<span>A </span>continuity correction factor<span> is used when you use a continuous function to approximate a discrete one. For example, when you want to approximate a binomial with a </span>normal distribution<span>. According to the </span>Central Limit Theorem<span>, the </span>sample mean<span> <span>of a distribution becomes approximately normal if the </span></span>sample size<span> <span>is large enough. The </span></span><span>binomial distribution </span><span>can be approximated with a </span>normal distribution<span> too, as long as n*p and n*q are both at least 5. So the answer is large</span>

This is exponential growth function


y=4(2)^x

X                4(2)^ x             Y

0                 4(2)^0             4

1                  4(2)^1              8

2                 4(2)^2             16

1/2               4(2)^(1/2)        1.4

Which expression is equivalent to |b| &gt;2?
vovangra [49]

Answer:

The equivalent expression for |b| > 2 is {b : b < -2} ∪ {b : b > 2}.

Step-by-step explanation:

The expression |x| < a is equivalent to -a < x < a and the expression |x| > a is equivalent to {x : x < -a} ∪ {x : x > a}.

This means, the set of all points that satisfy the inequality |x| < a is the set of all points between -a and a exclusive of -a and a.

The set of all points that satisfy the inequality |x| > a is the set of all points that are less than -a and the set of all points that are greater than a.

Hence, the equivalent expression for |b| > 2 is {b : b < -2} ∪ {b : b > 2}.

Will give brainliest. Pls help. The volume of a cylinder is 300 feet^3. Find the volume of a cone and a sphere that have the sam
USPshnik [31]

Answer:

Cone: 100ft^3

Sphere: 200ft^2

Step-by-step explanation:

Firstly, the volume of a cone is 1/3 of the volume of the cylinder. It's literally in the formula:

V_{cone} = \frac{h \pi r^2}{3}\\\textrm{As you can notice, }\pi r^2\textrm{ is the area of the base, like in the cylinder formula}\\

So we can just instantly tell that the volume of the cone is 100feet^3.

Not for the sphere - we can assume that if the height is the same, it's equal to two radiuses, or simply - to the diameter. Let's use the formula for the volume of a sphere, but substitute one of the radiuses with \frac{h}{2}

V_{sphere} = \frac{4\pi r^3}{3} = \frac{2\pi r^2 h}{3} = \frac{2h\pi r^2}{3} = 2\cdot V_{cone}

So we can instantly tell that the volume of the sphere is 200feet^3
