Answer:
Step-by-step explanation:
What is the smallest value of the number?
minimum
The minimum is the smallest value in the data set. The maximum is the largest value in the data set
The product of a number and negative seven is at most negative eighty-four?
8(-4x). X is the number?
Answer:
28.57% probability that the oldest is a girl and the youngest is a boy, given that there is at least one boy and at least one girl.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
These are all the possible outcomes: from youngest to oldest, b is boy and g is girl
b - b - b - g
b - b - g - b
b - b - g - g
b - g - b - b
b - g - b - g
b - g - g - b
b - g - g - g
g - b - b - b
g - b - b - g
g - b - g - b
g - b - g - g
g - g - b - b
g - g - b - g
g - g - g - b
The nuber of total outcomes is 14.
Desired outcomes:
Oldest(last) girl, youngest(first) boy
b - b - b - g
b - b - g - g
b - g - b - g
b - g - g - g
So 4 desired outcomes
Probability:
4/14 = 0.2857
28.57% probability that the oldest is a girl and the youngest is a boy, given that there is at least one boy and at least one girl.
That seems as if it is something that should be entered into a spreadsheet such as Excel or Open Office.
The equation is there so you can find the rate of change and the y-intercept which is done like so:
rearange the variables and numbers by moving the x it the right side of the = which becomes -x.
2y= -x-4
divide the 2 by the -x and -4
which gives us:
y= -1/2x -2
so the rate of change is -1/2 and the y-intercept is -2.
we use the points to plug it into an equation that looks like this:
y-y1 = m(x-x1)
plug in the numbers like so:
y-5= -1/2(x+8)
distribute first:
y-5= -(1/2)x - 4
then get the y alone by adding 5 to -4, which leaves us with
y = -(1/2)x+1
the answer is:
Y= -(1/2)X +1
