Since we know that 1 foot is 12 inches, we can determine that a half of a foot is 6 inches. We have 7 feet, so we need to multiply 12 and 7 to find 7 feet in inches. 12*7 is 84, but we still have to add in our additional 6 inches. When we add 6 to 84, we get 90. Therefore, the classroom door is 90 inches tall.
A conclusion which can be derived from these random samples is that: B. the students in grades 11 and 12 scored higher than the students in grades 9 and 10.
<h3>What is a median?</h3>
A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.
Based on the information provided for these samples, we can logically conclude that the students in grades 11 and 12 scored higher than the students in grades 9 and 10 because a median score of 86 is greater than a median score of 79.

Answer:
10 m
Step-by-step explanation:
To get to the warehouse from the showroom, you could travel 8 metres to the right, and 6 metres up
But to find the shortest distance, find the hypotenuse
a² + b² = c² (To find the hypotenuse, the slanted side)
c stands for the shortest distance
a = 6 b = 8
6² + 8² = 36 + 64 = 100
Square root the 100 to get 10, an that is your length
