Answer:

A

Step-by-step explanation:

[tex]V = \frac{nd^2h}{6}[/tex]

multiply both sides by 6

[tex]6V = nd^2h[/tex]

divide both sides by [tex]nd^2[/tex]

[tex]\frac{6V}{nd^2} = h[/tex]

So the answer is A.

Answer:

y = 6

Step-by-step explanation:

3y/2 - 1 = 8

3y/2 = 8 + 1

3y/2 = 9

3y = 9 × 2

3y = 18

y = 18/3

y = 6

Answer:

y = 6

Step-by-step explanation:

[tex]\frac{3y}{2}[/tex] -1 =8

[tex]\frac{3y}{2}[/tex] -1 + 1 =8 +1

[tex]\frac{3y}{2}[/tex] = 9

[tex]\frac{3y}{2}[/tex] × 2 = 9 × 2

3y = 18

3y/3 = 18/3

y = 6

Double check:

[tex]\frac{3(6)}{2}[/tex] - 1 = 8

[tex]\frac{18}{2}[/tex] -1 =8

9 - 1 = 8

8 = 8

Suppose the value of Young's modulus (GPa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations.

116.8 115.7 114.9 115.4 115.9

Required:
a. Calculate the deviations from the mean.
b. Use the deviations calculated in part (a) to obtain the sample variance (in GPa2).

Answers

Answer:

a) The deviations from the mean

|x-x⁻|  :   1.06       |-0.04 |       |-0.84 |     |-0.34 |     | 0.16  |  

b)

The variance of the sample      S² = 0.493

The standard deviation of the sample  S =√0.493 = 0.7021

Step-by-step explanation:

Step(i):-

Given that the sample observations

   x   :    116.8       115.7     114.9     115.4     115.9

Mean of the sample

                       = ∑ x/n

 Mean of sample x⁻  = [tex]\frac{116.8+115.7+114.9+115.4+115.9}{5}[/tex]

 Mean of sample x⁻ = 115.74        

Step(ii):-    

The deviations from the mean

|x-x⁻|  :  116.8-115.74       115.7-115.74   114.9-115.74  115.4-115.74   115.9-115.74

|x-x⁻|  :   1.06                 |-0.04 |               |-0.84 |         |-0.34 |             | 0.16  |  

|x-x⁻||²:    1.1236             0.0016             0.7056          0.1156             0.0256

The variance of the given sample observations

          S²  = ∑ (x-x⁻)² / n-1

         [tex]S^{2} = \frac{1.1236+0.0016+0.7056+0.1156+0.0256}{5-1} = 0.493[/tex]

The variance of the sample      S² = 0.493

The standard deviation of the sample  S =√0.493 = 0.7021

Answer:

D. x+2y=12

Step-by-step explanation:

From the graph we know that the y-intercept is 6. (0,6) and the x-intercept is 12. (12,0)

The graph is going down so the slope is negative, from (0,6) count down to (0,0) and count right 12 unit to reach the x-intercept(12,0) the slope is -6/12 or -1/2.

the equation of the line is y=-1/2+6 or x+2y=12

x+2y=12

2y=-x+12

y=-1/2x+6

Answers

Answer:

Company A is 1.99 times B.

Step-by-step explanation:

Company A charges:

[tex]A=70.50+0.50=\$71/mile[/tex]  

Company B charges:

[tex]B=35.50+0.09=\$35.59/mile[/tex]

We just need to divide A by B:

[tex]x=A/B=1.99[/tex]

Therefore, company A is 1.99 times B.

5. Cuando abrió sus puertas, una tienda de café ofrecía 6 tipos diferentes de
bocadillos. Desde entonces, agregó dos nuevos bocadillos cada semana.
Si la tienda ofrece ahora 28 bocadillos diferentes, ¿cuántas semanas (s) han
transcurrido desde su inauguración?
?

Answers

Answer:

11 weeks have passed.

Step-by-step explanation:

We can create a linear function that represents the number of bocadillos offered as a function of the number of weeks (s) that went by since the beginning (when the number of bocadillos was 6):

f(s) = 6 + 2 * s

Since now the number of bocadillos is 28, we can solve for s in the equation

28 = 6 + 2 * s

subtract 6 from both sides

28 - 6 = 2 * s

22 = 2 * s

divide both sides by 2

11 = s

Therefore, 11 weeks have passed.

Step-by-step explanation:

Step-by-step explanation:

step 1. a function must only have a single y value for each x value.

step 2. for the input x, there can only be one output or result y.

step 3. #1 is a function because for each x there is only one y.

step 4. #2 and #3 are functions also.

step 5. #4 is not a function because (1, 1) and (1, -1) says x is 1 but the y is both 1 and -1 (2 values)

step 6. (2, 2) and (2, -2) also makes #4 not a function.
