Answer: 9/25
Step-by-step explanation:
Since 3 of them have neither a cat or a dog, that means 22 (25-3) of them have a dog, a cat, or both.
16 + 15 = 31, which is 9 more than 22. That means 9 of them have both a dog and a cat.
Out of the 25 people, 9 have both a cat and dog, which means the probablity a student chosen at random has both is 9/25.
It is 0.17. hope it helps
Answer:
72°
Step-by-step explanation:
The lengths 25 cm and 8 cm are the sides of the rectangle.
See the attached diagram of rectangle ABCD.
Now, let us assume the diagonal AC makes x° angle with the shorter side BC i.e.∠ BCA = x°
So, using trigonometry we can write

⇒
degrees ≈ 72 degrees {Rounded to nearest degree} (Answer)
Answer:
9
Step-by-step explanation:
Solution
Here,
(a^3)^6=(a^2)^x
or, a^18=a^2x
or, 18=2x
or, x=18/2
x=9
Primes are
2,3,5,7,11,13...
ok, so it must be multiplule of 2,7 and 11
2*7*11=154
answer is 154
