Answer:
<h3>
m∠2 = 67°</h3>
Step-by-step explanation:
m║n ⇒ (9x + 2)° = 74° {Corresponding Angles}
(9x)° = 72°
x = 8
Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)
(5×8 - 1)° + 74° + m∠2 = 180°
39° + 74° + m∠2 = 180°
113° + m∠2 = 180°
m∠2 = 180° - 113°
m∠2 = 67°
Answer: (0.63, 7.07)
Step-by-step explanation:
The confidence interval for population proportion is given by :-
Given :
; 
Significance level : 
Critical value : 
Now, a 90% confidence interval for population proportion will be :-
Hence, a 90% confidence interval for population proportion = (0.63, 7.07)
Answer:
1 lb. bag of cherries costs $3.55
Answer:
$325
Step-by-step explanation:
Let the dryer be x and the washer be y
x+y= 711---------1
y= x+61-----------2
put y= x+61 in 1
x+x+61= 711
2x+61= 711
2x= 711-61
2x=650
x= 650/2
x=325
Hence the dryer cost $325
