Answer:8
Step-by-step explanation:
There are 12 of the next 12 trains would expect to be full.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Based on the information provided, it seems that 12 out of the last 18 trains to pull into Castroville Station were full, which is a proportion of 12/18 or 2/3.
Therefore, if the same proportion of full trains holds in the future, one would expect 2/3 or 8 of the next 12 trains to be full.
This prediction is based on the assumption that the proportion of full trains remains constant.
Thus, there are 12 of the next 12 trains would expect to be full.

Find the values of x and y.
Answer:
Step-by-step explanation:
y = 5
All sides measure the same So 8y= 40 y = 5
x = 30 degrees
The straight line of 40+40 is a straigth angle of 180 Each angle of equilateral triangle is 60 degrees.So its supplementary is 120.The other 2 angles need to add to 60 (30 each) to sum 180 in a triangle

Three boxes of cereal are shared equally among
8 boys. What fraction of a box does each boy get?
Answer:
3/8
Step-by-step explanation:
We want to find out how much each person gets per box, so all we have to do is divide the three boxes by three and the 8 by three to get how much each person gets. When we do that, we get 3/8. Literally, that means each boy gets 3/8 of a box of cereal.

The farmer walks by the pen with the chickens and pigs. He counts 18 heads and 50 feet. How many of each, chicken and pigs, are there?
Answer:
chickens = 11
pigs = 7
Step-by-step explanation:
this would be solved using simultaneous equation
let c = chicken .
p = pigs
A normal pig and chicken both have 1 head. thus :
c + p = 18 equation 1
A normal pig has 4 legs and a normal chicken has 2 legs. Thus
2c + 4p = 50 equation 2
multiply equation 1 by 2
2c + 2p = 36 equation 3
subtract equation 3 from 2
2p = 14
p = 7
substitute for p in equation 1
c + 7 = 18
c = 11

a bike rental company charges $12, which includes the first 30 minutes of biking. thereafter, the company charges an additional $0.25 per minute. write a numeric sequence for the first 5 minutes of the 30 minutes.
Answer:
0.4, 0.8, 1.2 ,1.6 ,2.0
Step-by-step explanation:
First we have to find what the question is really asking and get rid of unwanted or not needed information. It is asking to write a numeric sequence for the first 5 minutes of the 30 minutes.
Second we need to find the pattern. So lets divide $12 by 30. That will equal 0.4 a minute.
Last we add 0.4 for each minute. 0.4 is the first, then 0.8 is 2 minutes, then 1.2 and etc.
The numeric sequence is 0.4, 0.8, 1.2 ,1.6 ,2.0
The calculation is as follows:
Here we have to divide $12 by 30. That will equal 0.4 a minute.
Now if we add 0.4 for each minutes
So the series be like
0.4 for the first, 0.8 is 2 minute and so on.

The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3. If
there were 21 Laker fans, how many Warrior fans are there
Answer:
35
Step-by-step explanation:
Create a proportion where x is the number of Warrior fans
[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{21}[/tex]
Cross multiply and solve for x
105 = 3x
35 = x
So, there were 35 Warrior fans
Answer:
[tex] \bf\huge warrior \: fans = 35[/tex]
Step-by-step explanation:
Given that :The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3.If there were 21 Laker fans.to find :how many Warrior fans are there.let us assume :warrior fans is X .explanation :finding the warrior fans
⟼ warrior : laker fans = 5 : 3 = x : 21
⟼ 5 : 3 = x : 21
⟼ [tex]\frac{5}{3} \times \frac{x}{21} [/tex]
⟼ x = 5 × 7
⟼ x = 35.
⟼ warriors fans = 35.
∴ laker fans is 21 and warriors fan is 35.
∴ warriors : laker fans = 5 : 3 = 35:21.
HELP NO LINKS Jesse wants to start driving himself to and from school each day his parents want to know how much driving time would be involved so Jesse surveyed for neighbors who live on his block and drive to school data he collected is displayed in the table below
175 minutes of driving time would be involved for Jesse according to the survey.
What are the basic rules of surveying?Some basic rules of surveying are:
Define a clear, attainable goal for your survey.Keep the more personal questions to the end. Don't let your survey get too long. Focus on using closed-ended questions. Consider including a survey incentive. Don't ask leading questions. Keep your answer choices balancedGiven, Jese wants to start driving himself to and from school each day He surveyed neighbors who live on his block and drive to school data.
For better understanding, a picture is attached below.
Add up the 8 different times then divide by 4 to get the average driving time for 1 day:
⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138
⇒ 138 ÷ 4 = 34.5 mins
Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:
⇒ 34.5 x 5 = 172.5 minutes
As 172.5 ≈ 175 minutes, the nest response is 175 minutes
Therefore, According to the study, Jesse would require 175 minutes of driving time.

The distance between the two points is 10.3
Step-by-step explanation:
To find the length of the line joining the two points, we are going to use the distance formula
Mathematically, we have this as;
D = √(y2-y1)^2 + (x2-x1)^2
From the question;
(x1,y1) = (-3,4)
(x2,y2) = (2,-5)
Thus, we have it that;
D = √((-5-4)^2 + ((2-(-3)^2
D = √81 + 25
D = √(106)
D = 10.3
Which statement is correct regarding independent events?
OTwo events are independent if they have no outcomes in common and cannot occur at the same time.
OTwo events are independent if they have outcomes in common and can occur at the same time.
OTwo events are independent if the outcome of the first event does not affect the outcome of the second event.
O Two events are independent if the outcome of the first event affects the outcome of the second event.
Answer:
Two events are independent if the outcome of the first event does not affect the outcome of the second event.
Step-by-step explanation:
two events are independent if the occurrence or outcome of the first event does not affect the outcome or occurrence of the second event.
for example, if you flip a coin the first time and the outcome is a head and you flip a second time and you get a tail. the occurrence of these two event are independent of each other. Thus they are independent events
two outcomes are dependent if the outcome one event is determined by the outcome of the first event.

answer this qustion plz and if get right i might give you brainlist
Answer:
A
Step-by-step explanation:
SO right off the bat it cannot be c, for they do definatly change.
Next, lets find out how much they change by.
The median would now be 120. Since adding 1 more number would make it just 120. Instead of it being 120+130/2.
This is a decrease of 5. Because we can just subtract normal number by new number: 125-120=5.
Now, the mean is already 500/4. This equals 125.
So lets add 0 to that. So now we must divide it by 1 more number, 4+1=5.
That is 500/5. This equals 100.
This is a decrease of 25. Because we can again subtrasct the normal number by the new number: 125-100=25
That is 5x more of a decrease than the mean.
SO it must be A, since the mean decreased more than the median.
