The number of songs enjoyed from Eminem by all Learn4Life students is normally distributed with a mean of
7.0 songs and a standard deviation of 1.5 songs.
1. What is the probability an individual student likes more than 10 songs from Eminem?
2. What is the probability an individual student likes less than 5.5 songs from Eminem?
Answer:
P(X > 10) = 0.0228
P(X< 5.5) = 0.1587
Step-by-step explanation:
Given that:
Mean = 7.0
standard deviation = 1.5
To find:
a) P(X>10)
Using the standard normal variation
[tex]Z = \dfrac{x -\mu}{\sigma}[/tex]
[tex]Z = \dfrac{10 -7.0}{1.5}[/tex]
Z =2.0
So;
P(X > 10) = P(Z > 2.0)
P(X > 10) = 1 - P(Z < 2.0)
From the tables
P(X > 10) = 1 - 0.9772
P(X > 10) = 0.0228
b) To find:
P(X < 5.5)
[tex]Z = \dfrac{x -\mu}{\sigma}[/tex]
[tex]Z = \dfrac{5.5 - 7.0}{1.5}[/tex]
Z = -1.0
However;
P(X< 5.5) = P(Z < -1.0)
P(X< 5.5) = 0.1587

Lucy has a goal of walking at least 15 miles she walks at a rate of 5 miles per hour which inequality can Lucy used to find H the number of hours she should walk in order to meet or exceed her goal
Answer:
5h>15
Step-by-step explanation:
✓From the question, we were informed that Lucy walks at a rate of 5 miles per hour, this implies that 5 is multiplied by amount of hours (5×1h)= 5h
✓ we need to find the inequality that Lucy can use to find H the number of hours she should walk in order to meet or exceed her goal, To find this as equation, we know that Lucy must walk for at least 15 miles which implies that the (5h) will always be greater than 15 miles. We can put it in equation as
5h>15
NOTE: Inequality provide the relation that exist between two unequal expression. Using notation such as

Which function has an inverse that is also a function?
O {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)}
O {(-4, 6), (-2, 2), (-1, 6), (4, 2), (11, 2)}
O {(-4, 5), (-2, 9), (-1, 8), (4, 8), (11, 4)}
O {(-4, 4), (-2, -1), (-1,0), (4, 1), (11, 1)}
In {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)} function has an inverse that is also a function. Therefore, option A is the correct answer.
What is inverse function?Inverse function is represented by f⁻¹ with regards to the original function and the domain of the original function becomes the range of inverse function and the range of the given function becomes the domain of the inverse function. The graph of the inverse function is obtained by swapping (x, y) with (y, x) with reference to the line y = x.
We know that a function is only a function such that there is a unique value of y corresponding to x.
An inverse function will only be a function if the function which is going to be inverse is a function.
In {(-4, 3), (-2, 7), (-1,0), (4, -3), (11, -7)} all value of x corresponding to y are different but in all remaining options the values are repeating hence that will be not a function since only option A has to inverse.
Therefore, option A is the correct answer.

If the sphere shown above has a radius of 6 units, then what is the approximate volume of the sphere? (Use 3.14 for .)
Answer:
The approximate volume of the sphere is 904.32 cubit units
Step-by-step explanation:
The volume of a sphere
Given a sphere of radius r, its volume is calculated by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
The radius of the sphere is r=6 units, thus the volume of the sphere is:
[tex]\displaystyle V=\frac{4}{3}\pi 6^3[/tex]
π≈3.14
[tex]\displaystyle V=\frac{4}{3}\cdot 3.14\cdot 6^3[/tex]
[tex]\displaystyle V=\frac{4}{3}\cdot 3.14\cdot 216[/tex]
V = 904.32 cubit units
The approximate volume of the sphere is 904.32 cubit units

A ball is pushed down a hill with an initial velocity of 2.5 m/s. As it rolls it accelerates at a rate of 6m/s/s. What will be it’s velocity 1.5 minutes later?
Answer:
Step-by-step explanation:
This is more physics than math because you need to know the equations for one-dimensional motion to get this done. The equation we need is
[tex]v=v_0+at[/tex] where v is the final velocity, v0 is the initial velocity, a is the acceleration and t is the time in seconds. That means that since our time is given in minutes we have to convert it to seconds. I'm not sure how much importance your teacher gives to significant digits, but if you use them here, the answer you get is way off, so we will disregard them here. 1.5 minutes is 90 seconds. Now that have the time in seconds and the equation we need, we will fill it in accordingly:
[tex]v=2.5\frac{m}{sec} +(6\frac{m}{sec^2})(90sec)[/tex]
Note immediately that the seconds on the time cancels out one of the seconds in the denominator of the acceleration so we're left with m/sec + m/sec which is what we need to add those 2 terms. Multiply 6 by 90 to get 540 m/sec. then add that to 2.5 m/sec to get 542.5 m/sec. That must be really long hill!!!

The football team at the local high school was doing a fundraiser to raise money for a tournament. They sold chocolate chip and oatmeal raisin cookies. The amount of oatmeal raisin cookies they sold was 10 less than 4 times the amount of chocolate chip cookies. If they sold 525 cookies how many of each type did they sell? Please answer and show work!!!!!!!!!!!!
Answer:
412 Oatmeal Raisin and 103 Chocolate Chip
Step-by-step explanation:
This can be solved using a system of equations. The two equations are C (chocolate) + O (oatmeal raisin) = 525 and the equation 4C+10=O. Then solving using elimination for systems of equation you can calculate that C=103, then plugging this number into one of the original equation you can calculate that O = 412.
Which domain restrictions apply to this rational expression?
x2+x+6x2+2x−3
Answer:
[tex]Dom\{f(x)\}=\mathbb{R}-\{-3,1\}[/tex]
Step-by-step explanation:
The correct rational expression is [tex]f(x) = \frac{x^{2}+6\cdot x^{2}+6}{x^{2}+2\cdot x-3}[/tex]. From Algebra we know that rational polynomical expressions are continuous except for those values of x such that denominator equals zero. First, we factorize the polynomial at denominator:
[tex]x^{2}+2\cdot x-3 = (x+3)\cdot (x-1)[/tex]
Which means that domain is represented by the set of all real number except -3 and 1.

14x-35+35=4x+15+35
14x=4x+50
14x-4x=4x+50-4x
10x=50
x=5
Answer:
x = 5
Step-by-step explanation:
[tex]7(2x - 5) = 4x + 15[/tex]
[tex]14x - 35 = 4x + 15[/tex]
[tex]14x - 35 - 4x = 15[/tex]
[tex]14x - 4x = 15 + 35[/tex]
[tex]10x = 15 + 35[/tex]
[tex]10x = 50[/tex]
[tex]x = 5[/tex]
The local operations manager for the Internal Revenue Service must decide whether to hire one, two, or three temporary tax examiners for the upcoming tax season. She estimates that net revenues (in thousands of dollars) will vary with how well taxpayers comply with the new tax code just passed by Congress, as follows:
Number of examiners Compliance
Low Normal High
One 50 50 50
Two 100 60 20
Three 150 70 -10
If she uses the Laplace criterion, how many new examiners will she decide to hire?
a. one
b. two
c. three
d. either one or two
e. either two or three
Answer:
If she uses the Laplace criterion, the number of new examiners she will decide to hire is:
c. three
Step-by-step explanation:
a) Data:
Number of Compliance
examiners Low Normal High
One 50 50 50
Two 100 60 20
Three 150 70 -10
b) Outcome Calculations:
Number of Compliance
examiners Low Normal High
One 16.65 (50 *.333) 16.65 (50 *.333) 16.65 (50 *.333) = 50
Two 33.3 (100 *.333) 19.98 (60 *.333) 6.66 (20 *.333) = 60
Three 49.95 (150 *.333) 23.31 (70 *.333) -3.33 (-10 *.333) = 70
c) Decision:
Three has the highest payoff condition and is selected.
d) The Laplace criterion assumes that each compliance state is equally likely to happen. Therefore, it assigns the same weight to each state of compliance. Since there are three states of compliance, we shall assign each state a weight of 0.333. The number of examiners that have the highest payoff condition is three, and therefore, the number "three" is selected.

Write the given linear system in matrix form. Assume X = x y z . dx dt = −3x + 6y − 9z dy dt = 7x − y dz dt = 10x + 6y + 3z
Answer:
Step-by-step explanation:
Consider the system:
[tex]\begin {Bmatrix} \dfrac{dx}{dt}=-3x+6y-9z \\ \\ \dfrac{dy}{dt}=7x -y \\ \\ \dfrac{dz}{dt}= 10 x + 6y + 3z\end {Bmatrix}[/tex]
The matrix form of the system is:
[tex]\begin {bmatrix} \dfrac{dx}{dt} \\ \\ \dfrac{dy}{dt} \\ \\ \dfrac{dz}{dt}\end {bmatrix} = \left[\begin{array}{ccc}-3&6&-9\\7&-1&0\\10&6&3\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right][/tex]
Which can be written as:
[tex]X' = \left[\begin{array}{ccc}-3&6&-9\\7&-1&0\\10&6&3\end{array}\right] X[/tex]
where;
[tex]X' = \begin {bmatrix} \dfrac{dx}{dt} \\ \\ \dfrac{dy}{dt} \\ \\ \dfrac{dz}{dt}\end {bmatrix} \ \ \ \& \ \ \ X = \left[\begin{array}{c}x\\y\\z\end{array}\right][/tex]
