Answer:
A ; 1/4
Step-by-step explanation:
In a standard normal cube , we have the numbers labeled 1 to 6
the prime numbers we have here are 2 , 3 and 5
The probability of selecting a prime number is thus 3/6 = 1/2
Now this means the probability of rolling a prime number here is 1/2
Now we calculate the probability of spinning a prime number
Prime numbers here are just 2 and 3
The probability of spinning a prime number is thus 2/4 = 1/2
Thus, the probability of rolling a prime number and spinning a prime number also becomes; 1/2 * 1/2 = 1/4
As the 2 quadrilaterals are congruent the sides of one quadrilateral are equal to the corresponding sides of the other quadrilateral
Hence,
AB = PQ
RQ = BC
AD = PS
DC = RS
Since terms for both AB and PQ are given we can equate the terms and find m
5m -9 = m + 11
5m -m = 11 + 9
4m = 20
m = 5
Correct answer is D , 5
Step-by-step explanation:
= 1,9 × 10^-6
= 1,9 × 0,000001
= 0,0000019
The answer is 2. You can find it by multiplying 20 and 21 giving you 420 and since 420 is half of 840 then all you would have to do is multiply 420 by 2 meaning the height is 2 since if you multiplied all in one it would be 20 x 21 x 2=840
