According to the graph, what is the experimental probability of selecting the letter E?

Daniel [21]

The experimental probability of letter E is: 3/25

Step-by-step explanation:

The given diagram is the number of outcomes for each letter is given

We have to find the total number of outcomes for finding the experimental probability of letter E

So,

Total outcomes = n(S) = 5+12+8+10+6+9 = 50

Number of outcomes for Letter E = n(E) = 6

So the experimental probability will be:

$P(E) = \frac{n(E)}{n(S)}\\\\=\frac{6}{50}\\\\= \frac{3}{25}$

Hence,

The experimental probability of letter E is: 3/25

The factor levels are :

Level -1 which comprises of 3 highschool,

Level -2 which comprises of highschool and the highschool has 4 sections and each section has 24 students

Factor level combinations:

Level 1 : computer and standard based combination

C) Within the subject : 24 students

Between subject : High school

D) score of the test

A) The study is experimental because of the random assignment of two different types of instruction to the students which will control/affect the technique of teaching without just observing the performance of the students from the side

B) The important factors are : Type of instruction, scores and High schools,

The factor levels are :

Level -1 which comprises of 3 highschool,

Level -2 which comprises of highschool and the highschool has 4 sections and each section has 24 students

Factor level combinations:

Level 1 : computer and standard based combination

C) Within the subject : 24 students

Between subject : High school

A small bar of gold measures 40 mm by 25 mm by 2 mm. One cubic millimeter of gold weighs about 0.0005 ounce. Find the volume in

slamgirl [31]

I'm believing that you have the measurements in the right order, lwh, the Volume would be 5,000. You'd take 40 x 25 x 2= 5,000.

The weight is 2.5 oz. You get this answer by taking the Volume, 5,000, and multiply it by 0.0005 and you get 2.5 ounces.

I hope this helps!
