Answer:
The mean will reduce
Step-by-step explanation:
The total amount of money for the ten days divided by number of days will give mean 1, M₁
Removing the value for day seven will reduce the sum of money as it will be for 9 days only.In finding the mean, you will divide by 9 days to get mean M₂
Mean M₂ < M₁
Answer:
The length of the garden is 94 m.
Step-by-step explanation:
you do 5828 m. divided by 62m. and that is how you get your answer of 94 m.
Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
64 = 4x + 8
4x = 56
x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm
Answer:
width = 14 cm
length = 50 cm
