How do you solve x + 5 = 12? | Socratic
Jun 7, 2018 · Right now, only 5 is being added to it, so to solve for it, we need to do the inverse operation, subtraction. Remember, we subtract 5 from both sides to maintain the equality. We get. x = 7. We can even plug in 7 for x to make sure our answer is reasonable: 7 + 5 = 12. ⇒ 12 = 12. This is true, so x = 7 is our solution. Hope this helps!
Assume that a procedure yields a binomial distribution with a trial ...
May 7, 2018 · Probability of 5 successes among 12 trials is 0.10324 Binomial distribution gives the probability of x successes among n trials as C_x^np^xq^((n-x)), where p is probability of success in one trial and q is probability of failure i.e. q=1-p In the given case, we have n=12, x=5 and p=0.25 i.e. q=1-0.25=0.75 Hence probability of 5 successes among 12 trials is …
If tan (x) =5/12, then what is sin x and cos x? - Socratic
Apr 15, 2015 · Viewed as a right angled triangle #tan (x)=5/12# can be thought of as the ratio of opposite to adjacent sides in a triangle with sides #5, 12# and #13# (where #13# is derived from the Pythagorean Theorem) So #sin (x) = 5/13# and #cos (x) = 12/13#. Answer link. Shreya Naik. Sep 1, 2015. This can be solved easily once we visualise it.
How do you solve 5/8 = x/12? - Socratic
Mar 4, 2016 · Explanation: 5 8 = x 12. To get x by itself, you must multiply each side by 12 (to cancel out the 12). 12 ⋅ (5 8) = (x 12) ⋅ 12. Simplify each side. 60 8 = x. Simplify final answer. 15 2 = x. Answer link.
How do you solve #12^(x) - 5 > 6 ^(1-x)#? - Socratic
Aug 20, 2015 · x>0.756214 this is a numerical approximation to the solution and only accurate to 6 s.f.. Move all expressions to one side of the inequality: f(x)=12^x-5-6^(1-x)>0 Taking the derivative of the left side with respect to x we have: f'(x)=log(12)12^x+log(6)6^(1-x) This expression is positive for all x in RR, therefore f(x) is strictly increasing at all times. This leaves …
Equations of Perpendicular Lines - Algebra - Socratic
Any line that is perpendicular to it must be opposite (negative instead of positive or vice versa) reciprocals (multiplicative inverse, reciprocals multiply to 1, flip the numerator and denominator) Opposite of 3: -3. Reciprocal of -3 (#-3/1#): #-1/3#. Lines that are perpendicular to #y=3x# must have a slope of #-1/3#.
How do you determine the probability distribution of #P(x>5)
Mar 6, 2017 · Explanation: The standard notation is to use a lower case letter to represent an actual event, and an upper case letter for the Random Variable used to measure the probability of the event occurring. Thus the correct table would be: And then; P (X> 5) = P (X = 6 or X = 7 or X = 8) = P (X = 6) +P (X = 7) + P (X = 8) = 0.2 +0.1 +0.5. = 0.8.
How do you combine #(x+2)/(x-5)+(x-12)/(x-5)#? - Socratic
Mar 16, 2017 · Before we can add/subtract fractions we require them to have a common denominator. These fractions have a common denominator ( x - 5) so we can add the numerators, leaving the denominator as it is. ⇒ x + 2 + x − 12 x − 5. = 2x − 10 x − 5. The numerator can be simplified by taking out a common factor. ⇒ 2x − 10 x − 5 = 2(x −5)1 ...
