Answer:
Hello love! Well sense we are aiming for heads thats a 1/2 chance sense a coin has two sides heads and tails and sense we are aiming for a numbers higher then 3 on a dice our probability for that will be 3/6 sense the numbers higher then 3 on a dice our 4, 5 and 6 so we would multiply those probability so 1/2 x 3/6 and that equals our answer 1/4

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?
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]
[tex]p = 0.05[/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.
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).
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 )
Answer:
(-3,7)

Brainiest and 35 points for first correct answer. Purposely wrong answers will be deleted and reported, as well as wrong and guessed answers. Thank you.
Points A and B have opposite x-coordinates but the same y-coordinates.
On a coordinate plane, point A is 2 units to the left and 3 units up. Point B is 2 units to the right and 3 units up.
How many units away are each of the points from the y-axis?
2
3
4
5
Answer:
they are 4 unit away from the Y axis because you are counting the square units from Y not the lines across.

Which expression is equivalent to
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
Answer:
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
TA=48+12.56
TA=60.56 sq cm
