MArishka [77]3 years ago

7 0

Answer:

Step-by-step explanation:

The center is at (0, -6) so the equation is:

(x - 0)^2 + ( y + 6)^2 = r^2

x^2 + (y + 6)^2 = r^2

r^2 = 11

Answer is x^2 + (y + 6)^2 = 11.

Find the value of x.

lutik1710 [3]

Answer:

#7 is x = 51

#8 is x = 9

Step-by-step explanation:

#7 walk-through

35 + 2x + 16 + 4x + 3 = 360

35 + 16 + 3 + 2x + 4x = 360

54 + 6x = 360

6x = 306

x = 51

#8 walk-through

6x + 2 = 56

6x = 54

x = 9

The ratio of 10 to pencil is 2/7 if you count 84 pencil how many pain would you expect to find

frosja888 [35]

How much pain would you find? hopefully none, since you'd have lots of pens and pencils :).

$\bf \cfrac{pens}{pencils}\qquad \cfrac{2}{7}\qquad 2:7\qquad \qquad \cfrac{\stackrel{pens}{p}}{\stackrel{pencils}{84}}=\cfrac{2}{7}\implies p=\cfrac{84\cdot 2}{7}$

Data on the oxide thickness of semiconductor wafers are as follows: 425, 431, 416, 419, 421, 436, 418, 410, 431, 433, 423, 426,

DanielleElmas [232]

Answer:

423

Step-by-step explanation:

The sample mean is a point estimate of the population mean.

Therefore a point estimate of the mean oxide thickness for all wafers in the population is the mean of the sample data on the oxide thickness of semiconductor wafers.

To calculate the sample mean, we sum all the sample data and divide by the sample size which is 24. We get 423.33 ≈423
