The probability that Aiden randomly selects an oatmeal cookie from the bag, eats it, then randomly selects a chocolate chip cookie is 0.0721

<h3>How to determine the probability?</h3>

The distribution of the cookies is given as:

  • 9 chocolate chip cookies
  • 8 peanut butter cookies
  • 8 sugar cookies
  • 9 oatmeal cookies

When he eats a cookie, the number of cookies reduces by 1

So, the required probability is:

P(Oatmeal and Chocolate) = Oatmeal/Total * Chocolate/Total - 1

This gives

P(Oatmeal and Chocolate) = 9/(9 + 8 + 8 + 9) * 9/(9 + 8 + 8 + 9 -1)

Evaluate

P(Oatmeal and Chocolate) = 0.0721

Hence, the probability is 0.0721

UkoKoshka [18]

Answer:

Pay $6.75 and save $2.25

Step-by-step explanation:

If the store has a sale for 25% off, then you pay 75%. Find the sales price by multiplying $9 by 0.75.

9*0.75 = 6.75

This means you save 9 -6.75 = 2.25.

An isosceles triangle has 2 angles that measure 37 degrees each. Write 2 different equations that could be solved to find the me
LuckyWell [14K]

Answer:

The third angle of isosceles triangle is 106°   .

Step-by-step explanation:

Given as :

The measures of equal angles of isosceles triangle = 37°

i.e \Theta _1 =  \Theta _2 = 37°

Let The third angle of isosceles triangle =  \Theta _3

Now,

An isosceles triangle is that whose opposite sides are equal and two angles are equal

<u>Now, From the property of Triangle</u>

The sum of all three angles of Triangle = 180°

i.e  \Theta _1 +  \Theta _2 +  \Theta _3 = 180°

∵  \Theta _1 =  \Theta _2 = 37° (given)

So,  37° +  37° +  \Theta _3 = 180°

Or, 74° +  \Theta _3 = 180°

Or,  \Theta _3 = 180° - 74°

∴  \Theta _3 = 106°

So, The third angle of isosceles triangle =  \Theta _3 = 106°

Hence,The third angle of isosceles triangle is 106°   . Answer
