Answer:

3 $\frac{4}{8}$ cups

Step-by-step explanation:

To subtract two fractions with different denominators easily, you can find the LCM of the denominators to make a simple subtraction problem.

LCM - Lowest Common Multiple

To find the LCM of two numbers, write down each numbers' times tables until they have a common number:

4 - 4, 8, 12, 16, 20,....

8 - 8, 16, 24, 32, 40,....

Because 8 is the first number to be in both numbers' multiples, it is the LCM of 4 and 8.

Now that the LCM has been determined, you need both denominators to be 8. This is an easy process as it is simple multiplication:

3 $\frac{1}{4}$ → $\frac{1}{4}$ × $\frac{2}{2}$ = $\frac{2}{8}$

6 $\frac{6}{8}$ → no multiplication needed.

Now to subtract:

6 $\frac{6}{8}$ - 3 $\frac{2}{8}$ = 3 $\frac{4}{8}$

Because the question does not want a simplified fraction, the final answer is 3 $\frac{4}{8}$ cups.

Can a function have a y-value with more than one x value why or why not ?

No because x can only repeat two times. After that it is no longer a proper function

Suppose that the probability density function ofthe length of computer cables is f (x) = 0.1 from 1200 to1210 millimeters.a. Det

Ann [662]

Notice that $f(x)=0.1$ for $1200\le x\le1210$ implies that $f(x)=0$ elsewhere, since

$\displaystyle\int_{1200}^{1210}f(x)\,\mathrm dx=1$

where $X=x$ is a random variable representing cable lengths according to the PDF $f(x)$ .

a. By definition of expectation, the mean is

$E[X]=\displaystyle\int_{-\infty}^\infty x\,f(x)\,\mathrm dx=0.1\int_{1200}^{1210}x\,\mathrm dx=1205$

The variance is

$\operatorname{Var}[X]=E[(X-E[X])^2]=E[X^2]-E[X]^2$

where

$E[X^2]=\displaystyle\int_{-\infty}^\infty x^2\,f(x)\,\mathrm dx=0.1\int_{1200}^{1210}x^2\,\mathrm dx=\frac{4,356,100}3$

so that the variance is $\frac{25}3$ , making the standard deviation $\frac5{\sqrt3}$ .

b. The proportion of cables within specs is

$P(1195$

Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the s

Furkat [3]

Answer:

$\frac{16\pi}{3}$ .

Step-by-step explanation:

I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = $4x-x^{2}$ . The shaded region in blue is the region we are going to rotate.

Now, to find the volume v= $2\pi \int\limits^a_b {p(x)h(x)} \, dx$ where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= $4x-x^{2}-3$ . Then,
