Explanation and Check part belowHope this helps :)
Step-by-step explanation:
1. To solve, first isolate the variable by doing the inverse operation which is in this case dividing by - 3 on both sides of the equation.
- 3x < 2
- 3 -3
x < - 1
2. Graph it if needed with an open dot because - 1 is not part of the set of solutions.
<--------○
<----l----l-----l----->
-2 -1 0
Check:
1. Substitute x with any number less than - 1 and solve.
- 3 (- 2) < 2
-6 < 2

a pesticide manufacturer is developing a new type of organic pesticide for a particular plant. to study the effectiveness of the new pesticide, a large sample of young plants is collected. the sample is then separated into many groups of two plants based upon age, size and soil type so that plants with similar characteristics are grouped together. one of the two plants in each group is randomly chosen and administered the pesticide, while both plants are placed in a controlled environment and are exposed to the possibility of attack from the target pests. the plants are inspected regularly over a 3 month period and the results are recorded for comparison.
According to the question, the study is based on the organic pesticide for a particular plant. The pesticide manufacturer is developing a new type of organic pesticide for the particular plants. To understand the application of a new organic pesticide, then perform one experiment where the members of plants have controlled the environment for the testing purpose. In this way, plants can be protected from pest attack. These types of experiments fall under matched pair experiments.
In the matched pair experiments, the samples are divided into two parts. The first part should be based on some controlled characteristics, whereas the other one should be based on randomly assigned characteristics.
What are matched pair experiments.?
Matched pair designs are experimental based designs. In this, one group is protected in a controlled environment whereas the other one is in a random environment.

As the degrees of freedom increase, the t distribution approaches the _____ distribution. a. exponential b. p c. normal d. uniform
As the degrees of freedom (DF) increase, the t distribution approaches the normal distribution. Therefore, the correct answer option is: C. normal distribution.
What is the degrees of freedom (DF)?The degrees of freedom (DF) in a sample are typically used to correct a possible bias that exists between the alternative and null hypotheses because they are the maximum number of logically independent numerical values (data points) in the final calculation of a statistical problem.
What is a normal distribution?A normal distribution is sometimes referred to as the Gaussian distribution and it can be defined as a probability distribution that is continuous and symmetrical on both sides of the mean, which shows that all data near the mean have a higher frequency than data that are far from the mean.
In this context, we can reasonably infer and logically deduce that the t-distribution generally approaches the normal distribution as the degrees of freedom (DF) increase.

No, there is only one outlier at 58 minutes.
What are outliers in data?An observation that differs abnormally from other values in a population-based random sample is referred to as an outlier. In a way, this definition defers to the analyst's (or a consensus process') judgment as to what constitutes aberrant behavior. It is vital to define typical observations before distinguishing aberrant ones.
How do you calculate the outlier?A data point is considered an outlier if it is more than 1.5 times the IQR below the first quartile or more than 1.5 times the IQR above the third quartile, according to the general criterion for utilizing it to compute outliers. The first and third quartile percentiles must be known in order to compute the IQR.

Nate is looking for a repair service for general household maintenance. One
service charges $75 to join the service and $30 per hour. Another service charges
$15 to join the service and $40 per hour. After how many hours of service is the
total cost for the two services the same?
Answer: Total cost for the two services of hours = $6.
Step-by-step explanation:
Given data,
Nate is looking for a repair service for general household maintenance.
First service charges = $75
First service charge per hour = $30 per hour
Another service charges = $15
Another service charge per hour = $40 per hour
Total cost of hours of service is = x
So,
We can write,
75 + 30x = 15 + 40x
Rearrange variables to the left side of the equation,
30x - 40x = 15 - 75
Combine like terms,
-10x = 15 - 75
Calculate the sum or difference,
-10x = -60
Divide both sides of the equation by the coefficient variable,
x = -60/-10
Determine the sign for multiplication or division,
x = 60/10
Cross out the common factor,
x = 6
Therefore,
Total cost for the two services of hours = $6.

Based on the definition of supplementary angles:
x = 5
The measure of angle 6 = 30°
What are Supplementary Angles?If two angles are supplementary, when added together, their sum will equal 180 degrees.
We known that angles 5 and 6 are supplementary angles. Therefore, it means their sum would be equal to 180 degrees.
Hence, we would have the following equation:
m<5 + m<6 = 180
Substitute
40x - 50 + 5x + 5 = 180
Add like terms
45x - 45 = 180
45x = 180 + 45
45x = 225
45x/45 = 225/45
x = 5

consider a little league team that has 13 players on its roster. a. how many ways are there to select 9 players for the starting lineup? b. how many ways are there to select 9 players for the starting lineup and a batting order for the 9 starters? c. suppose 6 of the 13 players are left-handed. how many ways are there to select 3 left-handed outfielders and have all other 6 positions occupied by right-handed players?
There are 715 ways to select 9 players for the starting lineup.
Permutation is used whenever there is arrangement or where order is important . denoted by [tex]P(n,r)=\frac{n!}{(n-r)!}[/tex]
n= no of item , r = no of items to be arranged.
Combination is used when there is selection . denoted by[tex]C(n,r)=\frac{n!}{r!(n-r)!}[/tex]
n=no of item , r= no of item to be selected.
Part (a)
In the given question
we have to select 9 players out of 13 player , combination will be used
[tex]C(13,9)=\frac{13!}{9!*(13-9)!}=\frac{13*12*11*10*9!}{9!*4!} =\frac{13*12*11*10}{4*3*2}[/tex]=715 ways.
Part(b)
In this part we have to find how many ways are there to select 9 players for the starting lineup and a batting order for the 9 starters.
Since the batting order is important , permutation will be used.
[tex]P(13,9)=\frac{13!}{4!} =\frac{13*12*11*10*9*8*7*6*5*4!}{4!} =13*12*11*10*9*8*7*6*5[/tex]
=259459200 ways.
Part(c)
In this part we have to do selection of 3 left-handed outfielders and have all other 6 positions occupied by right-handed players.
Since order is not important Combination will be used.
To select 3 left handers from total 6 left handers = C(6,3)
& to select 6 positions of left handers from remaining 7 right handers=C(7,6)
No of ways of selection = C(6,3)*C(7,6)
[tex]=\frac{6!}{3!*(6-3)!} *\frac{7!}{6!*(7-6)!} \\ \\= \frac{6!}{3!*3!} *\frac{7!}{6!*1!} \\ \\[/tex]
On solving further we get
[tex]= \frac{7!}{3!*3!} =\frac{7*6*5*4*3!}{3!*3*2*1} =7*5*4=140ways[/tex]
Therefore ,(a)There are 715 ways to select 9 players for the starting lineup.

What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , division , etc.
The equation given is [tex]4x^{1/3}[/tex]- x = 0
We need to solve it stepwise.
The first step will be to to move -x to RHS.
[tex]4x^{1/3}[/tex]- x = 0
or
[tex]4x^{1/3}[/tex] = x
The second step is to solve to get the values of x.
4x = x³
4x - x³ = 0
x (4 - x²) = 0
So , this will give us two equations which are ,
x = 0
and
4 - x² = 0
or
x² = 4
x = ± 2
So , solving the equation for x initially yields two equations which are x = 0 and 4 - x² = 0 and the solution we get is x = 0 , 2 , - 2.
Thus , the solutions will be x = -2, 0, 2.
