Answer: 24.1

Step-by-step explanation: Ok, to make this easier to multiply I like turning the fractions into decimals. To convert it into a decimal all we have to do is:

1 divided by 8 = 0.12

7 divided by 8 = 0.87

Now, let's multiply...

4.12 x 5.87 = 24.1

I hope this helps!

A class consists of 12 boys and 12 girls. The teacher picks five students to present their work to the rest of the class
Varvara68 [4.7K]

Answer:

0.01863, yes preference

Step-by-step explanation:

given that a class consists of 12 boys and 12 girls. The teacher picks five students to present their work to the rest of the class  and says that the five students are being selected at random

Here selecting any 5 students from the group of total 24 students is combination because order does not matter.

Total no of ways of selecting any 5 from total 24 = 24C5\\=42504

No of ways of selecting only 5 girls = No of ways of selecting random 5 girls from total 12 girls

= 12C5\\=792

a) the probability be that all five students

selected are girls=\frac{792}{42504} \\=0.01863

b) Since the probability for selecting all girls is very small and near to 0, it is unusual to select all girls if done at random.  Hence the teacher had a preference for girls.

Mr. Nelson lost one of his students' test
amid [387]

Complete question :

Mr. Nelson lost one of his students' test papers. He knows that the other 4 students scored as follows: 60, 62, 56, 57. He also knows that the average score is 59.2. What is the score on the missing paper?

Answer:

61

Step-by-step explanation:

Given the following :

Total number of students = 4 + 1 missing = 5

Score on the four avaliable papers = 60, 62, 56, 57

Average score of the 5 papers = 59.2

Score on missing paper :

Sum of each score / number of papers

Sum of each score = sum of available scores + missing score

Let missing score = m

(60 + 62 + 56 + 57 + m) = 235 + m

Recall:

Average = total sum / number of observations

Hence,

59.2 = (235 + m) / 5

59.2 × 5 = 235 + m

296 = 235 + m

m = 296 - 235

m = 61

Missing score = 61
