A researcher is trying to determine the January temperature in regions of the United States using the degrees of latitude. After collecting data, she creates a scatterplot. Given the relationship the researcher is trying to predict, the latitude is the dependent variable and the temperature is the independent variable.True / False.
Solution 1
Answer:
False.
Researcher has taken the temperature as independent variable and latitude as the dependent variable which is wrong. Temperature depends on latitude. So it should be taken as dependent variable and the latitude as independent variable.

Let x = the number
Identify the word problem of the inequality.
Two fifths of one less than a number
= 2/5 (x-1)
Three fifths of one more than that number
= 3/5 (x+1)
Solve the inequality
2/5 (x-1) < 3/5 (x+1)
2x/5 - 2/5 < 3x/5 +3/5
-2/5 -3/5 < 3x/5 - 2x/5
-1< x/5
-5 < x
or
x > -5
The final solution set is B. x > -5

In Korey’s business plan, this information should be included in the 'organizational plan' component.
Step-by-step explanation:
Scenario:
As Korey is planning to
- open a comic book store.
- When the store opens, he plans to be the only employee.
- As the business grows, he will extend his hours of operations and hire additional employees as necessary.
In Korey’s business plan, this information should be included in the 'organizational plan' component.
- An Organizational Plan is generally a “to do” list for any certain organization.
- An Organizational Plan lists out the plan of a certain program or work, and organizational growth spanning a period of time - 6 months, a year, two or five.
- The tasks involved, who is going to be responsible for them, and at what time they would be completed or done.
Therefore, based on the scenario of Korey as mentioned above, in his business plan, this information should be included in the 'organizational plan' component.

Step-by-step explanation:
The total distance to be covered in the race is 1200 meters.
Distance = speed × time
The arrogant hare decides to let the tortoise have a 580-meter head start. The tortoise begins crawling at a constant speed of 5 meters per second when the start gun is fired.
If t represents the number of seconds since the start of the race, then the distance covered by the tortoise is 580 + 5t
Therefore, the function f, used to represent the tortoise's distance from the finish line (in meters) would be
f(t) = 1200 - (580 + 5t)
f(t) = 1200 - 580 - 5t
f(t) = 620 - 5t
For f(t) = 0,
620 - 5t = 0
5t = 620
t = 125 seconds
When the start gun is fired the hare begins running at a constant speed of 9 meters per second. The function g to represent the hare's distance from the finish line (in meters) in terms of the number of seconds t since the start of the race would be
g(t) = 1200 - 9t
If g(t) = 0, then
1200 - 9t = 0
9t = 1200
t = 1200/9 = 133.33 seconds
The tortoise won the race.
Absolute value of -4-√2i = -4-i√2, comparing x = -4, y= -√2
Absolute value = √( (-4)² + (-√2)²),
(-4)² = (-4)*(-4) = 16, (-√2)² = -√2 * -√2 = 2
= √( (-4)² + (-√2)²)
= √(16 + 4) = √20
√20 = √(4*5) = √4 * √5 = 2√5
Absolute value = 2√5
Answer:
The correct answers to the question are
1. Did the coin land on heads?
2. Is the value on the die odd?
3. Is the value on the die more than 3?
4. Does the value on die equal 1, 2, 5, or 6?
Step-by-step explanation:
A dichotomous question is one that has only two possible responses or answers such as Yes or No, Agree or Disagree. Dichotomous question are used to obtain distinctively clear responses in a survey. It limits respondents by providing them with the available choices to choose from
A variable is said to be dichotomous if it has only one two states or categories, for example either male or female or for a coin, either head or tail
State Space
In mathematics a state space is a model of a system related to both the inputs and the outputs of the system
Solution
As such the dichotomous questions to narrow down the entire state space of "flipping a coin and rolling a normal six-sided die" to just 1 outcome are
1. Did the coin land on heads?
2. Is the value on the die odd?
3. Is the value on the die more than 3?
4. Does the value on die equal 1, 2, 5, or 6?
The possible answers to the above questions are yes or no
Possibilities for the coin = heads or tails → possible answers are yes or no
possibilities for the die = 1, 2, 3, 4, 5, or 6
while the possibility of a yes for the die requires as follows
1. Either the die is odd, 1, 3, or 5 or
2 The value of the die is more than 3 which gives 4, 5, or 6
3. Is the value on the die equal 1, 2, 5, or 6
All three questions for the die are required to cover all possible outcomes of 1, 2, 3, 4, 5 and 6 yes or no
Hence there is a possibility to pick the right question to get the same answer for both the coin and the die
Answer:
Step-by-step explanation:
Their original bill was $135.65. If they wanted to leave a 20% tip on the original bill amount, then the amount of tip that they would leave is
20/100 × 135.65 = 0.2 × 135.65 = $27.13
They had a 15% off coupon on meals more than $75. This means that their meal qualified for the coupon. The amount discounted would be
15/100 × 135.65 = 0.15 × 135.65 = 20.3475
The total for the bill with the discount and tip included would be
135.65 - 20.3475 + 27.13 = $142.4325
