-16x +17

Step-by-step explanation:

1 . (4x² - 9x + 16) + (7 + 9x² - 10x)

4x² - 9x + 16 + 7 + 9x² - 10x

13x² - 19x + 23

2 . (-2x + 6) - (14x - 11)

-2x + 6 - 14x + 11

-16x +17

Sixty percent of the students at a certain school wear neither a ring nor a necklace. Twenty percent wear a ring and 30 percent

Reptile [31]

Answer:

0.4

Step-by-step explanation:

Given

60 % wear neither ring nor a necklace

20 % wear a ring

30 % wear necklace

This question can be Solved by using Venn diagram

If one person is choosen randomly among the given student the probability that this student is wearing a ring or necklace is

$P\left ( wear \ ring\ or \ necklace )+P\left ( neither\ ring\ or\ necklace)=1$

$P\left ( wear \ ring\ or\ necklace )=1-0.6=0.4$

The sum of probabilty is equal to 1 because it completes the set

Therefore the required probabilty is 0.4

Which of the following functions results in a graph that shows exponential decay? f(x) = 4(0.8)x f(x) = 0.7(1.2)x f(x) = 12(3)x

Korvikt [17]

The function will show exponential decay if one of the following is true

the base is less than 1 and the exponent is positive
the base is greater than 1 and the exponent is negative

The function that meets the requirement for exponential decay is ...

$f(x)=4\cdot 0.8^{x}\quad\text{matches the first choice}$
