Answer:
Step-by-step explanation:
We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population
That means total number of students being surveyed is 13+13=26 students
Then we work out the probability
P(One pet) = 8/26 = 4/13
P(Two pets) = 1/2
P(Three pets) = 3/26
P( Four pets) = 2/26 = 1/13
The probability distribution is shown in the table below. Let be the number of pets and is the probability of owning the number of pets
Answer:
The rectangle will have side lengths of 2,2,4,4.
Step-by-step explanation:
This combination gives a perimeter of 12 units, and an area of 8 units. I couldn't really draw it out but I hope this helps :)
Proportional is
if you have
y=number of pits
x=profit
then
y1/x1=y2/x2
y1 and x1 are first number of pits and profit
y2 and x2 and second number of pits and profit
so
given
3 pits and 80 then
5 pits and 200
12 pits and 620
3/80=5/200=12/620
true?
3/80=1/40=3/155
use caltulator
0.0375=0.025=0.019
these are obiously not equal
so the answer is no, so either c or d
hmm
c means that the slope (or the values we calculated) wer less than original
0.0375>0.025>0.019
true
d. this is also true since they are not proportional
not sure, it is either c or d, I would go with d
Answer:
Option A
Step-by-step explanation:
The set of values for which y is a function of x is the set where each x-value has exactly on y-value. No x-value has more than 1 y-value.
✅Option A: y is A FUNCTION of x because it has exactly one y-value assigned to each x-value.
❌Option B: y is NOT a function of x because there are two y-values, 4 and 2, that are assigned to one x-value, -1.
❌Option C: y is NOT a function of x because there are two y-values, 10 and 12, that are assigned to one x-value, 1.
❌Option D: y is NOT a function of x because there are two y-values, 2 and 4, that are assigned to one x-value, -1.
