4. Some scrabble letters are laid out that spell RECORDER. If they are all turned over and scrambled,
Ivanshal [37]

Answer: The answers are (a)1/8th (b) 0.125 (c) 12.5%

Step-by-step explanation:

How I drew this conclusion is, you have 8 letters in RECORDER so its 8/64 the same spot for every letter which simplifies to 1/8th. Now for the decimal divide 8 into 64 to get 0.125 decimal form. Lastly, for the percent 8 * 100 = 0.125 then 0.125 * 100 gets you 12.5%. Hope this helps you understand good luck.

Mekhanik [1.2K]

Answer:<em> 44 matches</em>

Step-by-step explanation:

<em>Let's take the given information</em>

<em>They won 37 matches</em>

<em>1/9th of their matches resulted in a draw</em>

<em>1/9 out of 90 is 9</em>

<em>You can take 90/9 and you will get 9</em>

<em>Now let us add 37+9 and you get 47</em>

<em>Now take 90-47</em>

<em>44 Matches lost</em>

<em>22/45 or 44/90</em>

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.

I need to figure out what x is
Svet_ta [14]
For all triangles, the angle sum is 180°, therfore we can add all the angles up to solve x
54 + 55 + x + 74 =180
183 + x =180
X = 180 - 183
X = - 3 °
Don't worry, negative result is normal and possible.
