A box of chocolates contains five milk chocolates, five dark chocolates, and five white chocolates. You randomly select and eat three chocolates. The first piece is milk chocolate, the second is dark chocolate, and the third is white chocolate. Is it independent or dependen?
Answers
The first piece is milk chocolate, the second is dark chocolate, and the third is white chocolate independent and the probability is 25/546.
What is probability ?Probability of something is the occurrence of a certain event out of the total events that can occur.
According to the given question
The total no. of chocolates in the box is
(5 + 5+ 5) = 15 chocolates.
The probability of eating a milk chocolate first a dark chocolate second and a white chocolate third is an independent event because occurrence of next event do not depend upon the previous event.
There are 5 milk chocolates.
So, probability of getting a milk chocolate first is
P(mc) = 5/15
= 1/3
Now the the chocolate can no be replaced because it is eaten
∴ Probability of getting a dark chocolate second is
P(dc) = 5/14 (as the total no. of chocolate is reduced by 1
because it has been eaten)
And the probability of getting a white chocolate in 3rd attempt is
P(wc) = 5/13
As the first piece is milk chocolate, the second is dark chocolate, and the third is white chocolate is an independent event their probability is
P(mc) ∩ P(dc) ∩ P(wc)
= P(mc) × P(dc) × P(wc)
= (1/3 × 5/14 × 5/13)
= 25/546.

A line passes through the point (6,-1) and is perpendicular to the line with equation - 2x + 3y = -6.
Which is the equation of the line?
Answers
Answer: y = − 3/2 x + 8
Step-by-step explanation:
Find the Perpendicular Line
Solve −2x + 3y = −6.
y = −2 + 2x/3
Find the slope when y = −2 + 2x/3 .
m = 2/3
The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.
[tex]m[/tex] perpendicular = [tex]-\frac{1}{\frac{2}{3} }[/tex]
Simplify to find the slope of the perpendicular line.
perpendicular = −3/2
Find the equation of the perpendicular line using the point-slope formula.
y + 1 = − 3/2
⋅ (x − 6)
Write in y = mx + b form.
y = − 3/2 x + 8

The net of a right rectangular prism is shown below. The measurements are given to the nearest tenth of a centimeter. What is the surface area of the prism?
Answers
Answer: c. 352.50 cm²
Step-by-step explanation:
Looking at the shape one can see that it is made up of 3 rectangles and 2 triangles.
The surface area will therefore be the sum of the areas of these 5 shapes.
Rectangle area = Length * width
= 7.5 * 13.5
= 101.25 cm²
There are 3 of them:
= 101.25 * 3
= 303.75 cm²
Triangles = 1/2 * base * height
= 1/2 * 7.5 * 6.5
= 24.375 cm ²
There are two of them:
= 24.375 * 2
= 48.75cm²
In total:
= 303.75 + 48.75
= 352.50 cm²

The price of a watch was increased by 20% to £162.
What was the price before the increase?
Answers
Step-by-step explanation:
Write equation. Let o be original price, r be rate of increase, P be the increased price. o+ro=P
Substitute values. Original price (o) is unknown, so that will stay as it is; we know that the increased price (P) is 162; we know that the rate of increase (r) is 20%, which in decimal form is 0.20 o+0.20o=162
Add like terms. o is the same as 1o. So 1+0.20 is 1.20. 1.20o=162
Isolate the variable (o). To isolate o, you need to divide both sides by 1.20. 1.20 divided by 1.20 is the same as 1. 162 divided by 1.20 is 135. o=135
Check your work. Plug in the values into the equation and check if it is correct: o+ro=P becomes (135)+(.20)(135)=162. That is simplified into 135+27=162, which is further simplified into 162=162
It’s correct, the answer is 135
