A bag has 6 watermelon, 5 grape and 1 green apple jolly rancher. . What is the probability of picking a
watermelon, put it back then green apple?
Answers
Answer:
1/24
Step-by-step explanation:
We want to find the probability of picking a watermelon AND picking a green apple right after. These events are completely independent of each other as the watermelon is put back, and picking a watermelon/green apple does not affect the chances of getting the other the next/previous time. The formula for this is P(A) * P(B), with P(A) being the probability of event A happening and P(B) being the probability of event B happening. It does not matter which event is which.
Let's say picking a watermelon is event A and picking a green apple is event B. There are 6 watermelons and 6+5+1 = 12 jolly ranchers, so there is a 6/12 = 1/2 chance of picking a watermelon. There is 1 green apple and still 12 jolly ranchers, so there is a 1/12 chance of picking a green apple jolly rancher.
Multiplying these two, we get (1/2) * (1/12) = 1/24

find the coordinates of the points of intersection of the line 2x+3y+2=0 with the curve 2xy=-1
no spam plz fast
Answers
y = -1/(2x)
Substitute for y in the line equation
2x +3(-1/2x) + 2 = 0
Multiply every term by 2x
4x^2 - 3 + 4x = 0
4x^2 + 4x - 3 = 0
(2x - 1)(2x + 3) = 0
If 2x - 1 = 0 then
2x = 1
x = 1/2
y = -1/(2 x 1/2) = -1
If 2x + 3 = 0 then
2x = -3
x = -1.5
y = -1/(2 x -1.5) = -1/3
The points of intersection are (1/2, -1) and (-1.5, -1/3)
Sorry about the mixture of fractions and decimals ;)
The point of intersection of the line 2x+3y+2=0 with the curve 2xy = -1 will be (1/2, - 1) and (1/6, 1/3).
What is substitution method?To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The equation of lines are,
⇒ 2x + 3y + 2 = 0
⇒ 2xy = - 1
Now,
Since, The equation of lines are,
⇒ 2x + 3y + 2 = 0 ..(i)
⇒ 2xy = - 1 ..(ii)
From (ii);
⇒ 2xy = - 1
⇒ x = - 1/2y
Put above value in (i), we get;
⇒ 2 × - 1/2y + 3y + 2 = 0
⇒ - 1/y + 3y + 2 = 0
⇒ - 1 + 3y² + 2y = 0
⇒ 3y² + 2y - 1 = 0
⇒ 3y² + 3y - y - 1 = 0
⇒ 3y (y + 1) - 1 (y + 1) = 0
⇒ (3y - 1) (y + 1) = 0
⇒ y = 1/3
And, y = - 1
So, The value of x is,
⇒ x = - 1/2y
⇒ x = - 1/2 × - 1
⇒ x = 1/2
And, x = - 1/2 × 1/3
⇒ x = 1/6
Thus, The intersection point on the lines = (1/2, - 1) and (1/6, 1/3)

square root of the quantity x minus 2 end quantity plus 8 equals x
solve for x
Answers
Answer:
x = 11.
Step-by-step explanation:
√(x - 2) + 8 = x
√(x - 2) = x - 8
Square both sides:
x - 2 = (x - 8)^2
x - 2 = x^2 - 16x + 64
x^2 - 17x + 66 = 0
(x - 6)(x - 11) = 0
x = 6, 11.
With this type of question we could have extraneous roots so:
Check these 2 roots:
x = 6:
√(2 - 6) + 8 = √(-4)+8 <----- has no real value so this is not a root,

1)what is the measure of the segment AB
2)what is the measure of segment CD
how so?
Answers
Answer:
AB = 18, CD = 16
Step-by-step explanation:
The 3 segments make the whole line , that is
AB + BC + CD = AD , substitute values
AB + 20 + (BD - BC) = 54
AB + 20 + (36 - 20) = 54
AB + 20 + 16 = 54
AB + 36 = 54 ( subtract 36 from both sides )
AB = 18
-----------------------------------------------------
BC + CD = BD , substitute values
20 + CD = 36 ( subtract 20 from both sides )
CD = 16
