<h2>Answer:</h2>

The statement that is true about the graph is:

The graph does not show a proportional relationship because each point written as ratio gives a different value.

<h2>Step-by-step explanation:</h2>

A graph is said to have a proportional relationship if it is a straight line passing through the origin.

i.e. a variable must be a constant multiple of the other variable.

i.e. y=kx

From the given graph we have a straight line that passes through (0,2) and (2,3)

Hence, the equation of line is:

$y-2=\dfrac{3-2}{2-0}\times (x-0)\\\\\\i.e.\\\\\\y-2=\dfrac{1}{2}x\\\\\\i.e.\\\\\\y=\dfrac{1}{2}x+2$

Hence, the graph does not show a proportional relationship as the equation of the graph is not of the form y=kx

This means that $\dfrac{y}{x}\neq k$

for some constant k.

According to the Internal Revenue Service (IRS), the chances of your tax return being audited are about 6 in 1,000 if your incom

Tamiku [17]

Answer:

The probability that none of these taxpayers will be audited by the IRS is 0.8996 or 89.36%

Step-by-step explanation:

According to given:

Probability of being audited for income less than $50,000 = 6/1000 = 0.006

Therefore,

Probability of not being audited for income less than $50,000 = 1 - 0.006 = 0.994

Similary,

Probability of being audited for income more than $100,000 = 49/1000 = 0.049

Therefore,

Probability of not being audited for income more than $100,000 = 1 - 0.049 = 0.951

Now, for the probability of 2 persons with less $50,000 income and 2 persons with more than $100,000 income, to not being audited, we must multiply the probabilities of not being audited of each of the 4 persons.

Therefore,

Probability that none of them is audited = (0.994)(0.994)(0.951)(0.951)

<u>Probability that none of them is audited = 0.8936 = 89.36%</u>

If one kilogram is 2.2 pounds how many kilograms would it make for 11 pounds

Mila [183]

Answer:

5 kg

Step-by-step explanation:

To solve this problem, we can use the rule of three.

In fact, we know that:

- 1 kilogram is equivalent to 2.2 pounds

- The ratio between the mass in kilograms and in pounds is constant for every value of the mass

- Therefore, the mass in kilograms corresponding to 11 pounds can be found by writing the following equation:

$\frac{1 kg}{2.2 p}=\frac{x}{11 p}$

Where

x is the mass in kilograms corresponding to 11 pounds.

Solving the equation for x, we find:

$x=\frac{(11p)(1kg)}{2.2p}=5 kg$
