Answer:
The critical value for the 90% confidence interval is 
.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
90% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
The critical value for the 90% confidence interval is .
140. If 150 in 1 case and double that is 300 for 2 cases which she uses everyday. 2 for everyday x a week is 7 x 2 = 14
John owns 64.17 percent (rounded to 64%). Sissy owns 34.45 percent (rounded to 34% or 34.5%).
Answer:
ANGLE K IS 75 DEGREES
All the interior angles of a triangle ADD up to 180 degrees
lets add the angles!
6x-11+8x-29+3x-1
add like terms. all the x terms add up and all the constants as well
8x+6x+3x = 17x
-29-1-11 = -41
17x-41= 180 (-41 + 41 = 0 we do this to remove -41 from the left side of the equation to isolate x)
41+180 = 221
17x=221
221/17 = 13
x=13
so..
8 * 13 - 29 is the angle..
8*13 = 104
and 104-29 = 75
Angle K is 75 degrees! hope that helps..
Step-by-step explanation:
Answer:
b = 10
Step-by-step explanation:
You can solve for b by dividing both sides by 1/5 because it will remove the 1/5 from the left side of the equation, but what you do to one side you must do to the other side as well.
(1/5b)/ (1/5) = 2/ (1/5)
b = 10
