Answer:
1. Yes
2. No
Step-by-step explanation:
You can have a case such as 26,30,30,30,30 and another case : of 4,40,40,32,8 satisfying the 2 statements at the same time but in the 2nd case, the average that is less than 28.
From the given statements combined together, to get e-a=4. So once you get this information, you can have a big range of values that may or may not have average >28.
Length - 14 meters
Width - 7 meters
The length is twice the width - 7 times 2 = 14
There are four sides, two 14m and two 7m. 14 x 2 + 7 x 2 = 42
63
.10d + .05n = 5.25
.10(21) + .05n = 5.25
2.1 + .05n = 5.25
.05n = 3.15
n = 3.15/.05
n = 63
Answer:
9
Step-by-step explanation:
(15×4+3)/4 ÷(4×1+3)/4= 63/4 ÷ 7/4= 9
