Answer:
The correct option is (i) I expect the confidence interval based on the sample of 64 data values to be more precise.
Step-by-step explanation:
Consider the provided information.
The sample size is inversely proportional to the standard error of the sample mean decreases. 
As the size increase the standard error of the sample mean decreases.
Hence, for greater precision select the confidence interval based on the greater sample of data.
Therefore, we expect the confidence interval based on the sample of 64 data values to be more precise.
The correct option is (i) I expect the confidence interval based on the sample of 64 data values to be more precise.
Answer:
x=5 and y=16
Step-by-step explanation:
x = number of pants
y = number of shirts
Set up equations:
- 25x + 14.5y = 357
- x + y = 21
Set the equations up as a system:
25x+14.5y=357
x+y=21
Steps:
Solve the system by substitution.
(You can also solve this system by elimination.)
<em>25x + 14.5y= 357</em>
<em>x + y = 21</em>
Step 1: Solve x+y=21 for x:
(x + y) − y = (21) − y(Subtract y from both sides)
x = −y + 21
Step 2: Substitute −y + 21 for x in 25x + 14.5y = 357:
25x + 14.5y = 357
25(−y + 21) + 14.5y = 357
−10.5y + 525 = 357 (Simplify both sides of the equation)
(−10.5y + 525) − 525 = (357) − 525(Subtract 525 to both sides)
−10.5y = −168
−10.5y / −10.5 = −168 / −10.5 (Divide both sides by -10.5)
y = 16
Step 3: Substitute 16 for y in x = −y + 21:
x = −y + 21
x = −16 + 21
x = 5 (Simplify both sides of the equation)
Answer:
x=5 and y=16
Answer:
x = 32
y = 51
m∠N = 14°
Step-by-step explanation:
Given:
ΔMNP ≅ ΔTUS
By the property of similarity,
MN ≅ TU, NP ≅ US and MP ≅ TS
m∠M = m∠T = 142°,
m∠N = m∠U = (2x - 50)°
m∠P = m∠S = 24°
Since, m∠N = [180°- (m∠M + m∠P)]
(2x - 50) = 180 - (142 + 24)
2x - 50 = 14
2x = 64 ⇒ x = 32
Since, NP = US,
2x - y = 13
2(32) - y = 13
64 - y = 13
y = 51
m∠N = 180° - (142 + 24)°
= 14°
Sure your smart Its just not your subject....School isn't my thing but you put me out into the woods and i could survive weeks with nothing...Lol just find your nitch and be proud of it
