Consider that a population of fruit flies grew in a 40-day experiment. Average rate of change: 9 flies/day. Find the average growth rate from day 30 to day05
Answers
Answer: Average Growth Rate is 24.19%
Step-by-step explanation:
Given that;
Average rate of change = 9 flies/day
Average growth rate of change = ?
we can determine the average growth rate of change from the expression;
Average Annual Growth Rate = [((Present Value - Past Value)^1/N) - 1 ] × 100%]
Now our present value; 30th day = 9 × 30 = 270
past value; 05th day = 9 × 05 = 45
the value of N = 30 - 5 = 25
so we substitute
Average Annual Growth Rate = [((270 - 45)^1/25) - 1 ] × 100%]
= ([1.2419 - 1) × 100]
= 24.19%
Therefore Average Growth Rate is 24.19%

During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?
Answers
Answer:
2 or 200%
Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week, 6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week

becasue i hungrytwo students have examined the scatter plot shown in have created in line best fit for the data. student A believes that the line of best fit for the data is y= -2x + 24, while student B believes that the line of best fit for the data is y = 1.5 + 23
*Determine which student created a better line of best fit given the data in the graph.
Answers
Answer:
Step-by-step explanation:
im pretty sure its student a not 100% sure tho
The line of best fit is simply the trending line of a graph
Student A creates a better line of best fit
The linear equations are given as:
[tex]\mathbf{y = -2x + 24}[/tex]
[tex]\mathbf{y =1.5x + 23}[/tex]
The given graph shows a negative linear association.
This is so because, as the x-values increases, the y-values decreases.
This in other words means that:
The slope of the graph is negative
A linear graph is represented as:
[tex]\mathbf{y = mx + c}[/tex]
Where: m represents slope
By comparison
m = -2 and m = 1.5 for the equations of the two students.
Because the slope of the graph is negative, then
m =-2 is correct
Hence, student A creates a better line of best fit

There exists a similarity transformation that maps AABC to AA'B'C'. The measure
of ZAis 68°, and the measure of ZBis 46°. What is the measure of ZC'in
degrees?
Answers
Answer:
∠C' = 66°
Step-by-step explanation:
Because triangles ABC and A'B'C' are similar, their angles are still the same; only their side lengths are different, though still proportionate.
Hence, ∠A = ∠A', ∠B = ∠B', and ∠C = ∠C'.
Here, we're given that ∠A = 68, which means ∠A' = 68; we also know that ∠B = 46, so ∠B' = 46.
We want to find C', so remember that all angles in a triangle sum to 180:
∠A' + ∠B' + ∠C' = 180
68 + 46 + ∠C' = 180
114 + ∠C' = 180
∠C' = 66°
Answer:
∠C' = 66°
Step-by-step explanation:
∠A' + ∠B' + ∠C' = 180
68 + 46 + ∠C' = 180
114 + ∠C' = 180
∠C' = 66°

Justin needs to make 80 illustrations for an art book. He has made 40% of the illustrations. How many illustrations does he still need to make?
Answers
We can do this by doing 40 divided by 100 which gives us: 0.40
Therefore 40% in decimal form is 0.40.
Next we do 80 x 0.40 which gives us 32, this means Justin has already made 32 illustrations.
Next we do 80 - 32 which gives us 48, this means Justin still has to do 48 illustrations.
I hope this helps!
32 - 80= 48
