Pecan producers blow air through the pecans so that the lighter ones are blown out. The
lighter-weight pecans are generally bad ("bad nuts") and the heavier ones tend to be better
D("good nuts"). These "blow outs" and "non-blow outs" are often sold to tourists along the
highway. Suppose that 50% of the pecan "blow outs" are good and 80% of the "non-blow outs"
are good.
a. If you purchase 30 pecans, what is the expected number of good nuts you will find if you
purchase "blow outs?"

Sara was asked by Mr. Rocha to solve the equation below. − 3 x = y + 51 What is the value of x when y has a value of − 9 ?
Answer:
x = - 14
Step-by-step explanation:
Given equation
-3x = y + 51Putting the value of y
-3x = -9+51-3x = 42x = - 42/3x = - 14Hope it's helpful!

The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14.
What is the equation?An equation is said to be linear if the maximum power of the variable is consistently unity.
More than one variable may be present inside a linear equation.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
-3x = y + 51
At y = -9
-3x = -9 + 51
-3x = 42
x = -14
Hence "The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14".

What is the equation of this line in standard form?
A: 9x−8y=23
B: 8x−9y=23
C: 8x−9y=−23
D: 8x−7y=−25
Answer:
B:8x-9y=23
Step-by-step explanation:
First find the slope:
m= y2-y1/x2-x1
y2 is 3
y1 is -1
x2 is 1/2
x1 is -4
3-(-1) is 4
1/2-(-4) is 9/2
Now the equation looks likes this:
4 / 9/2
Which can be rewritten as
4*2/9
Thus the slope is 8/9
So the equation is
y=8/9x+b
Now you can substitute to find the y-intercept:
(you can do either (-4,1) or (1/2,3)
I am going to do (1/2,3) since it is easier
3=8/9(1/2)+b
Simplify:
3=4/9+b
Subtract 4/9 on both sides:
b=23/9
Thus the equation is
y=8/9x+23/9
Multiply 9 on both sides:
9y=8x+23
Subtract 8x on both sides:
8x-9y=23
Hope this helps!
Solve the equation for x.
x/5 = -8
Answer:
x = -40
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Multiply 5 to both sides of the equation:
(x/5) * 5 = (-8) * 5
x = -8 * 5
x = -40
x = -40 is your answer.

The area for any square is given by the function f(x)=x2, where x is the length of a side of the square. Find and interpret f(3.5).
f(3.5)= ______ which means the area of a square with a side of length _______ units is _____ square units
Answer:
see explanation
Step-by-step explanation:
f(x) = x² , then
f(3.5) = 3.5² = 12.25
which means the area of a square with a side of length 3.5 units is 12.25 units²
The area of a square with a side of length 3.5 units is 12.25 square units.
What is an area?Area is the quantity that expresses the extent of a region on the plane or on a curved surface.
Given that, the area for any square is given by the function f(x) = x², where x is the length of a side of the square
f(x) = x²
f(3.5) = 3.5²
f(3.5) = 12.25
Hence, The area of a square with a side of length 3.5 units is 12.25 square units.

Which of the following linear equations is perpendicular to the line 3x-2y=8 and passes through the point (-3,2)?
A) y= -2/3x
B) y= -2/3x+4
C) y= 3/2x+13/2
D) y= 2/3x+4
E) y= 2/3x
Answer:
3 x - 2 y = 8
y = 3/2 x - 4 rearranging
y = m x + b standard equation for line
m' = - 2/3 for perpendicular line m m' = -1
y = - 2/3 x + b
b = y + 2/3 x = 2 + 2/3 * -3 = 0 substituting given values
y = 2/3 x required line

The Pie Problem!
Question: The Morgans had pumpkin pie for their Thanksgiving dessert.
The mom ate 1/4 of the pie. The dad ate 2/3 of what was remaining after the mom ate
her portion. The daughter ate 1/2 of what was remaining after the dad ate his portion
How much of the ple is left after the daughter ate her portion?
Answer:
1/12
Step-by-step explanation:
find the least common multiple of the denominators.
which is 12
so 1/4=3/12
2/3=8/12
1/2=6/12
so 3/12- 8/12 - 6/12 = -11/12
so there is 1/12th pieces left after they all ate their portions of the pie

the sum of two numbers is 75. the first is 9 more than 5 times the second. find the first number
Answer:
1st number is 64
Step-by-step explanation:
Lets start by making the words into equations.
So the 1st plus the 2nd is 75:
1st+ 2nd= 75
Now the tricky part. The 1st is 9 more than 5 times the 2nd. The key word 'times' means multiplication, we we will have 5 x 2nd somewhere in our equation. The '1st is 9 more than' part tricks us into thinking we will have 1st plus 9, BUT WE WON'T because it isn't 9 more, its 9 more THAN. This means we will get.
1st= 5 x 2nd +9
To make this a little cleaner, I will have the 1st = X and the 2nd= y.
x+y=75
x=5y+9
We can substitute the bottom equation into the top equation.
5y+9+y=75
Combine like terms
6y+9=75
Solve for Y by getting y alone.
6y+9=75
6y=66
y=11
Then we can take our value of y and plug it back into either equation to solve for X. The top equation is the easiest.
x+11=75
Isolate x to solve for x
x=64
And we established that x= the 1st number, so the 1st number is 64

Solve for the variable cin this equation:

A. C= d-ab/a
B. C= d+ab/a
C. C= ab- d/a
D. d-ab/b
Answer:
A. C = (d-ab)/a
Step-by-step explanation:
a(c + b) = d
a(c + b)/a = d/a
c + b = (d/a)
c = (d/a) - b
a(c + b) = d
ac + ab = d
ac = d - ab
ac/a = d/a - ab/a
c = (d/a) - b
