(2,1), (4,2), (6,3) or (8,4) are the numbers we will use to find the first differences which will give us the unit rate

2/1 = 2
4/2= 2
6/3= 2
8/4= 2

therefore this graph is linear and its unit rate is 2.

Answer:

8 x 13 = 104 yd^2

Step-by-step explanation:

To find the area of a rectangle we use the basic formula:

L x W

In this case 13 is your width and 8 is your length, multiply the two given lengths to get your area which is 104.

What effect does a negative have when placed Inside the parentheses?
Murljashka [212]

Answer: it makes a horizontal shift. for example: (x-4) means the graph moved 4 units to the RIGHT.

Step-by-step explanation: it is essentially the opposite of what you think if it's inside the parenthesis.

A) Business means the process of earning money, so she earned $350 at first time, so her initial value would be: $350

Rate of change = 750 - 350 / 350 * 100
= 400 / 350 * 100
= 40000 / 350
= 114.28

Now, There are 4 years between 2014 & 2010 so it will be:
= 114.28 / 4 = 28.57

In short, Your Answer would be 28.57% per year

B) Equation would be: Y = x + 0.2857x
Where, x = number of year

Hope this helps!

If xy=0, what must be true about either x or y
evablogger [386]

Answer:

either x or y must equal 0​

Step-by-step explanation:

ts given that xy = 0

Remember that product of two numbers can be zero only if:

Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.

So, if the product of x and y is equal to 0 there are two possibilities:

Both x and y are equal to 0

Either x or y must be equal to 0

Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.

Hence, the condition which has to be true in all cases for xy = 0 is:

either x or y must equal 0​

An airline finds that 5% of the persons making reservations on a certain flight will not show up for the flight. If the airline
vivado [14]

Answer:

The answer to the question is;

The probability that a seat will be available for every person holding a reservation and planning to fly is 0.63307.

Step-by-step explanation:

Let the sample size =n = 100

The success probability = 5 % = 0.05

Number of tickets sold = 105 tickets

In the case where there the airline has found that 5 % will not show up, then every passenger should have  a seat, we have  

A Binomial distribution is appropriate where there is a chance for a certain number of successful outcomes from a number of independent trails

However n·p and n·q must be ≥ 5 for there to be a normal approximation of a Binomial distribution thus

n·p = 105×0.05 =  5.25 ≥ 5

and n·q = n(1 - p) = 105 (1 - 0.05) = 99.75 ≥ 5

As the requirements are met, we can proceed with the approximation of the Binomial distribution by the normal distribution

 z = \frac{x-np}{\sqrt{np(1-p)}  } = \frac{4.5 - 105*0.05}{\sqrt{105*0.05(1-0.05)} } =  - 0.3358

We therefore have P(x ≥ 5) = P( x > 4.5) = P(z > -0.34) = 1 - P(z < -0.34) = 1 -0.36693 = 0.63307

Another way to solve the question is as follows

p = 0.95 q = 0.05

μ = np = 0.95*105 = 99.75, σ = \sqrt{npq} = 2.233

P (x≤100) = P(z = P(z<0.34) = 0.63307.
