D. As one variable decreases, the other increases.
A negative linear association means that as one variable decreases, the other variable increases. This indicates an inverse relationship between the two variables.
As the value of one variable decreases, the value of the other variable tends to increase consistently and vice versa. This pattern can be observed when plotting the data points on a scatter plot, where the points tend to form a downward sloping line.
Option A is incorrect because a negative linear association implies a clear relationship between the variables, unlike no relation. Option B is incorrect because it describes a positive linear association, where both variables increase together.
Option C is incorrect because the presence of both negative and positive numbers does not necessarily indicate a negative linear association. The key characteristic of a negative linear association is the inverse relationship between the variables as described in option D.

what is 12x12-11+14-18=?
Answer:
129
Step-by-step explanation:
First we check for parentheses which there is none.
We would first do 12 x 12=144
Then we would do addition and subtraction left to right.
so just in order.
Second we would do 144 - 11=133
Third we would do 133 + 14=147
And last 147 - 18=129 And there's your answer.

Find the tangent line approximation to 21/x near x = 21.
21/x≈
Answer:
y = -0.05x + 2.05
Step-by-step explanation:
y = 21/x = 21x^-1
y' = -21x^-2 = -21/x^2
At x = 21 slope = -21/(21)^2 = -0.05 to nearest hundredth.
Tangent line is y - 1 = -0.05(x - 21)
y = -0.05x + 1.05 + 1
y = -0.05x + 2.05

We discovered that 650 GSS respondents in 2006 watched television for an average of 2.98 hrs/day, with a standard deviation of 2.4 hours. Answer the following questions, assuming the distribution of the number of television hours is normal. What is the Z score for a person who watches more than 8 hrs/day. 2.09 What proportion of people watch 5 hrs/day or more television? 0.84 How many does this correspond to in the sample? 130 What number of television hours per day corresponds to a Z +1. -0.825 What is the percentage of people who watch between 1 and 6 hours of television per day? Please round to a whole number 1.26
Answer:
a)2.09
b) 0.2
c) 130 correspondents
d) 5.38 hours per day
e) 69%
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where
x is the raw score,
μ is the population mean,
σ is the population standard deviation.
Mean = average of 2.98 hrs/day, Standard deviation = 2.4 hours.
a) What is the Z score for a person who watches more than 8 hrs/day.
z = (x-μ)/σ
= 8 - 2.98/2.4
= 2.09167
≈ 2.09
b) What proportion of people watch 5 hrs/day or more television?
z = (x-μ)/σ
= 5 - 2.98/2.4
= 0.84167
P-value from Z-Table:
P(x<5) = 0.80001
The proportion that watches 5 hrs/day or more television?
P(x>5) = 1 - P(x<5) = 0.19999
≈ 0.2
c) How many does this correspond to in the sample?
From the question we are told:
650 GSS respondents in 2006 watched television for an average of 2.98 hrs/day, with a standard deviation of 2.4 hours.
Hence, the proportion that corresponds to people who watch 5 hrs/day or more television form the samples is
0.2 × 650
= 130 correspondents.
d) What number of television hours per day corresponds to a Z +1.
z = (x-μ)/σ
+1 = x - 2.98/2.4
Cross Multiply
1 × 2.4 = x - 2.98
2.4 = x - 2.98
x = 2.4 + 2.98
x = 5.38 hours per day
e) What is the percentage of people who watch between 1 and 6 hours of television per day?
Step 1
For 1 hour
z = (x-μ)/σ
= 1 - 2.98/2.4
= -0.825
Probability value from Z-Table:
P(x = 1) = 0.20469
Step 2
For 6 hours
z = (x-μ)/σ
= 6 - 2.98/2.4
= 1.25833
Probability value from Z-Table:
P(x = 6) = 0.89586
The percentage of people who watch between 1 and 6 hours of television per day is
P(x = 6) - P(x = 1)
= 0.89586 - 0.20469
= 0.69117
Converting to percentage =
0.69117 × 100
= 69.117 %
Approximately = 69%

Part D How many of the 320 million Americans would you predict wear CORRECTIVE lenses?
Answer:
320,000,000 * 0.638 = 204,160,000
Step-by-step explanation:
Assuming the sample is a good representation of the people from the United States.
Since there were 1,000 surveyed... and 638 of them were wearing glasses, that makes a proportion of 638 out of 1,000 people, or 63,8 / 100 people... so 63.8%... or 0.638
So, if we assume that the US population is of 320 million, how many people does that make wearing glasses.... we just have to multiply 320M by 0.638
the product of number is 1 236 if one factor is 103 what is the other factor?
12 or 10 or 9 or 8?
Answer:
The other factor is 12⇒ A
Step-by-step explanation:
The factors of a number are all the numbers multiplied to form this number
Examples:
The factors of 12 are 1, 2, 3, 4, 6, 12 because
1 × 12 = 12
2 × 6 = 12
3 × 4 = 12
∵ The product of numbers = 1236
∵ One factor of that number is 103
∴ ------ × 103 = 1236
→ Divide the number by its factor to find the other number
∴ 1236 ÷ 103 = -------
∵ 123 ÷ 103 = 1 R 20
∵ 206 ÷ 103 = 2
∴ 1236 ÷ 103 = 12
∴ The other factor is 12
Simplify this complex fraction 2/5 divided by 5/8
Answer:
1 19/21
Step-by-step explanation:
brainliest pls :D
Answer:
0.64
Step-by-step explanation:
Let's think about a few simple examples. Once you understand them, you
will be able to put them together to make harder problems.
Ex: What is 2 divided by 1/5? Here are 2 blocks:
+---------+---------+
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
+---------+---------+
Here is 1/5 of a block (the shaded part):
+---------+
|XXXXXXXXX|
+.........+
| |
+.........+
| |
+.........+
| |
+.........+
| |
+---------+
To divide 2 by 1/5, we divide 2 blocks into pieces the size of the 1/5
block.
+---------+---------+
| | |
+.........+.........+
| | |
+.........+.........+
| | |
+.........+.........+
| | |
+.........+.........+
| | |
+---------+---------+
There are 10 pieces this size in the 2 blocks. In other words,
2 divided by 1/5 = 10
That's the same as
2 x 5 = 10
Do you see why? To make 1/5 size blocks, we had to make each whole
block into 5 pieces. In other words, we multiplied the number of
pieces by 5.
Next problem:
2 divided by 2/5 = ?
Here is 2/5 of a block (the shaded part):
+---------+
|XXXXXXXXX|
+.........+
|XXXXXXXXX|
+.........+
| |
+.........+
| |
+.........+
| |
+---------+
Let's divide the 2 blocks into pieces this size.
+---------+---------+
| | |
+ + +
| | |
+.........+.........+
| | |
+ + +
| | |
+.........+.........+
| |
+---------+---------+
The bottom block is a different shape, but it's the same size, because
it's made of 2 1/5-size pieces. Since the pieces we want are twice as
big, there are only 1/2 as many of them. The answer is
2 divided by 2/5 = 10/2 = 5
This is the same as
2 x 5/2 = 5
Do you see how the two equations are related? You take the fraction,
2/5, and "turn it upside down" (in math words, we say "invert the
fraction," or "take its reciprocal"). Then replace the division sign
by a multiplication sign.
Now we can tackle harder problems. The same method always works, even
if the answer isn't a whole number as in the simple examples. For
instance,
5 divided by 3/8 = ?
Ex: Invert the fraction 3/8; you get 8/3. Then multiply by this fraction:
5 x 8/3 = 40/3 = 13 1/3
We can even replace the whole number in the problem with a fraction,
like this:
5/7 divided by 3/8 = ?
5/7 x 8/3 = ?
5 8 40 19
--- x --- = ---- = 1 ----
7 3 21 21
If you are comfortable with multiplying fractions, then you will have
no trouble dividing fractions. Just remember: invert the fraction you
are dividing by (the divisor), and multiply instead of dividing. Hope this helps! :)

Answer:
m∠R = 56°
Step-by-step explanation:
2(8x - 12) = 16x - 24
2(3x + 5) = 6x + 10
16x + 6x + 10 - 24 = 360
22x - 14 = 360
22x = 374
x = 17
3x + 5 = 17 x 3 = 51 + 5 = 56
