What is the value of (33 - 2 × 7) + (5 × 3 - 22) ?

12

Step-by-step explanation:

Keep in mind the rules of PEMDAS

P (parenthesis)

E (exponents)

M (multiply)

D (division)

A (addition)

S (subtraction)

Because parenthesis is the first operation in PEMDAS, you would start by calculating inside the parenthesis

We can start with the numbers inside the first parenthesis

(33 - 2 × 7)

Start by multiplying 2 and 7 because the M comes before the S

(33 - 2×7)= (33- 14)

Now subtract 14 from 33

(33-14) = 19

Step 2: Calculate inside the second parenthesis

(5 × 3 - 22)

Multiply first

(5 × 3 - 22)= (15 - 22)

Subtract!

(15 - 22)= -7

Now add the final number together

(why? There is an addition sign between the two parenthesis ordering us to add the final numbers together)

19 + (-7)

19-7

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
