Answer:
1/4 or 25% chance
Step-by-step explanation:
the probability of getting each question right is 1/2, so for getting 2 questions right its 1/2 × 1/2, which is 1/4
Answer:
6c^4 - 2c^3 + 4
Step-by-step explanation:
- (4c^4 + 1) - (7c^3 - 3) + (2c^4 + 5c^3) = ⇒ parenthesis
- 4c^4 + 1 - 7c^3 + 3 + 2c^4 + 5c^3 = ⇒ simplify, add up like terms
- 6c^4 - 2c^3 + 4 ⇒ answer
Answer:the answer is 5/2 because if yo subtract y2 from y1 and x2 from y2 thats the answer you get.
But you might not get that answer straight away you need to simplify the initial value and keep going until you cant simplify without a remainder.
Step-by-step explanation:
Answer:
w = 6.9
Step-by-step explanation:
6.96 = 2.2(w − 5.1) + 3
6.96 = 2.2w - 11.22 + 3
6.96 = 2.2w - 8.22
collect like term
2.2w = 6.96 + 8.22
2.2w = 15.18
divide through by 2.2
w = 15.18/2.2
w = 6.9
