Answer:
The answer is 71.61%.
Step-by-step explanation:
Households discarding paper week is given to be normally distributed with a mean,
= 9.4 lb.
The normally distributed distribution has a standard deviation given as
= 4.2 lb.
The proportion of households that throw out at least 7 lb of paper a week is to be found.
Therefore we have to find p(X ≥ 7) which can be written as
p(X ≥ 7) = 1 - p(X < 7)
= 1 - p( Z <
)
= 1 - p( Z <
)
= 1 - p( Z < -0.571 )
= 1 - 0.2839
= 0.7161
Therefore the percentage of households that throw out at least 7 lb paper a week is 71.61%
A^2+b^2= c^2
Plug in the points. the longest side is always c.
95.2^2+ b^2= 168^2.
Square the numbers.
9063.04+ b^2= 28224
Subtract 9063.04 on both sides.
b^2= 19160.96
Find the square root.
b= 138.423119456
Or, b= 138.4 (rounded down)
I hope this helps!

Answer:
126 square meters
Step-by-step explanation:
7 x 6 x 3. You can regroup any pair of factors to make it easier on you.
I did (7 x 6) x 3 = 42 x 3 = 126
The answer would be option C) p= 6.25h. If you plug in h (hours worked) and multiply it by 6.25 it will equal p (pay).
Ex. p= 6.25(2) would result in the answer p= $12.50.
Since you want to round to the 10,000 place, you'll want to look at the 2 and the 8 that are next to each other. The 8 makes the two a 3 because it is greater than 5, which gives you 3,430,000. Hope this helped!
