An investment of $500 increases at a rate of 12.5% per year. What is the value of the investment after 30 years? Round to the nearest dollar.

Answers

Answer 1

Answer:

Here's the equation:

0.125(500) + 500

But because it is 30 years:

30(0.125(500)) + 500

3.75(500) + 500

We can make it simpler:

4.75(500)

2375

You will have $2375

O dreaptă (d) și punctele A,B și C în aceasta ordine stind ca AB=10cm; BC=14cm desemnați lungimea segmentului [AC]=? Vă rogg dau coroana!!!!la cine e corect

Answers

Answer:

Length of line AC = 24 cm

Step-by-step explanation:

Given:

Length of line AB = 10 cm

Length of line BC = 14 cm

Find:

Length of line AC

Computation:

We know that line AB and BC are two part of line AC

So,

AC = AB + BC

Length of line AC = Length of line AB + Length of line BC

Length of line AC = 10 + 14

Length of line AC = 24 cm

Jamie recorded the number of points she scored during her last 5 basketball games. She scored, 15, 25, 10, 2, and 8 points. What is the mean absolute deviation of the points she scored during the last five games?

Answers

Answer:

6.4

Step-by-step explanation:

Given scores:

15, 25, 10, 2, and 8

Mean of the scores:

(15 + 25 + 10 + 2 + 8)/5 = 12

Absolute deviations:

|15 - 12|= 3|25 - 12|= 13|10 - 12| = 2 |2 - 12| = 10|8 - 12| = 4

Sum of absolute deviations:

3 + 13 + 2 + 10 + 4 = 32

Mean absolute deviation:

32/5 = 6.4

total no of game (n)=5

score =15, 25, 10, 2, and 8 points

mean= sum of score/no.of game

=(15+25+10+2+8)/5=60/5=12

absolute deviation of

15=\15-12\=3

25=\25-12\=13

10=\10-12\=2

2=\2-12\=10

8=\8-12\=4

mean absolute deviation=

(3+13+2+10+4)/5=3.6

is the mean absolute deviation of the points she scored during the last five games.

3. People with type O-negative blood are universal donors (any patient can
receive a transfusion of O-negative blood). Only about 6.6% of the American
population has O-negative blood. If 270 unrelated people give blood in a certain
week, how many of these people do we expect to be universal donors? (Hint:
Remember to convert percent numbers to decimals before multiplying.)
PLEASE HELP

Answers

Answer:

We expect 17.82, that is, approximately 18 people to be universal donors.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they are universal donors, or they are not. The probability of a person being an universal donor is independent of any other person. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Only about 6.6% of the American population has O-negative blood.

This means that [tex]p = 0.066[/tex]

If 270 unrelated people give blood in a certain week, how many of these people do we expect to be universal donors?

This is E(X) when [tex]n = 270[/tex]. So

[tex]E(X) = np = 270*0.066 = 17.82[/tex]

We expect 17.82, that is, approximately 18 people to be universal donors.

Answers

The function that best models for the data is y = -200 (x-4)^2 + 800.

What is a function?

A function is a mathematical expression that describes how factors are related. In this case, how the price is related to the profit.

How to determine if a function models the data?

The best way to determine this is to solve the expression and verify if the answer is correct.

For example, we know that at 4 (x) dollars, the daily profit is $800 (y). Let's now the different options:

y= -8 (x+4)^2 + 800y= -8 (4+4)^2 + 800y= -8 (8)^2 + 800y= -8 (36) + 800y=-8 (288) + 800y= -2304 + 800y= -1504

y= -8 (x-4)^2 + 800y= -8 (4-4)^2 + 800y= -8 (0)^2 + 800y= -8 (0) + 800y= 0 + 800y= 800

y= -200 (4+4)^2+ 800y= -200 (8)^2 + 800y= -200 (36) + 800y= -200 (36) + 800y= -7200 + 800y= -6400

y= -200 (x-4)^2 + 800y= -200 (4-4)^2 + 800y= -200 (0)^2 + 800y= -200 (0) + 800y= 0 + 800y= 800

This means B and D are possible options, however, when verified with other results such as $6 the correct one is option D.

The quadratic equation is given by y = -200x² + 1600x - 2400.

Quadratic equation formula

The standard form of the quadratic equation is:

y = ax² + bx + c

Where a,b,c are constants.

Let y represent the daily profit for x bread price.

At point (2, 0):

0 = a(2)² + b(2) + c

4a + 2b + c = 0 (1)

At point (4, 800):

800 = a(4)² + b(4) + c

16a + 4b + c = 800 (2)

At point (6, 0):

0 = a(6)² + b(6) + c

36a + 6b + c = 0 (3)

From all the equations:

a = -200, b = 1600, c = -2400

The quadratic equation is given by y = -200x² + 1600x - 2400.

A positive angle less than 360 degrees that is coterminal with -5 degrees is

Answers

Answer:

[tex]\theta = 355[/tex]

Step-by-step explanation:

Given

Let the angle be [tex]\theta[/tex]

[tex]\theta < 360[/tex]

[tex]\theta[/tex] is co-terminal with -5

Required

Find [tex]\theta[/tex]

Start by dividing 5 by 360 (ignore the negative)

[tex]\frac{5}{360} = 0.0138[/tex]

The nearest integer greater than 0.0138 is 1.

This implies that if you were to draw for this problem, the circle you would draw to show -5 degrees would go around 1 time

So, [tex]\theta[/tex] is calculated as:

[tex]\theta = -5 + 1*360[/tex]

[tex]\theta = -5 +360[/tex]

[tex]\theta = 355[/tex]
