the variables height and weight could reasonably be expected to have a positive linear correlation coefficient, since taller people tend to be heavier, on average than shorter people. Give an example of a pair of variables which you would consider to have a negative linear correlation and explain why. Then give an example of a pair of variables whose linear correlation coefficient is likely to be close to zero
Answer:
i) Speed and travel time
ii) Coffee and car
Step-by-step explanation:
i) Example of a pair of variable that have a negative Linear correlation
A negative correlated pair of variables simply means that the variables are inversely proportional to each other .and an example of such pair of variables is
Speed and Travel Time
Increase in speed causes a decrease in travel time. ( because the faster a car travels the shorter the travel time spent by the car while the slower a car travels the longer the travel time spent by the car )
ii) Example of a pair of variable with no linear correlation ( almost zero )
A close to zero linear correlation shows that there i no actual relationship between the variables.
Coffee and car
Increase or decrease in the cost of coffee will have no significant effect ( either negative or positive ) on the price of cars in the open market.
100 points. You earned $1600 in interest in your savings account over 10 years at a rate of 8%. How much money did you originally deposit into your savings account?
A = p(1+r)^t
1600 = p(1+0.08)¹⁰
P = 1600/2.1589
P= 741.12
741.12 dollar money did you originally deposit into your savings account!
Answer:
Simple interest: Principal = $2000
Annual compound interest: Principal = $1380.59
Step-by-step explanation:
As the question does not stipulate which type of interest was applied, please find below calculations for both simple interest and annual compound interest.
Simple Interest Formula
I = Prt
where:
I = interest accruedP = principalr = interest rate (in decimal form)t = time (in years)Given:
I = $1600r = 8% = 0.08t = 10 yearsSubstitute the given values into the formula and solve for P:
[tex]\implies \sf 1600=P(0.08)(10)[/tex]
[tex]\implies \sf 1600=0.8P[/tex]
[tex]\implies \sf P=\dfrac{1600}{0.8}[/tex]
[tex]\implies \sf P=2000[/tex]
Therefore, the initial deposit (principal) was $2000.
.....................................................................................................
Annual Compound Interest Formula
[tex]\large \text{$ \sf I=P\left[\left(1+r\right)^{t} -1\right]$}[/tex]
where:
I = interest accruedP = principal amountr = interest rate (in decimal form)t = time (in years)Given:
I = $1600r = 8% = 0.08t = 10 yearsSubstitute the given values into the formula and solve for P:
[tex]\implies \sf 1600=P\left[\left(1+0.08)^{10}-1\right][/tex]
[tex]\implies \sf 1600=P\left[\left(1.08)^{10}-1\right][/tex]
[tex]\implies \sf 1600=P\left[2.15892...-1\right][/tex]
[tex]\implies \sf 1600=P\left[1.15892...\right][/tex]
[tex]\implies \sf P=\dfrac{1600}{1.15892...}[/tex]
[tex]\implies \sf P=1380.5897...[/tex]
Therefore, the initial deposit (principal) was $1380.59 (nearest cent).

Answer:
Option (D)
Step-by-step explanation:
Given equation is,
[tex]8e^{2x+1}=4[/tex]
Taking natural log on both the sides of the equation,
[tex]\text{ln}(8e^{2x+1})=\text{ln}(4)[/tex]
[tex]\text{ln}(2^3)+\text{ln}(e^{2x+1})=\text{ln}(2^2)[/tex]
3ln(2) + (2x + 1)[ln(e)] = 2ln(2)
2n(2) - 3ln(2) = (2x + 1)
2x = -ln(2) - 1
[tex]2x=\text{ln}(\frac{1}{2})-1[/tex] [Since, -ln(2) = ln(1) - ln(2) = [tex]\text{ln}(\frac{1}{2})[/tex]]
[tex]2x=\text{ln(0.5)}-1[/tex]
[tex]x=\frac{\text{ln(0.5)-1}}{2}[/tex]
Therefore, Option (D) will be the correct option.

The last day of school is in 3 months. Mrs. Fabrizio's birthday is in 10 weeks. What event does Mrs. Fabrizio have to wait longer for? How much longer? (1 month = 4 weeks)
Answer:
She has to wait longer for the last day of school. She will have to wait 2 more weeks for the last day of school compared to her birthday.
Step-by-step explanation:
If each month is four weeks, this means that 3 months will be 12 weeks. (3×4=12)
Mrs. Fabrizio's birthday is in 10 weeks and the last day of school will be in 12 weeks so she has to wait longer for the last day of school.

GUYS HELP ME There are 6 classes on a field trip . Each class has 28 students and 7 adults going on the field trip they are all traveling by van. Each van holds 9 passengers. What is the fewest number of vans they will need ?
Answer:
24
Step-by-step explanation:
Total number of students and adult per class = 28 + 7 = 35
Van capacity = 9
Number of classes = 6
Total number of students including adults = (35 * 6) = 210
Number of vans needed = total / van capacity
= 210 / 9

Step-by-step explanation:
A farmer wants to plant soy beans and corn. He wants to plant at least 2 acres of soy beans. He has only $1200 to spend and each acre of soy beans costs $200 to plant and each acre of corn costs $100 to plant. Moreover, the farmer has to get the planting done in 12 hours and it takes an hour to plant an acre of soy beans and 2 hours to plant an acre of corn. The farmer profits $500 per acre of soy beans and $300 per acre of corn. If the farmer wants to maximize his profit, how many acres of each should he plant?
9514 1404 393
Answer:
4 acres of each
Step-by-step explanation:
Let s and c represent the number of acres of soybeans and corn, respectively. The problem statement gives rise to several constraints. There is also an objective function to maximize. The linear programming problem can be described by ...
maximize 500s +300c subject to ...
s ≥ 2
200s +100s ≤ 1200 . . . . cost to plant
s + 2c ≤ 12 . . . . . . . . . . . . hours to plant
__
The attached graph shows the objective function is maximized at (s, c) = (4, 4).
The farmer should plant 4 acres each of soybeans and corn.
__
For the solution here, the constraint that s ≥ 2 is irrelevant. If the graph included it, the vertices of the feasible solution space would be (2,5), (4, 4), (6, 0) and (2, 0). The solution that maximizes profit is (4, 4).

Integers are whole numbers that can either be positive, negative, or zero.
Example would be counting numbers
Basically 100-9=91
so there's 91 integers including 9&100
Answer:
92 integers
Step-by-step explanation:
You may think 100-91=9 is correct. But because 9 and 100 are included, you have to add 1 to the answer. However, you don't add 2 since 0 is not included into the integers between 1 and 100.

CRISSY IS BUILDING A RECTANGULAR PRISM WITH
A VOLUME OF 360 CUBIC UNITS. THE HEIGHT OF
THE PRISM IS IO UNITS. CHRISSY CLAIMS THAT THE
BASE OF THE PRISM MUST BE A SQUARE. WHAT
ARE THE DIMENSIONS FOR A RECTANGULAR PRISM
THAT SHOWS CRISSY IS NOT CORRECT?
Answer: Crissy is correct
Step-by-step explanation:
Given
The volume of the rectangular prism is [tex]360\ units^3[/tex]
The height of the prism is [tex]h=10\ units[/tex]
Suppose A is the area of the base
So, the volume is given by
[tex]\Rightarrow V=A\times h[/tex]
Insert the values
[tex]\Rightarrow 360=A\times 10\\\Rightarrow A=36\ \text{or}\ 6\times 6\ units^2[/tex]
As 36 is the perfect square of 6, therefore, the base is a square with the dimension of [tex]6\times 6\ units^2[/tex]
Crissy's claim is correct.
