The strength and relationships of the given data is verified as reasonable.
Given,
Determine the degree of the link (weak, moderate, or strong) in each of the six plots and if it is reasonable to fit a linear model to the data.
(a) There is a moderate relationship in the data. A linear model should not be reasonable.
→ From the plot here, it is clear that the data is following a quadratic trend, so a linear model should not be reasonable. On the other hand, it is also clear that the data is scattered more than a little around the approximate quadratic trend line, so there is a moderate relationship in the data.
(b) There is a strong relationship in the data. A linear model should be reasonable.
→ From the plot here, it is clear that the data is following a linear trend, so a linear model should be reasonable. On the other hand, it is also clear that the data is scattered almost a little around the approximate linear trend line, so there is a strong relationship in the data.
(c) There is a weak relationship in the data. A linear model should not be reasonable.
→ From the plot here, it is clear that the data is not following any trend, so a linear model should not be reasonable. On the other hand, it is also clear that the data is scattered everywhere, so there is a weak relationship in the data.
(d) There is a moderate relationship in the data. A linear model should not be reasonable.
→ From the plot here, it is clear that the data is following a quadratic trend, so a linear model should not be reasonable. On the other hand, it is also clear that the data is scattered more than a little around the approximate quadratic trend line, so there is a moderate relationship in the data.
(e) There is a strong relationship in the data. A linear model should be reasonable.

Step-by-step explanation:
A furniture maker uses the specification 17.9≤w≤18.1 for the width w in inches of a desk drawer. Write the specification as an absolute value inequality.
The specification as an absolute value inequality is l w - 18 l ≤ 0.1.
Given:
A furniture maker uses the specification 17.9≤w≤18.1 for the width w in inches of a desk drawer.
m = 17.9 + 18.1 / 2
= 36/2
= 18
t = 18.1 - 17.9
= 0.2/2
= 0.1

Answer:
19%
Step-by-step explanation:
You want the probability a student is a senior, given that they are female.
TableThe table indicates that 3 +4 +6 +3 = 16 students are female. Of those, 3 are seniors. The desired probability is ...
P(senior | female) = N(senior & female)/N(senior) = 3/16 = 0.1875

how much of brand A fruit punch (20% fruit juice) must be mixed with 9 L of brand b fruit punch (40% fruit juice) to create a mixture contains 32% fruit juice ?
6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.
Let x=liters of Brand A fruit punch to be mixed with 9 liters of Brand B fruit punch.
x + 9 = liters of mixture.
20%(x) + 9*40% = 32%(x+9)
20/100 x + 9*40/100 = 32/100 (x+9)
0.2x + 360/100 = 0.32x + 9*0.32
0.2x + 3.6 = 0.32x + 2.88
0.12x = 3.6 - 2.88
0.12x = 0.72
divide by 0.12 on both sides
x = 0.72/0.12
= 72/100/12/100
= 72/12
= 6 liters.
Therefore 6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.

As a general rule;
For a relation to be considered a function, the following must be true:
One x value must not point to several y values
Using the above as a guide, the ordered pair in the relation are not functions
This is because one x value must not point to several y values

What number needs to be added to this set of numbers so the mean is 6? {3,4,7}
The finalized set is { 3 , 4 ,7 , 10 }
How is mean calculated ?Only numerical variables, whether continuous or discrete, can be used to calculate the mean. It is calculated by merely dividing the total number of values in a data set by the sum of all the values in the data set.
The given set is {3,4,7}
3 + 4 + 7 =14
To calculate the mean we divide the sum by the number of numbers present
So we must add 10
because if we add 10 to the set we get
3 + 4 + 7 + 10= 24
Thus the mean = [tex]\frac{24}{4}[/tex]
When we divide these two numbers we get :
mean = 6

The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3 is
The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3, using arithmetic sequences, is of:
122.
What is an arithmetic sequence?An arithmetic sequence is a sequence of values in which the difference between consecutive terms is constant and is called common difference d.
The nth term of an arithmetic sequence is given by the rule presented as follows:
[tex]a_n = a_1 + (n - 1)d[/tex]
In which [tex]a_1[/tex] is the first term of the arithmetic sequence.
The sequence composed by the integer multiples of 11 between 1 and 2022 are given as follows:
(11, 22, ..., 2013)
The first term and the common ratio of the sequence are given as follows:
[tex]a_1 = 11, d = 11[/tex]
The number of terms is obtained as follows:
2013 = 11 + 11(n - 1)
11n = 2013
n = 2013/11
n = 183.
The sequence composed by terms that are multiples of 11 and of 3 is given by:
(33, 66, ..., 2013).
The first term and the common ratio of the sequence are given as follows:
[tex]a_1 = 33, d = 33[/tex]
The number of terms is obtained as follows:
2013 = 33 + 33(n - 1)
33n = 2013
n = 2013/33
n = 61.
Hence the number of integers that are multiples of 11 but not 3 is given by:
183 - 61 = 122.

In the first week of July,1,020 a record people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 175 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
The percent decrease in the number of people who went to the pool over these four weeks is 15.2%.
How to calculate the percentage?The change regarding the people at the swimming pool for the number of weeks will be:
= 1020 - 125 + 145 - 175
= 865
The initial number of people is 1020.
Therefore, the percentage decrease will be:
= Decrease in number / Initial number × 100
= (1020 - 865) / 1020 × 100
= 155/1020 × 100
= 15.2%
The Percentage is 15.2%.

Quotient is 2x³ +x² -4x+3 for (2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)
What is Division?A division is a process of splitting a specific amount into equal parts.
(2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)
Let f(x)=2x⁴ – 3x³ – 6x² + 11x + 8
and g(x)=x-2
We need to divide the f(x) by g(x),
f(x)=g(x)× (2x³ +x² -4x+3)+16
If we equate the above equation with division algorithm which says,
a=bq+r
f(x)=g(x)q(x)+r(x)
so quotient is 2x³ +x² -4x+3
Hence quotient is 2x³ +x² -4x+3 for (2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)
