TEA [102]

Answer:

$310

Step-by-step explanation:

The first step is to add the costs of the textbook together :

$68.41 + $105.35 + $72.49 + $59.91 = $306.16

In order to round off to the nearest ten dollars, look at the units figure, if the number is greater or equal to 5, add 1 to the ten figure. If this is not the case, add zero. Replace the unit digit with zero

The unit digit is greater than 6, so 1 is added to the tens digit. The amount becomes $310

Arturiano [62]

Answer:

The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)

Step-by-step explanation:

Mean m = 400

Standard deviation S = 60

Firstly, we have to determine the cut off mark,

Since Only students who score in the top 30% are accepted, the cut off mark can be determined from 70% of the mark.

P(cut off mark = X) = Z[( X -m)/S) <x]

=¢(X-400/60) = 0.7

From Normal distribution table,

X-400/60 = 0.524

X = 431.44

Therefore, the cut off mark is 431.44

Since Amy scores 425 on the test.

Therefore, The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
