Find the total amount of interest on a savings account if the principal is $9400 and the bank gives a rate of 6% compounded quarterly for the next 6 years.

Answers

Answer 1

Answer:

Answer:

4037.3264$

Step-by-step explanation:

Total amount of money after 6 years:

A = P x (1 + rate)^time

= 9400 x ( 1 + (6/100)/4)^(6 x 4)

= 13437.3264$

=> Total amount of interest after 6 years:

I = A - P = 13437.3264 - 9400 = 4037.3264$

1) A 15 foot flagpole casts an 11 foot shadow. At the exact same time a 28 foot tree casts a shadow. Which proportion would correctly find the length of the tree's shadow? A) x 28 = 11 15 B) x 28 = 15 11 C) 28 x = 11 15 D) x 15 = 11 28

Answers

The model involves similar triangles with the ratios of corresponding sides being equal

let x be the length of the tree's shadow, then

$(28)/(15)$ = $(x)/(11)$ ( cross- multiply )

15x = 11 × 28

The probability that a person has a certain disease is 0.03. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually present, the probability that the medical diagnostic test will give a positive result (indicating that the disease is present) is 0.92. Of the disease is not actually present, the probability of a positive test result (indicating that the disease is present) is 0.01. a. If the medical diagnostic test has given a positive result (indicating that the disease is present), what is the probability that the disease is actually present

Answers

Answer: 0.74

Step-by-step explanation:

A= "The person is sick"

B= "The test gives a positive result"

P(A)=0.03

P(B|A)=0.92

P(B|A')=0.01

P(A')=1-P(A)=1-0.03=0.97

P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373

Based in Bayes Rule

P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74

A linear function m models the amount of milk sold by a farm per month. The amount decreases 500 gallons for every $1 increase in price. Graph m when m(0)=3000. Identify the slope. Interpret the x- and y-intercepts of the graph.

Answers

The linear function that models this situation is:

$m(x) = 3000 - 500x, 0 \leq x \leq 6$

The y-intercept is y = 3000, which means that when there is no increase on the price, the farm sells 3000 gallons.
The x-intercept is x = 6, which means that if the price increases $6, no gallons will be sold.
The slope is of -500.
