Answer:
The lateral area = 450 mm²
Step-by-step explanation:
The lateral area of any prism is equal to the areas of the sides faces
∵ The base of the prism is triangle
∴ It has 3 side faces
∵ The lengths of the side faces are 5 , 12 , 13 and their height is 15
∴ The lateral area = (5 × 15) + (12 × 15) + (13 × 15)
= 75 + 180 + 195 = 450 mm²
Answer:
3x+18
Step-by-step explanation:
Answer:
w = 6.9
Step-by-step explanation:
6.96 = 2.2(w − 5.1) + 3
6.96 = 2.2w - 11.22 + 3
6.96 = 2.2w - 8.22
collect like term
2.2w = 6.96 + 8.22
2.2w = 15.18
divide through by 2.2
w = 15.18/2.2
w = 6.9
Answer:
A. The mean value is greater than the median value
Step-by-step explanation:
The median is found by rearranging the numbers from least to greatest and is the number that separates the lower half from the upper half. In this case that number was 0.75. The mean however is found by averaging all the numbers: adding them all up and dividing by the number of numbers. When I did that for this set of terms I got 1.08. Seeing as 1.08>0.75, the mean of the set is greater than the median.
