Answer:
x+3y=-9
Step-by-step explanation:
-2(x+3y)=18
x+3y=18/-2
x+3y=-9
We can conclude that samples won’t affect how many bottles of wine a customer will buy.
Answer:
1832 miles
Step-by-step explanation:
First we need to find the angle between the routes of the planes.
If one is N30°W and the other is S45°W, we can find the angle between the routes with the following equation:
30 + angle + 45 = 180
angle = 105°
Then, we need to find the distance travelled by each plane, using the formula:
distance = speed * time
The time is 1.5 hours, so we have that:
distance1 = 800 * 1.5 = 1200 km
distance2 = 750 * 1.5 = 1125 km
Now, to find the distance between the planes, we can use the law of cosines:
distance^2 = 1200^2 + 1125^2 - 2*1200*1125*cos(105)
distance^2 = 3356214.43
distance = 1832 miles
Answer:
No, because the probabilities of drawing a vowel versus a constant are not equally likely.
Step-by-step explanation:
Each number in a random number generator is equally likely. If she assigns only the number 1 to vowels and only the number 2 to consonants, she will get results showing that they are equally likely.
In reality, 5 of the 26 letters are vowels (not including y). The teacher should assign numbers 1 through 5 to vowels, and numbers 6 through 26 to consonants. This will be a fair representation.
