Answer:
Slope = - 2.5
Step-by-step explanation:
A right angled triangle is drawn to meet the best fit line at any point on the graph,, the point at which the triangle meets the best fit line, provides the values for the rise and run used to calculate the slope, the ris ubsyge cgbage in y values and run is the change in x values ;
Rise, y2 = - 1 ; y2 = 4
Run ; x2 = 3 ; x1 = 1
Rise = y2 - y1 = - 1 - 4 = - 5
Run = x2 - x1 = 3 - 1 = 2
Slope = Rise / Run = - 5 / 2 = - 2.5
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:
125

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

Answer:
The shape from the cross-section resulting from the cut would be a Rhombus
Step-by-step explanation:
Edmentum Plato users!
The shape of the cross-section resulting from the cut is C. Rhombus.
What is a rhombus?A rhombus simply means a shape that has opposite sides to be parallel and the sides are equal.
Here, the information states that the edges of the object in the diagram are equal in length and that the object is cut by a vertical plane containing A and B and bisecting two of the horizontal edges.
Therefore, the shape of the cross-section resulting from the cut is a rhombus.

given a group of six students consisting of four female and two male how many different three member committee can be chosen from this group probability question
Given:
Total number of students = 6
Number of female students = 4
Number of male students = 2
To find:
Total number of outcomes if 3 students are chosen at random (Should i find the probability of something?)
Steps:
To find the total number of outcomes, we need to list the outcomes
Outcomes = {M,M,F} , {M,F,F} , {F,F,F}
Therefore, the total number of outcomes if 3 students are chosen at random is 3, if we don't consider order.

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.
(b) Only one of the sets can contain all five correct answers. If you are guessing, so that you are as likely to choose one sequence of answers as another, what is the probability of getting all five answers correct
Solution :
Given that there is only one set which can contain all the five correct answers. While guessing that I am likely to choose only one sequence of the answers as another, then the probability of getting all the five answers correct is given by :
Given : X [tex]\sim[/tex] binomial [tex]$\left( 5 , \frac{1}{3} \right)$[/tex]
P (X = 5)
[tex]$= \ ^5C_5\left({\frac{1}{3}\right)^5\left(\frac{2}{3}\right)^0$[/tex]

Answer:
17
Step-by-step explanation:
2a+30 = 4a-4
+4 +4
2a+34 = 4a
-2a -2a
34 = 2a
÷2 ÷2
a=17
Hope this helps! :)
Answer:
A = 17
Step-by-step explanation:
Opposite angles are congruent in a parallelogram
Hence 2a + 30 = 4a - 4
( Note that we've just created an equation that we can use to solve for a)
We now solve for a
2a + 30 = 4a - 4
Add 4 to both sides
2a + 34 = 4a
Subtract 2a from both sides
34 = 2a
Divide both sides by 2
a = 17

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)

= 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
