First you have to make the assumption that these are the only two outcomes. There is also the possibility of hitting the ball and getting out.
However, if we assume that these are the only two cases, we know that the probability is 58.3%. This is because it has been on base 7 times out of 12.
Answer:
False.
Step-by-step explanation:
√x = -7 ... Square both sides
x = 49
This question is kind of tricky, and there's a few ways to look at it, but I think that's the most understandable. Another thing you can notice is that if x = -49, you can't take the square root of a negative value (unless you're including complex values with the imaginary "i"), or that the square root of a value is -7, the original value would have been (-7)*(-7) which gives you a POSITIVE 49, not a negative one.
Answer:
454
Step-by-step explanation:
set up a system of equation
let y be the number of students
let x be the number of adults
because there are twice the amount of students attended as adults, we can use y=2x as one equation
the other equation will be 6.5y+9x=4972 because this represents the total amount of money
plug 2x for y : 6.5(2x)+9x=4972 : x=226
plug 226 in for the first equation : y=2(226) : y=452
Do the following,
(18x2)x2=?
(18x9)x2=?
(9x2)x2=?
Then add them all up!
