Answer:

21cm^{3}

Step-by-step explanation:

According to the problem, calculation of given data are as follows,

Volume of cylindrical vase = 63cm^{3}

As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,

Volume of cone = \frac{1}{3} × Volume of cylindrical vase

By putting the value, we get

Volume of cone = \frac{1}{3} × 63

Volume of cone = 21cm^{3}

A person gets on and off a bathroom scale four times. The four readings (in pounds) are 148, 151, 150, and 152. Each time after
Ganezh [65]

Answer:

See explanation below

Step-by-step explanation:

Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of

148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25

We could estimate the uncertainty as <em>the standard error SE </em>

\bf SE=\frac{s}{\sqrt{n}}  

where  

<em>s = standard deviation of the sample </em>

<em>n = 4 sample size. </em>

Computing s:

\bf s=\sqrt{\frac{(146-148.25)^2+(149-148.25)^2+(148-148.25)^2+(150-148.25)^2}{4}}=1.479

So, the uncertainty is 1.479/2 = 0.736

<em>It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight. </em>

Maria Louisa looks at a sequence of shapes and records the number of vertices in each of the shapes in the sequence. The first s
seropon [69]

Step-by-step explanation:

arithmetic sequence.

an = an-1 + c = a1 + (n-1)c

c is in our case 2 (every new shape has 2 more vertices).

we have a a1 = 3.

an = 3 + 2(n-1)

so,

a21 = 3 + 2(20) = 3 + 40 = 43

the 21st shadow will have 43 vertices.

Answer:

-4y/3

Step-by-step explanation:

If we have -4xy/3x, we just cancel the x since it is in the numerator and denominator. That leaves us with just -4y/3
