Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
1) Add all the values.
= 10 + 35 + 30
= 75
2) 75 will be the denominator and the one required will be the numerator.
Since there are 30 peanut butter cookies, the probability is [tex]\frac{30}{75}[/tex].
3) Simplify the fraction if necessary.
Divide both sides by 15.
= [tex]\frac{2}{5}[/tex]

An energy bar company manufactures peanut butter and chocolate bars.
Peanut butter bars cost 25¢ per lb.
The chocolate bars cost 30¢ per lb.
The company sold 260 lbs of bars for $71.
How many of the bars sold were peanut butter?
Answer:
sold 120 chocolate bars
sold 140 peanut butter bars
Step-by-step explanation:
x = peanut butter bars
y = chocolate bars
x + y = 260, total lbs
0.25x + 0.30y = 71, money
solve double variable equation
multiply -4 on both sides for 2nd equation
-x + -1.2y = -284
add both equations together
-0.2y = -24
y = 120
x = 260 - 120
x = 140
sold 120 chocolate bars
sold 140 peanut butter bars
What is the equation of the line that passes through the point (4,−2) and has an undefined slope?
When a line has an undefined slope, it means that it is a vertical line. Vertical lines are written in the following form:
[tex]x=d[/tex], where d is the x-interceptThe x-intercept of a vertical line is the value of x when y=0Solving the QuestionFor any vertical line, the x-coordinate is constant. This means that for any point that falls on the line, the x-coordinate will always be the same.
If we're given that the line passes through the point (4,-2), this means that the x-coordinate for every piont this line passes through is 4.
In other words, the x-intercept of this line is 4.

In y = 2^x + 1, what is the exponent?
Step-by-step explanation:
The natural log has a base of 'e'. That is the definition of the natural log. Therefore, using logarithm rules, 'e' to the power of the right side equals 'y':
[tex] {e}^{ {2}^{x} + 1 } = y[/tex]
Answer:
xStep-by-step explanation:
In this problem, x is the exponent as the term '2' is multiplied by itself x times. If you look a bit further, you will see there is also an invisible power on 1, but 1 raised to any exponent will be 1 itself so it isn't considered.
Two angles of a quadrilateral measure 60° and 160°. The other two angles are in a ratio of 3:11. What are the measures of those two angles?
Answer:
30 and 110 degrees
Step-by-step explanation:
The angles sum to 360 degrees
you have 60 + 160 = 220 leaving 140 more in a ratio 3:11
one is 3 / (3+11) = 3/14 3/14 * 140 = 30 the other is 110
Weekly wages at a certain factory are
normally distributed with a mean of
of
$400 and a standard deviation of $50.
Find the probability that a worker
selected at random makesbetween
$400 and $450.
[? ]%
Answer:
The probability that a worker makes between $400 and $450 is .3413 using the calculator and .34 using the empirical rule.
Step-by-step explanation:
There are two ways to approach this problem.
The first way is to find the z-score corresponding to $400 and $450 weekly wage and find the p-value in between these values.
[tex]\displaystyle \frac{400-400}{50} < z < \frac{450-400}{50}[/tex][tex]\displaystyle 0 < z < 1[/tex]
If you use the normalcdf function on your calculator and put 0 and 1 as the lower and upper bounds, respectively, you will get an area of .3413.
Another way of looking at this problem is to recognize that the weekly wages given are the mean and one standard deviation above the mean.
We can use the Empirical Rule, 68-95-99.7, in order to see that going one standard deviation above the mean would be an area of 68/2 = .34.
I've attached an image that shows you what the normal curve looks like.

Find all values of k for which the equation 3x2−4x+k=0 has no solutions.
This should be an inequality.
Answer:
k>4/3
Step-by-step explanation:
The given quadratic equation is:
3x^2 - 4x + k = 0
To find, the value of k = ?
you use
Discriminant, D = - 4ac
= - 4(3)(k)
= 16 - 12k
The condition of no solutions.
D < 0
16 - 12k < 0
16<12k
4/3<k
⇒ k>4/3

The area of a square is defined by, A(X) = x2 - 6x + 9. What is the length of a side of the square?
1- I-3
2- I +3
3- 2-9
3- x - 6
Answer:
Step-by-step explanation:
None of the answers look right to me unless you are given something I'm not aware of.
A(x) can be factored. When it is, the following is what is obtained.
A(x) = (x- 3)(x - 3)
Since the area of a square is
Area = s^2
where s is the length of the side, you can find the square root by using the rules of roots.
s^2 = (x - 3)(x - 3)
√s²= √(x - 3)²
√s² = s
√(x - 3)² = x - 3
Therefore the answer should be s = x-3
The only thing I think you can do is ask whoever is presenting the course how any of those answers are obtained.
Answer:
x-3

What is the volume of this cone? Use 3.14 for pi and round your answer to the
nearest tenth.
In your answer, give the volume of the cone rounded to the nearest tenth, and then
explain how you calculated it.
Answer:
I had two other people with the same question, so I'm gonna assume that the radius is 2 and the height is 8. Here is the answer: 39.5 in^3
Step-by-step explanation:
The formula for a cone is (pi)(r^2)(h/3)
Since we have to use 3.14 for pi, we plug 3.14 in for pi:
(3.14)(r^2)(h/3)
The radius is 2 and the height is 8, so we plug in those numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.666...)
Multiply:
(12.56)(2.666...) -> 39.49333...
Finally, we round 39.49333... to the tenths place:
39.5

what is the surface area of this cylinder ?
Answer:
87.92 mm²
Step-by-step explanation:
Given:
Radius of circular base: 2 millimetersHeight of cylinder: 5 millimetersIt should be noted:
Surface area of cylinder: 2πrh + 2πr² (R = Radius; H = Height)When the measures are substituted, we get the following expression:
⇒ 2π(2)(5) + 2π(2)²Multiply the constants and substitute π as 3.14.
⇒ 20π + 2π(4)⇒ 20π + 8π⇒ 20(3.14) + 8(3.14)Finally, simplify the expression to determine the surface area.
⇒ 20(3.14) + 8(3.14)⇒ 62.8 + 25.12⇒ 87.92 mm²Answer:
88.0 mm² (nearest tenth)
Step-by-step explanation:

which form most quickly reveals the vertex?
And what is the vertex??
Answer: Choice C
Vertex = (5, -2)
===============================================
Explanation:
Vertex form is [tex]y = a(x-h)^2 + k[/tex] where the vertex itself is located at (h,k)
As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.
In the case of choice C, we have [tex]y= \frac{1}{2}(x-5)^2 - 2[/tex] which is the same as [tex]y = \frac{1}{2}(x-5)^2 + (-2)[/tex] and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)
