Answer: It will be a positive parabola with it's point at (-3,4)

Step-by-step explanation:

The graph is parabola since x is squared. Anything inside of parentheses with the x will deal with the x axis, with the x axis you have to reverse the sign of the number (positive to negative and negative to positive). Therefore, you go left by 3. Since the 4 is outside of the parentheses, it has to do with the y axis. Wit the y axis you do not have to reverse the sign, so you go up 4.

The probability that a newborn baby at the hospital is female is 50%. What is the probability that at least 2 babies of 3 childr

Answer:

0.25 is the probability

Step-by-step explanation:

In this question, we are tasked with calculating the probability that in a hospital on a certain day, at least 2 out of three babies born that day are female.

To calculate the probability , let’s list out some needed facts;

Let the probability of having a baby girl be g = 50% = 50/100 = 1/2 = 0.5

The probability of having a boy b will be 1-g = 1-0.5 = 0.5

Now, we have 3 babies and we want to find the probability of at lest two being girl.

Mathematically that would be ; ggb or ggg

since we are having at lest 2 girls

For the ggb, we have ; 0.5 * 0.5 * 0.5 = 0.125

For the ggg we have 0.5 * 0.5 * 0.5 = 0.125

In probability, once we have or, we add.

Thus 0.125 + 0.125 = 0.25

Plz help I’m need help

I can’t really help you too much with the graphing but what you do with ordered pairs is whatever is the first number (example for point A it’s -2) you go and find it on the horizontal line. Once you find it on the horizontal line you either go up or down the graph by how many units the second number is (4 so you would go up four in the graph) and then you plot the point

Which is the equation of a line that passes through the point (3,2) and is parallel to the y-axis

algol13

If it's // to y-axis that means it never intersects with y-axis . Since it passes through (3,2) means that x=3. This is the answer x=3

hat is the average rate of change of f(x), represented by the table of values, over the interval [-2, 3]? x f(x) -6 2.5 -2 2.5 0

vodomira [7]

Your table of values is so difficult to read that many of us helpers would just skip your post.

<span>x f(x) -6 2.5 -2 2.5 0 2 2 0 3 5 5 2.5 1 0.5</span> could be put into far clearer format as follows:

x f(x)
-- -----
-6 2.5
-2 2.5
and so on. Please fix it.

The "average rate of change" formula is

f(x2) - f(x1)
av r of c = ---------------
x2-x1

so if you go from (-6, 2.5) to (2.5, 10.5), the av r of c would be

10.5 - 2.5 9 18
------------------ = -------- = -----
2.5-(-6) 8.5 17

This may or may not be your final answer. Again, please put your data table into readable form and then find the av r of c over the interval [-2,3].
