Answer: 9c^3d^2(6d^2+c)

Step-by-step explanation:

Given expression : 54c^3d^4+9c^4d^2

We can write the above expression as

(6\times9)c^3d^{(2+2)}+9c^{(3+1)}d^2

=(6\times9)c^3d^2d^2+9c^3c^1d^2

We can see the greatest common factor of both the terms = 9c^3d^2

Taking the greatest common factor outside , we get

9c^3d^2(6d^2+c)

Hence, the factorize form of given expression is given by:-

54c^3d^4+9c^4d^2=9c^3d^2(6d^2+c)

wolverine [178]

Answer:

As the sample size increases, the variability decreases.

Step-by-step explanation:

Variability is the measure of actual entries from mean.  The less the deviations the less would be the variance.

For a sample  of size n, we have by central limit theorem the mean of sample follows a normal distribution for random samples of large size.

X bar will have std deviation as \frac{s}{\sqrt{n} }

where s is the square root of variance of sample

Thus we find the variability denoted by std deviation is inversely proportion of square root of sample size.

Hence as sample size increases, std error decreases.

As the sample size increases, the variability decreases.

Amanda leaned a 15-foot ladder against the top of her house so she could get on the roof, which is 12 feet from the ground.
valentinak56 [21]

If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)

a²+b²=c²

12²+b²=15²

144+b²=225

b²=81

√b²=√81

b=9

Triss [41]

The distance covered by the motorcycle is 31.4 km and displacement will be equal to 0.

<h3>What is Distance and Displacement ?</h3>

Distance and Displacement both are the measure of the movement of an Object from one point to another.

Distance is a scalar quantity while Displacement is a vector quantity , and so it depends upon direction.

Distance travelled will always be positive but Displacement can be positive , negative and zero.

A motorcycle rides from point P to Q to R to S and finally to P in a circular path as shown in the below figure

The missing figure is attached with the answer.

(a) The distance covered by the motorcycle is

2πr = 2 * 3.14 * 5 = 31.4 km

(b) The displacement will be equal to 0 as the starting and the ending point is same.
