Hello,

1) the line parallele to ox passing by (1,4) has for equation y=4

f(x)=4 if -1<=x<=1

2) the line pasing through (3,2) and (5,4) has for equation:

y-2=(4-2)/(5-3)(x-3)
==>y=x-3+2
==>y=x-1

f(x)=x-1 if 3<=x<=5.

Using remainder theorem find the remainder when p(x) = 3x^3 - 4x^2 - 5x +11 divided by ( x + 1)

DedPeter [7]

Answer:

Step-by-step explanation:

The remainder is given by the value of f(-1):

Remainder = 3(-1)^3 - 4(-1)^2 - 5(-1) + 11

= -3 - 4 + 5 + 11

= -7 + 16

= 9.

Jean adds 35 and 9. How can she solve using only equations to model her thinking?

mina [271]

Since she only has a two digit number and a one digit number she will be able to create one or two equations.

35+9=44
Or she may want to break up the two digit number into two or more parts, for example: (5×6) + (1×5) + 9 = 44 or (7×5) + 9 = 44

A bookbook can be classified as either non dash fictionnon-fiction or fictionfiction. Suppose that 9494% of booksbooks are clas

DIA [1.3K]

Answer:

a) 0.8836

b) 0.7339

c) 0.2342

Step-by-step explanation:

Books classified as fiction = 94% or 0.94 probability

Books classified as non-fiction = 1 - 0.94 = 0.06

a) for two books, we get: 0.94 * 0.94 = 0.8836 Probability

b) The probability that all five books are fiction is: 0.94^5

This equals 0.7339 Probability

c) Probability that one books is non-fiction, while the other 4 are fiction is determined in the following way:

Probability of non-fiction * probability of fiction^(number of books)

0.06 * 0.94^4 = 0.0468

This does not account for the order at which the non-fiction book shows up. Such as the non-fiction book being the first book picked, or in another case - the non-fiction book being the last picked.

Since there are 5 ways this could occur, the total probability will be calculated as shown: 0.0468 * 5 = 0.2342 Probability
