Answer:
In a betting game, you have a bag with red and blue balls. It has a total of 10 blue and 5 red balls. You take randomly 4 of them, one by one (without replacement). If you get more than 1 red balls you win 10 $
Is obtaining 1 or more red balls a dependent or independent event?
It's dependent, if you have 15 balls, and only 5 are red, then the probability of getting a red on the first try is 5/15. Assuming you do not get the red ball, in the second attempt the probability will be 5/14 ... That is, the probability of obtaining a red ball depends on the color of the ball that you have previously obtained.
You roll a dice 10 times and count the number of 5 you get.
Is obtaining 4 by 5 a dependent or independent event?
It's independent
The probability of obtaining a 5 when rolling a die will always be 1/6. Therefore, the probability of obtaining a 5 does not depend on you having obtained it before.
Answer:
f(x) = x^3 - x^2 -2x
Step-by-step explanation:
If x = a is a zero of a polynomial, then x-a is a factor of the polynomial. Given the factors of a polynomial, the polynomial can be obtained by multiplying the factors.
The factors of the given polynomial are;
x - 2
x + 1
x
Multiplying the first two factors;
(x-2)(x+1) = x^2 + x -2x -2
= x^2 -x -2
We finally multiply this result by x to obtain our polynomial;
f(x) = x ( x^2 -x -2)
= x^3 - x^2 -2x
which is a cubic polynomial since it has 3 roots.
Multiply 199.98 by 22%.
=199.98 * 22%
convert 22% to decimal: 22% ÷ 100
=199.98 * 0.22
=$43.9956
=rounded to $44
ANSWER: He will save $43.9956 (rounded to $44)
Hope this helps! :)
Answer:
y=-6x+8
Step-by-step explanation:
(-2,2) and (-8, 1)
m represents your slope.
so
this gets you 1/6 (this is your slope from these two points but we ened to find the perpendicular slope)
all you do is take the is make 1/6= -6 (this your perpendicular slope, basically just take the reciprocal of the original slope)
so now use the equation y-y1=m(x-x1) ---> the y1, and x1 represent the place holders for the point (3,-10)
y+10=-6(x-3) (move the 10 over)
y=-6(x-3)-10
y=-6x+18-10
y=-6x+8
