David has a bank account which pays interest at the rate of 1.5% per year, compounded annually. Determine what amount David
must have in the bank, given that he would like to draw an annual salary of $32,635.15 from his account at the end of each year
for 30 years. Round to the nearest cent.
Answers
Answer: the amount that David must have in the bank is $783243.6
Step-by-step explanation:
We would apply the formula for determining present annuity. It is expressed as
PV = R[1 - (1 + r)^- n]r
Where
PV represents the present value of the investment.
R represents the regular payments made(could be weekly, monthly)
r = represents interest rate/number of interval payments.
n represents the total number of payments made.
From the information given,
r = 1.5/100 = 0.015
n = 30 years
R = $32,635.15
Therefore,
PV = 32635.15[1 - (1 + 0.015)^- 30]/0.015
PV = 32635.15[1 - (1.015)^- 30]/0.015
PV = 32635.15[1 - 0.64]/0.015
PV = 32635.15[0.36]/0.015
PV = 32635.15 × 24
PV = $783243.6

A rectangular playground is 40 feet wide. Find the area of this playground, if the fence around it, including the gates, is 200 feet long.
Answers
Answer:
[tex]A=2400ft[/tex]
Step-by-step explanation:
A rectangle is a closed planer quadrilateral with four right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:
[tex]Perimeter=w+h+w+h=2w+2h\\\\Where:\\\\w=Width\\h=Height[/tex]
The ectangular playground is 40 feet wide, so:
[tex]w=40ft[/tex]
Therefore:
[tex]Perimeter=2w+2h\\\\200=2(40)+2h\\\\200=80+2h[/tex]
Solving for h:
[tex]2h=200-80\\\\2h=120\\\\h=\frac{120}{2} \\\\h=60ft[/tex]
The area of a rectangle is equal to the product of two of its contiguous sides, hence:
[tex]A=wh\\\\A=(40)(60)=2400ft[/tex]
I attached you a picture of the rectangle
complete the recursive formula of the geometric sequence 0.2,-1,5,-25
Answers
Answer:
s[1] = 0.2; s[n] = -5·s[n-1]
Step-by-step explanation:
To write a recursive formula, you need to know how a given term relates to the ones before it. Here, each term is -5 times the one before. So part of the formula is ...
s[n] = -5·s[n-1]
The other part of a recursive formula is the part that tells the initial values necessary to make this recursive function work. Here, one initial value is needed. We know that the first term is 0.2, so that's what we need to say:
s[1] = 0.2

Which of the following is an example of a matched pairs design? A. A teacher calculates the average scores of students on a pair of tests and wishes to see if this average is larger than 80%. B. A teacher compares the pre-test and post-test scores of students. C. A teacher compares the scores of students using a computer based method of instruction with scores of other students using a traditional method of instruction. D. A teacher compares the scores of students in her class on a standardized test with the national average score.
Answers
Answer:
B. A teacher compares the pre-test and post-test scores of students
Step-by-step explanation:
the answer is true, because it is a good example to compare the tests between students, we know that a matching pair design is a random model and is used when the experiment allows grouping subjects in pairs based on a variable and each pair will receive randomly a different handling, the answer A is not true because in the example all students are uniformly averaged and the variable is not correlated with subgroups, option c is incorrect because the variable was not randomized and generates classification bias and the option d is incorrect because the teacher compares a small sample as her class with a score of a total sample, but does not intervene on her students when selecting the corresponding group
Matched pair design describes an experimental technique whereby subjects having certain variable or characteristic are paired or matched based on that variable, usually called the key variable. Hence, an example of a matched pair design is "a teacher compares the pre-test and post-test scores of students."
In these type of experimental design, the key or common variable pertinent to both matched subjects is of utmost importance. The only option where, the variable shared is common is the pretest and posttest scores. In the other options, comparing traditional and computer based instructions doesn't match ; similarly, standardized score and national average do not match perfectly.Hence, the most appropriate option is A.

A seed randomly blows around a complex habitat. It may land on any of three different soil types: a high-quality soil that gives a 0.8 chance of seed survival, a medium-quality soil that gives a 0.3 chance of survival, and a low-quality soil that gives only a 0.1 chance of survival. These three soil types (high, medium, and low) are present in the habitat in proportions of 30:20:50, respectively. The probability that a seed lands on a particular soil type is proportional to the frequency of that type in the habitat.
a. Draw a probability tree to determine the probabilities of survival under all possible circumstances.b. What is the probability of survival of the seed, assuming that it lands?
Answers
Answer:
a) Attached.
b) Probabiltiy of survival = 0.35
Step-by-step explanation:
a) The probability tree is attached as a picture.
This is constructed with the two events (landing and survival), with their associated probabilities.
The events are dependant, as the probability of survival depends on the outcome of the first event (the soil where the seed landed).
b) The probability of survival can be calculated as the sum of the probabilities that include the event "survives":
[tex]P(s)=P(H\&s)+P(M\&s)+P(L\&s)\\\\P(s)=P(H)P(s|H)+P(M)P(s|M)+P(L)P(s|L)\\\\P(s)=0.3*0.8+0.2*0.3+0.5*0.1\\\\P(s)=0.24+0.06+0.05\\\\P(s)=0.35[/tex]
The first line adds the three joint events that end with survival (land on high quality soil H and survive S, for example).
The second line splits the probability but the survival is conditioned to the soil where the seed has landed. That is why it is a conditional probability.

How many hours will have elapsed when the father and his son are 20.16 miles apart?
Answers
Answer:
1.4 hours have elapsed when the father and his son are 20.16 miles apart
Step-by-step explanation:
The son runs at a speed of 8.1 mph.
The father runs at a speed of 6.3 mph.
They run in opposite directions, so per hour, their distance increases at the rate of 8.1 + 6.3 = 14.4 mph.
How many hours will have elapsed when the father and his son are 20.16 miles apart?
Rule of 3.
1 h - 14.4 miles
