A cereal company puts a small plastic bear in some of its cereal boxes. Customers who collect 10 of these bears win a grand priz

e.
Suppose that each box contains a bear with chance 1/5, independently of all other boxes. Suppose also that Rohan buys one box of this cereal each week.

Let T1T1 be the number of weeks it takes for Rohan to get his first bear.

Let T10T10 be the number of weeks it takes for Rohan to get his tenth bear.

Find the following probabilities. In each part, first write a math expression for the chance, and then use the code cell at the end of the exercise to find the numerical value. Provide the numerical value along with your math expression.

Note: Do not use stats.geom.pmf or stats.geom.cdf. You should be able to calculate the numerical value without these functions.

a) P(T1>12)P(T1>12)

b) P(T10=40)P(T10=40)

c) P(T10>40)P(T10>40)

d) P(T10>40∣T1=8)

What is the equation of the line with an x-intercept of -1 and a y-intercept of 2?
iragen [17]

Answer:

y = 2x + 2

Step-by-step explanation:

The general form

is;

y = mx + b

where m is the slope and b is the y-intercept

so we have;

y = mx + 2

To get m, substitute the point (-1,0)

So we have

0 = -m + 2

m = 2

So the equation is;

y = 2x + 2

Geometry help please!!!
julia-pushkina [17]
Before we begin, let's identify what kind of angles these are and are they related in any way?

These angles are both acute and they are both corresponding angles.
Corresponding angles are equal to each other, and we can use this fact to our advantage.

Since they are equal to each other, we can set the equations of 1 and 2 equal to each other. Like so,

1 = 2
83 - 2x = 92 - 3x

Now, we can solve for X by isolating it on one side.

83 - 2x = 92 - 3x

Add 3x to each side: (This basically moves the X on the right side to the left.)
83 - 2x + 3x = 92 - 3x + 3x
83 + x = 92

Subtract 83 on each side to isolate the X.
83 + x - 83 = 92 - 83 
x = 92 - 83
x = 9

Therefore, X equals 9. To check our work, we can substitute X for 9.
83 - 2(9) = 92 - 3(9)
83 - 18 = 92 - 27
65 = 65  - 
TRUE

So to conclude, Angle 1 is 65 degrees, Angle 2 is 65 degrees, and X equals 9.

Hope I could help you out!
