Answer:
this mean amount of coffee to be dispensed would be 11.99, approximately 12
Step-by-step explanation:
first of all we have this information available to answer this question.
standard deviation σ = 0.006 ounces
prob(x > 12) = 0.04
we use this formular to find the mean
z = x - μ/σ
the value of the z score at 4% is equal to 1.7507
such that
we cross multiply from this stage
1.7507*0.006 = 12-μ
0.0105042 = 12-μ
μ = 12 - 0.0105042
herefore, the mean amount μ = 11.99 this can be approximated to 12

Answer:
85°
Step-by-step explanation:
So in geometry, the formula to find the <u>sum of all interior angles</u> is denoted as follows:
<em>n</em> = number of sides in the polygon
( <em>n</em> - 2 ) × 180° = sum of the interior angles
Using that formula, a triangle has 3 sides, so
<em>n</em> = 3 , therefore:
= ( 3 - 2 ) × 180°
= 1 × 180°
= 180°
Since the total sum of the interior angles of a triangle all have to add up to 180°, you can create the following equation and solve:
34° + 61° + <em>x</em> = 180°
Solve for x.
It's factorable when c ∈ {5,8,9}
If you Just divided -11u and 44 by -11 u equals 4
