A​ student's course grade is based on one midterm that counts as 5​% of his final​ grade, one class project that counts as 25​%
Mumz [18]

Answer:

His overal final score is 81.2. His letter grade is a B.

Step-by-step explanation:

Weighed average:

The sum of all values multiplied by it's weight. The weight is a proportion(a value between 0 and 1).

So.

Score of 72 on the midterm, which counts 5%.

Score of 83 on the project score, which counts 25%.

Score of 91 on homework assignments, which counts 35%.

Score of 74 on the final exam, which counts 35%.

His grade is:

G = 72*0.05 + 83*0.25 + 91*0.35 + 74*0.35 = 82.1.

His overal final score is 81.2.

At least 80 but less than 90 is a​ B

So his letter grade is a B.

Sveta_85 [38]

Answer:

<u>Usain Bolt's average speed in yards per second was 11.4</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

World record of Usain Bolt = 9.589 seconds

Distance of the world record = 100 meters

1 yard = 0.9144 meters ⇒ 100 meters = 109.36 yards

2. What was Usain Bolt's average speed in yards per second?

Let's recall that the formula of speed is:

Speed = Distance/Time

Replacing with the values we know:

Usain Bolt's Speed = 109.36/9.589

<u>Usain Bolt's Speed = 11.4 yards per second (Rounding to one decimal place)</u>
