50 question true-false final exam (two-points each question) and you never paid attention in the class (or knew anything about t

Title:

<h2>Check the explanation.</h2>

Step-by-step explanation:

As all the questions of the exam carry 2 points, at least $\frac{56}{2} = 28$ questions need to be correct to get 56 marks.

In order to get a maximum of 56 marks, at most 28 answers needs to be correct.

Every question has two option. Hence, the probability of getting a particular question right is $\frac{1}{2}$ .

The probability that exactly n questions will be right is $^{50}C_n (\frac{1}{2} )^n (\frac{1}{2} )^{50 - n} = ^{50}C_n (\frac{1}{2} )^{50}$ .

The probability that at most 28 questions will be right is ∑ $^{50}C_n (\frac{1}{2} )^{50}$ , $0\leq n\leq 28$ .

Similarly, the probability that at least 30 questions will be right is ∑ $^{50}C_n (\frac{1}{2} )^{50}$ , $30\leq n \leq 50$ .

Two cars started from the same point and traveled on a straight course in opposite directions for exactly 2 hours, at which time

OlgaM077 [116]

Answer with Step-by-step explanation:

Let speed of one car=x miles/h

Speed of second car=x+8 mi/h

Time,t=2 hours

Distance between two cars=208 miles

We have to find the average speed for each car for 2-hour trip.

Distance= $Speed\times time$

Distance traveled by one car=2x

Distance traveled by second car=2(x+8)

According to question

$2x+2(x+8)=208$

$2x+2x+16=208$

$4x=208-16$

$4x=192$

$x=\frac{192}{4}=48$

Speed of one car=48mph

Speed of second car=48+8=56mph
