Pippa's bank account pays 2.5% compound interest per annum and her bank
balance is £3200. After 3 years, how much will Pippa's bank balance be?
Answer:
£3446.05
Step-by-step explanation:
the interest for the first year
=£3200×2.5%
=£3200×2.5/100
=£80
the balance
=£3200+£80
=£3280
the interest for the second year
=£3280×2.5%
=£3280×2.5/100
=£82
the balance
=£3280+£82
=£3362
the interest for the third year
=£3362×2.5%
=£3362×2.5/100
=£84.05
the balance
=£3362+£84.05
=£3446.05

Step-by-step explanation:
The chamber of commerce for a beach town asked a random sample of city-dwellers, "Would you like to live at the beach?” Based on this survey, the 95% confidence interval for the population proportion of city-dwellers who would like to live at the beach is (0.56, 0.62).
Based on this poll, a chamber of commerce member claims that more than half of city-dwellers would prefer to live at the beach.
Use the confidence interval to evaluate this claim and select the true statement.
Yes, it is reasonable to assume this because all reasonable values in the confidence interval are greater than 0.50.
We cannot determine this without taking a census of all city-dwellers.
No, it is not reasonable to assume this because another 95% confidence interval might not be entirely above 0.50.
No, it is not reasonable to assume this because there are only two choices and the proportion of city-dwellers who should prefer either is exactly 0.50, not more than 0.50.

Expand and simplify 3(C - 2d) - 2(2C - 3d).
Answer:
-C
Step-by-step explanation:
3(C - 2d) - 2(2C - 3d).
Distribute
3C - 6d - 4C +6d
Combine like terms
3C -4C -6d +6d
-C
Answer:
-C
Step-by-step explanation:
3(C - 2d) - 2(2C - 3d) =
= 3C - 6d - 4C + 6d
= 3C - 4C - 6d + 6d
= -C
What should be included in a financial plan to protect assets?
0.3(3a-4)-0.05(8a)(-7a)
Answer:
2.8a²+0.9a - 1.2
Step-by-step explanation:
Given the expression 0.3(3a-4)-0.05(8a)(-7a)
Expand using the distributive law
0.3(3a-4)-0.05(8a)(-7a)
0.3(3a)-0.3(4)-0.05(8a)(-7a)
0.9a-1.2 - 0.05(8a)(-7a)
0.9a - 1.2 + 2.8a²
Rearrange
2.8a²+0.9a - 1.2
Hence the required expression is 2.8a²+0.9a - 1.2

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 410 gram setting. It is believed that the machine is underfilling the bags. A 22 bag sample had a mean of 408 grams with a standard deviation of 14. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the bags are underfilled

The smaller the sample, the less variability we will see. True or false
Answer: Hewo, there! your answer is Below
False would be my answer
Step-by-step explanation:
As the sample sizes increase, the variability of each sampling distribution decreases so that they become increasingly more leptokurtic. The range of the sampling distribution is smaller than the range of the original population.
Hope this helps you!!
Have a great day!!!

Consider harmonic oscillators with mass m, spring constant k, and damping coefficient b. For the values specified,
a. write the second-order differential equation and the corresponding first-order system.
b. find the eigenvalues and eigenvectors of the linear system.
c. classify the oscillator (as underdamped, overdamped, critically damped, or undamped) and, when appropriate, give the natural period.
d. sketch the phase portrait of the associated linear system and include the solution curve for the given initial condition.
Answer:
a) attached below
b) Eigen values : λ1 = -1 and λ2 = - 1/2
Eigenvector : V1 = - y1 and V2 = ( - 1/2 ) y2
c) since the Oscillator is > 0 hence it is Overdamped
Step-by-step explanation:
Lets take : m = 2 , k = 1 and b = 3
a) Second -order differential equation and the first order system
attached below
b) determine the eigenvalues and eigenvectors of the Linear system
Eigen values : λ1 = -1 and λ2 = - 1/2
Eigenvector : V1 = - y1 and V2 = ( - 1/2 ) y2
attached below is the detailed solution
c) The oscillator is classified as OVERDAMPED
To determine if the oscillator is damped, underdamped, or overdamped we will apply the relation below
b^2 - 4km
( 3 )^2 - 4(1)(2) = 1
since the Oscillator is > 0 hence it is Overdamped
d) Attached below is the phase portrait of the associated linear system
y(0) = 0
v(0) = 0

Which equation can be used to solve for x in the
following diagram?
(3x + 12)
Choose 1 answer:
3x + 12) + x = 180
(3x + 12) = x
3x = 180 + x
(3x + 12) + x = 90
The expression used to solve for x will be 3x + 12) + x = 180. The correct option is A.
What is the supplementary angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. The angles having the sum of 180 degrees will be called supplementary angles.
Given that there are two angles one is 3x + 12 and the other is x separated by the inclined line on the horizontal line.
From the supplementary angle property, the sum of the two angles is equal to 180 degree.
3x + 12 + x = 180
Therefore, the expression used to solve for x will be 3x + 12) + x = 180.
