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.

The equation y = 155x + 110, 419 approximates the total cost in dollars, of raising a child in the United States from birth to 1

faust18 [17]

Answer: Third option.

Step-by-step explanation:

According to the information given in the exercise, you can find an approximation of the the total cost in dollars of raising a child in the United States ( from birth to 17 years) given a household's annual income, with the following equation:

$y = 1.55x + 110, 419$

Where "x" represents the household's annual income in dollars.

Therefore, if the annual income is $62,500; you can identify that:

$x=62 ,500$

Then, in order to calculat the approximated cost to raise a child in a household with that annual income given in the exercise, you need to substitute that value of "x" into the equation and then you must evaluate in order to find the value of "y".

Through this procedure you get the following result:

$y = 1.55(62 ,500) + 110, 419\\\\y=96,875+ 110, 419\\\\y=207,294$
