Answer:

7x-y

Step-by-step explanation:

You can make 2x and 5x togheter because both have an X. You can't subtrakt Y from 7x, because X and Y are different variables.

Answer:

Option C

Step-by-step explanation:

3\frac{1}{5} \times 2\frac{1}{5}

Lets convert it into improper fraction.

\frac{16}{5} \times \frac{11}{5} = \frac{16 \times 11}{5 \times 5} = \frac{176}{25}

Lets convert \frac{176}{25} into a mixed fraction.

=> \frac{176}{25} = 7\frac{1}{25} = 7.04

Rounding off 7.04 gives 7 and rounding 7 further gives 10.

So , the estimate of the product is 10

If a student was randomly guessing while completing a 20 question multiple choice exam, what is the probability they would score
mario62 [17]

Answer:

you want 4 correct and 16 incorrect

there are 20 questions

each question has four answers, so

P(right answer) = 1/4

P(wrong answer) = 3/4

----

Since you want 4 correct of 20 we have a combination of 20C4

This is a binomial problem where p = 1/4, q = 3/4 and we get

(20 "choose" 4)*(probability correct)^(number correct)*(probability incorrect)^(number incorrect)

putting numbers in we get

(20c4)*(1/4)^4*(3/4)^16

This gives us

~ .189685
