What is the equation of the given line?
A. Y = -4x
B. X = 4
C. X = -4
D. Y = -4
Answers
Explanation-
The equation goes across the Y axis not the X axis, therefore, you can eliminate B and C. There also is no slope so there should be no variable after the number. You can also eliminate A from there. Leaving you with the correct answer, D.

A roll of a six sided die
Required
Which of the options is true
A) P(Even) = 1/4 and P(Odd) = 3/4
In a die, we have:
[tex]S = \{1,2,3,4,5,6\}[/tex] -- sample space
[tex]E = \{2,4,6\}[/tex] --- Even
[tex]O = \{1,3,5\}[/tex] -- Odd
The probability of even is the number of even sides over total.
i.e.
[tex]P(Even) = 3/6[/tex]
[tex]P(Odd) = 3/6[/tex]
Hence, (a) is incorrect
(b) A) P(Even) = 1/2 and P(Odd) = 3/2
In (a), we have:
[tex]P(Even) = 3/6[/tex]
[tex]P(Odd) = 3/6[/tex]
Simplify each
[tex]P(Even) = 1/2[/tex]
[tex]P(Odd) = 1/2[/tex]
Hence (b) is true
Since (b) is true, (c) and (d) are false

geometry thats finding x y and z of a triangle but my dum self doesn't know this so plz help
Answers
Answer:
[tex]x = \frac{48}{\sqrt{3}}[/tex]
[tex]y = \frac{24}{\sqrt{3} }[/tex]
[tex]z = 24[/tex]
Step-by-step explanation:
___________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
For a triangle with one of it's acute angle α (alpha) , the value of :-
[tex]\sin \alpha = \frac{Side \: opposite \: to \: \alpha }{Hypotenuse}[/tex][tex]\cos \alpha = \frac{Side \: adjacent \: to \: \alpha}{Hypotenuse}[/tex]___________________________________________________________
In the question , first of all lets find the value of z. So,
[tex]\cos 45 = \frac{z}{24\sqrt{2}}[/tex]
[tex]=> \frac{1}{\sqrt{2}} = \frac{z}{24\sqrt{2}}[/tex]
[tex]=> z = \frac{24\sqrt{2}}{\sqrt{2}} = 24[/tex]
Length of the altitude perpendicular to side (z + y) = [tex]\sqrt{(24\sqrt{2})^2 - 24^2} = 24[/tex]
Now , lets find the value x. So,
[tex]\sin 60 = \frac{24}{x}[/tex]
[tex]=> \frac{\sqrt{3}}{2} = \frac{24}{x}[/tex]
[tex]=> x = \frac{48}{\sqrt{3}}[/tex]
Also ,
[tex]\cos 60 = \frac{y}{x}[/tex]
[tex]=> \frac{1}{2} =\frac{y}{\frac{48}{\sqrt{3}}}[/tex]
[tex]=> y = \frac{48}{2\sqrt{3}} = \frac{24}{\sqrt{3}}[/tex]

5) 10³: So you do 10* 10*10= 1,000
so 10³= 1,000
All you are doing is takeing the number and multiplying itself to the power.
6) (-7)⁴= so you are taking the -7 in parenthesis and making it positive, then you are taking the positive 7 and doing 7⁴. Once you do that you get positive 2401.
8) 3+6* (-5) to the second (i dont have the symbol) so you are going to do PEMDAS: Parenthesis, Expression, Multipulcation, Divison, Addition and Subtraction. so it would be 5+6*25to the second. So you do multipulcation first, so do 6*25=150. Then do addition and do 150+3=153
Step-by-step explanation:
5) 10³= 1,000
6)(-7)⁴= 7⁴= 2401
8)3+6* (-5) to the second= 3+6* (5) to the second= 3+6* 25= 6*25= 150+3= 153
Answer to 8 is= 153

A trade school would like to measure the long-term success of their graduates after they leave the school. The school emais a survey requesting information from graduates about their work experience. One question asks graduates to share their annual salary, and the results of the question will be shared in a brochure for incoming
students. Is it likely that the survey results will provide an accurate estimate of mean annual salary for all of the
school's graduates?
The survey will provide a reasonable estimate of mean annual salary because all graduates were sent the email
survey
The survey will likely overestimate mean annual salary because those with higher salanes may be more likely to respond to the survey
The survey will likely underestimate mean annual salary because there may be more graduates with lower
salanes than higher salaries
The survey will likely overestimate the mean annual salary because the email was only sent to graduates with jobs in their chosen feld
Answers
Answer: The survey will likely overestimate mean annual salary because those with higher salanes may be more likely to respond to the survey.
Step-by-step explanation:
We should note that this is voluntary response because despite the fact that the email was sent to the students, a graduate can decide to be part of the sample or not.
In this case, those that have higher salaries will be more likely to respond to their emails than those that have lower salaries. Therefore, the survey will likely overestimate mean annual salary.
