The time taken by Oliver to complete the work is less than or equal to twice the work done by Karissa.

Option B shows the correct equation of inequality to write the time taken to complete the work.

Inequality can be defined as a relation that makes a non-equal comparison between two numbers or other mathematical expressions.

Given that Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Also, the time taken to complete the project is,

Oliver = 4 and one-fourth hours

Karissa = K hours

As per the given condition, the work done by Oliver should not be more than twice the work done by Karissa. It can be equal or less. So we can write this in equation form as,

Oliver [tex]\leq[/tex] 2 Karissa

[tex]4\dfrac {1}{4} \leq 2K[/tex]

Hence Option B shows the correct equation of inequality to write the time taken to complete the work.

The probability of this occurring is 1/7

Step-by-step explanation:

Okay, here is a probability question.

From the question, we can identify the following;

Total number of socks = 2 + 4 + 2 = 8 socks

Since we are not given the order in which the socks was worn, we can assume any order.

Let’s say the right leg socks was worn first.

From the question, the socks on the right leg is a brown one.

So now let’s calculate the probability of selecting a brown socks out of the mix

That would be ;

number of brown socks/ total number of socks = 4/8 = 1/2

Now, for the left foot, we are having white sock here.

Kindly recall that since we already have a sock on the right foot, we have 7 socks left to pick from.

Now we need the probability of picking a white sock from the total 7. That would be ; 2/7

So the probability of both action occurring is simply the product of both probabilities and that is ;

1/2 * 2/7 = 1/7

Answer:

Yes it is.

Step-by-step explanation:

The minimum point of the function y=f(x)+3 is at (-1 , 0 ) .

The biggest and lowest value of a function, either inside a specific range (the local or relative extrema) or on the entire domain, are generally referred to as extrema (plural of extremum) in mathematical analysis (the global or absolute extrema). One of the first mathematicians to suggest the general method of adequacy for determining the maxima and minima of functions was Pierre de Fermat.

The maximum and minimum of a set are the greatest and least items in the set, as described by set theory. There are no minimum or maximum values in unbounded infinite sets, such as the set of real numbers.

Say that (x,y) = where y = f(x) minimum occurs at (-1,-3). As a result, for all other x inside its domain of definition, y= f(x) >=-3

y = f(x) + 3 simply elevates the graph of y by 3 and increases the value of y for any x. Its minimum x-value remains at -1, and its value for y is f(3) + 3 = -3 + 3 = 0. as a result, new minimum =(-1 , 0 ) .

From x- intercepts  it was possible to find the formula of the parabola: x²-1.69=0.

The quadratic function can be represented by a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

From the sum and product of the roots in a quadratic function it is possible to write your respective equation. Since:

This question gives the root since it informs the x- intercepts (1.3,0) and (-1.3,0). Then, the roots are: x1=1.3 and x2= -1.3.

Hence, you should write the equation in factors from the known roots. See: (x-1.3) * (x+1.3)=0. Multiplying the factor, you will have:

x²+1.3x-1.3x-1.69=0

x²-1.69=0

You can check the previous result from :

the sum of the roots (S) will be 1.3-1.3=0.

the product of the roots (P) will be 1.3*(-1.3)=-1.69.

So, the formula of  the parabola is x²-1.69=0. The attached figure shows the x-intercepts and y-intercept  informed.
