The phrase “the difference between a number and 5” as a variable expression would look like: x - 5
Answer:
68
Step-by-step explanation:
Add all of the numbers together then divide by the amount of numbers there are.
Answer:
½ = x
Step-by-step explanation:
As discussed in one of my You-Tube videos on Exponential Rules, aᵐ\ⁿ, any base to the half power is the SAME AS taking the exponential denominator of that power, and setting that to the square root of the base, leaving the exponential numerator on the outside:
25¹\² = √25
25 = a [Base]
1 = m [Exponential Numerator]
2 = n [Exponential Denominator]
As you can see, it is unnecessary to put the two because by definition, any vacant root is automatically assumed as the square root, and 1, which is the exponential numerator, is on the outside, which again is unnecessary because 5¹ is 5.

m<QRS = 80 degrees.
Supplementary angles = a total of 180 degrees. So if angle ABC = 100, angle QRS would = 80 degrees.

Answer:
C. No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
Step-by-step explanation:
Given that an experimental drug is administered to 90 randomly selected individuals, with the number of individuals responding favorably recorded.
We find here the no of trials are 90 but we cannot say the probability is the same for all trials.
In other words, each individual may have a different probability to respond.
Since p , the success for each trial may differ for each trial binomial cannot be accepted
C. No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
