The answer you are looking for is 15/32.
To find this answer, you must first find the Least Common Denominator. The least common denominator of these 2 fractions can be found by simply multiplying the 2 given denominators together. 5 * 8 = 40.
Now that you found the LCD, you can start to solve the equation. To get 40 as the denominator for 3/8, you multiply the fraction by 5/5.
3/8 * 5/5 = 15/40.
To get 40 as the denominator for 4/5, you multiply it by 8/8. 4/5 * 8/8 = 32/40.
Finally, you divide 15/40 by 32/40. The denominators cancel out, so the numerator becomes 15 and the denominator now becomes 32.
So your answer is 15/32 (which cannotbe simplified)

Mrs. Gilbert is interested in determining how many students spend 4 or more hours doing homework each week. She asks every student who earned Honor Roll for the first semester. Is her survey biased or unbiased?
A. biased, because she didn't ask random students
B. unbiased, because she asked every student on honor roll
C. biased, because she only asked students on honor roll
D. unbiased, because first semester is over
Answer:
C. Biased, because she only asked students on honor roll.
Step-by-step explanation:
Since Mrs. Gilbert's goal was to find how many students that spent >4 hours and not how many students that earned Honor Roll that spent >4 hours, the data is biased. Choose C.

How do I draw and determine the equation of a trend line on a scatterplot
Step-by-step explanation:
Step 1: Draw your trend line.
You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:
trend line equation
Step 2: Locate two points on the line.
Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.
For the trend line that we just drew, we can see these two easily identifiable points.
trend line equation
We can easily identify these two points as (3, 3) and (12, 6).
Step 3: Plug these two points into the formula for slope.
The formula for slope is this one:
trend line equation
We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:
trend line equation
So our slope is 1/3.

A right-angle triangle, with two sides adjacent to the right angle labeled x and y respectively, and the hypotenuse is labeled 12 times square root of 3. The angle between the hypotenuse and the side labeled x measures 30 degrees. Find the values of $x$ and $y$ . Write your answers in simplest form.
Answer:
y = 6(sq rt 3)
x = 18
Step-by-step explanation:
y = (0.5)(12)(sq rt 3) = 6(sq rt 3)
x = (0.866)(12)(sq rt 3) = (10.392)(sq rt 3) = sq rt 324
reduced
x = 18
The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of x and y is 18 and 6√3 units respectively.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
Let the side with label x be the base of the triangle and y be the perpendicular.
As the length of the base is x while the angle is 30°, and the length of the hypotenuse is 12√3, therefore, the value of x can be written as,
[tex]Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Cos (30^o)=\dfrac{x}{12\sqrt3}\\\\\\Cos (30^o) \times {12\sqrt3}={x}\\\\x = {12\sqrt3} \times \dfrac{{\sqrt3}}{2}\\\\x = 18[/tex]
Now, as we know that the length of the perpendicular side is y, therefore, the value of y can be written as,
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Sin (30^o)=\dfrac{y}{12\sqrt3}\\\\\\Sin (30^o) \times {12\sqrt3} ={y}\\\\\\y = \dfrac{1}{2} \times 12\sqrt3\\\\\\y = 6\sqrt3[/tex]
Hence, the value of x and y is 18 and 6√3 units respectively.

need help what is the equation of the purple line
Answer:
y=-2/5x +8
Step-by-step explanation:
use y=mx+b look at where the line intercepts with the y-axis and that is at 8 so that is your b. Then find two points and count how many down or up it is to get from the higher up point (i usually use the one that intercepts at the y-axis) to same line as the other point, in this case thats down two. Then count how many to the right it is and in this case it is 5. so since it went down thats -2 over 5 so then you just fill that into the y=mx+b and you should get y=-2/5x+8

Consider the following formula y−p/2=e. Rearrange the formula to solve for "p":
Answer:
p = 2y - 2e
Step-by-step explanation:
Eliminate the fraction by multiplying all terms by 2:
2( y−p/2=e) = 2y - p = 2e
Now subtract 2e from both sides, obtaining: 2y - 2e = 0.
Finally, add p to both sides: p = 2y - 2e

Write a System of Equations to solve the following problem:
The county fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 13 vans and 2 buses with 211 students. High School B rented and filled 4 vans
and 4 buses with 268 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
#students each VAN can carry:
#students each BUS can carry:
Answer:
each van carries 7 students
each bus carries 60 students
Step-by-step explanation:
let v = # students in a van
let b = # students in a bus
system of equations:
13v + 2b = 211
4v + 4b = 268
I multiplied the 1st equation by -2 to eliminate the 'b' terms
-26v - 4b = -422
+ 4v + 4b = 268
-22v = -154
v = 7
substitute '7' for 'v':
4(7) + 4b = 268
28 + 4b = 268
4b = 240
b = 60
Answer:
13v + 2b = 211
4v + 4b = 268
#students each VAN can carry: 7
#students each BUS can carry: 60
Step-by-step explanation:
Let v = number of students in each van.
Let b = number of students in each bus.
High School A:
13v + 2b = 211
High School B:
4v + 4b = 268
The system of equations is
13v + 2b = 211
4v + 4b = 268
We will solve this system of equation with the addition method.
Write the first equation as it is. Divide both sides of the first equation by 2 and write it below the first equation. Then add the equations.
13v + 2b = 211
(+) -2v - 2b = -134
----------------------------
11v = 77
Divide both sides by 11.
v = 7
Substitute 7 for v in the first original equation and solve for b.
13v + 2b = 211
13(7) + 2b = 211
91 + 2b = 211
Subtract 91 from both sides.
2b = 120
Divide both sides by 2.
b = 60
Answer:
13v + 2b = 211
4v + 4b = 268
#students each VAN can carry: 7
#students each BUS can carry: 60

so angle PSQ=25°
Answer:

If it is a parallelogram, then the sides PS and QR will be parallel, then ∠PSQ and ∠RQS are alternate interior angles, and hence they will be congruent. That is, ∠PSQ ≅ ∠RQS = 25°.
But this is not the confirmation that this would be parallelogram as it could be trapezoid. The given condition is must but not sufficient to prove it.

1.5,3,4.5,6,...arithmetic sequence or geometric sequence
Answer:
Step-by-step explanation:
1.5 , 3 , 4.5 , 6 ............
This is an arithmetic sequence. Each term is obtained by adding 1.5 to the previous term.
First term = 1.5
Common difference = second term - first term
= 3 - 1.5 = 1.5
Check:
Second term = 1.5 + 15 = 3
Third term = 3 + 1.5 = 4.5
Fourth term = 4.5 + 1.5 = 6
sec 5A = cosec 7A, prove that A = 7.5°
Answer:
see explanation
Step-by-step explanation:
Using the cofunction identity
sec(90 - x)° = cscx° , then
7A = 90 - 5A ( add 5A to both sides )
12A = 90° ( divide both sides by 12 )
A = 7.5°
