Parker randomly pulled out a sock that was black form
his drawer. Without replacement, what is the
probability that Parker will randomly pull out a white
sock on his second pull?
Answer:
[tex]Probability\ that\ Parker'd\ pull\ off\ a\ White\ Sock(\ On\ His\ Second\ Pull)=\frac{6}{11}[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\Total\ number\ of\ Black\ Socks=7\\Total\ number\ of\ White\ Socks=12\\Total\ number\ of\ Navy\ Socks=4\\Hence,\\Total\ number\ of\ Socks\ Parker\ has=12+4+7=23\\We\ know\ that,\\The\ Random\ experiment\ here,\ is\ pulling\ out\ a\ white\ sock,\ after\ pulling\\ a\ black\ sock.\\Hence,\\Since\ the\ Black\ Sock\ had\ been\ removed\ from\ his\ drawer,\ the\\ number\ of\ 'Socks'\ that\ remain\ in\ his\ drawer=23-1=22\\[/tex]
[tex]Hence,\\Total\ elementary\ events\ for\ this\ random\ experiment=22\\Now,\\We\ just\ need\ to\ find\ out\ the\ probability\ of\ pulling\ out\ a\ 'White\ Sock'.\\Hence,\\Number\ of\ White\ socks=12\\Hence,\\Favorable\ number\ of\ elementary\ events\ for\ the\ Random\ Experiment=12[/tex]
[tex]We\ also\ know\ that,\\Probability\ for\ an\ Event\ A=\frac{Favorable\ No.\ of\ Elementary\ Events}{Total\ no.\ of\ elementary\ events}[/tex]
[tex]Hence,\\Probability\ that\ Parker\ would\ pull\ off\ a\ white\ sock\ on\ his\\ second\ pull=\frac{12}{22}=\frac{6}{11}[/tex]

3. Find the values of the constants in each of the following:
(1) f(x) = ax + b, a and b are constants, f2) = 7,f(1) = -1
9514 1404 393
Answer:
a = 8; b = -9
Step-by-step explanation:
Filling in the given values gives you two equations.
7 = a(2) +b
-1 = a(1) +b
Subtracting the second equation from the first gives ...
(7) -(-1) = (2a +b) -(a +b)
8 = a . . . . . simplify
Using this value in the first equation gives ...
7 = (8)(2) +b
b = 7 -16 = -9
The constants are a = 8, b = -9.
solve the following inequality: 55-5q > 4 (7-q)
Answer:
27 > q
Step-by-step explanation:
Solving an algebraic inequality is very similar to solving an algebraic equation, one uses inverse operations. One major difference between the two is that when one multiplies or divides an algebraic inequality by a negative number, one must remember to flip the inequality sign.
55 - 5q > 4 ( 7 - q )
Distribute,
55 - 5q > 28 - 4q
Inverse operations,
55 - 5q > 28 - 4q
+5q +5q
55 > 28 + q
-28 -28
27 > q

Answer: Carat
Step-by-step explanation:
It is given that 1 atomic unit is equivalent to
[tex]8.3\times 10^{-24}\ \text{carat}[/tex] and [tex]1.66\times 10^{-21}\ mg[/tex]
Express carat and milligram in the atomic mass unit, that is
[tex]1\ \text{amu}\equiv 8.3\times 10^{-24}\ \text{carat}\\1\ \text{carat}\equiv \dfrac{1}{8.3\times 10^{-24}}=1.204\times 10^{23}\ amu[/tex]
For milligram

give your answer in the form n:1
The cube root of 1331
(1331)^1/3 = 11
Reciprocal of 0.2 = 1 /0.2 = 5
Hence, the ratio Can be expressed as :

The length of a rectangle is 11 units more than its width. The perimeter of the
rectangle is 182 units. Solve for the dimensions of the rectangle. What is the
area of the rectangle?
9514 1404 393
Answer:
width: 40 unitslength: 51 unitsarea: 2040 square unitsStep-by-step explanation:
Let w represent the width of the rectangle. Then w+11 is the length. The perimeter is given by ...
P = 2(L +W)
182 = 2((w+11) +w)
182 = 4w +22 . . . . . simplify
160 = 4w . . . . . . . . . subtract 22
40 = w . . . . . . . . . . . divide by 4
40 +11 = length = 51 . . . . determine length
The dimensions of the rectangle are 40 × 51 units.
__
The area of the rectangle is ...
A = LW
A = (51)(40) = 2040 . . . . square units
The area is 2040 square units.
_____
Additional comment
The perimeter of a rectangle is double the sum of length and width, so that sum is 182/2 = 91 units. Now, this is a "sum and difference" problem, where the sum of length and width is 91, and the difference is 11. The solutions to such a problem are half the sum and half the difference of these numbers. Above, we found the smaller dimension (width) first: (91-11)/2 = 40. We could have found the length as (91+11)/2 = 51. The knowledge of the general solution to "sum and difference" problems often lets you work them with mental arithmetic.

An organization published an article stating that in any one-year period, approximately 10.3 percent of adults in a country suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, eight of them suffered from depression or a depressive illness. Conduct a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult population in the country.
Answer:
We accept H₀ we don´t have enough evidence to support that the proportion of certain town differs from that of National Information
Step-by-step explanation:
National Information:
p = 10,3 % p = 0,103
Sample
Sample size n₁ = 100
x₁ = 8
p₁ = x₁/100 p₁ = 8 / 100 p₁ = 0,08 %
q₁ = 1 - p₁ q₁ = 1 - 0,08 q₁ = 0,92
Confidence Interval CI = 95 % significance level α = 5 % α = 0,05
z(c) for α = 0,05 from z-table is : 1,64
Test Hypothesis:
Null Hypothesis H₀ p₁ = p
Alternative Hypothesis Hₐ p₁ < p
The alternative hypothesis suggest a one tail test to the left
z(s) = ( p₁ - p ) √p₁*q₁ / n₁
z(s) = ( 0,08 - 0,103 )/√ 0,08*0,92/100
z(s) = - 0,023 / 0,027
z(s) = - 0,85
Comparing z(s) and z(c)
z(s) > z(c) - 0,85 > -1,64
z(s) is in the acceptance region, we accept H₀

A process that is in control has a mean of 12.5 and a standard deviation of 1.1.
a. Construct the control chart for this process if samples of size are to be used (to 1 decimal).
For N=4
Find the UCL
Find the LCL
b. Repeat part (a) for samples of size and (to 2 decimals).
For N=10
Find the UCL
Find the LCL
For N=15
Find the UCL
Find the LCL
c. What happens to the limits of the control chart as the sample size is increased? Discuss why this is reasonable. and become - Select your answer (closerfarther) together as n increases. If the process is in control, the larger samples should have less variance and should fall - Select your answer (closerfarther) to 12.5
Answer:
1a) UCL = 14.2
LCL = 10.9
b) UCL = 15.63
LCL = 9.37
c) UCL = 16.48
LCL = 8.52
2) The difference between the limits falls close together as n increases
and the difference between the limits falls farther away from 12.5
Step-by-step explanation:
mean ( μ ) = 12.5
std ( б ) = 1.1
UCL = μ + ( n - 1 ) б / √n
LCL = μ - ( n - 1 ) б / √n
1) a) Given n = 4
UCL = 12.5 + ( 3 ) * 1.1 / 2
= 12.5 + 3.3/2 = 14.15 ≈ 14.2
LCL = 12.5 - 3.3/2 = 10.85 ≈ 10.9
b) Given n = 10
UCL = 12.5 + ( 9 ) * 1.1 /√10
= 12.5 + 3.13 = 15.63
LCL = 12.5 - 3.13 = 9.37
c) Given n = 15
UCL = 12.5 + 14 * 1.1 / √15
= 12.5 + 3.98 = 16.48
LCL = 12.5 - 3.98 = 8.52
2) As the sample size increases the difference between the limits of the control chart decreases
Hence the difference falls close together as n increases
and the difference between the limits falls farther away from 12.5

c. Find the i, j vector form of w.
d. Find the resultant vector of v+w. This includes its component form, magnitude and direction.

Answer:
a) v = 3i -6j
b) v ≈ 6.708∠-63.43°
c) w = -32.627i +15.214j
d) v+w = -29.627i +9.214j = 31.027∠162.72°
Step-by-step explanation:
Most graphing calculators and many scientific calculators can do arithmetic with vectors, often in the form of complex numbers or arrays. Of course, the usual conversions can be used:
(r; α) ⇒ (r·cos(α), r·sin(α))
(x, y) ⇒ (√(x²+y²); atan2(x, y))
where atan2(x, y) is arctan(y/x) quadrant-adjusted for the signs of x and y
__
a) v = 3i -6j
b) v ≈ 6.708∠-63.43°
c) w = -32.627i +15.214j
d) v+w = -29.627i +9.214j = 31.027∠162.72°

The first attachment shows the vectors and their sum in component form as complex numbers. For your purpose, the translation is ...
a +bi ⇒ ai +bj
The second attachment shows the vectors and their sum in polar form (magnitude and direction). I like the A∠B format. You may translate it to whatever form you need, for example, (A; B), A·cis(B), A(cos(B)i +sin(B)j), Ae^(iB), or any other. (The "semicolon format" is used by at least one app to distinguish between rectangular coordinates (a, b) and polar coordinates (A; B).) The angles here are in degrees (not radians), matching the form in the problem statement.

A fair die is rolled four times. Calculate the probability of obtaining exactly two 4s.
Answer:
The probability of getting two 4s is 5.55%.
Step-by-step explanation:
Since fair says is rolled four times, to calculate the probability of obtaining exactly two 4s the following calculations must be performed:
100/6 = 16.6666
0.166666 x 0.166666 = X
0.02777 = X
1 = 100
0.02777 = X
0.02777 x 100 = X
2.77 = X
2.77 x 2 = 5.55
Therefore, the probability of getting two 4s is 5.55%.
