Answer:
362 kilometre
Step-by-step explanation:
Let a be the total cost of a journey
let b represent the total distance of a journey
$1.75 is a fixed charge of a journey
the additional charge is $0.10 for b distance ,hence total of additional charge is $.10 multiplied by b i.e 0.1 b
a=1.75+0.1b
a =37.90
37.90=1.75+0.1b
0.1b=37.90-1.75
0.1 b=36.15
b=36.15
/0.10
b=361.5
b=362 kilometre
For the journey that cost 21.80
21.80=1.75+0.1 b
0.1 b=21.80-1.75
0.1 b=20.05
b=20.05
/0.1
b=200.5
b =201 kilometre
Answer:
a. Single-sample Z-Test
b. Single-sample t-test
c. Independent-measures t-test
d. Repeated-measures t-test (Paired-samples t-test)
e. Independent-measures ANOVA
Answer: Option a.
Step-by-step explanation:
It is important to remember the "Product of powers property", which states that:
Then, given the expression , you need to apply the Multiplication property of equality, which states that:
Therefore:
- Multiply both sides of the equation by "a":
- Multiply both sides of the equation by "4". Then you get:
This matches with the option a.
Answer:
To file out an income tax form an individual is eligible to use a 1040EZ form when filling an income tax return which have following features:

<h3>Given</h3>
... r + 7 = 9
<h3>Find</h3>
... r
<h3>Solution</h3>
Subtract 7 from both sides of the equation.
... r + 7 - 7 = 9 - 7
... r = 2 . . . . . . simplify
Expressed as a solution set, this may look like ...
... r ∈ {2}
_____
You probably had no trouble solving this in 2nd grade when it was shown to you in the form ...
__ + 7 = 9
