Answer:
B. 0.03110
Step-by-step explanation:
Given
Probability of Hit = 60%
Required
Determine the probability that he misses at 6th throw
Represent Probability of Hit with P
Convert to decimal
Next; Determine the Probability of Miss (q)
Opposite probabilities add up to 1;
So,
Substitute 0.6 for p
Next,is to determine the required probability;
Since, he's expected to miss the 6th throw, the probability is:
Hence;
<em>Option B answers the question</em>
Answer:
Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4
1) Multiply 12 by 4.1.
2) Divide 49.2 by 2.
3) Multiply 24.6 by 9.
Hey there!!
Closely observe the triangle, the triangle given is a isosceles triangle , hence, the angles on the base would be equal and hence, angle R = 3x + 30
The sum of all angles in a triangle = 180
Hence , angle R + angle S + angle T = 180
... 3x + 30 + 12x - 15 + 3x + 30 = 180
... 18x + 45 = 180
... 18x = 180 - 45
... 18x = 135
... x = 135 / 18
... x = 7.5
Now substitute the value of x in the angle formula of R and we get the angle R.
... 3x + 30
... 3 ( 7.5 ) + 30
... 22.5 + 30
... 52.5° is the answer
Hope my answer helps!
