Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08
Consider the equation:
X2+ 2x – 15 = 0
A) First, use the "completing the square" process to write this equation in the form
(2 + D)2= E
Answer:
x² + 2x - 15 = 0
x² + 2x + 1 = 16
(x + 1)² = 16
You can then go forward with that to solve it:
x + 1 = √16
x = -1 ± √16
x = -1 ± 4
x = 3, -5

Answer:
i have find the value of x and y in above figure hope it helps
The y-coordinate that represents the solution to the system of equations is 4
The equations are given as:
[tex]-x+y=1[/tex]
[tex]3x-y=5[/tex]
Make x, the subject in the first equation
[tex]-x+y=1[/tex]
[tex]x = y - 1[/tex]
Substitute y - 1 for x in the second equation
[tex]3x-y=5[/tex]
[tex]3(y - 1) - y = 5[/tex]
Open the brackets
[tex]3y - 3- y = 5[/tex]
Collect the like terms
[tex]3y - y = 5+3[/tex]
Evaluate the like terms
[tex]2y = 8[/tex]
Solve for y
[tex]y = 4[/tex]
Hence, the y-coordinate is 4

A supervisor records the repair cost for 22 randomly selected VCRs. A sample mean of $75.50 and standard deviation of $18.07 are subsequently computed. Determine the 99% confidence interval for the mean repair cost for the VCRs. Assume the population is approximately normal.
Answer:
The 99% confidence interval for the mean repair cost for the VCRs
(65.801, 85.199)
Step-by-step explanation:
Explanation:-
Mean of the sample(x⁻) = $75.50
Given the standard deviation of the sample (S) = $18.07
Given the size of the sample 'n' = 22
Degrees of freedom = n-1 =22-1 =21
critical value t₍₀.₀₁, ₂₁₎ = 2.5176
The 99% confidence interval for the mean repair cost for the VCRs
[tex](x^{-} - t_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} +t_{0.01} \frac{S.D}{\sqrt{n} })[/tex]
[tex](75.50 - 2.5176 \frac{18.07}{\sqrt{22} } , 75.50 +2.5176 \frac{18.07}{\sqrt{22} })[/tex]
( 75.50 - 9.699 , 75.50 + 9.699 )
(65.801, 85.199)
Final answer:-
The 99% confidence interval for the mean repair cost for the VCRs
(65.801, 85.199)

(») 1. Write a compound inequality for the graph.

6 help neededddd!!
Answer:
-2 < x ≤ 6
Step-by-step explanation:
This graph shows conjunction. This means that the two statements of the inequality bare true at the same time. Therefore, it follows that:
x > -2 ("we use greater than" because the empty/unshaded circle indicates that -2 is not included)
And
x ≤ 6 (we use greater than or equal to because the shaded circle indicates 6 is included)
Joining both statements together, we would have:
-2 < x ≤ 6
The largest species of jellyfish is the lion's mane jellyfish. One particular specimen has a diameter of 1.03 meters and tentacles that are 29 meters long. The specimen weighs 164 kilograms and can travel at a speed of 1.38 meters per second.
What is the diameter of the specimen in centimeters?
Answer:
The diameter of the specimen in centimeters is 103 cm.
Step-by-step explanation:
In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:
1.03 x 100 = X
103 = X
Therefore, the diameter of the specimen in centimeters is 103 cm.

Answer:
0.8 gallons per second
Step-by-step explanation:
Given that :
Filling occurs at a constant rate ;
Change in gallon of water in pool within a 3 seconds time interval ;
Assume :
At t = 0 ; gallons = 5
At t = 3 ; gallons = 7.4
Chanhe in gallons with time.;
(7.4 - 5) / (3 - 0)

Write your answer without negative exponents.
Answer:
-5/ (x^19 * y^12)
Step-by-step explanation:
-15x^-10 * y ^ -3 * x^-9 * y^-9/3 (It's writing it like this.)
15 and 3 have a GCF of 3.
-5x^-10 * y^-3 * x^-9 * y^-9/1
Reduce similar occurrences. *twice in a row*
-5x^(-10 + (-9)) * y^(-3 + (-9))/1
Remove extra signs *twice in a row*
-5x^(-10 - 9) * y^(-3 - 9)/1
Remove extraneous 1.
-5x^(-10 - 9) * y^(-3 - 9)
Add integers.
-5x^-19 * y^-12
Negative powers change multiplication to division.
-5 / (x^19 * y^12) is the final answer.
Even with that, the simplified answer wouldn't have negative exponents because of the negative powers rule.
