which integer is the smallest?
A: 0
B: 29
C: -30
D: -1
Answer:
-30
Step-by-step explanation:
0 is greater the -30 and -1 but less then 29
29 is greater then 0, -30, and -1
-1 is less the 0 and 29 but greater then -30
-30 is less then 0, 29, and -1
from greatest to smallest
29, 0, -1, -30
-30 is the smallest integer
Replacing the maximum value of the data set with a smaller number will also affect the mean. A:always B:sometimes C:never
Answer:
B: sometimes
Step-by-step explanation:
Let's look at two examples.
Example A.
2, 3, 5: mean is 3
Replace 5 with 1. Now you have 1, 2, 3: mean is 2.
In this case, it affected the mean.
Example B.
2, 3, 5: mean is 3
Replace 5 with 4. Now you have 2, 3, 4: mean is 3.
In this case, it did not affect the mean.
As you can see, replacing the maximum value of the data set with a smaller number may or may not change the mean.
Answer: B: sometimes
PLEASE ANSWER
During a flu epidemic the number of sick people triples every week what is the growth rate as a percent ?
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

Amelia rented a dvd and it was due to be returned on 26 november
she actually returned it to the shop on 26 december
the rental shop applies a fine for 9p for every day the dvd is overdue
work out the total fine paid by amelia
give your answer in £?
Step-by-step explanation:
9p*30days= 45p
45÷100=0.45£
The correct answer would be No fine is paid if the DVD is returned by the due date, because the first 0 means it is 0 days overdue, so it is returned on time, and the second 0 means the fine would be $0!!

becasue i hungryConsider 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
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%

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?
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°

two 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.
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
