You measure 33 backpacks' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 12
saul85 [17]

Answer:

E=3.4363

Step-by-step explanation:

#Given a significance level of \alpha=1-CI=1-0.90=0.1 and

\bar x=36, \ \sigma=12.1 \ n=41, the critical value is,z_\alpha_/_2=z_\alpha_/_0_._0_5=1.645

#the margin of error can then be calculated as:

E=z_\alpha_/_2\times\frac{\sigma}{\sqrt n}=1.645\times \frac{12.1}{\sqrt 33}\\\approx 3.4363

Hence the margin of error is 3.4363

Link is coloring a triforce, which consists of four equilateral triangles and is depicted below. He has three colors to use: gol
3241004551 [841]

Answer:

12

Step-by-step explanation:

For the top triangle, he has 3 options

3C1 = 3

For the middle one, he can't use the top triangle's colour, so 2 options

2C1 = 2

For the ones on sides of the middle one, 2 options each

2C1 × 2C1 = 4

3 × 2 × 2 × 2 = 24

These include all three outer ones same, so subtract 3

Also, these include 2 of the three outer ones same, so subtract:

3C2 × 3 = 9

24 - 3 - 9 = 12
