In 2 years, Duncan wants to buy a bicycle that costs $400.00. If he opens a savings account that earns 11% interest compounded annually, how much will he have to deposit as principal to have enough money in 2 years to buy the bike?
Answers
Answer:
Current deposit amount = $324.65 (Approx.)
Step-by-step explanation:
Given:
Cost of bicycle = $400
Future amount = $400
Rate of interest = 11% = 0.11
Number of year = 2 year
Find:
Current deposit amount
Computation:
Compound interest formula
A = P[1+r]ⁿ
Future amount = Current deposit[1+Rate of interest]ⁿ
400 = Current deposit[1+0.11]²
400 = Current deposit[1.11]²
400 = Current deposit[1.2321]
Current deposit amount = 400 /1.2321
Current deposit amount = $324.65 (Approx.)

A sector has a radius of 12 centimeters and an angle of 65 degrees. Find it's arc length.
A. 18.2 cm
B. 13.6 cm
C. 12.6 cm
D. 14.6 cm
Answers
Because the formula for arc length is: 2pi (r) * angle/360
So if we input our values in the formula we have:
2pi (12) * 65/360
Just input this into your calculator and you get the answer as 13.6 (1.DP)
Hope this helped
The arc length will be option B. 13.6 cm.
How to find the relation between angle subtended by the arc, the radius and the arc length?[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]
If radius of the circle is of r units, then

The superscript 'c' shows the angle measured in radians.
Given; A sector has a radius of 12 centimeters and an angle of 65 degrees.
So we input our values in the formula:
2π (12) x 65/360
= 24π x 65/360
= 13.6
Hence, the arc length will be option B. 13.6 cm.

Answers
Answer:
Kela will be able to travel for 7 stops before her money runs out.
Step-by-step explanation:
Since Kela wants to visit a friend who lives 8 kilometers away, and she'll ride the subway as she can before walking the rest of the way, and she needs to buy an access pass that costs $ 5.50 and there is also a fee of $ 1.25 for each stop, if Kela doesn't want to spend more than $ 15 on the trip, to determine the largest number of stops she can afford, the following calculation must be performed:
(15 - 5.5) / 1.25 = X
9.5 / 1.25 = X
7.6 = X
Therefore, Kela will be able to travel for 7 stops before her money runs out.

Answers
Answer:
10 g
Step-by-step explanation:
40/2 = 20 g
20/2 = 10 g
If half-life of a radioactive kind of tellurium is 2 months. If you start with 40 grams of it, then 10 gm of it left after 4 months.
What is Half life?Half-life is the time required for a quantity to reduce to half of its initial value.
Given,
The half-life of a radioactive kind of tellurium is 2 months
It started with 40 grams of radioactive kind of tellurium
As given, half is for two months
In first two months it becomes 20 gm
40/2= 20gm
In second two months the 20 gm is reduced by half
20 gm/2=10gm.
Hence, 10gm of radioactive kind of tellurium is left after 4 months.

A research scholar wants to know how many times per hour a certain strand of virus reproduces. The mean is found to be 4 reproductions and the population standard deviation is known to be 2.3. If a sample of 1083 was used for the study, construct the 99% confidence interval for the true mean number of reproductions per hour for the virus. Round your answers to one decimal place.
Answers
Answer:
The 99% confidence interval for the true mean number of reproductions per hour for the virus is between 3.8 and 4.2.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.575\frac{2.3}{\sqrt{1083}} = 0.18[/tex]
Rounding to one decimal place, 0.2.
The lower end of the interval is the sample mean subtracted by M. So it is 4 - 0.2 = 3.8 reproductions
The upper end of the interval is the sample mean added to M. So it is 4 + 0.2 = 4.2 reproductions.
The 99% confidence interval for the true mean number of reproductions per hour for the virus is between 3.8 and 4.2.
Which of the following are "like" terms: 6b 5x 4x x 2e
Answers
Answer:
5x, 4x and x.
Step-by-step explanation:
Like Terms. "Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. So say we have 4,5,and 3x. 4 and 5 would be like terms because they are just whole numbers. If we added another number with a coefficient of x, it would be 3x's like term. It's not as simple though, because a number having letters doesn't just make it a like term. It has to be the same letter(s). 4x and 5y are not like terms but 4x and 5x would be. 4xy and 5yz are not like terms but 5yz and 6yz would be like terms.
