If the probability of writing the correct answer to the question on an exam is 2/5, what are the odds against writing the correct answer?

Answers

Answer 1
Answer is  3:2

Explanation

The probability of getting the correct answer is 2/5. This means there are 2 events of getting it right out of 5 events total. Since there are 2 events of getting it right, there are 5-2 = 3 events of getting it wrong.

The odds against getting the right answer is 3:2. We list the number of ways to get it wrong first, a colon, then the number of ways of getting it right.

An item sells for $30 and is on sale for 15% off and the sales tax is 8.2%. What is the final cost to the nearest cent? (Calculate the discounted cost first and then find the tax on the discounted cost.)

Answers

Answer:

$27.59

Step-by-step explanation:

You multiply 30 dollars by 0.85 (1-0.15, with the 0.15 being for the 15 percent off). Which gets you to $25.50, and you then multiply it by 1.082 (the 1.082 being the tax, and the .082 part equating to the 8.2% tax percentage).

Answers

Answer:

A,B,D,E

Step-by-step explanation:

The statements which are true shown below,

Function g is 4 units above function f.Function g has a y-intercept of (0,4)The range of function g is (3, ∞).Function g is positive over the interval (-∞ , ∞ ).

From graph attached below, It is observed that

Graph of function g is 4 units above the graph of parent exponential function.Domain of the function is defined as all the input values for which function is defined. From graph of function g, the domain of function is (-∞ , ∞ )The y- intercept is the point at which graph of function crosses the y-axis. Graph of function g crosses y-axis at (0, 4). Therefore, Function g has a y-intercept of (0,4).Function g increasing over the interval (-∞, 0) .Range of function is known as output values of function. From graph, it is observed that the range of function g is (3, ∞).Since, graph of function g is above x- axis. Therefore, Function g is positive over the interval (-∞ , ∞ ).

A watering can dispenses water at the rate of 0.3 gallon per minute. The original volume of water in the can was 7 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water? (1 point)

{(1, 6.7), (2, 6.4), (3, 6.1)}
{(1, 7.0), (2, 6.7), (3, 6.4)}
{(6.7, 1), (6.4, 2), (6.1, 3)}
{(7.0, 1), (6.7, 2), (6.4, 3)}

Answers

Answer:

The correct ordered pairs are:

{(1, 6.7), (2, 6.4), (3, 6.1)}

Option A is correct.

Step-by-step explanation:

A watering can dispenses water at the rate = 0.3 gallon per minute

The original volume of water in the can = 7 gallons.

Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water?

First making the function:

The the volume of water in the can in gallons is represented by y and  time in minutes is represented by x. Initially the volume is 7 gallons, after than water dispense at rate of 0.3 gallon per minute so, the function will be:

y=7-0.3(x)

Now, putting values to find ordered pairs

So, when time is 1 minute i.e x = 1

y=7-0.3(1)

y=7-0.3

y=6.7

So, when x=1, y=6.7 the ordered pair is: (1,6.7)

when time is 2 minutes i.e x = 2

y=7-0.3(2)

y=7-0.6

y=6.4

So, when x=2, y=6.4 the ordered pair is: (2,6.4)

when time is 3 minutes i.e x = 3

y=7-0.3(3)

y=7-0.9

y=6.1

So, when x=3, y=6.1 the ordered pair is: (3,6.1)

So, the correct ordered pairs are:

{(1, 6.7), (2, 6.4), (3, 6.1)}

Option A is correct.
