there is a stack of 8 cardseach given a different number from 1-8suppose we select a card from the stack, Replace it, and then Randomly select another card.what is the Probability that the 1st card is an Odd num and the 2nd card is Greater than 6?

Answers

Answer 1

Solution:

The probability of a particular event A occurring from an experiment is obtained from the number of ways that A can occur divided by the total number of possible outcomes. That is;

\(\begin{gathered} P(A)=\frac{n(A)}{n(T)} \\ \text{Where;} \\ P(A)=\text{ probability of event A} \\ n(A)=\text{ number of possible ways event A can occur} \\ n(T)=\text{ total number of possible outcomes} \end{gathered}\)

In a stack of 8 cards with different numbers;

The probability that the first card is an odd number and the second card is greater than 6 is the product of the probability of odd number and the probability of greater than 6. That is;

\(P(\text{Odd and greater than 6)}=P(odd)\times P(greater\text{ than 6)}\)

We have;

\(\begin{gathered} P(\text{odd)}=\frac{n(\text{odd)}}{n(T)} \\ P(\text{odd)}=\frac{4}{8} \\ P(\text{odd)}=\frac{1}{2} \end{gathered}\)

Also,

\(\begin{gathered} P(\text{greater than 6)=}\frac{\text{n(greater than 6)}}{n(T)} \\ P(\text{greater than 6)=}\frac{\text{2}}{8} \\ P(\text{greater than 6)=}\frac{1}{4} \end{gathered}\)

So, the probability that the first card is an odd number and the second is greater than 6 is;

\(\begin{gathered} P(\text{Odd and greater than 6)}=\frac{1}{2}\times\frac{1}{4} \\ P(\text{Odd and greater than 6)}=\frac{1}{8} \end{gathered}\)

FINAL ANSWER:

\(\frac{1}{8}\)

There Is A Stack Of 8 Cardseach Given A Different Number From 1-8suppose We Select A Card From The Stack,

The solution to the inequality f(x²-2) < f(7x-8) over D₁ = (-∞, 2) is:

-∞ < x < 1 or 1 < x < 6 or 6 < x < 2

Solving Inequality in a given domain

Given the inequality,

    f(x²-2) < f(7x-8) over D₁ = (-∞, 2)

We need to find the values of x that satisfy this inequality.

Since we know that f is increasing over its domain, we can compare the values inside the function to determine the values of x that satisfy the inequality.

First, we can find the values of x that make the expressions inside the function equal:

x² - 2 = 7x - 8

Simplifying, we get:

x² - 7x + 6 = 0

Factoring, we get:

(x - 6)(x - 1) = 0

So the values of x that make the expressions inside the function equal are x = 6 and x = 1.

We can use these values to divide the domain (-∞, 2) into three intervals:

-∞ < x < 1, 1 < x < 6, and 6 < x < 2.

We can choose a test point in each interval and evaluate

f(x² - 2) and f(7x - 8) at that point. If f(x² - 2) < f(7x - 8) for that test point, then the inequality holds for that interval. Otherwise, it does not.

Let's choose -1, 3, and 7 as our test points.

When x = -1, we have:

f((-1)² - 2) = f(-1) < f(7(-1) - 8) = f(-15)

Since f is increasing, we know that f(-1) < f(-15), so the inequality holds for -∞ < x < 1.

When x = 3, we have:

f((3)² - 2) = f(7) < f(7(3) - 8) = f(13)

Since f is increasing, we know that f(7) < f(13), so the inequality holds for 1 < x < 6.

When x = 7, we have:

f((7)² - 2) = f(47) < f(7(7) - 8) = f(41)

Since f is increasing, we know that f(47) < f(41), so the inequality holds for 6 < x < 2.

Therefore, the solution to the inequality f(x²-2) < f(7x-8) over D₁ = (-∞, 2) is:

-∞ < x < 1 or 1 < x < 6 or 6 < x < 2

What is an Inequality Equation?

Mathematical expressions with inequalities are those in which the two sides are not equal.

Contrary to equations, we compare two values in inequality.

Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Two expressions in inequality aren't always equal, which is denoted by the symbols >, <, ≤, or ≥.

So, let's say the inequality equation looks like this: A

Right now, A is valued at

Let p be used to representing the initial number.

P equals 11, so

Let q be used to representing the second number.

Q has a value of -11.

-11 and 11 are both numbers that are greater than zero.

Then, 11 > -11 ... (1)

A has a value of 11 > -11.

Therefore, using the inequality rule we know that 11 is greater than -11, (11 > -11).

On studing about the nature of system of linear equation the correct option is B.

How to determine the nature of system of linear equations of two variables?

Consider the following two linear equations:

\(a_1x + b_1y + c_1 = 0a_2x + b_2y + c_2 = 0\)

(1) If  \(\frac{a_1}{a_2}\ne \frac{b_1}{b_2}\) them the system of equations have unique solution.

(2) If  \(\frac{a_1}{a_2}= \frac{b_1}{b_2}=\frac{c_1}{c_2}\) them the system of equations have infinitely many solutions.

(3) If  \(\frac{a_1}{a_2}= \frac{b_1}{b_2}\ne \frac{c_1}{c_2}\) them the system of equations have no solution.

Now, consider the given equation.

2x+3y = -17

y = x - 4

Rearrange the above equation as follows:

2x+3y +17 = 0

x - y - 4 = 0

Now, on comparing,

\(a_1=2, a_2=1, b_1=3, b_2=-1, c_1=17, c_2=-4\)

Now, take ratio as follows:

\(\frac{a_1}{a_2}=\frac{2}{1}\\\frac{b_1}{b_2}=\frac{3}{-1}\\\frac{c_1}{c_2}=\frac{17}{-4}\)

It satisfies the first condition hence, there is one solution for the system of equations.

2y3 + my2 + 11y + m + 3 is exactly divisible but (2y-1) is

\(\large\underline{\sf{Solution-}}\)

Given that:

\(\sf p(y) = 2y^3+my^2+11y+m+3 \)

We are also given that, p(y) is divisible by 2y - 1.

So, 2y - 1 is a factor of p(y).

\(\sf\longmapsto 2y-1=0\)

\(\sf\longmapsto y=\dfrac{1}{2}\)

So, 1/2 is a zero of p(y).

\(\sf\longmapsto p(1/2) =0 \)

\(\sf\longmapsto p(y) = 2y^3+my^2+11y+m+3 \)

\(\sf\longmapsto p\left(\dfrac{1}{2}\right) = 2\left(\dfrac{1}{2}\right)^3+m\left(\dfrac{1}{2}\right)^2+11\left(\dfrac{1}{2}\right)+m+3 \)

So,

\(\sf\longmapsto p\left(\dfrac{1}{2}\right) = 2\left(\dfrac{1}{8}\right)+m\left(\dfrac{1}{4}\right)+11\left(\dfrac{1}{2}\right)+m+3 \)

\(\sf\longmapsto p\left(\dfrac{1}{2}\right) = \dfrac{1}{4}+\dfrac{m}{4}+\dfrac{11}{2}+m+3 \)

\(\sf\longmapsto p\left(\dfrac{1}{2}\right) =\dfrac{1}{4}+\dfrac{m}{4}+\dfrac{22}{4}+\dfrac{4m}{4}+\dfrac{12}{4} \)

\(\sf\longmapsto 0 =\dfrac{1+m+22+4m+12}{4} \)

\(\sf\longmapsto 0 =\dfrac{5m+35}{4}\)

\(\sf\longmapsto 5(m+7)=4\times0\)

\(\sf\longmapsto 5(m+7)=0\)

What is the proportion of students that have already NOT found a job (rounded off to two decimals)? [3]

Answers

The proportion of Arts majors who have not found a job is 8%, rounded off to two decimal places.

To find the proportion of Arts majors who have not found a job, we first need to calculate the total number of students who have not found a job.

The total number of students who have not found a job would be 1500 - 1380 = 120.

To calculate the proportion of students who have not found a job, we can divide the number of students who have not found a job by the total sample size:

The proportion of students who have not found a job = 120 / 1500 = 0.08 or 8%.

Therefore, the proportion of Arts majors who have not found a job is 8%, rounded off to two decimal places. This suggests that a majority of the graduating Arts majors from the University of Western Cape have found employment before their graduation.

Question:

Given the demand equation p=190/q+10 where 10<0<85, for what value of q is | n | a maximum? For what value is it minimum?

Answers

The maximum and minimum value of η at q = 10 and q = 85 respectively.

The demand equation is p = 190/ (q + 10) where 10 < 0 < 85.

η is the elasticity of demand.

Then, the elasticity of demand is given as:

η = ( dq/ dp) × ( p / q )

Now, we have p = 190/ (q + 10)

Therefore,

p ( q + 10 ) = 190

pq + 10p = 190

q = ( 190 - 10p ) / p

Now,

dq / dp = ( d/dp ) ( ( 190 - 10p ) / p )

dq / dp =  ( -190/ p² )

Substituting these values in the elasticity demand,

η = ( dq/ dp) × ( p / q )

η = ( -190/ p² ) × ( p / q )

η = ( -190/ pq )

η = ( -190/ [190 / (q + 10 ) ]q )

η = [ - ( q + 10 ) / q ]

| η | = | - ( q + 10 ) / q |

η =  ( q + 10 ) / q = 1 + 10/q

The critical point is when | η' | = 0.

η' = ( d / dq ) ( 1 + 10/q )

η' = - 10/ q²

- 10/ q² = 0

Hence, - 10/ q² is not defined.

Therefore, the function is not defined at q = 0.

Therefore, q = 0 is not a solution.

We have 10 ≤ q ≤ 85

The value of functions at the endpoint,

At q = 10,

η = ( 1 + 10/q )

η = ( 1 + 10/10 )

η = 1 + 1 = 2

At q = 85,

η = ( 1 + 10/q )

η = ( 1 + 10/85 )

η = 1.11764

Therefore, the absolute value of the elasticity of demand is maximum at q = 10.

The absolute value of the elasticity of demand is minimum at q = 85.

the equation below represents the total price of Michigan State University per semester where c represents the number of classes and t represents the total cost for the semester including a one time fee for room and board

Answers

The equation that represents the total price of Michigan State University per semester is determined by the number of classes taken (c) and the total cost for the semester, which includes a one-time fee for room and board (t).

The equation captures the relationship between these variables and calculates the overall cost for a student attending the university. It is important to note that the equation provides a quantitative representation and does not take into account other factors such as scholarships, financial aid, or additional expenses. Therefore, the equation serves as a useful tool for estimating the total cost of attending Michigan State University, allowing students and their families to plan and budget accordingly for their education.

In the trapezoid, find the measure of yº
(6x + 20°? Can y’all help?

In the trapezoid, find the measure of y(6x + 20? Can yall help?

Answers

Answer:

y=64°

Step-by-step explanation:

Within a trapezoid, the angles on the same side of a leg add up to 180:

(6x+20)+(4x)=180

6x+4x=180-20

10x=160

x=16

Since the base lines are parallel, and the leg lines are equal in length, y=4x

y=4(16)

y=64°

Can some please explain how to solve this? Thank you. 1/2(3/2y+1/3)=-1/2(y-5/2)

Answers

y = 13/15

First, write the equation:
1/2 (3/2y+1/3) = -1/2 (y-5/2)
First, distribute 1/2 by multiplying that by 3/2y and 1/3. At the same time, distribute -1/2 by multiplying that by y and -5/2. It should look like:
3/4y + 1/6 = -1/2y + 5/4
When solving to find a variable, you want to get the variable to only one side of the equation. Add 1/2y to both sides of the equation. However, when you have to add 3/4y + 1/2y, you’ll notice that the denominators are different, meaning you have to change them to make the denominators the same. Multiply 1/2 by 2 to get 2/4. Now, add 3/4 + 2/4 to get 5/4. This is what you should now have:
5/4y + 1/6 = 5/4
Next, you want to try and get the variable number by itself. As you can see, 1/6 prevents it from being by itself on one side of the equation. Subtract 1/6 from both sides. Once again, you cannot do this because the denominators aren’t the same. Multiply 5/4 by 6 and 1/6 by 4 to get 30/24 minus 4/24, which equals 26/24. You can now simplify that to 13/12. Now your equation should look like this:
5/4y = 13/12
Divide both sides of the equation by 5/4 to get y = 13/15. That is your final answer. Hope this helped! Sorry if this answer was rlly long lol
