In this problem, we're going to use the 'PEMDAS' method.

First, we're doing the problem in the parenthesis.
44 - 4 = 40

Next in PEMDAS, we need to do the exponent.
6² = 6 x 6 = 36

Then we would do multiplication, but there is nothing to multiply so we move onto division.
40 / 2 = 20

Now we would add, but there is nothing to add so we move onto subtraction.
20 - 36 = -16

Our final answer would be -16.

Hope this helps!~

- A new rectangular lawn has a
disa [49]

The number of bags of grass seed that are needed to seed the new rectangular lawn is approximately 19 bags .

<h3>Perimeter of a rectangle</h3>

The perimeter of a rectangle is the sum of the whole sides of the rectangle.

Therefore,

perimeter of the rectangle = 298 ft

The width is 67 ft.

Hence

perimeter of rectangle = 2(l + w)

where

  • l  = length
  • w = width

Therefore,

298 = 2 ( l + 67)

298 = 2l + 134

298 - 134 = 2l

164 = 2l

l = 164 / 2

l = 82 ft

Therefore,

area of the rectangle = 82 × 67 = 5494 ft²

285 ft² = 1 bag of grass seed

5494 ft² = ?

cross multiply

number of bag of grass seed to fill the new rectangular lawn = 5494 / 285

number of bag of grass seed to fill the new rectangular lawn = 19.2771929825

the standard deviation of 100 random samples of the same size is approximated to be 0.98. what is the margin of error​
pogonyaev

Answer:

MOE= ± 0.098

Step-by-step explanation:

-The margin of error is calculated using the formula:

MOE=\pm \frac{\sigma}{\sqrt{n}}

#Substitute to solve for MOE:

MOE=\pm \frac{\sigma}{\sqrt{n}}\\\\=\frac{0.98}{\sqrt{100}}\\\\=\pm 0.098

Hence, the margin of error is ± 0.098
