Answer:
As such, in first quadrant, both the coordinates (x and y) are positive and both are negative in third quadrant. In second quadrant, y is positive and x is negative, while in fourth quadrant x is positive and y is negative, As (-4, -2) has both x and y coordinates negative, it will be found in third quadrant
Step-by-step explanation:

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]
9 divided by 8 is equal to 9 multiplied by _
Answer:
1/8.
Step-by-step explanation:
9/8 = 9x
Cross multiply:
9x * 8 = 9
72x = 9
x = 9/72 = 1/8.
CHECK the answer:
9/8 = 9 * 1/8 = 9/8.
Checks OK.
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

Find the simplified product: 2 square root 5x^3
Answer:
x Square root 5x
Step-by-step explanation:
f(x) = x2 What is g(x)?
A g(x)=3x^2
B g(x)= 1/3x^2
C g(x)= 1/9x^2
D g(x)= (1/3x)^2
Answer:
B g(x)= 1/3x^2
Step-by-step explanation:
In this question, we have that:
[tex]f(x) = x^2[/tex]
So, when [tex]x = 3, f(x) = f(3) = 3^2 = 9[/tex]
What is g(x)?
We have that [tex]g(x) = 3[/tex], when [tex]x = 3[/tex]
[tex]\frac{3}{9} = \frac{1}{3}[/tex]
This means that g is a third of f, and the correct answer is given by option B.
It is not d because the paranthesis is elevated, which means that (1/3)^2 = 1/9,
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%.

The sum of three consecutive numbers is 96. What are the smallest of these numbers? Write and Solve an Equation.
Answer:
30+32+34
Step-by-step explanation:
so 30 would be the smallest number. Hope this helps, have a nice day!
Answer:
31
Step-by-step explanation:
Remark
The easy way to set this up is to make the smallest number x - 1. You will see why in a moment. It cuts down on one step)
Equation
(x - 1) + x + (x + 1) = 96 Remove the brackets
Solution
x - 1 + x + x + 1 = 96 Combine like terms
3x = 96 Divide by 3
x = 32
Note: that is not the smallest number. Remember, the smallest number is x - 1
So the smallest number is 31

cube root 1331 : reciprocal of 0.2
give your answer in the form n:1
Answer:
2.2 : 1
Step-by-step explanation:
cube root 1331 : reciprocal of 0.2
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 :
11 : 5
In the form n : 1
divide both sides by 5
11/5 : 5 /5
2.2 : 1

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
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 map is drawn to the scale 1:4,000.
(a) The length of a road on the map is
3.5 cm. Find its actual length in meters.
Answer:
Original length of the road = 14,000 meter
Step-by-step explanation:
Given Scale;
1 cm = 4,000 meter
The length of road on map = 3.5 cm
Find:
Computation:
Original length of the road
Original length = Length on drawing x scale factor
Original length of the road = The length of road on map x scale factor
Original length of the road = 4,000 x 3.5
Original length of the road = 14,000 meter
