Answer:
Step-by-step explanation:
Given:
Number of people to be seated should be greater than 75.
Let be the number of people. So,
Now, there is a single private chef's table that can seat 3 people.
Tables bought by the owner =
Number of people seated in 1 table = 4
So, number of persons that can be seated in tables =
Now, total number of persons that can be seated in these two types of tables is the sum of 3 and
Therefore,
But,
Hence, the inequality to show the situation is:
The equation of parabola is
Comparing with the vertex form of the parabola:
Hence, the vertex of the parabola is given by (h,k) = (1, -2)
Now, vertex is the midpoint of the focus and the point on the directrix.
Distance, between vertex and focus is p and that of point on the directrix is p.
Now, let us find p
Thus, the focus is given by
And the directrix is given by
Since, a >0 hence, it is an upward parabola.
The graph is shown in the attached file.
His model is incorrect because 20 x 7 is not 14, it is 140. If he had 140 instead of 14, he would have been correct.
I haven't done division like that in a long time, so this is what I think it will look like. I didn't add other work (multiplying 4 with #'s) but you can if you have to
Answer:
Step-by-step explanation:
Given that x = no of movies high school students watched is N(6.8, 1.8)
Sample size = 36 and hence std error = 1.8/6 = 0.3
(two tailed test)
Mean difference = 6.2-6.8 = -0.6
Test statistic z = -0.6/0.3= -2
p value = 0.02275
Since p <0.05 we reject H0.
There is evidence to show that college students watch fewer movies a month than high school students
