Answer:
6% growth
Step-by-step explanation:
The equation =
A = 2300(1.06)⁷
What does 0.06 represent in the equation?
The formula for Exponential growth =
y = a (1 +r)^t
Where
y = Size after time t
a = Initial size
r = Growth rate in Percentage
t = Time t
Equating both Equations together
y = a (1 +r)^t = A = 2300(1.06)⁷
1 + r = 1.06
r = 1.06 - 1
r = 0.06
Converting to percent
r = 0.06 × 100
r = 6% growth rate

A textbook company states that the average time a student needs to take a quiz from its book is 30 minutes with a standard deviation of 3 minutes. A teacher using the book is not sure that this is correct for her classes and wants to check. She collects data on 10 random students and finds that the average time to take the quiz was only 25 minutes. As a result, the teacher performs a two-tailed hypothesis test with a significance level of 5%. Which conclusion is valid based on the results of the test
Answer:
We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.
Step-by-step explanation:
We are given;
Population mean; μ = 30 minutes
Population standard deviation; σ = 3 minutes
Sample size; n = 10
Sample mean; x¯ = 25
Significance level = 5% = 0.05
Let's define the hypotheses;
Null hypothesis; H0: μ = 30
Alternative hypothesis: Ha: μ ≠ 30
Let's find the test statistic;
z = (x¯ - μ)/(σ/√n)
z = (25 - 30)/(3/√10)
z = -5.27
From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;
p < 0.00001
This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
Answer:
A. Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
What is the value of the function
g(t) = 2(t-3)-4 for the input value t= 6?
Answer:
2
Step-by-step explanation:
Replace t with 6:
g(t) = 2(t-3)-4 becomes g(6) = 2(6-3)-4 = 2(3) - 4 = 6 - 4 = 2

The dollar value v(t) of a certain car model that is t years old is given by the following exponential function.
v (c) = 20,000(0.88)
Find the initial value of the car and the value after 11 years.
Round your answers to the nearest dollar as necessary.
Initial value:
Value after 11 years:
9514 1404 393
Answer:
initial value: $20,000after 11 years: $4,902Step-by-step explanation:
Assuming your equation is ...
v(t) = 20,000(0.88^t)
The value for t=0 is 20,000.
The value for t=11 is 20,000(0.88^11) ≈ 4,902.
The initial value is $20,000; the value after 11 years is $4,902.

Use your answer from Part I to find the slope of a line going through each set of points. Then
describe the line as positive, negative, zero, or undefined. Show your work and explain your
answer.
A. (5, 7) and (-4,-2)
B. (1, 3) and (1, -10)
Answer:
Step-by-step explanation:
to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.
A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)
B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis

● The short and long hands of a clock are 4 cm and 6 cm long respectively. Find the sum of distance travelled by their tips in 2 days.
Class - 10th
No spam ❌
Juniors stay away ~
Step by step explanation please
Step-by-step explanation:
short hand radius = 4
distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)
distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2
long hand radius= 6
each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution
distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7
distance in 48hr = 37.7 x 48= 1809.6 (approx)
so sum of both= 1809.6 + 50.2 = 1859.8
Answer:
1910.12 cm
Step-by-step explanation:
2 days = 48 hrs = 2880 mins
One cycle of the short hand (4 cm) would be 12 hrs.
48/12 = 4 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 4 cm
2*pi*4 ≈ 25.13 cm (I only rounded to the hundredth, adjust as u need)
25.13 * 4 = 100.52 cm
One cycle of the long hand (6 cm) would be 60 mins (which is 1hr and two days would be 48hrs or 48 cycles. But let's keep this consistent).
2880/60 = 48 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 6 cm
2*pi*6 ≈ 37.70 cm (I only rounded to the hundredth, adjust as u need)
37.70 * 48 = 1809.6
100.52 + 1809.6 = 1910.12 cm

Se tienen dos libros: uno de 240 página y otro de 160 páginas. Si los 2 libros están formados por cuadernillos con el mismo número de páginas (entre 16 y 28), ¿cuántos cuadernillos tienen en total los dos libros?
Answer:
Book of 240 pages has 12 booklets in total
Book of 160 pages has 8 booklets in total.
Total booklets both the books have in total = 20
Step-by-step explanation:
Given - There are two books: one of 240 pages and the other of 160 pages. If the 2 books are made up of booklets with the same number of pages (between 16 and 28),
To find - How many booklets do the two books have in total?
Proof -
Given that, Number of pages of a booklet is between 16 and 28.
So, The number that lies between 16 and 28 will have to divide the number of pages of both the books.
(Because given that both the books are made up of booklet with the same number of pages)
By inspection, we get
The number of pages of a booklet = 20
because
240/20 = 12 and 160/20 = 8
∴ we get
1 booklet = 20 pages
i.e.
20 pages = 1 booklet
⇒1 page = [tex]\frac{1}{20}booklet[/tex]
⇒240 pages = [tex]\frac{240}{20}booklet[/tex] = 12 booklet
So, we get
The book of 240 pages has 12 booklets in it.
Now,
1 page = [tex]\frac{1}{20}booklet[/tex]
⇒160 pages = [tex]\frac{160}{20}booklet[/tex] = 8 booklet
So, we get
The book of 160 pages has 8 booklets in it.
∴ we get
Book of 240 pages has 12 booklets in total
Book of 160 pages has 8 booklets in total.
So, Total booklets both the books have = 12 + 8 = 20

Which of the following is the solution (x,y) of the system of equations x-2y = 2 and -x+2y = 2
Answer:
Step-by-step explanation:
x-2y = 2
-x+2y = 2
set 1st eq. equal to 2nd equation since they both equal 2
x -2y = -x + 2y
2x = 4y
x = 2y
1/2x = y

PLS HELP ME!!!!! Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell. Suppose M is the amount of money the students collect for selling R raffle tickets. Write an equation that reflects the relationship between M and R.
Answer: M=2.4R
Step-by-step explanation:
If 24 dollars are collected for every 10 tickets we can find the cost of each ticket like so...
24/10=2.4
so now we can set up our equation...
M=2.4R
this means we get M amount of money for R number of tickets sold at a rate of $2.40 each.
