Which of the followinmg estimates at a 95% confidence level most likely comes from a small sample?
A. 71% (±18%)
B. 60% (±4%)
C. 62% (±6%)
D.65% (±2%)
Answers
Answer:
A. 71% (±18%)
Step-by-step explanation:
Based on the confidence interval relation :
Mean ± Margin of error
The mean could be any given value :
However, the margin of error at a given confis nce level will will affected by the sample size, larger sample sizes will result in smaller margin of error values as the it will result in a large value denominator hence giving a small margin if error value when divided.
Margin of Error = Zcritical * σ/√n
Since.weve been told that the sample size is small, this will result in a large error margin value, from the options given, the value with the largest error margin value will be produced by the smallest samole size. Hence the option with the largest error margin value is ; ±18%

(x − 8) and (x − 3)
Answers
Answer:
D
Step-by-step explanation:
one way to write a quadratic equation is using the y = (x-s) (x-r) where r and s are positive zeros. another way to solve this and think about it would be to plug in your points and equate both sides.
example:(3,0) (8,0)0 = (3-8) (3-3)0 = 00 = (8-8) (8-3)0=0

m∠B = 111º
Step-by-step explanation:
use law of cosines
c² = a² + b² - 2ab*cosC
---------------------------------
15² = 7² + 11² - 2(7)(11)cosB
225 = 49 + 121 - 154cosB
225 = 170 - 154cosB
Subtract 170 form both sides
55 = -154cosB
Divide both sides by -154
-0.3571428571 = cosB
m∠B = arccos -0.3571428571
use calculator
m∠B = 110.924832425009406
Rounded
m∠B = 111º

Find the measure of angle 6.
Answers
Answer:
85°
Step-by-step explanation:
the two lines that have red arrows on them are parallel and are cut by a transversal so angle 6 and the 95° angle are same side interior angles so they are supplementary angles so they need to add to 180°
∡ 6 = 180-95 = 85°
Find the area of the given trapezoid:
A = ...... square units
Answers
Answer:
A = 48 square units
Step-by-step explanation:
The dimensions between two markings on the coordinate plane = 2 unit
The trapezoid is located sideways
The area of a trapezoid, A = ((a + b)/2) × h
Where;
a = The long base side
b = The short base side
h = The height
The long base side length AT = 4 space between markings = 4 × 2 units = 8 units
The short base side length SR = 2 space between markings = 2 × 2 units = 4 units
The height, h = 4 space between markings = 4 × 2 units = 8 units
The area of the trapezoid, A = ((4 unit + 8 unit)/2) × 8 unit = 48 square units.
