Answer:
0.02683<x<0.133173
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = p ± z√p(1-p)/n
p is the proportion
z is the confidence interval at 95% confidence
n is the sample size
Since it is found that a sample of size 100 yields 8 defectives, the sample proportion p = 8/100 = 0.08
Given
n = 100
z score = 1.96
p = 0.08
1-p = 1-0.08 = 0.92
Required
95% confidence interval
Substitute the given parameters into the formula as shown;
CI = p ± z√p(1-p)/n
CI = 0.08 ± 1.96√0.08(0.92)/100
CI = 0.08 ± 1.96√0.0736/100
CI = 0.08 ± 1.96(0.027129)
CI = 0.08 ± 0.053173
CI = (0.08-0.053173, 0.08+0.053173)
CI = (0.02683, 0.133173)
Hence the 95% confidence intervals for the proportion of defective items is 0.02683<x<0.133173

Which calculation can be used to find 6% of 50?
Answer:
3
Step-by-step explanation:
We are required to find 6% of 50
To write it mathematically,
50 * 6%
Now, 6% can be rewritten as 6/100 because it tells us: '6 out of 100' and that is what percentage does
= 50 * [tex]\frac{6}{100}[/tex]
= [tex]\frac{300}{100}[/tex]
= 3
Hence, 6% of 50 is 3

Can Someone Evaluate This
Explanation:
Replace x with 4. Then use PEMDAS to simplify fully.
[tex]y = (14+x) \div 2\\\\y = (14+4) \div 2\\\\y = 18 \div 2\\\\y = 9\\\\[/tex]
When using PEMDAS, we evaluate the stuff in the parenthesis first. Afterward we divide.
Find the average rate of change of g(x)= -4x^3+1 from x= -4 to x = 1
Answer:
[tex]Rate = -52[/tex]
Step-by-step explanation:
Given
[tex]g(x) = -4x^3 + 1[/tex]
x = -4 to x = 1
Required
Determine the average rate of change
This is calculated using:
[tex]Rate = \frac{g(b) - g(a)}{b - a}[/tex]
Where
[tex]a = x = -4[/tex]
[tex]b = x = 1[/tex]
Calculating g(b):
g(b) = g(1)
If [tex]g(x) = -4x^3 + 1[/tex], then
[tex]g(1) = -4(1)^3 + 1[/tex]
[tex]g(1) = -4*1 + 1[/tex]
[tex]g(1) = -4 + 1[/tex]
[tex]g(1) = -3[/tex]
Calculating g(a):
g(a) = g(-4)
If [tex]g(x) = -4x^3 + 1[/tex], then
[tex]g(-4) = -4(-4)^3 + 1[/tex]
[tex]g(-4) = -4*-64 + 1[/tex]
[tex]g(-4) = 256 + 1[/tex]
[tex]g(-4) = 257[/tex]
So, the formula:
[tex]Rate = \frac{g(b) - g(a)}{b - a}[/tex]
becomes
[tex]Rate = \frac{g(1) - g(-4)}{1 - (-4)}[/tex]
[tex]Rate = \frac{g(1) - g(-4)}{1+4}[/tex]
[tex]Rate = \frac{g(1) - g(-4)}{5}[/tex]
[tex]Rate = \frac{-3 - 257}{5}[/tex]
[tex]Rate = \frac{-260}{5}[/tex]
[tex]Rate = -52[/tex]

Answer:
sin([tex]\frac{7\pi }{4}[/tex] ) = -[tex]\frac{\sqrt{2} }{2}[/tex]
Step-by-step explanation:
If cos(theta) = [tex]\frac{\sqrt{2} }{2}[/tex], then theta should equal [tex]\frac{\pi }{4}[/tex] or [tex]\frac{7\pi }{4}[/tex] since both angles are on the right side of the origin, meaning the cosine would be positive. However, it states that the angle theta terminates at quadrant IV so the only angle that would meet this criteria is [tex]\frac{7\pi }{4}[/tex] .
So theta should equal [tex]\frac{7\pi }{4}[/tex] .
Now that we have theta, all you have to do is find the value of sine by plugging it in.
sin([tex]\frac{7\pi }{4}[/tex] ) = -[tex]\frac{\sqrt{2} }{2}[/tex]

given r,s, and p, which angle is not congruent to 4?
Answer:
Line R, S, and P are parallel lines meaning any lines that pass through them will form the same angles. Look at 4 and 2. One line is intersecting S and P to for the same angles. Corresponding angles in parallel lines which are formed by an intersecting line are equal. Therefore 4 and 2 are equal. That leaves B, C, and D left. 4 is also congruent to 5. This is because if 4 is congruent to 2 and 2 is congruent to 5 by vertical angles theorem, 5 must be equal to 4 (transitive property of equality: is a=b and b=c then a=c)
That leaves B and D left. Notice the angle made at the very top left. Across from that unlabeled angle is 6. By vertical angles theorem those 2 angles are congruent. The unmarked angle is equal to 2 and 4 because corresponding angles in parallels are congruent. Therefore lets mark that unmarked angle as 0. If the m< 6 = m< 0 and the m<0= the m<4 then m<6 must equal the m<4.
That leaves Just B remaining thus B is NOT congruent to 4

A bowl of raffle tickets contains the numbers 1 through 60. What is the probability that a randomly selected ticket will be a number that is not a multiple of 7
Answer:
[tex]Probability = \frac{13}{15}[/tex]
Step-by-step explanation:
Given
Ticket Numbers = 1 to 60
Required
Determine the probability of not selecting multiples of 7
First, we need to list out the multiples of 7 in this range:
[tex]Multiple = 7,14,21,28,35,42,49,56[/tex]
These are 8 in numbers. So, there are 8 multiples
Next, is that we determine the number of non multiples of 7. This s calculated as:
[tex]Non\ Multiples = 60 - 8[/tex]
[tex]Non\ Multiples = 52[/tex]
The required probability is then calculated as:
[tex]Probability = \frac{Non\ Multiples}{Total}[/tex]
[tex]Probability = \frac{52}{60}[/tex]
[tex]Probability = \frac{13}{15}[/tex]
Answer:
Step-by-step explanation:
There are 8 numbers between 24 and 31, inclusive. So the probability of getting a number in that range is 885. Therefore, by the complement rule, the probability of not getting one of these numbers is
[tex]1-(8/85)= 85- 8 /85=77/ 85[/tex]

Answer:
1 and 7/30 minutes
Step-by-step explanation:
You know that the 3 commercials add up to 3 minutes of time. And that the first two are 1 1/6 minute and 3/5 minute. To add them you need a common denominator.
1 1/6=7/6. 7/6*5/5=35/30. 3/5*6/6=18/30. 35/30+18/30=53/30. 53/30 simplifies to 1 23/30 (don't need to simplify yet).Now, you need to subract that from 3. To write it over 30, multiply by 30/30. 3/1*30/30=90/30.90/30-53/30=37/30. 37/30 can be written as 1 7/30.given the area of a rectangle is 208 square inches, and given the length is 26 inches, find the width

x = 10 - y and y = x - 8
Answer:
x = 9 and y = 1
Step-by-step explanation:
Here,
x = 10 - y and y = x - 8 is given
then, name the equation
x = 10 - y ...(1)
y = x - 8 ...(2)
Now, put the value of x in equation (2) we get
y = x - 8
y = (10 - y) - 8
y = 10 - y - 8
y + y = 10 - 8
2y = 2
y = 2÷2
y = 1
Here, we get the value of y = 1
Now, we put the value of y in equation (1) we get
x = 10 - y
x = 10 - (1)
x = 10 - 1
x = 9
VERIFICATION:x = 10 - y
9 = 10 - 1
9 = 9
Hence, LHS = RHS

Mrs. Culland is finding the center of a circle whose equation
is x2 + y2 + 6x - 4y – 3 = 0 by completing the square. Her
work is shown.
x2 + y2 + 6x + 4y - 3 = 0
x2 + 6x + y2 + 4y - 3 = 0
(x2 + 6x) + (12 + 4y) = 3
(x2 + 6x + 9) + (y2 + 4y + 4) = 3 + 9 + 4
Which completes the work correctly?
(x - 3)2 + ( - 2)= 42, so the center is (3,2).
(x + 3)2 + (y + 2)2 = 42, so the center is (3, 2).
(x - 3)2 + (x - 2)2 = 42, so the center is (-3,-2).
(x + 3)2 + (y + 2)2 = 42, so the center is (-3, -2).
Answer:
centre of circle (h,k) is (-3,-2)
Option D is Correct.
Step-by-step explanation:
The centre of circle can be found from the equation as:
[tex](x-h)^2+(y-k)^2=r^2 \ then \ (h,k) \ is \ center[/tex]
So, the steps then by Mrs Culland are:
[tex]x^2 + y^2 + 6x + 4y - 3 = 0\\x^2 + 6x + y^2 + 4y - 3 = 0\\(x^2 + 6x) + (y^2 + 4y) = 3\\(x^2 + 6x + 9) + (y^2 + 4y + 4) = 3 + 9 + 4[/tex]
The next step will be:
[tex](x + 3)^2 + (y + 2)^2 = 16[/tex]
I assume there is some calculating mistake in the given options. Instead of 42 there should be 16, according to solution shown above.
The general equation of circle is
[tex](x-h)^2+(y-k)^2=r^2 \ then \ (h,k) \ is \ center[/tex]
In our case: [tex](x + 3)^2 + (y + 2)^2 = 16[/tex]
h= -3 and k= -2, so the centre of circle (h,k) is (-3,-2)
Option D is Correct.
Answer:
D,,,, (x+3)²+(y+2)²=4², so the center is (-3, -2).

If DEF is congruent to JKL, DE = 18, EF =23, DF = 9x-23, JL = 7x-11, and JK = 3y-21, find the values of x and y
Answer:
x = 6, y = 13Step-by-step explanation:
if DEF is congruent to JKL, this means that the sides of JKL are all equal to that of DEF.
Hence we can say;
DE = JK
EF = KL
DF = JL
Given
DE = 18,
EF =23,
DF = 9x-23,
JL = 7x-11
JK = 3y-21,
Required
Values of x and y
Since DE = JK;
18 = 3y-21
18+21 = 3y
39 = 3y
y = 39/3
y = 13
Also, DF = JL
9x-23 = 7x-11
collect like terms
9x - 7x = -11+23
2x = 12
x = 12/2
x = 6
Hence the value of x is 6 and y is 13
Given: [tex]DE=18[/tex],[tex]EF=23,DF=9x-23,JL=7x-11,[/tex] and[tex]JK=3y-21.[/tex]
As [tex]\Delta[/tex][tex]DE[/tex][tex]F[/tex] [tex]\cong[/tex] [tex]\Delta JKL[/tex]
[tex]\Rightarrow DE=JK \ ; EF=KL \ and \ DF=JL[/tex]
[tex]\Rightarrow 18=3y-21 \ ; 23=KL \ and \ 9x-23=7x-11[/tex]
[tex]y=13[/tex] ; [tex]KL=23[/tex] and [tex]x=6[/tex]
Therefore, [tex]x=6[/tex] and [tex]y=13[/tex]

After substituting, what is the first step when evaluating 7 when y = 8? Add 4 and 9. O Multiply 8 by 4. Divide 9 by 7. O Divide 4 by 7.
Note: you did not correctly enter the right expression. After a little research, I am able to find the correct expression which is as follows:
4y+9/7 when y = 8
Therefore, I am solving your query based on evaluating the expression
4y+9/7 when y = 8
Answer:
we conclude that after substituting, the first step is to 'Multiply 8 by 4'.
Step-by-step explanation:
Given the expression
4y+9/7
As we have to evaluate the given expression for the y=8
substituting y=8 in the expression
4y+9/7
= 4(8)+9/7
According to PEMDAS rule, we first need to do multiplication
Thus, the first step must have to be multiplying 4 and 8.
= 32 + 9/7
= 233/7
Therefore, we conclude that after substituting, the first step is to 'Multiply 8 by 4'.
