Question

measurement
andrea is buying a rectangular rug that is 3 feet wide by 4 feet long.
what is the total area that the rug will cover?
a) 12 square feet
b) 14 square feet
c) 24 square feet
d) 28 square feet

if you have a triangle and one angle is 60 degrees and the second angle is 90 degrees, what is the measurement of the third angle?

statistics
the 5th grade students received the following scores on their spelling test
88, 83, 98, 65, 76, 92

determine the following:
mean______
median______
mode______
range______

Explanation:

Step1: Calculate rug area

Area = length × width = $4 \times 3 = 12$ square feet

Step2: Find third triangle angle

Sum of angles = 180°, so $180 - 90 - 60 = 30$ degrees

Step3: Calculate test score mean

Sum scores, divide by count: $\frac{88+83+98+65+76+92}{6} = \frac{502}{6} \approx 83.67$

Step4: Calculate test score median

Order scores: 65,76,83,88,92,98. Average middle 2: $\frac{83+88}{2} = 85.5$

Step5: Identify test score mode

No repeated scores, so no mode

Step6: Calculate test score range

Max - min = $98 - 65 = 33$

Answer:

1. a) 12 square feet
2. 30 degrees
3. Mean: $\approx 83.67$

Median: $85.5$
Mode: None (no repeated values)
Range: $33$
