X must be increased by 6 to get its value to be 0. Then the corresponding change in y will be (-2/3)*6 = -4. That value added to -5 makes it -9.
The y-intercept will be -9.
This can be solved by using the normal approximation to the binomial distribution.
mean = np = 10.000 * 0.5 = 5,000
The standard deviation is given by:
The probability of obtaining more than 5100 tails is 0.0228 and the probability of obtaining fewer than 5100 tails is 0.9772.
The odds of obtaining more than 5100 tails is therefore:
0.0228:0.9772 = 1:42.86.
In guessing the expression is
12-8x7
So the answer is 28
first what you have to do you have to find the common denominator which is 24
it's 24 because 8 times 3 equals 24 and 12 times 2 equals 24 so they have a like denominator so what you have to do to the bottom you have to do to the top so 8 times 3 is 24 so 3 times 3 is 9 so the new fraction is 9/24. Then 1/12 12×2=24 and 1×2= 2 so the new fraction is 2/24. that would leave you with the problem of 9/24 + 2/24 which is 11/ 24
the math behind it:
your equation looks like this: .25x = 10
then you divide both sides by .25 and then ur equation looks like this: x=40
by the way the variable x stands for the number you are looking for. and since x=40, the number you are looking for is 40
well i hope i helped!
