If women always married men who were 2 years older
than themselves, what would the correlation between the ages
of husband and wife be?
(a) 2
(b) 1
(c) 0.5
(d) 0
(e) Can't tell without seeing the data
Answer:
If you were to create a scatterplot using sample ages such as : (30,32),(33,35),(47,49), etc. You will begin to see a perfect linear relationship, which would mean the correct correlation is 1.

Question 8 measurements. Angle H (acute) Angle M (obtuse) Angle K (acute)
Question 9 measurements. Angle P (right) Angle Q (obtuse) Angle R (acute) Angle S (obtuse) Angle T (right)
Any angle that is visibly smaller than 90° in shape is an acute angle.
Any angle that has a square denoted inside the angle means that it is a 90° angle, therefore implying that it is a right angle.
Any angle that is visibly bigger than 90° in shape is an obtuse angle.
Note that in the Q.8, the total summation of the interior angles for a triangle is 180°. In this case, ∠H & ∠K can be safely assumed to be smaller than right angles, which means that ∠M would be either a right angle or obtuse. However, it is not given that ∠M is a right angle, and so the answer is obtuse.
a. Angle H: acute angle
b. Angle M: obtuse angle
c. Angle K: acute angle
It is given that angles P & T are right angles (as denoted by the squares). Therefore, angle Q & S are obtuse, and angle R is acute, based on visible differences:
a. angle P: Right angle.
b. angle Q: Obtuse angle.
c. angle R: Acute angle.
d. angle S: Obtuse angle.
e. angle T: Right angle.
Usually you will not be using visibility to solve the angle measurements, but in this case, it is not stated that shapes are not drawn to scale. Therefore, you can safely assume based on what the angles look like to answer.
A mineral's density is 5g/cm and its volume is 2cm. What is the mass?

If [tex]Distance= \frac{Mass}{Volume}[/tex]
Then
Mass = Density x Volume
NEED HELP ASAP!! ILL GIVE BRAINLIEST IF YOU GET IT RIGHT!!
Explanation:
*Based on what i know / understand*
Well one thing is that it is not E (the last choice because the mean is not the same as the median, they are different, the mean is 10.4 while the median is 13.4
And it can not be C or D because the mean is less than the median. So it is rather A or B.
But I think it is B.

the price of a shirt was reduced $15 to 9$ by what percentage was the price of the shirt reduced
If the price of the shirt was reduced from $15 to $9, the percentage reduction in price is 40%
How to find percentage reduction?
The price of the shirt was reduced from 15 dollars to 9 dollars. Therefore, the percentage reduction can be found as follows:
15 - 9 = 6 dollars
Therefore,
percentage reduction = 6 / 15 ×100
percentage reduction= 600 / 15
percentage reduction = 40%
Therefore, the percentage reduction in price is 40%.

If a cot α = 1 and b cos α = 1, find a2 – b 2
The equivalent expression of the different of two square is -1
Given the following expressions
a cot α = 1
a = 1/cot α = sinα/cosα
b = 1/cos α
We are to find the expression a² - b²
According to difference of two squares;
a² - b² = (a + b) (a - b)
Substitute the given expressions into the formula as shown:
[tex]a^2 - b^2 = (\frac{sin \alpha}{cos \alpha} )^2 - (\frac{1}{cos \alpha} )^2\\a^2 - b^2=\frac{sin^2 \alpha}{cos^2 \alpha} -\frac{1}{cos ^2 \alpha}\\a^2 - b^2=\frac{sin^2 \alpha-1}{cos^2\alpha}\\a^2 - b^2=\frac{-(1-sin^2\alpha)}{cos^2\alpha} \\a^2 - b^2=\frac{-os^2 \alpha}{cos^2 \alpha}\\a^2 - b^2 = -1[/tex]
This shows that the equivalent expression of the difference of two squares is -1

Write the equation of the line shown in the graph to the right
Hint: Think about slope and y-intercept.
Answer:
y=2x-6
Step-by-step explanation:
The intercept is -6 so -6 and you take two points on the line e. g. (3,0) and (2,-2) You would do -2-0 to get -2 and 2-3 to get -1. -2 divided by -1 equals 2. The slope is two.
Determine whether the graphs of the given equations are parallel, perpendicular, or neither.

A number is first increased by 20 and then doubled. The result is 2 less than 5 times the number
set up an equation:
2(x+20) = 5x - 2
Simplify:
2x +40 = 5x - 2
Add 2 to both sides:
2x + 42 = 5x
Subtract 2x from both sides:
42 = 3x
Divide both sides by 3:
x = 42/3 = 14
The number is 14
Answer:
The answer is 14

Answer:
x ≈ - 0.14
Step-by-step explanation:
6(4x + 5) = 3(x + 8) + 3 ← distribute parenthesis on both sides
24x + 30 = 3x + 24 + 3 , simplify
24x + 30 = 3x + 27 ( subtract 3x from both sides )
21x + 30 = 27 ( subtract 30 from both sides )
21x = - 3 ( divide both sides by 21 )
x = [tex]\frac{-3}{21}[/tex] = - [tex]\frac{1}{7}[/tex] ≈ - 0.14 ( to the nearest hundredth )
