6 fish. since 3 is half of the total, 3x2=6
First of all, as I told you a little while ago, here is the formula
that solves ALL probability problems. Memorize this:
Probability =
(number of different successful possibilities)
divided by
(total number of all possibilities).
There are 10 keys in the bag. The total number of possible results
of pulling out one key out is 10.
3 of the keys start the car. The other 7 keys don't.
What are the 'successful' possibilities ?
The question asks for the probability of pulling keys that DON'T work.
So for this particular calculation, we're talking about choosing keys
that DON'T work. There are 7 of those.
The probability of drawing a key that doesn't work the first time is 7/10 .
Since the first key is put back in the bag and the bag is mixed, the
situation on the second draw is exactly the same as on the first one.
Thje probability of drawing a key that doesn't work the second time is 7/10 .
The probability of both events happening is (7/10)x(7/10) = 49/100 = 49% .
when multiplying scientific notation all you' do is move the decimal whatever times the exponent says or the little number on the 10. Move it to the right when its positive and when its negative move it to the left . I hope that helped :)
Answer:
She needs to score 82
Step-by-step explanation:
Mean of five test scores = 82
Let the score she got in fifth test = x
Answer:
y intercept = 4
x intercept = -8
Step-by-step explanation:
0 = x/2 + 4
-4 = x/2
-8 = x
y=mx+b
y = 1/2x+4
Y intercept = b, b= 4
