Answer:
21 is 20% of 105
Step-by-step explanation:
20% * x = 21
20/100 * x = 21
x = 21 * 100/20
x = 105
If you are using a calculator, simply enter 21×100÷20, which will give you the answer.
Answer:
7 / 16
Step-by-step explanation:
Sample space is attached below :
Theoretical Probability of any event A
P(A) = (number of required outcome / Total number of possible outcomes)
Required outcome = sum greater than 7 = 14
Total number of possible outcomes = 32
P(sum greater than 7) = 14 / 32
P(sum greater than 7) = 7 / 16
The answer is k-20
decreased means to take away/subtract, “k” is being subtracted by 20, therefore k-20
Hope this helps! have a wonderful day!
