Answer:
marked angles (K, M): 63°, unmarked angles (L, N): 117°
Step-by-step explanation:
Opposite angles are congruent in a parallelogram.
5x -12° = 3x +18°
2x = 30°
x = 15°
3x +18° = 3(15°) +18° = 63°
Angles K and M are 63°; angles L and N are supplementary, 117°.

How can estimating the quotient help you check that your answer to a division problem is reasonable?
Answers
Explanation:
If your actual answer is very far from your estimate, you probably made a mistake somewhere.

Additional comment
50 years ago, when a slide rule was the only available calculation tool, making an estimate of the result was a required part of doing the calculation. Not only were the first one or two significant digits needed, but also the power of 10 that multiplied them. Use of a slide rule required the order of magnitude be computed separately (by hand) from the significant digits of the result.
__
You may also find it useful to estimate the error in your estimate. That is, you may want to know the approximate answer to 2 (or more) significant digits in order to gain confidence that your calculation is correct.
A Washington Post article reported on a study about alcohol consumption and cancer in women. Since 1996, a team of British researchers has been gathering detailed information from 1.28 million women aged 50 to 64. The researchers recorded how much alcohol the women reported consuming when they volunteered for the study and again three years later. The researchers then examined whether there was any link with the 68775 cancers the women developed over an average of the next seven years. They found that even among women who consumed as little as 10 grams of alcohol a day on average (the equivalent of about one drink), the risk for cancer of the breast, liver, and rectum was elevated.
Required:
a. Is this an experiment? Explain your answer.
b. We would prefer a sample survey to using women who volunteer for a study. What population does it appear that the researchers were interested in?
c. What variables did they measure?
Answers
Part A
This is not an experiment.
Why not? Because the participants aren't divided into two groups of control group vs treatment group. This is an observational survey in which the researchers are asking each participant about the alcohol consumption level (independent variable) and how it may be tied to the risk of cancer (dependent variable).
======================================================
Part B
The population appears to focus on all women between the ages of 50 and 64.
The sample of the 1.28 million women is not the population, but rather, it ideally tries to approximate the population the best it can.
======================================================
Part C
The independent variable is the alcohol consumption rate, i.e. how much beer/wine/etc was consumed. Think of it like the variable x as the input of a function.
The dependent variable is the cancer rate. It's similar to the y output of a function. The dependent variable depends on the independent variable; hence the name. The study is trying to see if altering the amount of alcohol somehow alters the rate of cancer.
Keep in mind that cancer is still a very ongoing subject of research. Unfortunately we still have a lot to learn about it. Despite this, it's highly unlikely that alcohol is the direct cause of cancer. So instead, we consider that these variables are correlated in some way even if a link is found/proven. Other factors need to be considered such as

Answer:

Step-by-step explanation:
The diagonal of a square is √2 times the side length, so the side length is 1/√2 = (√2)/2 times the length of the diagonal:
s = (√2)/2 × 1250 cm = 625√2 cm
The side length is 625√2 cm.

A unit square will have sides of length 1. A diagonal of the square will divide it into two right triangles, each with sides of length 1. The Pythagorean theorem tells you the length of the diagonal (d) will be ...
d² = 1² +1² . . . . . . square of hypotenuse is sum of squares of legs
d² = 2 . . . . . . . simplify
d = √2 . . . . . take square root

How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division is to be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the solution of 234 divided by 6.5
A negative divided by a negative is positive, thus
234 / 6.5 = 2340/65
= 36
Therefore, The value of 234 divided by 6.5 is; 36

- In a public examination, the standard score of Wilson is -3. The scores in the examination are normally distributed and there are 20 000 candidates in the examination. Find the percentage of candidates with scores higher than Wilson.
Answers
Answer:
First of all, 50% of the scores are below the mean (80) and 50% are above (roughly). Approximately 68% of the data are within one standard deviation from the mean - 34% above and 34% below. A score of 87 is one standard deviation above the mean, correct? To answer "What percent scored less than 87?" We already know that 50% scored less than 80. We also know that 34% scored between 80 and 87. So 50% plus 34% is 84%. Let me make a video for this. A visual representation will make this WAY easier to understand.

Answers
The approximate area in square feet of the side panel is 146.4 ft²
What is area:
Area can be defined as the size of a surface. In other words it is defined as the space occupied by a shape.
Therefore, area of a triangle can be described as follows:
area = 1 / 2 bhwhere
b = base
h = height
Using trigonometric ratio, let's find the height of the right angle triangle. Therefore,
sin 30° = opposite / hypotenuse
sin 30° = h / 26
cross multiply
h = 26 × 1 / 2
h = 13 ft
Let's find the base of the triangle using Pythagoras theorem. Therefore,
c² = a² + b²
where
c = hypotenuse
a and b are the other 2 legs.
Therefore,
26² - 13² = b²
b² = 676 - 169
b = √507
b = 22.5166604984 ft
Area of the side panel = 1 / 2 × 22.5166604984 × 13
Area of the side panel = 292.716586479 / 2
Area of the side panel = 146.35829324
Area of the side panel = 146.4 ft²

(d) y = -5/2x -3
Step-by-step explanation:
All of the offered choices are in slope-intercept form, so it makes sense to put the given equation in that form. Solving for y, we get ...
5x +2y = -4
2y = -5x -4 . . . . . subtract 5x
y = -5/2x -2 . . . . . divide by 2
The system of equations will have no solution if the equations are "inconsistent." That will be the case when the slope is the same, but the y-intercepts are different. That means you're looking for an answer of the form ...
y = -5/2x +c . . . . . . where c is not -2
This matches the last choice:
y = -5/2x -3
