Answer:
28.729%
Step-by-step explanation:
The yield percentage is found from ...
((end value) -(start value))/(start value) × 100%
= (18434 -14320)/14320 × 100%
= 4114/14320 × 100% ≈ 28.729%
Supriya's investment had an effective yield of 28.729%.
Answer:
110
Step-by-step explanation:
you would have to place the values in a line in ascending order and cancel numbers on both sides until you only have one left in the center. If you have two left because the number of variables is even then add both and divide by two. That was the case here. Both middle numbers were 110
so...
110+110/2
220/2
110
Answer:
Step-by-step explanation:
1+1=2
(70+71+72+x)/4 is greater than or equal to 73
the average is all of the plants divided by the number of plants, which is 4. we don't know what the other plant has to be, so it is called x. The average has to be at least 73, so greater than or equal to 73
add them up to get (213 + x)/4 is greater than or equal to 73. then divide 213 and x separately by 4 to get 1/4x + 53.25 is greater than or equal to 73. subtract 53.25 from both sides to get 1/4x is greater than or equal to 19.75 then divide both sides by 1/4 to get x is greater than or equal to 79
