Variables A and B have a linear relationship with a correlation coefficient of 0.35.
Which statement best analyzes the fit?
1. There is a weak positive correlation.
2. There is a strong negative correlation.
3. There is a strong positive correlation.
4. There is a weak negative correlation.
Answer:
1. There is a weak positive correlation.
Step-by-step explanation:
The correlation coefficient shows the relation of points in a data set. It is between 0 and 1 or 0 and -1. If the coefficient is closer to 0 then the correlation is weak. So, since 0.35 is closer to 0 than 1 it must be a weak correlation. Additionally, because it is positive the correlation must also be positive. A positive correlation means that the line of best fit will have a positive slope.
Logan bought stocks and later sold them for $3,437,500, making a profit of 25%. How much did he pay for the stocks?
Answer:
Logan bought the stocks at $2,750,000
Step-by-step explanation:
So according to the question $3,437,500 is the amount at which 25% interest was made
This means that the original value(100% value) has been increased to 125%(thus 100+25%)
By using ratio and proportion,
If 125%-$3437500
then 100% ={100%/125%}×$3,437,50
=$2,750,000

Find the absolute maximum and absolute minimum values, if any, of the function. (If an answer does not exist, enter DNE.)f(x) = x2 − x − 5 on [0, 5]
Answer:
The absolute minimum value is "[tex]-\frac{21}{4}[/tex]" and the absolute maximum value is "[tex]15[/tex]".
Step-by-step explanation:
Given:
[tex]f(x)=x^2-x-5[/tex]
on,
[tex][0,5][/tex]
By differentiating it, we get
⇒ [tex]f'(x)=2x-1[/tex]
Set [tex]f'(x)=0[/tex]
then,
⇒ [tex]2x-1=0[/tex]
[tex]2x=1[/tex]
[tex]x=\frac{1}{2}[/tex] (Critical point)
When x=0,
⇒ [tex]f(x)=-5[/tex]
When [tex]x=\frac{1}{2}[/tex],
⇒ [tex]f(x)=-\frac{21}{4}[/tex] (Absolute minimum)
When [tex]x=5[/tex]
⇒ [tex]f(x)=15[/tex] (Absolute maximum)
A vacant city lot is being turned into a neighborhood garden. The neighbors want to fence in a triangular section of the lot and plant flowers there. The longest side of the triangle section is 8 feet shorter than twice the shortest side. The third side is 2 feet longer than the shortest side. The perimeter is 58 feet. How long is each side?
Step-by-step explanation:
=>>. Hello mate. (◕ᴗ◕✿)
= Given :-
perimeter of traingle = 58 feet
let the third side be. "X" feet longest side = (2x - 8) feet shorter side = (x + 2) feetPerimeter of traingle = sum of all three sides
=> A/q. ,
( x ) + ( 2x - 8 ) + ( x + 2) = 58. ✓✓✓
x + 2x - 8 + x + 2 = 58
=>. 4x - 6 = 58
=> 4x = 58 + 6
=> 4x = 64
=>. x = 64/4
=|. x = 16 feet
length of third side = 16 feet length of shorter side = 18 feet length of longest side = 24 feet

What is the probability that both cards the player selects are aces?
Answer:
2/52
Step-by-step explanation:
If he took one ace out of 52 cards then it would have been 4/52
but as he's taking 2 aces out of 52 cards it is 2/52
Answer:
[tex]P(AA) =\frac{1}{221}[/tex]
Step-by-step explanation:
Deck contains = 52 cards
Deck contains = 4 Aces
Probability of choosing ace first time
[tex]= \frac{4}{52}[/tex]
Probability of choosing ace again without replacement
[tex]=\frac{3}{51}[/tex]
Probability of 2 aces without replacement

Complete the square to find the y-value for the minimum value of the function-f(x)=x^2-8x+28
9514 1404 393
Answer:
12
Step-by-step explanation:
The square can be completed by adding and subtracting the square of half the linear term's coefficient.
f(x) = x^2 -8x +(-8/2)^2 +28 -(-8/2)^2
f(x) = (x^2 -8x +16) +(28 -16)
f(x) = (x -4)^2 +12
The minimum value of the function is 12, when the squared term is zero.

The term that best describes the point V is (d) the centroid.
What is centroid?The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians. The median is a line that joins the midpoint of a side and the opposite vertex of the triangle.
here, we have,
to determine the point V:
From the figure, we can see that:
The three lines drawn from point V divide the sides of the triangles into equal segments.
Also, the lines from point V are perpendicular to the sides.
The above description represents the definition of a centroid
Hence, the term that best describes the point V is (d) the centroid

A certain type of bacteria is growing at an exponential rate that is modeled by the equation y= ae^kt, where t represents the number of hours. There are 100 bacteria initially, and 500 bacteria five hours later.
Answer:
The number of bacteria after t hours is given by: [tex]y(t) = 100e^{0.3219t}[/tex]
Step-by-step explanation:
Amount of bacteria after t hours:
Is given by the following equation:
[tex]y(t) = ae^{kt}[/tex]
In which a is the initial value and k is the constant of growth.
There are 100 bacteria initially
This means that [tex]a = 100[/tex]. So
[tex]y(t) = ae^{kt}[/tex]
[tex]y(t) = 100e^{kt}[/tex]
500 bacteria five hours later.
This means that [tex]y(5) = 500[/tex]. We use this to find k. So
[tex]y(t) = 100e^{kt}[/tex]
[tex]500 = 100e^{5k}[/tex]
[tex]e^{5k} = 5[/tex]
[tex]\ln{e^{5k}} = \ln{5}[/tex]
[tex]5k = \ln{5}[/tex]
[tex]k = \frac{\ln{5}}{5}[/tex]
[tex]k = 0.3219[/tex]
So
[tex]y(t) = 100e^{kt}[/tex]
[tex]y(t) = 100e^{0.3219t}[/tex]
The number of bacteria after t hours is given by: [tex]y(t) = 100e^{0.3219t}[/tex]

Aarti posted a comment on her blog. Each day the number of responses to her comment was 125% of the number she received on the previous day. If there were 64 responses the first day, how many were there on the fourth day?
Answer:
156 were there on the fourth day.
Step-by-step explanation:
125% of the number she received on the previous day
This means that the previous day number is multiplied the 125%/100% = 1.25.
64 responses the first day
This means that the number of responses after x days is given by:
[tex]R(x) = 64(1.25)^x[/tex]
How many were there on the fourth day?
This is R(4). So
[tex]R(4) = 64(1.25)^4 = 156[/tex]
156 were there on the fourth day.
Answer:

According to the Bureau of the Census, the population of the United States in 1990 was approximately 249 million and in 2000, 281 million. Use this information to predict the population for 2012.
Answer:
The prediction for the population in 2012 will be of 324.9 million.
Step-by-step explanation:
Exponential equation for population growth:
Considering that the population growth varies directly with time, it's value after t years is given by:
[tex]P(t) = P(0)e^{kt}[/tex]
In which P(0) is the initial value and k is the growth rate.
The population of the United States in 1990 was approximately 249 million
This means that [tex]P(0) = 249[/tex], so:
[tex]P(t) = P(0)e^{kt}[/tex]
[tex]P(t) = 249e^{kt}[/tex]
In 2000, 281 million.
2000 - 1990 = 10, so [tex]P(10) = 281[/tex]. We use this to find k.
[tex]P(t) = 249e^{kt}[/tex]
[tex]281 = 249e^{10k}[/tex]
[tex]e^{10k} = \frac{281}{249}[/tex]
[tex]\ln{e^{10k}} = \ln{\frac{281}{249}}[/tex]
[tex]10k = \ln{\frac{281}{249}}[/tex]
[tex]k = \frac{\ln{\frac{281}{249}}}{10}[/tex]
[tex]k = 0.0121[/tex]
So
[tex]P(t) = 249e^{0.0121t}[/tex]
Use this information to predict the population for 2012.
2012 - 1990 = 22, so this is P(22).
[tex]P(22) = 249e^{0.0121*22} = 324.9[/tex]
The prediction for the population in 2012 will be of 324.9 million.
