Answer:
Hence option C is correct...hope this helps you:)
Answer:
Step-by-step explanation:
m∠EBC = 45°
3x + 9y = 45
Divide the entire equation by 3
x + 3y = 15 --------------------(I)
m∠EAB = 45
5x + 5y = 45
Divide the entire equation by 5
x +y = 9 -------------(II)
Multiply equation (II) by (-1)
(I) x + 3y = 15
(II)*(-1) <u> - x - y = -9</u> {Now add}
2y = 6
y = 6/2
y = 3
Plugin y = 3 in equation (I)
x + 3*3 = 15
x + 9 = 15
x = 15 - 9
x = 6
The percentage error is 11.1%
<h3>What is percentage error?</h3>
Percentage error is simply the difference between the exact and the estimated values as a percentage
The given parameters are:
The percentage error is then calculated as:

Evaluate the difference

So, we have:


Hence, the percentage error is 11.1%

Answer:
Step-by-step explanation:
Given that population average is 0.8 ampere
Sample size = 9
Sample mean x bar = 1.34 A
Sample std dev s = 0.48

(one tailed test)
Mean difference - 
Std error = 
t test can be used since sigma is not known and sample size small
t statistic = mean diff/std error = 3.5
df = 8
p value = 0.00404
Answer:the answers are: 0,1 and 2,7 and 4, 14
Step-by-step explanation:
Switch them if not in the right order, one of them is 2,7 because one of the dots are in between 6 and 8
