Answers
Answer:
A
Step-by-step explanation:
every term of the sequence is created by multiplying the previous term by -2.4
to get the ratio (or multiplication factor) of the sequence :
4 × r = -9.6
r = -9.6/4 = -2.4
and as you can easily check, the following y values use the same factor.
so, as multiplication is used, it is a geometric sequence.
if addition were used, it would be an arithmetic sequence.
but the differences between the y values are clearly not constant (as it would be, if we added a fixed constant to every term to create the next).
so, B and D are automatically wrong.
and C is wrong, because the given ratio or multiplication factor cannot be right :
4 × 0.4 = 1.6 and never -9.6

What the question is thats how to calculate the median.
Have a wonderful day!
From the definition of the range, we understood that the given statement is false.
The given statement is "The range is calculated by adding the highest and lowest scores in a data set and then dividing by the number of scores in the dataset".
We need to state whether the given statement is true or false.
What is the range?The range formula is mostly used in statistics to determine the range given in a particular data set. The formula helps in determining the centre of the set by finding the difference between the lowest and the highest number. In distribution, the large range means higher variability whereas the small range means low variability. The range formula includes the other aspects of statistics such as mean, median, and mode. Hence, the formula to calculate the range is:
R = Highest Value (H) - Lowest Value (L).
Therefore, from the definition of the range, we understood that the given statement is false.

Step-by-step explanation:
Given
- 6x - 10 > 14 + 2x ( subtract 2x from both sides )
- 8x - 10 > 14 ( add 14 to both sides )
- 8x > 24 ← required missing step

Answers
Step-by-step explanation:
2 cm
scale factor of 3
then 6/3 = 2 cm
Answer:
C. 2 cm
Step-by-step explanation:
As the circumference is a measure of length (one dimension), we can simply divide the given circumference of circle N by the scale factor to find the circumference of circle M:
⇒ circumference of circle M = circumference of circle N ÷ scale factor
= 6 cm ÷ 3
= 2 cm
(If we were working with area, we would have to divide/multiply by the square of the scale factor, since we would be working in 2 dimensions)

2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For
<en place.
the first three hours of typhoon, the rain fell at a constant rate of 25mm per hour.
The typhoon slows down for an hour and started again at a constant rate of 20 mm
per hour for the next two hours. Write a piecewise function that models the amount
of rainfall as function of time.
Answers
Answer:
The piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]
Step-by-step explanation:
Let x be the time in hour and A(x) be the amount of accumulating rainfall at time x.
We are given that in the first three hours the rain fell at a constant rate of 25mm per hour
Amount of rainfall in 1 hour = 25
Amount of rainfall in t hours = 25x
[tex]A(x) = 25x ; 0 \leq x \leq 3[/tex]
The rain then slows down and remains constant
So, Amount of rain for that hour = [tex]25 \times 3 = 75 mm[/tex]
75 mm ; 3
Now we are given that started again at a constant rate of 20 mm per hour for the next two hours.
Amount of rain after 4 hours = [tex]75+20(x-4) ; 4 \leq x\leq 6[/tex]
The rain increases at a rate of 20t from 4 ≤ x ≤ 6.
Hence the piecewise equation is given as :[tex]A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}[/tex]

Answers
The inequality which is used to find the number of cups of yogurt Monica can buy is,
[tex]1.20x+2.5\leq20[/tex]
What is the inequality equation?Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Monica needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. Let suppose the number of cups of yogurt bought by Monica is x.
As she has only $20. Thus, the inequality expression which can be used for this condition is,
[tex]1.20x+2.5\leq20[/tex]
Solve the above equation and find the value of x,
[tex]1.20x\leq20-2.5\\1.20x\leq17.5[/tex]
Divide both side with 1.20,
[tex]x\leq\dfrac{17.5}{1.20}\\x\leq14.58\overline3[/tex]
Hence, the number of cups she can Monica is 14.
Thus, the inequality which is used to find the number of cups of yogurt Monica can buy is,
[tex]1.20x+2.5\leq20[/tex]

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
Y= 30(1.003)^x
Answers
For the given exponential function, the change represents a growth and the percentage rate is 0.3%.
Exponential FunctionThe formula for the exponential function is:
[tex]y(t)=y(0)*(1+R)^t[/tex], where:
y(t)= final value
yo=initial value
R=rate
t= time
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives: [tex]y=30*(1.003)^x[/tex].
When you compare [tex]y=30*(1.003)^x[/tex]with [tex]y(t)=y(0)*(1+R)^t[/tex], it is possible to see:
1. 1+R=1.003, so >1 . Therefore, the change represents growth.
2. 1+R=1.003 , therefore,
1.003=1+R
R=1.003-1
R=0.003
then,
%R=0.003*100=0.3%

Answer:
$646.25 is her earnings when selling $975.
Her earnings when selling $x is 500 + 0.15x.
Step-by-step explanation:
You know that her guaranteed salary is $500, and she also gets a commission that is 15% of her sales. So, the expression is
500 + 0.15x
Where x is total sales. When you are given $975 as her total sales, plug it in for x:
500 + 0.15(975)
500 + 146.25
$646.25 is her earnings when selling $975.
Her earnings when selling $x is 500 + 0.15x.
