To study the effects of a medication on migraines, every 10th adult from an alphabetized list of patients who suffer from migraines were selected. Then, the sample was surveyed about the number of migraines they have each month. The names of the 50 adults selected were written on equal sized tiles, placed in a bag, and mixed well. The people with names on the first 25 tiles selected were given the migraine medication. The remaining 25 people were given a placebo. After six months, all patients were surveyed again about the number of migraines they had each month. The change in the mean number of migraines between the two groups was compared.

A country in South America exported 62% of the 315,000 bags of coffee beans they produced in a given year. How many bags did they export? Can someone please help me without a link to go to.
Answer:
195,300
Step-by-step explanation:
62 percent *315000 =
(62:100)*315000 =
(62*315000):100 =
19530000:100 = 195300
Now we have: 62 percent of 315000 = 195300
Question: What is 62 percent of 315000?
Percentage solution with steps:
Step 1: Our output value is 315000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,315000=100%.
Step 4: Similarly, x=62%.
Step 5: This results in a pair of simple equations:
315000=100%(1).
x=62%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
315000/x = 100/62%
Step 7: Again, the reciprocal of both sides gives
x/315000 = 62/100
x=195300
Therefore, 62% of 315000 is 195300

Answer:
We will use a Pythagorean identity and alegbra to prove this.
sin^2 + cos^2 = 1, dividing by cos^2 gives
tan^2 + 1 = sec^2.
Now, breaking down the fraction into parts and simplifying gives:
(1-sin^4)/cos^4 = 1/cos^4 - sin^4/cos^4 = sec^4 - tan^4
Now use difference of squares factoring from alegbra.
= (sec^2 + tan^2)*(sec^2 - tan^2)
By rewriting our Pythagorean identity to
sec^2 - tan^2 = 1 and tan^2 = sec^2 - 1,
we can finish the problem.
= (sec^2 + tan^2) * 1 = sec^2 + tan^2
= sec^2 + (sec^2 - 1) = 2*sec^2 - 1.

Why we often leave radicals as roots without calculating them?
Answer:
Sometimes it's better to leave them as roots because it's easier sometimes to solve problems with them still as roots
Answer:
We choose to leave radicals as roots without calculating them because calculating the square roots of a non perfect squares result in an irrational, non terminating decimal.
Step-by-step explanation:
Why do we do Radicals in the first place?
Radicals are used to write the square root or the nth root of a number. We sometimes leave specific numbers (non-perfect squares) as a radical because the output would be infinity
Example:
[tex]\sqrt45[/tex] is not a perfect square, it lies between [tex]\sqrt36[/tex] and [tex]\sqrt49[/tex]
This means the number lies in between 6 and 7
The true root of 45 is irrational. Recall that irrational numbers are numbers of non-perfect squares. [tex]\sqrt45[/tex] = 6.7082039.......
Simplify:
[tex]\sqrt 45 = \sqrt 9 * \sqrt 5\\[/tex]
[tex]= \sqrt3^2 * \sqrt 5\\\\ \\= 3\sqrt5[/tex]
We choose not to pursue simplifying this because [tex]\sqrt5[/tex] is irrational (square root of a non-perfect square)
Summary:
We choose to leave radicals as roots without calculating them because calculating the square roots of a non perfect squares result in an irrational, non terminating decimal.

The product of two consecutive even integers is 6 more than 3 times their sum. The integers are: a. 6,8 b. 16, 20 12, 16 d. 20, 24 C.
Answer:
a. 6,8
Step-by-step explanation:
The only offered answer choice that lists consecutive even integers is ...
a. 6,8
_____
Consecutive even integers differ by 2, not 4.

Check
The product is 6×8 = 48.
Three times the sum is 3(6+8) = 3(14) = 42.
The product is 6 more than 3 times the sum. 42+6 = 48

If AB = 7x - 24 and BC = 6x - 2, what is the value of AC?
a. 13x - 22
C. 13x - 26
b. 33
d. 46
Work Shown:
AC = AB + BC
AC = (7x-24) + (6x - 2)
AC = (7x+6x) + (-24-2)
AC = 13x - 26
This works because segment AC is split up into two parts AB and BC which don't overlap. Refer to the segment addition postulate.

Lines r and s are perpendicular and intersect at point k ray kt is drawn forming angles 1 and 2 if angle 1 is 4x-12 and angle 2 equals 3x -8 what is angle 1 to nearest 10th
The measure of angle 1 to the nearest tenth is 50.9 degrees
Since the line r and s are perpendicular, hence the sum of the angle m<RKT and m<SKT is 90 degrees.
Given the following parameters
m<RKT = m<1 = 4x - 12
m<SKT = m<2 = 3x - 8
Taking the sum of the angle and equating it to 90degrees, hence;
m<RKT +m<SKT = 90
4x - 12 + 3x - 8 = 90
7x = 90 + 20
7x = 110
x = 110/7
x = 15.71
Get the measure of angle 1
m<1 = 4x - 12
m<1 = 4(15.71) - 12
m<1 = 50.9 degrees
Hence the measure of angle 1 to the nearest tenth is 50.9 degrees

Solve for L:
P=2L+2W
Answer:
[tex]L=\frac{1}{2}P-W[/tex]
Step-by-step explanation:
Let's solve for L.
[tex]P=2L+2W[/tex]
Step 1: Flip the equation.
[tex]2L+2W=P[/tex]
Step 2: Add [tex]-2W[/tex] to both sides.
[tex]2L+2W+-2W=P+-2W[/tex]
[tex]2L=P-2W[/tex]
