➷ Standard deviation = \sqrt{(n*p)(1 - p)}

Substitute the values in:

\sqrt{(500 *0.84)(1-0.84)} = 8.1975...

This can be rounded to give an approximate answer of 8.2

The answer is option A.

What number will the function return if the input is 15.4?
wlad13 [49]

The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.

So, if the input is 15.4, the output will be

f(x)=3x \implies f(15.4)=3\cdot 15.4 = 46.2

HELP ASAP PLS.
Sindrei [870]

Step-by-step explanation:

I have no idea if I'm doing it right but my guess would be to take the values that we get from f(x) and g(x) when x = 1.  Therefore we get that f(x) is equal to 4 and g(x) is equal to -1.  We than just do f/g which is 4/-1 which gives us the final answer of -4 which is option B.

Answer:  Option B, -4

0.85 in fractional notation
artcher [175]
If you would like to write 0.85 in a fractional notation, you can do this using the following steps:

0.85 = 85/100 which simplifies to 17/20 <span>(the common factor of 85 and 100 is 5, so you can divide both numbers by 5).

The correct result would be 17/20.</span>

The radius r and height h of a right circular cone are both increasing at a constant rate of 2 cm/h. At what rate in centimeters
Elden [556K]

Answer:

94.2

Step-by-step explanation:

i honestly dont know if this answer is right but i am currently takeing classes in math about Geometry. We was learning about Word problems, that had to do with volume, Area, and perimeter, and learned what radius is, etc..

  • So i thought you take the formula it gives you and use. Since Pie means 3.14 you use that in the formula. V= 1×3.14×2×15 = 94.2
  • you would multiply everything together because every number is close together.
  • the height is 15 cm, thats how you get 15 at the end.
  • next step is to solve the equation in your calculator. and it gives you that number. = 94.2
