Blake is cutting a piece of rope into fourths. if each piece is 16 inches long, what is the length of the entire rope?

Answers

Answer:

64inches.

Step-by-step explanation:

Let x represent the length of entire rope.

Division Equation:

\frac{x}{4} = 16

\frac{x}{4} X 4 =16x4 (Multiply each side by 4)

x=64

Therefore, length of entire rope is 64 inch.

Answers

Answer:

Step-by-step explanation:

We know that ABD is 30 degrees. To find BC, we need to use sin.

Equation:

BC = 16*sin(30 degrees) I recommend using a calculator to find the sine if you don't know what it means and how to use it. Sine is basically the side length opposite of the angle over the hypotenuse of the right triangle.

BC = 16*0.5

BC = 8

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.

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]

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.
