Answer:
19.75%
Step-by-step explanation:
Since we are trying to find the probability for a sequence of events then we need to multiply the probability of each event happening separately from each other. Since the probability of it raining on a single day is 2/3 we need to multiply this value with itself 4 times (one for each day).
2/3 * 2/3 * 2/3 * 2/3 = 16/81 or 0.1975 or 19.75%
Therefore the probability would be 16/81 or 0.1975 or 19.75%
The sum of n terms is given from the first term and the common ratio by
For your given values of a1=-11, r=-4, n=8, the sum of 8 terms is
Answer: -2.5
Step-by-step explanation:
Answer:
63 cm^2
Step-by-step explanation:
For finding the area, split the given figure into 2 rectangles one with dimensions 6×5 and another with dimensions 12×2
Area = 6×5 + 12×2 = 39+24 = 63
A straight line is 180°. So you can do:
(15x - 4) + (5x - 8) = 180 Simplify
20x - 12 = 180
20x = 192 Find the value of x
x = 9.6
m∠ABD = 15x - 4 Plug in x = 9.6
m∠ABD = 15(9.6) - 4 = 144 - 4 = 140°
m∠DBC = 5x - 8 Plug in 9.6
m∠DBC = 5(9.6) - 8 = 48 - 8 = 40°
