Y=55

Explanation:

If you’re looking to see how 11 and y would match -9 and -45 you would find the unit rate of -9 and -45.

-9/-9=1
-45/-9=5

So if the y is going up by 5’s it would be 55.

Look at the sequence in the table.

malfutka [58]

Answer:

Step-by-step explanation:

The consecutive values of $a_{n}$ have a common difference d, that is

d = 8 - 3 = 13 - 8 = 18 - 13 = 23 - 18 = 5

This indicates that the sequence is arithmetic.

The recursive formula allows the next term in the sequence to be found from the previous term by adding 5, thus

$a_{n}$ = $a_{n-1}$ + 5 → A

A scale drawing of a door is 2 cm high. If the scale is 1 cm = 4 meters, what is the actual height of the door?

Vanyuwa [196]

2*4= 8 meters

You could multiply every centimeter by the scale of 4 because 1 cm= 4 meters.

I hope this helps!

In Wellington, a city of 360,000 citizens, there has been an outbreak of vampires and werewolves There are 3,000 people infected

Alex17521 [72]

Answer:

0.0286 or 2.86%

Step-by-step explanation:

The total number of people that have werewolfism is 21,000.

Of those 21,000, 600 also have vampirism, while the remaining 20,400 do not. Therefore, the probability that someone has vampirism, given that they have werewolfism is:

$P(V|W)=\frac{N_{V\cap W}}{N_W}\\P(V|W)=\frac{600}{21,000} \\P(V|W)=0.0286=2.86\%$

The probability is 0.0286 or 2.86%.
