The mode of a data set is the entry that occurs the most often. Since 92 is the most frequent number in the set, that is the mode.
To determine the number of cups that should be poured form the liter of orange juice, we convert first 1 liter to cups. In every liter there are 4.23 cups. So, we can pour out 4 cups. Approximately 0.23 cup of the juice will be left.
The form of an eclipse is written as:
(x-h)^2/b^2 + (y-k)^2/a^2 = 1
Matching the values in the given equation tot he form of an eclipse you have:
a = 6
b = 4
k = 0
h = 0
A is the radius of the major axis and b is the radius of the minor axis.
H is the X offset and K is the Y offset.
The first vertex is written as (h, k+a)
Replacing the letters with their values you get:
(0, 0+6) = (0,6)
The second vertex is written as (h, k-a)
Replacing the letters with their values you get:
(0, 0-6) = (0,-6)
The vertices of the are (0,6) and (0,-6)
The vertices are the end points of the major axis, since 6 and -6 are longer than the minor axis of -4, 4 the ellipse has a vertical major axis
Answer:
c.Observational study. The variable of interest is the result of either correct or incorrect to each trial.
Step-by-step explanation:
Observational study is the type of study when a researcher don't influence the outcome of an experiment by imposing a treatment and only observe the outcome of an experiment. A nine year old tested professional observes therapists choices and so this is the observational study.
A nine year old tested professional observes therapists choices and the choice of therapist can be correct or incorrect. So, the variable of interest is the result of either correct or incorrect to each trial.
