Answer:
-0.25268 rad + 2πn , 3.394273 rad + 2πn
≈ - π /12 + 2πn, π + 2πn
Step-by-step explanation:
sin( x ) = -0.25
x = sin^-1 ( -25 )
The solutions of the equation sin( x ) = -0.25 are :
X = -0.25268rad + 2πn , 3.394273rad + 2πn
≈ - π /12 + 2πn, π + 2πn

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.

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.

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
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

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.
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.
