Ali and Leila are analyzing the following points. Ali thinks that most of the points are in
quadrant 2 because there are many x-values that are negative. Leila disagrees. Who is
correct?
(−3, 6), (−2, 4), (−3, −1), (−1, −6), (−4, −5), (−2, −7), (−5, −9), (−8, −9), (−12, −3), (2, 4),
(3, 2) and (4, 1).

The inequality for Leila claim is (0.75 × x) > (0.50 × y) and the support claim is x = 100 and y = 10 and that refutes the claim is x = 1 and y = 200

Inequality:

Inequality are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given,

Leila says that 75% of a number will always be greater than 50% of any other number.

Here we need to find the inequality and we also need to find one that supports Leila's claim and one to show that she is incorrect.

Let x and y be two numbers.

Leila says that 75% of a number will always be greater than 50% of any other number.

This means that the inequality is,

=> (0.75 × x) > (0.50 × y)

We know that,

75% of x = 0.75 × x

and

50% of y = 0.50 × y

So,

Numbers that support Leila's claim.

Let x = 100 and b = 10

=> 0.75 × x

=> 0.75 × 100 = 75

and

=> 0.50 × 10 = 5

As we know that, based in on the inequality,

=> 75 > 5

Hence, x = 100 and y = 10 support Leila's claim.

Similarly,

Numbers that refutes her claim.

Let x = 1 and y = 200

=> 0.75 × x

=> 0.75 × 1 = 0.75

and

=> 0.50 × 200 = 100

As we know that,

=> 0.75 < 100

Hence, x = 1 and y = 200 refutes Leila's claim.

The expected value for your profit is 2.53.

The probability is the number that indicates the likelihood that an event will occur and is defined as the ratio of favorable outcomes to all outcomes.

Given,

You can solve for the necessary anticipated value below.

There will be 600 tickets available for purchase overall.

So,

$ 5 each and sell go tickets

one $3,000 grand prize = ( 1/600) × 3000

two $500 second prizes = (2/600) × 500

thirteen $40 third prizes = (13/600) × 40

Any discrete variable X's anticipated value is calculated as:

E(x) = ( 1/600) × 3000 + (2/600) × 500 + (13/600) × 40 + (600-1-2-13/600).0-5

E(x) = 2.53

The expected value for your profit is  2.53.

Using translation concepts, the note E would be louder with a higher amplitude of y, hence constant a has to be multiplied by a positive constant greater than 1.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the function is given by:

y = asin(1320πx)

The intensity of a sound is given by it's amplitude a, hence, to make the sound stronger, we need to vertically stretch the graph of y, which is done when constant a is multiplied by a positive constant greater than 1.

Answer:

h = 10m

Step-by-step explanation:

[tex]A=\frac{bh}{2}[/tex]
[tex]90=\frac{18h}{2}[/tex]

[tex]18h=(90)(2)[/tex]

[tex]h=\frac{180}{18} =10[/tex]

Hope this helps

The formula in terms of h is h = 3V/s^2 and the value of h is 5

The equation is given as

V = 1/3s^2h

Divide both sides of the equation by 1/3s^2

So, we have

h = 3V/s^2

The given parameters are

V = 60 and s = 6

So, we have:

h = 3 * 60/6^2

Evaluate

h = 5

Hence, the formula in terms of h is h = 3V/s^2 and the value of h is 5

The monthly cost will be $62.88 if Cathy is purchasing a DVD player and tv at the local electronic store. The DVD player costs $49.36 and the tv cost $705.20.

What is debt?

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

We know the formula for the monthly payment:

It is given that:

Cathy is purchasing a DVD player and tv at the local electronic store.

The DVD player costs $49.36 and the tv cost $705.20.

If she plans for them in 12 equal payments,

Total cost(combining the cost of the DVD player and TV cost):

= $49.36 + $705.20

= $754.56

Per month payment = $754.56/12

Per month payment = $62.88

Thus, the monthly cost will be $62.88 if Cathy is purchasing a DVD player and tv at the local electronic store. The DVD player costs $49.36 and the tv cost $705.20.

When compared to other scheduling methods for real-time systems, EDF is quite effective. It can maintain all work deadlines while increasing CPU utilization to around 100%.

The earliest deadline first (EDF) algorithm is a dynamic priority scheduling algorithm that is used in real-time systems.

EDF is an optimal algorithm, it will schedule a task set if possible. EDF is also independent of the task's period and can be used to schedule aperiodic tasks because it makes no assumptions about job periodicity. If two jobs have the same absolute deadline, choose one at random.

When compared to fixed priority scheduling techniques such as rate-monotonic scheduling, EDF can guarantee all system deadlines at higher loading. On non-preemptive uniprocessors, EDF is also an optimal scheduling algorithm, but only among scheduling algorithms that do not allow inserted idle time.
