Answer:
Red on the 5th draw = 0.0907
Step-by-step explanation:
The first to fourth selections are all the same.
Blue + white = 12 + 6 = 18
The total number of marbles is 11 + 12 + 6 = 29
P(~ red) for the first four times = (18/29)^4 = 0,1484
Now on the 5th time, the first red is 11/18
So the Probability is 0.1484 * 11/18 = 0.0907
Answer:
x = 8
Step-by-step explanation:
Formula for sum of interior angles is 180(n - 2)
For a 5 sided polygon the sum is;
180(5 - 2) =540°
The supplement of ∡ 59° = 180° - 59° = 121°
The supplement of ∡ 77° = 180° - 77° = 103°
The supplement of ∡ 66° = 180° - 66° = 114°
The supplement of ∡ 62° = 180° - 62° = 118°
The sum of the polygon is:
121° + 103° + 114° + 118° + (180 - 12x)° = 540°
456° + (180 - 2x)° = 540°
(180 -12x)° = 540° - 456° = 84°
12x = 180° - 84° = 96°
x = 96/12 = 8
The question is asking what is 15% of $300.
"of" means multiply, and 15% is the same as 0.15 (% means divide by 100), so you have
0.15 * $300 = $45.
Answer:
240 cm
Step-by-step explanation:
10 • 18 = 180
18 - 6 = 12
12 • 5 = 60/2 = 30
12 • 5 = 60/2 = 30
180 + 30 + 30 = 240
Answer:
B) Subtract 4 from both sides
Step-by-step explanation:
You do this so you can get x alone, which then shows you what the answer is
x=4
