Answer:
Step-by-step explanation:
we can simply find the relative frequency as foloows:
We are given are No piercings, One or two piercings, and More than two piercings. The relative frequency with no piercings is 188/361 = 0.521, the relative frequency for one or two piercings is 82/361 = 0.227. The total has to add to 361, so there are 361−188−82 = 91 students with more than two piercings, and the relative frequency is 91/361 = 0.252. the below table describes each.
Answer:
Step-by-step explanation:
f(x)=x^4+3x^2-4
put x²=y
squaring x^4=y²
f(x)=y²+3y-4
=y²+4y-y-4
=y(y+4)-1(y+4)
=(y+4)(y-1)
so f(x)=(x²+4)(x²-1)
=[x²-(-4)](x²-1²)
=[x²-(4i²)](x²-1²)
=[x²-(2i)²](x²-1²)
=(x+2i)(x-2i)(x+1)(x-1)
[∵a²-b²=(a+b)(a-b)]
Answer: "
-2y³ + 3y²<span>
+ 27y " .
_______________________________________________________Refer to the completed chart below (image attached).</span>
_______________________________________________________Using the completed chart below (image attached), we can write out the terms:
__________________________________________________ y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;
Then, we can combine the "like terms" ;
__________________________________________y³ − 3y³ = -2y³ ;
+9y² + 3y² − 9y² = + 3y² ;
___________________________________________________________to get: -2y³ + 3y² ; and bring down the "+27y" ;
___________________________________________________________ Answer: "
-2y³ + 3y²<span>
+ 27y " . </span>Refer to chart below (image attached).

The y-intercept of the line is (0, 12/7).
In the slope-intercept form, y = mx + b:
m = slope
b = y-intercept
The y-intercept is the point on the line where it crosses the y-axis, and has coordinates of (0, b). It is also the value of y when x = 0.
In the slope-intercept form, the value of b is the y-coordinate of the y-intercept, (0, b).
Therefore, the y-intercept = (0, 12/7).

Answer:
Solve the equation for x.
The simplified system is the arbitrary solution of the original system of equations.
Y=x+14
y=18−x2
Reorder 18
and −x2.
y=−x2+18
Y=x+14
Solve the equation for Y.
Y=−2y+50
x=36−2y
Reorder 36
and −2y.
x=−2y+36
Y=−2y+50
