Answer: Required probability is 0.9772.

Step-by-step explanation:

Since we have given that

Mean = 99 inches

Standard deviation = 14 inches

It is normally distributed.

We need to find the probability that in a randomly selected year, the snowfall was less than 127 inches.

As we know that

z=\dfrac{X-\mu}{\sigma}

So, it becomes,

P(X

Hence, required probability is 0.9772.

Suppose 3/4 is a root of a polynomial equation. what does this tell us about the leading coefficient and the constant term in th
snow_tiger [21]

Answer:

Nothing new about leading coefficient. Definition says it can't be zero. It can always be made equal to one by dividing through.

Constant term cannot be zero unless a root is zero.


Step-by-step explanation:

x-3/4 = 0 has root 3/4 constant term -3/4


(x-3/4)(x-b) = 0 has roots 3/4 and b, constant term 3b/4 which is zero only if b is zero.


(x-3/4)(x-b)(x-c) = 0 has roots 3/4, b, c, constant term -3bc/4 which is zero only if b or c is zero.


Etc. ...

Irina18 [472]

Answer:

72°

Step-by-step explanation:

There are 5 blades, equally spaced.  So the angle between adjacent blades is 360° / 5 = 72°.  So you can rotate the fan 72° and the blades will align again.

gavmur [86]

Answer:

2\frac{4}{5}\ \ or \ 2.8 \ \ cups

Step-by-step explanation:

-The total portion fed to the dog is 7/10 cup

  • Canned-3/10
  • Dry=7/10-3/10=4/10

-One week has 7 days. we multiply the dry portion per day by the number of days in a week.

Dry= Total -Canned\\\\=\frac{7}{10}-\frac{3}{10}\\\\=0.40 \ cup\\\\Dry \ per \ Week= Dry/ day\times days\\\\=0.40\times 7\\\\=2\frac{4}{5}\  or\  2.8 \ cups

Hence, Erin feed her dog 2 4/5 0r 2.8 cups of dry food
