Answer:
y =(v-4)^2 -4
Step-by-step explanation:
vertex form of a parabola is
y = a (v-h)^2 +k
where (h,k) is the vertex
y =a(v-4)^2 +(-4)
y =a(v-4)^2 -4
now substitute another point in to determine a
let's pick 0, 12
12 = a((0-4)^2 -4
add 4 to each side
16 = a * (-4)^2
16 = a*16
divide by 16
a = 1
substitute in what we know
y =1 *(v-4)^2 -4
y =(v-4)^2 -4
Answer: moderate positive correlation
Step-by-step explanation: If your correlation coefficient is positive, that means that your slope which is how steep the line is or your line of best fit must also be positive.
Remember that the correlation coefficient is just a number that indicates the direction and closeness of points of a line of best fit.
If it has a correlation coefficient of 0.89, the points would be close together but not very very close.
The first one is $4 per bag, as given
For the he second one, you divide $15 by 4, you got $3,75 per bag
Therefore, the second one has the better unit price
For this case we have the following numeric expression:
40,583
What we should do is write the same number in words.
To do this, we must take into account the correct location of each of the digits.
Then we can write the number correctly.
We have then:
40,583 = Forty thousand five hundred eighty-three
Answer:
The number written in words is:
40,583 = Forty thousand five hundred eighty-three
The answer is B
have a great day
