Answer:
about 65 percentage is the correct answer
Answer:
The answer to your question is:
Perimeter = 26.5 units
Area = 22.5 units²
Step-by-step explanation:
Data
A (5, 9)
B (8, 0)
C (0, 9)
Formula
d = 
dAB = 
dAB = 
dAB = 
dBC = 
dBC = 
dBC = 
dAC = 
dAC = 
dAC = 
Perimeter = 
Perimeter = 26.5 units
Area = 1/2 [ ( 5x0) + (8x9) + (0 x 9) - (5x 9) - (0x 0) - (8x9)]
= 1/2 [ 0 + 72 + 0 - 45 - 0 - 72]
= 1/2 [-45]
= 45/2
= 22.5 units²
The required sample size is 694.
Given a student wants to make a guess within 0.03 of the true ratio with a 95% confidence level.
Margin of Error, E = 0.03
significance level α=0.05 {95% confidence}
A given estimate of the percentage of population p is p = 0.79.
The critical value for the significance level α = 0.05 is Zc = 1.96. This can be determined using either Excel or a normal probability table.
Use the following formula to calculate the minimum sample size required to estimate the percentage of population p within the required margin of error.
n≥p(1-p)(Zc÷E)²
n=0.796×(1-0.796)(1.96÷0.03)²
n=693.1016
Therefore, the resample sizequired to meet the condition is n ≥ 693.1016 and must be an integer. From this, we conclude that the minimum sample size required is n = 694.

Answer:
its either 3 or 4
Step-by-step explanation:
Answer:
y = 27
Step-by-step explanation:
line segment BA and CD are congruent, turn them into an equation
3y - 59 = y - 5
subtract 1y from both sides, you get 2y - 59 = -5
then, add 59 to both sides and the equation is now 2y = 54
divide each side by 2 and you get the value of y (y = 27)
