Those 16 problems cost him 34%

One problem is worth 34/16 = 2.0625

So each question is worth about 2 point.

2*x = 66 Divide by 2

x = 66 /2 = 33 questions that he got right.

The total number of questions is 33 + 16 = 49

Does the rounding really matter?

2.0625 x = 66

x = 66/2.0625

x = 32 yes it matters.

Total number of questions = 32 + 16 = 48 <<<< answer.

andrew11 [14]

Answer:

Step-by-step explanation:

Given that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"†).

a) $P(X\leq 15) = 0.1565=0.157$

b) $P(X>26) =1-F(26)\\= 1-0.9221\\=0.0779=0.078$

c) $P(15\leq x\leq 26)\\=F(26)-F(14)\\=0.9221-0.1049\\=0.8172=0.817$

d) 2 std dev = 2(20) =40

Hence 2 std deviation means

20-40, 20+40

i.e. (0,60)

$P(0$

2y to the 2nd power +11y +14

goldfiish [28.3K]

$2y^2 +11y+14$ $=(2y+7)(y+2)$

Step-by-step explanation:

Given

$2y^2 +11y+14$

$=2y^2 +(7+4)y+14$

$=2y^2+7y+4y+14$

$= y(2y+7) + 2(2y+7)$

$=(2y+7)(y+2)$
