Answer:

 Nevan won the game.

 He scored 183 points.

Explanation:

  Correct answer is worth 13/4 points

  Incorrect answer is worth -1/4 points.

  Number of correct answers = 58

  Number of incorrect answers = 22

  Point scored =58*\frac{13}{4} +22*\frac{-1}{4} =\frac{732}{4} =183

  Points need to win = 90 points

  Point scored, 183 >Points need to win, 90

  So, Nevan won the game.

A survey of 285 adults found that during the last year, 75 traveled by plane but not by train, 55 traveled by train but not by p
meriva

Answer:

40

Step-by-step explanation:

Given that

Total number of adults, U = 285

Number of plane travellers, P = 75

Number of train travellers, T = 55

To find the number of people that didn't travel by any means of transportation listed in the question, then we say

Total number of adults minus number people who traveled by plane or train minus number of people who traveled by bus but not by plane or train.

This means that number of people who didn't travel by any of the three means of transportation, N =

N = U - pt - b

N = 285 - 215 - 30

N = 40

Therefore, the total number needed is 40

What is the sum of the arithmetic series 18 t=1 (3t-4)
PolarNik [594]

Consider the arithmetic series _{t=1}\Sigma^{t=18} (3t-4)

Let t=1 in the given series, we get

first term = a_{1} = 3-4 = -1.

Let t=2 in the given series, we get

second term = a_{2} = (3 \times 2)-4 = 2

Let t=3 in the given series, we get

third term = a_{3} = (3 \times 3)-4=5

Now, let t=18 in the given series, we get

last term = l = l = (3 \times 18)-4 = 50

We get the series as

-1, 2, 5,..... 50

Sum = \frac{n}{2}(a+l)

= \frac{18}{2}(-1+50)

= = 9 \times 49

= 441

Therefore, the sum of the given arithmetic series is 441.
