Answer:
Probability = 37.5%
Step-by-step explanation:
Prob (Race fast) = 10%, Prob (Slight Fast) = 40%, Prob (Normal Car) = 50%
Prob (Red Car) = 70% of race fast cars, & 45% of slight fast cars, & 30% of Normal cars, & = (70% x 10%) + (45% x 40%) + (30% x 50%) = 7% + 18% + 15% = 40%
Prob (Normal & Red Car) = 30% of 50% = 15%
Prob (Red car I Normal car) = Prob (Red & Normal Car I Normal Car) = 15% / 40% = 37.5%
Answer:
Step-by-step explanation:
<span>So we want to know what is the area of the shaded reagion that consists of a circle inside a square If the side of the square is a=10cm. For that we simply calculate both areas and subtract the area of a circle from the area of a square: area of a square A=10^2=100 cm^2, area of a circle B=pi*r^2 where r=a/2. So: B=3.14*5^2=78.5cm^2: A-B=100-78.5=21.5cm^2 So the correct answer is D</span>
Answer:
∠A is acute. ∠A is acute.
Step-by-step explanation:
Given that
m∠A is lower than 90°
So, it is an acute angle
And, M∠A=75°
The acute angle is the angle that measures between 0 degrees and 90 degrees on the other case the obtuse angle should be more than 90 degrees till 180 degrees
So as per the law of detachment the first option is correct and the same is to be considered
