Answer 1

since we know that 40% = $20. we can understand that 80% = $40. since books and savings combine to 40%. this means books and savings mean $20. now that we have found how much 80% of money she has. we can find the remaining. 100% - 80% = 20%. we can divide our ratio 40% = $20 by 2 too see how much money is 20%. in which is %10

now we add up and get $50 in total.

hope this helps :D

I play a gambling game in which I will win different amounts of money with different likelihood's. Suppose that I win X dollars with a probability of P(X) (if C is negative I am losing money). The distribution is as follows: what is the appropriate value of P?

Answers

Answer:

[tex]p = 0.05[/tex]

Step-by-step explanation:

Given

See attachment for the distribution

Required

Find p

To find p, we make use of:

[tex]\sum P(x) = 1[/tex]

So, we have:

[tex]0.50 + 0.25 + 0.13 + 0.07 + p = 1[/tex]

[tex]0.95 + p = 1[/tex]

Make p the subject

[tex]p = 1 - 0.95[/tex]

A researcher wishes to estimate the proportion of college students who cheat on exams. A poll of 530 college students showed that 21% of them had, or intended to, cheat on examinations. Find the 95% confidence interval for the population proportion. Round to four decimal places.

Answers

Answer:

(0.1753 ; 0.2447)

Step-by-step explanation:

Using the relation :

Confidence interval :

p ± margin of error

p = 0.21

1 - p = 0.79

n = 530

Zcritical at 95% confidence level = 1.96

Margin of Error : Zcritical * sqrt[(p(1-p))/n]

1.96 * sqrt[(0.21(0.79))/530]

1.96 * 0.0176923 = 0.0346769

Margin of Error = 0.0346769

Lower boundary = 0.21 - 0.0347 = 0.1753

Upper boundary = 0.21 + 0.0347 = 0.2447

Confidence interval :

(0.1753 ; 0.2447)

PLEASE HELP! Find the midpoint given (0,11) and (-6,3).

Answers

Answer:

(- 3, 7 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (0, 11) and (x₂, y₂ ) = (- 6, 3) , then

midpoint = ( [tex]\frac{0-6}{2}[/tex], [tex]\frac{11+3}{2}[/tex] ) = ( [tex]\frac{-6}{2}[/tex], [tex]\frac{14}{2}[/tex] ) = (- 3, 7 )

Which expression is equivalent to

Answers

Answer:

B) x^(5/3)*y^(1/3)

Step-by-step explanation:

Taking the cube root of a number is the same as raising it to the 1/3 power:

∛x=x^1/3

∛(x⁵y) = x^(5(1/3))*y^(1/3)=x^(5/3)*y^(1/3)

Remember to multiply exponents when raising an exponent to an exponent and distribute the 1/3 to each exponent!

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 15 cm long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the bookmark? Use 3.14 for pi

Answers

The area of the rectangle is Length x width. So 12x4 would =48 sq cm. The area of the circle is ( 3.14 ) x r2.

The area of the circle would be = (3.14)x2^2)=12.56 cm sq.

So the total area is= Area of rectangle +Area of circle
