 11 ml.
Total volume of acid is 225 ml + 11 ml = 236 ml
b) vol-% of acid is 236 ml /(225 ml + 25 ml) · 100 % = 94.4 %
The milliliters of acid that are in the resulting mixture is 236 millimeters and the percentage of the resulting mixture is acid is 94.4%.
a. The milliliters of acid are in the resulting mixture will be:
= 225 ml + (44% × 25ml)
= 225ml + (0.44 × 25ml)
= 225ml + 11ml
= 236ml
b. The percentage of the resulting mixture that is acid will be:
= [(236ml / (25ml + 225ml)] × 100
= (236ml/250ml) × 100
= 94.4%

Answer:
13
Step-by-step explanation:
starting equation is 15=0.75(x)+5.
You have to have the numbers on one side so...
15-5=10, and 5-5=0.
now, our equation is 10=0.75(x).
we are looking for x, so....
10/.75= 13 and 1/3.
since there is no such thing as a third of a song, 13 would be our number.

The Law of Sines tells you ...
g/sin(G) = h/sin(H)
g = h(sin(G)/sin(H)) = 510 in(0.42262/0.84805)

Answer: B, D, and F
Step-by-step explanation:
Hi, so for this question, the phone bill is in an equation. Before doing this problem, make sure to understand what the 2 and 56 mean. The problem says that c is the monthly charge, and m is the number of minutes. This means that 2 is the number of dollars required to pay when you use the phone for one minute. So 2 dollars per minute. The 56 is basically the fee that is just charged for using the phone bill. Meaning that even if you don't use the phone at all, you will still need to pay 56 dollars.
By understanding those info, it should be easier to answer.
For A, it is not correct. if you look, although 2*4 is 8 dollars, but you need to add 56 for the monthly bill. (I think when they say 'your bill' they mean the monthly bill).
For B, it is correct. Like I said before, the 56 dollars is there no matter how long you use the phone.
For C, it is not correct. This isn't hard to understand since if B is correct, C is probably not, and vise versa. And the 56 dollars is missing.
For D, it is correct. As I said before, the 2 represents the amount of dollars for one minute.
For E, it is not correct. (Contradicts the previous answer and each minute costs 2 dollars).
For F, it is correct. When you use 2 minutes, the equation is 2*2+56 which is 60 dollars.
Hopefully this helps!

G is true is out divide 1/7 by 2 out get 1/14
H is false the product is always 1
I is false all numbers have a reciprocal besides 0
Answer:
g. True
h. False
i. False
Step-by-step explanation:
g.
[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]
This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]
If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]
The numerator is 1 * 1 which is 1
And then the denominator is 7 * 2 which is 14
That would give you [tex]\frac{1}{14}[/tex]
h.
The products of two reciprocals is 0
This is not true
Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.
Ex: [tex]\frac{2}{8}[/tex]
Its reciprocal is [tex]\frac{8}{2}[/tex]
So multiply them together
[tex]\frac{2}{8}* \frac{8}{2}[/tex]
2 * 8 = 16
8 * 2 = 16
[tex]\frac{16}{16} = 1[/tex]
i.
A whole number does not have a reciprocal
This is incorrect. If you think about it, a whole number is just the number, over 1
Ex: [tex]\frac{6}{1}[/tex]
This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.
If you an write it as a fraction, it has a reciprocal.
The reciprocal in this case would be [tex]\frac{1}{6}[/tex]

Curve is concave downward when the second derivative is negative.
y' = [tex]\frac{x^{2} }{x^{2} -x+4}[/tex] , by the Fundamental Theorem of Calculus
y'' = [tex]\frac{-x^2+8x}{\left(x^2-x+4\right)^2}[/tex] , which has a denominator that is always positive. The numerator [tex]-x^2+8x[/tex] is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.

Based on the density graph below, what is the probability of a value in the sample space being anywhere from 10 to 25?
A. 80% B. 60% C. 40% D. 20%
The probability of the sample from 10 to 25 will be 60%. Then the correct option is B.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
Based on the density graph below.
Then the probability of a value in the sample space being anywhere from 10 to 25 will be
P = (25 - 10)/(25 - 0)
P = 15/25
P = 0.6
P = 60%
Thus, the probability of a value in the sample space being anywhere from 10 to 25 will be 60.
Hence the correct option is B.

Find the measure of each angle indicated (quadrilaterals)
I think it’s 100 I just wanna make sure if it is
Find the measure of each angle indicated.
○ 44°
○ 68°
○ 59°
○ 100°
____________________Solution :-Given Information :-∠S = 95° ∠T = 85° ∠Q = 80° To Find :-The measure of ∠R Formula Used :-Sum of all angles of a Quadrilateral = 360° Calculation :-We will simply substitute the given values in the formula,
⇒ Sum of all angles of a Quadrilateral = 360°
⇒ ∠S + ∠T + ∠Q + ∠R = 360°
Substituting the values given, We get,
⇒ 95° + 85° + 80° + ∠R = 360°
Calculating further, We get,
⇒ 260° + ∠R = 360°
Transposing 260° to Right Hand Side, We get,
⇒ ∠R = 360° - 260°
Calculating further, We get,
⇒ ∠R = 100°
∴ ∠R = 100°
____________________Final Answer :-The measure of ∠R is 100°
Hence, Last option i.e., 100° is correct answer.
