The Bernal leadership class is going to sell spirit t-shirts for students and needs to order a color that most students would like to wear, so they ask every fourth student entering the school about their favorite t-shirt color to make a decision about all Bernal students.
Biased, because some students may not like that color, and thus going off of the most popular opinion is only supporting the most popular color. Adding onto that, not every student even gets to vote since it is only every 4th student.

Answer:
27) 4.2
28) D
Step-by-step explanation:
Answer:
27. A 4.2ft
28. D
Step-by-step explanation:
27. Since this is a right triangle, we can use a^2 + b^2 = c^2
3.1^2 + b^2 = 5.2
b = sqrt(5.2^2 - 3.1^2)
b = 4.2ft A
28. sqrt(10^2 + 50^2) does not equat 54, this is not a right triangle.
Angle J and angle M are base angles of isosceles trapezoid JKLM. If angle J= 15x+9 and angle M=9x+15 find K
Answer:
156°
Step-by-step explanation:
To solve this problem, we first use the relation
15x + 9 = 9x + 15, on collecting like terms, we have
15x - 9x = 15 - 9
6x = 6
x = 1
And if x is equal to 1, then the base angles are 15 + 9 which is 24°.
And finally, to find k, we subtract the calculated angle from 180 and thus
180 - 24 = 156°
Write a set of parametric equations for the equation x = 3y - 2 given that t= x + 3
Answer:
i hope you meant "y" instead of "t" because that would make so much more sense. all you have to do with this is replace "y" in the equation with "x + 3" (this makes the equation x = 3[x + 3] - 2). now, you multiply and combine the like-terms (making x = 3x + 7). you now continue by subtracting 3x from both sides of the equation to make -2x = 7 and dividing to make x = -3.5
Step-by-step explanation:
x = 3(x + 3) - 2
x = 3x + 9 - 2
x = 3x + 7
-2x = 7
x = -3.5

eight less than five times a number is greater than 6
Answer:
8 - 5x > 6
Step-by-step explanation:
Answer is in the problem:
eight = 8
less than = minus ( - )
five times a number = 5x (dont know the number so we put down "x")
is greater than 6 = > 6
does that make sense?
Work out the lengths of side a and side b 8cm and 5 cm 1 triangle 17cm and 12 cm on the other triangle pythagoras
Answer:
a = 9.4 cm
b = 12.0 cm
Step-by-step explanation:
Check the image uploaded for diagram;
For the first diagram, side length a is calculated as follows;
a² = 8² + 5²
a² = 64 + 25
a² = 89
a = √89
a = 9.4 cm ( approximated to 1 decimal place)
For the second diagram, side length b is calculated as follows;
b² = 17² - 12²
b² = 145
b = √145
b = 12.0 cm (approximated to 1 decimal place)
David kicks a soccer ball off the ground and in the air, with an initial velocity of 35 feet per second. Using the formula H(t) = −16t2 + vt + s, what is the maximum height the soccer ball reaches?
Answer:
Step-by-step explanation:
The function for this problem is: h(t) = -16(t)^2 + vt + s h= the height t= time v= velocity s= starting height With the information given, we know that the starting height is 0, since it was from the ground, and the velocity of the ball is 35 feet per second. Inserting the these information into the equation, we get: h(t) = -16(t)^2 + 35t Now the question asks to find the maximum height. It can be done by using a grapher to graph the maximum of the parabola. It could also be done by finding the vertex, which would be the maximum, of the graph by using x= -b/(2a), where b is equal to 35 and a is equal to -16. We get x=35/32, the x-value of where the vertex lies. You can use this value as the t-value in the previous equation to find the h-value of the vertex. When you do, you get h= 19.1 feet, or answer D.
hope this helps

Which descriptions apply to a coordinate plane? Choose more
than one answer.
Cartesian plane
Two-dimensional
Three-dimensional
Extends forever
Perpendicular axes
Parallel axes
The descriptions that apply to a coordinate plane are:
a) Cartesian plane
b) Two-dimensional
d) Extends forever
e) Perpendicular axes.
The descriptions that apply to a coordinate plane are:
Cartesian plane: A coordinate plane is often referred to as a Cartesian plane, named after the mathematician René Descartes, who introduced the concept of using coordinates to represent points in space.
Two-dimensional: A coordinate plane is a two-dimensional space where points are represented using two perpendicular axes (usually labeled as x-axis and y-axis).
Extends forever: The coordinate plane extends infinitely in all directions along the x-axis and y-axis, allowing representation of points with arbitrary coordinates.
Perpendicular axes: The two axes in a coordinate plane are perpendicular to each other, intersecting at the origin (0, 0). The x-axis is horizontal, and the y-axis is vertical.
The description "Three-dimensional" does not apply to a coordinate plane. A coordinate plane is a two-dimensional space, and it does not have a third axis to represent points in three dimensions.
In a three-dimensional space, you would need an additional axis (usually labeled as z-axis) perpendicular to the x-axis and y-axis to represent points in three dimensions.
Hence, The descriptions that apply to a coordinate plane are:
a) Cartesian plane
b) Two-dimensional
d) Extends forever
e) Perpendicular axes.

Ryan and Sheila are preparing to get married. Sheila has a car payment of $297.00 per month, which is 9% of her monthly income. After they are married, Sheila knows that her car payment will only be 5% of their combined monthly income. How much money does Ryan make per month?
Answer:
$2640
Step-by-step explanation:
Sheila's car payment is 9% of her total income.
let i = total income
this equation can be used to represent the information :
9% x i = $297
to determine i, divide both sides of the equation by 9%
$297 / 0.09 = $3300
After the marriage, the car payment which is 3300 would be 5% of the combined income.
let c = combined income
5% x c = $297
c = $297 / 0.05 = $5940
Ryan's income = combined income - Sheila's income
$5940 - $3300 = $2640
