valentinak56 [21]2 years ago
4 0

Answer:

Step-by-step explanation:

1. y= 1-x² is quadratic because has the variable x to the second power

y = -x² +1 has quadratic term -x², and constant term is 1

2. y= 3x-5 +4x²

a. quadratic term is 4x² because has the variable x to the second power

b. linear term is 3x because has the variable x to the power of one

c. constant term is -5 because the variable x to the power 0 so there is no x

Ksenya-84 [330]

Answer:

Proved,

P(A∪B)=0.72

Step-by-step explanation:

Sue travels by bus or walks when she visits the shops.

Probability( catch the bus to the shop ), P(A) = 0.4

Probability( catch the bus from the shop ), P(B) = 0.7

Both A and B are independent events.

Therefore,

P(A∩B) = 0.4×0.7

           = 0.28

Probability Sue walks one way = 1 - P(A∩B)

                                                   = 1 - 0.28

                                                   = 0.72

Hence, the probability that Sue walks at one way is 0.72

A number is randomly selected from {80, 81, 82, 83, 84, 85, 86}.
Ivan
The probability that the number picked is less than 84 p(A) is:
number of possible events with picked number less than 84/ total number of possible events = 4/7
The complement event of A is that event A does not occur. If the picked number is not less than 84 ( this means is greater than 84 or is 84). The probability of the complement event is:1- p(A)=3/7

Solution: B
