Answer:
The way I would write it is: 700,000 + 20,000 + 4,000= 724,000
Probability is the ratio of: the number of observations of an event n(A) compared to the total number of observation n(S). Generally it could be written as
P(A) =
Use combination to solve this problemThe event being observed n(A) in this problem is 2 engineers being selected from 4 engineers. The observation n(S) is about 2 people being selected from 10 people (engineers + pilots).
n(A) could be determined using combination of 2 engineers from 4 engineers
n(A) =

n(A) =

n(A) =

n(A) =

n(A) =

n(A) = 6
n(S) could be determined using combination of 2 people from 10 people
n(S) =

n(S) =

n(S) =

n(S) =

n(S) =

n(S) =

n(S) = 45
The probability
P(A) =

P(A) =

P(A) =
The probability is 2/15
Answer:
D. 264°
Step-by-step explanation:
When a tangent and a secant, two secants, or two tangents intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs. Therefore,
60° = 1/2[(18x - 6)° - (5x +17)°]
60° * 2 = (18x - 6 - 5x - 17)°
120° = (13x - 23)°
120 = 13x - 23
120 + 23 = 13x
143 = 13x
143/13 = x
11 = x
x = 11
(18x - 6)° = (18*11-6)°= (198 - 6)° = 192°
(5x +17)° = (5*11 +17)° =(55+17)° = 72°
m (arc KNL) = (18x - 6)° + (5x +17)° = 192° + 72°
m (arc KNL) = 264°
Answer: C
Step-by-step explanation:
Answer:
It will cost Alex $52.5 to make 12 pennants
Step-by-step explanation:
The area of the pennant is the area of the rectangular portion plus the area of the triangular portion.



The area of 12 pennants


If the fabric for the pennants costs $1.25 per square foot, then;
42 square feet will cost
dollars.
