Step-by-step explanation:
Simple interest is given by
I = PRT where I is the interest, P is the principle r is the rate and t is time
If we have 249 in the account and started with 200,
the interest is 249-200 = 49
The principle is 200 and the rate is 3.5% or in decimal form .035
Putting into the equation
49 = 200 (.035) t
49 =7t
Divide each side by 7
49/7 = 7t/7
7 =t
It will take 7 years
Answer:
7 years
Step-by-step explanation:
I = P×r×t
I = 249 - 200 = 49
49 = 200 × (3.5/100) × t
t = 49/7
t = 7

Final answer:
The equation formed based on the information that Paul halves the number to get 6 is x/2 = 6. Multiplying both sides by 2 gives us x = 12, which is the original number that Paul was thinking of.
Explanation:
The student question regarding forming an equation from a given word problem can be translated into: Paul halves the number and gets 6. To form an equation with x, we represent the unknown number as x, and then create an equation based on the information given. Since halving the number results in 6, the equation we form is x/2 = 6.
To find the value of x, we can multiply both sides of the equation by 2, which will give us x = 6 × 2. This simplifies to x = 12, which is the original number Paul was thinking of.

A quantity with an initial value of 830 grows exponentially at a rate such that the quantity doubles every 2 weeks. What is the value of the quantity after 21 day, to the nearest hundredth?
Answer:
The value of the quantity after 21 days is 2,347.59.
Step-by-step explanation:
The exponential growth function is
[tex]A=A_0(1+r)^t[/tex]
A= The number of quantity after t days
[tex]A_0[/tex]= initial number of quantity
r= rate of growth
t= time in days.
A quantity with an initial value of 830 grows at a rate such that the quantity doubles in 2 weeks = 14 days.
Now A= (2×830)= 1660
[tex]A_0[/tex] = 830
t = 14 days
r=?
Now plug all value in exponential growth function
[tex]1660=830(1+r)^{14}[/tex]
[tex]\Rightarrow \frac{1660}{830}= (1+r)^{14}[/tex]
[tex]\Rightarrow 2= (1+r)^{14}[/tex]
[tex]\Rightarrow (1+r) ^{14}=2[/tex]
[tex]\Rightarrow (1+r)=\sqrt[14]{2}[/tex]
[tex]\Rightarrow r=\sqrt[14]{2}-1[/tex]
Now, to find the quantity after 21 days, we plug [tex]A_0[/tex] = 830, t= 21 days in exponential function
[tex]A=830( 1+\sqrt[14]{2}-1)^{21}[/tex]
[tex]\Rightarrow A=830(\sqrt[14]2)^{21}[/tex]
[tex]\Rightarrow A=830(2)^\frac{21}{14}[/tex]
[tex]\Rightarrow A=830(2)^\frac{3}{2}[/tex]
[tex]\Rightarrow A=2,347.59[/tex]
The value of the quantity after 21 days is 2,347.59.
Final answer:
To calculate the value of a quantity after 21 days when it doubles every 2 weeks with an initial value of 830, use the exponential growth formula [tex]N(t) = N_0 \times 2^{t/T}[/tex]. Plugging in the values, the quantity after 21 days is 2347.14, to the nearest hundredth.
Explanation:
Calculating Exponential Growth
To find the value of a quantity after 21 days when it has an initial value of 830 and doubles every 2 weeks, we can use the formula for exponential growth:
N(t) = N_0 × 2^(t/T)
Where:
N(t) is the future value after time t,
N_0 is the initial value (830),
t is the time period in days (21 days),
T is the doubling period in days (2 weeks = 14 days).
First, we convert 21 days into weeks: 21 days / 7 days per week = 3 weeks.
Next, let's find the value after 3 weeks. We plug our values into the exponential growth formula:
[tex]N(3) = 830 \times 2^{3/2}[/tex]
To calculate 3/2 weeks in terms of doubling periods:
3 weeks / 2 weeks per doubling period = 1.5 doubling periods.
Now we can calculate the quantity:
N(21) = [tex]830 \times 2^{1.5}[/tex] = 830 × 2.828 = 2347.14
To the nearest hundredth, the value of the quantity after 21 days is 2347.14.

What is the slope between the points (4,–1) and (–4,3)?
The formula for slope is [tex]\frac{rise}{run} = \frac{y2-y1}{x2-x1}[/tex].
Subtract y1 from y2. (y1= -1, y2 = 3)
3 - -1 = 4
Now subtract x1 from x2. (x1 = 4, x2 = -4)
-4 -4 = -8
Divide the difference between the y coordinates by the difference between the x coordinates.
[tex]\frac{4}{-8}[/tex] or 4 ÷ -8 = -0.5
Answer:The slope between the two points is -0.5.
Hope this helpsss
The slope between the points (4, –1) and (–4, 3) is calculated using the slope formula and is found to be –0.5.
Explanation:The slope of the line passing through the points (4,–1) and (–4,3) is calculated using the slope formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. For the given points:
y2 = 3y1 = –1x2 = –4x1 = 4Plugging these into the formula gives:
m = (3 - (–1)) / (–4 - 4) = 4 / –8 = –0.5.
The slope between the points (4, –1) and (–4, 3) is –0.5.
We are standing on the top of a 960 foot tall building and launch a small object upward. The object's vertical altitude, measured in feet, after t seconds is h ( t ) = − 16 t 2 + 64 t + 960 . What is the highest altitude that the object reaches?
Answer:2 seconds s(2) max ht = 264 ft two answer pick one at least
Step-by-step explanation:
..A person standing cloes to the edge on the top of a 200-foot building throws a baseball ... t = -b/2a t = -64/-32
The highest altitude the object reaches is 1024 feet.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
h(t) = -16t² + 64t + 960
Now,
h'(t) = -16 x 2t + 64 = -32t + 64
h''(t) = -32
This means,
h(t) has a maximum altitude at h'(t) = 0
Now,
h'(t) = 0
-32t + 64 = 0
-32t = -64
t = 2
Now,
h(2) = -16 x 2² + 64 x 2 + 960
h(2) = -16 x 4 + 128 + 960
h(2) = -64 + 128 + 960
h(2) = 1024 feet
Thus,
The highest altitude is 1024 feet.

A basket full of 10 apples costs 23$, another basket full of 15 apples costs 33$. The prices of the baskets are the same. How much will a basket full of 25 apples cost? Write an equation that tells the price Y for the number of apples X. Fill in the chart.
Answer:
Equations:
y + 10x = 23
y + 15x = 33
cost of basket with 25 apples = $53
Step-by-step explanation:
A basket with 10 apples cost $23 and a basket with 15 apples cost $33. Note that these costs also include the cost of the basket, which is same in both case. Let the cost of empty basket with "y" and cost of each apple be "x"
Cost of basket and 10 apples is $23. We can transform this statement into an equation as:
y + 10x = 23 Equation 1
Similarly,
Cost of basket and 15 apples is $33. This gives us another equation:
y + 15x = 33 Equation 2
Subtracting Equation 1 from Equation 2 , we get:
y + 15x - (y +10x) = 33 - 23
5x = 10
x = 2
Using the value of x in equation 1, we get:
y + 10(2)= 23
y = 23 - 20
y = 3
This means, cost of basket is $3 and cost of each apple is $2.
Now we can calculate the cost of basket with 25 apples, which will be:
Cost of basket + Cost of 25 apples = Total Cost
3 + 25(2) = 3 + 50 = $53
Answer:
10=23
15=23
25=53

Marcia biked 600 meters on friday. On saturday, she biked 3 kilometers. One sunday she biked 2 kilometers and 700 meters. How many kilometers did Marcia bike over the three days?
Answer:
6.3 km
Step-by-step explanation:
You want to know the total distance represented by segments of 600 m, 3 km, and 2km plus 700 m.
KilometerKilo- is a prefix meaning 1000. A kilometer is 1000 meters. That means we can write the distances as ...
600 m = 0.600 km3 km = 3.000 km2 km + 700 m = 2.700 kmTotalThe total of these distances is found by adding the decimal values in the usual way.
0.600 +3.000 +2.700 = 6.300
Marcia biked 6.3 km over the three days.

Consider the series
\sum_{n=1}^{\infty} \frac{(2 x)^n}{n}.
Find the interval of convergence of this power series by first using the ratio test to find its radius of convergence and then testing the series' behavior at the endpoints of the interval specified by the radius of convergence.
interval of convergence =
Answer:
(-\infty,-1/2) U (1/2,+\infty)
Step-by-step explanation:
You have the following series:
[tex]\sum_{n=1}^{\infty} \frac{(2 x)^n}{n}[/tex]
You calculate the radius of convergence by using the formula:
[tex]R= \lim_{n \to \infty} |\frac{a(x)_n}{a(x)_{n+1}}|= \lim_{n \to \infty} |\frac{\frac{(2x)^n}{n}}{\frac{(2x)^{n+1}}{n+1}}|\\\\=\lim_{n \to \infty} |\frac{\frac{(2x)^n}{n}}{\frac{(2x)^n(2x)}{n+1}}|=\lim_{n \to \infty}|\frac{n+1}{2xn}|=|\frac{1}{2x}|\lim_{n \to \infty}|1+\frac{1}{n}|=|\frac{1}{2x}|[/tex]
The radius of convergence is R=1/2x.
Hence, the interval of convergence is
|2x| < 1
|x| < 1/2
By evaluating in the extrems of the interval:
[tex]\sum_{n=1}^{\infty} \frac{(2 (\frac{1}{2}))^n}{n}=\sum_{n=1}^{\infty} \frac{(1)^n}{n}=0\\\\\sum_{n=1}^{\infty} \frac{(2 (-\frac{1}{2}))^n}{n}=\sum_{n=1}^{\infty} \frac{(-1)^n}{n}[/tex]
for x=-1/2 we obtain an Alternating Harmonic Series, for x=1/2 we obtain the divergent harmonic series. Thus the interval is:
(-\infty,-1/2) U [1/2,+\infty)
Answer:
Step-by-step explanation:
Recall the ratio test. Given a series [tex]\sum_{n=1}^{\infty}a_n[/tex] if
[tex] \lim_{n\to \infty} \left|\frac{a_{n+1}}{a_n}\right|<1[/tex]
Then, the series is absolutely convergent.
We will use this to the given series [tex]\sum_{n=1}^{\infty} \frac{(2 x)^n}{n}[/tex], where [tex] a_n = \frac{(2 x)^n}{n}[/tex]. Then, we want to find the values for which the series converges.
So
[tex] \lim_{n\to \infty} \left|\frac{(2x)^{n+1}}{n+1}\cdot \frac{n}{(2x)^n}\right|<1[/tex], which gives us that
[tex] |2x|\cdot\lim_{n\to \infty} \frac{n}{n+1}<1[/tex]
We have that [tex]\lim_{n\to \infty} \frac{n}{n+1}=1[/tex]. Then, we have that
[tex]|2x|<1[/tex],
which implies that |x|<1/2. So for [tex]x \in (-1/2,1/2)[/tex] the series converges absolutely.
We will replace x by the endpoints to check convergence.
Case 1, x=1/2:
In this case we have the following series:
[tex]\sum_{n=1}^{\infty} \frac{1}{n}[/tex] which is the harmonic series, which is know to diverge.
Case 2, x=-1/2:
In this case we have the following series:
[tex]\sum_{n=1}^{\infty} \frac{(-1)^n}{n}[/tex]
This is an alternating series with [tex]b_n = \frac{1}{n}[/tex]. Recall the alternating series test. If we have the following
[tex]\sum_{n=1}^\infty (-1)^nb_n [/tex] and[tex] b_n[/tex] meets the following criteria : bn is positive, bn is a decreasing sequence and it tends to zero as n tends to infinity, then the series converge.
Note that in this case, [tex]b_n = \frac{1}{n}[/tex] si always positive, its' limit is zero as n tends to infinity and it is decreasing, hence the series converge.
So, the final interval of convergence is
[tex] [\frac{-1}{2}, \frac{1}{2})[/tex]

Answer:
The equation to describe the situation is [tex]p-3=17.[/tex]
And, the total weight of the basket of apples was 20 pounds.
Step-by-step explanation:
The question is incomplete so, the complete question is below:
Liang bought a basket of apples to make pies for her friends. The basket of apples weighed p pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies. Write an equation to describe this situation. What was the total weight of the basket of apples?
Now, to write an equation to describe the situation. And to find the total weight of the basket of apples.
So, the basket of apples total weighed = [tex]p\ pounds.[/tex]
Liang ate apples weighed = 3 pounds.
And the apples left for the pies weighed = 17 pounds.
Now, to write an equation describing the situation:
[tex]p-3=17.[/tex]
Thus, the equation is [tex]p-3=17.[/tex]
Now, to get the total weight of the basket of apples:
[tex]p-3=17\\\\Adding\ both\ sides\ by\ 3\ we\ get:\\\\p=20[/tex]
Hence, the basket of apples total weighed = 20 pounds.
Therefore, the equation to describe the situation is [tex]p-3=17.[/tex]
And, the total weight of the basket of apples was 20 pounds.

780
Answer: 780
Step-by-step explanation: 30 numbers times 26 letters.
30 x 26=780
Final answer:
To find the total number of outcomes for selecting a number between 1 and 30 and a letter from the alphabet, you multiply the outcomes of each event together, resulting in 30 numbers multiplied by 26 letters, which equals 780 total outcomes.
Explanation:
The question asks for the total number of outcomes when picking a number from 1 to 30 and a letter from the alphabet. In mathematics, to calculate the total number of outcomes for two independent events, you multiply the number of outcomes for each event. There are 30 different outcomes for picking a number from 1 to 30, and, assuming a standard English alphabet, there are 26 outcomes for picking a letter from A to Z.
To find the total number of outcomes when one event is selecting a number and another event is selecting a letter, you multiply the two: 30 (numbers) × 26 (letters) = 780 total outcomes.

(e) This is a completely randomized design with four explanatory variables (factors).
Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad
(ii) 60-second ad,
Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.
All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.
