these two bars | | mean <u>absolute value</u>
here's how to find x
| x - 7| = 2
first apply the absolute rule
x - 7 = 2 x - 7 = -2
in both equations add 7 on both sides
x - 7 + 7 = 2 + 7 x - 7 + 7 = -2 + 7
then simplify the expressions
x = 9 x = 5
now combine these two solutions to get your answer
x = 9 or x = 5
hopefully my explanation helps
Answer:
Let x represents the hours and y represents the total fees(in dollars)
As per the statement:
(a)
For a house call, a veterinarian charges $70, plus $40 an hour
"$40 an hour" means 40x
then;
the equation we get;
.....[1]
(b).
Find the x-intercept.
x-intercept states that the graph cross the x-axis.
Substitute y = 0 in the equation and solve for x;
we get;
y-intercept states that the graph crosses the y-axis i.e
Substitute x= 0 in the equation and solve for y;
Therefore, x-intercept and y-intercept of equation [1] are:
and 70
The answer is 19. Hopefully this helps
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.
