Event E is the two numbers are not even.
The complement of event E is the two numbers are even.
The number of outcomes of the complement of event E is 5 * 4 = 20, but since the outcome 2, 4 is the same as the outcome 4, 2, you need to divide the number of outcomes by 2.

Answer: 10

Answer:

The answer is A= 10

Step-by-step explanation:

The complement of E is when the two numbers are even.

(2, 4), (2, 6), (2, 8), (2, 10), (4, 6), (4, 8), (4, 10), (6, 8), (6, 10), (8, 10)

Thus, there are 10 outcomes where the numbers are even.

Goal: Find a reasonable domain and range for each function.

slamgirl [31]

D(x) = 32x......ur range will be ur d(x) values and the domain will be ur x values.....where d(x) = total distance and x = gallons.
So we already know that ur car's fuel tank holds 17 gallons....therefore, ur domain has to be 17 gallons or less...but it cant be negative.
so ur domain is : 0 < = x < = 17

now for ur range....since the car only holds 17 gallons....d(x) = 32(17) = 544 miles....thats the farthest it can go...therefore it can go from 0 to 544 miles....so ur range is : 0 < = d(x) < = 544

or u could write it as : domain = (0,17) with 0 representing an empty tank and 17 representing a full tank.....and ur range = (0,544) with 0 representing 0 miles driven and 544 representing 544 miles driven

A submarine left hawaii and travels east at an average speed of 10 mph. An aircraft. Carrier left at the same time and traveled

Rina8888 [55]

Answer:

10 hours

Step-by-step explanation:

Given:

Average speed of submarine = 10 mph

Speed of carrier in the opposite direction = 20 mph

Distance between the submarine and carrier = 300 mi

To find:

The time taken so that the distance between them is 300 mi ?

Solution:

The relative speed when they are traveling in opposite direction = 10+20 = 30 mph

Formula:

$\text{Time }=\dfrac{\text{Distance Traveled}}{\text{Speed}}$

$\text{Time }= \dfrac{300}{30} = \bold{10\ hours}$

So, the answer is 10 hours.

What is the slope of the line y+4 = 3(x+6)

Akimi4 [234]

Answer:

Step-by-step explanation:

First you gotta take the equation and bring it to the following form:

$y = ax + b$

The slope of the line is the coefficient of x, a.

In other words:

$y + 4 = 3(x + 6) \\ y + 4 = 3x + 18 \\ y = 3x + 18 - 4 \\ y = 3x + 14$

So, as we can see, the number infront of x is 3. That is to say that the slope of this line is equal to 3.

John and 3 friends are going out for pizza for lunch. They split one pizza and 4 large drinks. The pizza cost $13.00. After usin

IgorLugansk [536]

A.4d+$13.00-$6.00=$13.20 is your answer.

The reason for this is :

Step One : Start with what you know
($13.00-$6.00)

Then make a full equation based on what you need to find out.($7.00+4d)/4=(13.20)/4
Start simplifying.
(1.75+d)-1.75=(3.3)-1.75
Continue to simplify for your answer.
d=1.55
1.55 is the answer.
(A is your answer.)
