A. The range of the function y = 3x - 2, considering the domain {-1, 2,4}, is given as follows:
Range: {-5, 4, 10}.
B. The set of ordered pairs that represent the function is given as follows:
{(-1,-5), (2,4), (4,10)}
How to obtain the range of the function?The function for this problem is given as follows:
y = 3x - 2.
The domain of the function is given as follows:
{-1, 2,4}.
The range of the function is composed by the numeric values of the function assumed for these input values.
The numeric values of the function are found replacing the lone instance of x by their input values, as follows:
y = 3(-1) - 2 = -5.y = 3(2) - 2 = 4.y = 3(4) - 2 = 10.Hence the range is the set composed by -5, 4 and 10.
An ordered pair has the following format:
(x,y).
In which y is the numeric value of the input x.

If a shirt selling for $18 is marked upto $20 then the % increase is
equal to
a. 11%
b. 10%
c. 12%
d. 9%
Answers
Answer:
11%
Step-by-step explanation:
it is a simple question, whenever you need to find % increase or % decrease.
always divide the increase as in this case $2 by the original amount which is $18 and multiply it by 100 as you need to take the %.
so,
2/18*100 gives you 11.11% * is multiply
Step-by-step explanation:
$20 - $18 = $2
to get % of increase we need to know what % of $18 the $2 are.
$2 ÷ $18 = 0.11111111........
Multiply this number by 100 and you will get the percentage.
0.111111111111........ x 100 = 11.1111111111....%

x = t^3 Take the cube root of both sides
[tex]\sqrt[3]{x} = \sqrt[3]{t^3}[/tex]
[tex]\sqrt[3]{x}=t[/tex] Now square both sides
[tex](\sqrt[3]{x})^2 = t^2[/tex]

The graph which illustrates a proportional relationship is graph c because as the value on the Y-axis increases, the values on the X-axis increases consequently.

Find the value of the test statistic. Round your answer to three decimal places.
Answers
Answer:
The value of the test statistic is 0.4.
Step-by-step explanation:
The value of the test statistic is given by:
Our test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is expected mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Using traditional methods, it takes 8.1 hours to receive a basic flying license.
This means that [tex]\mu = 8.1[/tex]
A researcher used the technique with 23 students and observed that they had a mean of 8.2 hours with a standard deviation of 1.2.
This means that [tex]n = 23, X = 8.2, \sigma = 1.2[/tex]
Find the value of the test statistic.
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \frac{8.2 - 8.1}{\frac{1.2}{\sqrt{23}}}[/tex]
[tex]t = 0.4[/tex]
The value of the test statistic is 0.4.

A number that adds with 2/3 substrate 1/3 will be 8.What should be the number??
Answers
Answer:
The number is [tex]\frac{23}{3}[/tex]
Step-by-step explanation:
I am going to call the number x.
A number that adds with 2/3 subtract will 1/3 will be 8.
As an equation, this is:
[tex]x + \frac{2}{3} - \frac{1}{3} = 8[/tex]
Now we solve the equation to find x. So
[tex]x + \frac{2-1}{3} = 8[/tex]
[tex]x + \frac{1}{3} = 8[/tex]
[tex]x = 8 - \frac{1}{3}[/tex]
[tex]x = \frac{24}{3} - \frac{1}{3}[/tex]
