Answer:

0.64 is the proportion of students in the population who failed to notice the woman in the gorilla suit

Step-by-step explanation:

We are given the following in the question:

Total number of students, n = 25

Number of student who noticed woman in gorilla suit = 9

Number of student who failed to notice woman in gorilla suit, x = 25 - 9 = 16

We have to find the proportion of the students in the population who failed to notice the woman in the gorilla suit.

Formula:

p = \dfrac{x}{n} = \dfrac{16}{25} =0.64

0.64 is the proportion of students in the population who failed to notice the woman in the gorilla suit

Find the probability of getting exactly 6 girls in 8 births.
AnnyKZ [126]

Answer:

The probability of getting exactly 6 girls in 8 births is 0.1093

Step-by-step explanation:

Given : 6 girls in 8 births.

To find : The probability of getting exactly 6 girls in 8 births.

Solution :

The probability of getting girl is \frac{1}{2}

The probability of getting 6 girl is (\frac{1}{2})^6

Since we have 6 girls,

We also need to find the probability of getting 2 boys, which is  

(\frac{1}{2})^2

There are ^8C_6 ways to get 6 girls in 8 births

i.e, ^8C_6=\frac{8!}{6!\times 2!}

^8C_6=\frac{8\times 7\times 6!}{6!\times 2\times 1}

^8C_6=28

There are 28 ways to get 6 girls in 8 births.

The probability of getting exactly 6 girls in 8 births.

=28\times (\frac{1}{2})^6\times (\frac{1}{2})^2

=28\times 0.015625\times 0.25

=0.109375

Therefore, The probability of getting exactly 6 girls in 8 births is 0.1093

Use the elimination method to solve the system of equations. <br><br> X+y=-3<br> X-y=13
Olin [163]
So I will choose to cancel the y first because that is easiest. To do this, add both equations together.
x+y = -3
+
x - y = 13
This will give us:
2x = 10
therefore, x = 5
Now, we can plug this into the first equation to find y
5+y = -3
y = -3 - 5 
y = -8

Answer:
x = 5
y = -8

Hope this helped!! :D
