Advance pile up trigonometry

Montano1993 [528]

Answer:

see explanation below

Step-by-step explanation:

You have three pairs of shoes (white, brown, and black), and you have 6 pairs of pants ( brown, blue, grey, white, sand, and black)

We use the Fundamental Counting Principle to find the number of possible pant-shoe combinations:

3 * 6 = 18

then we can find the probability of wearing by random selection brown shoes with either blue or grey pants:

prob (brown shoes & blue pants) + prob (brown shoes & grey pants) =

= 1/18 + 1/18 = 2/18 = 1/9

Each answer choice below represents a relation by a set of ordered pairs. In which of the answer choices is the relation a funct

alexdok [17]

Answer:

A - Not Function

B - Function

C - Function

D - Not Function

E - Function

Step-by-step explanation:

For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function

(Consult the diagram below)

As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.

No repetition of x, IT IS A FUNCTION.

No repetition of x, IT IS A FUNCTION.

As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.

No repetition of x, IT IS A FUNCTION.

How do you solve for a y and x intercept?

FrozenT [24]

For a y-intercept, set $x = 0$ in your equation. Remember that a y-intercept intercepts the y-axis, which is found at $x = 0$ . Thus, setting $x = 0$ will give you the place where your equation intercepts the y-axis.

For an x-intercept, do the opposite, set $y = 0$ . This is because the x-axis is found at $y = 0$ . Similar to the y-intercept, this will find you the point where your equation intercepts the x-axis.

Car A travels 702 miles on 12 gallons of gasoline car b travels 873 miles and 15 gallons of gasoline David wants to buy a car wi

Assoli18 [71]

David should buy Car A because it covers more miles in one gallon than Car B

Step-by-step explanation:

Given

Distance traveled by Car A = $d_A = 702\ miles$

Gallons used by Car A = $g_A = 12$

Distance traveled by Car B = $d_B = 873\ miles$

Gallons used by Car B = $g_B = 15$

In order to find the distance traveled on one gallon, we will divide the total distance by number of gallons

So,

Distance traveled by Car A in one gallon = $\frac{702}{12} =58.5\ miles\ per\ gallon$

Distance traveled by Car B in one gallon = $\frac{873}{15} = 58.2\ miles\ per\ gallon$

We can see that Car A travels more distance in one gallon that is 58.5 miles per gallon

So,

David should buy Car A because it covers more miles in one gallon than Car B

Write the whole number that correctly completes the word problem:

irina1246 [14]

Answer:

2/3(two thirds) of the 24 hour day awake, amounts to 24 x 2 / 3 hours awake which is equal to 16 hours awake

Step-by-step explanation:

24 x 2/3

there are many ways to evaluate this mentally, if you know 8x3=24, for instance you can multiply top and bottom of 2/3 by 8 yo gey 24 x 16/24 which is 16 hours
