What is the vaule of x for this problem 2x plus 52 equals to zero?
2x+52=0 =>2x= -52 =>x= -52/2 =>x= -26
What is the answer to 52 tens?
52 tens = 52 x 10 = 520
What is your score if you miss 12 out of 25?
The most that you can get is 52% but that assumes you did not get any answers wrong. Is that realistic?
What is Z-score for x equals 52 when a normal distribution has a mean of 50 and a standard deviation of 20?
You need to ask 1 question at a time, rewording it into 200 characters or less - it helps you to actually think about what is required instead of getting others to do your work for you. z = (x - µ)/standard deviation = (52 - 50)/20 = 0.1 (If z is negative it is below the mean.)
How do you multiply by 20?
* Multiply by 10 (by addind a zero to the right of the number), * then double: Example - multiply 52 by 20: 52 x 10 = 520 double 520 = 1040
