Answer: The perimeter is 126.

Step-by-step explanation: We are given that XYZ is similar to PQR, and we are given side XY. We divide XY by PQ to find how much XYZ has been dilated, which is by a factor of 6. Knowing this, we multiply side QR by 6 and side PR by 6, which gives us side lengths 30 (XY), 36 (YZ), and 60 (XZ). Adding these up gives us 126 :)

charle [14.2K]

Answer:

Step-by-step explanation:

a)

Confidence interval in less than symbol expressed as

$\bar{x} - E < \mu < \bar{x} + E
$

Where $\bar{x}$ is sample mean and $E$ is margin of error.

$13.03 < \mu 13.42
$

b)

The given t interval is $(13.032 , 13.418 )
$

That is $\bar{x} - E = 13.032$ and $\bar{x} + E = 13.418$

Solve these two equation by adding together.

$2 \bar{x} = 13.032 + 13.418
\\\\\bar{x} = 13.225$

Solve this value of \bar{x} in equation $\bar{x} - E = 13.032$ and solve for $E$

$13.225 - E = 13.032
\\\\E = 0.193
$

Best point estimate of $\mu = \bar{x} = 13.225
$

Best point estimate of margin of error = 0.193

c)

Since sample size = 100 which is sufficiently large (Greater than 30) , it is no need to confirm that

sample data appear to be form a population with normal distribution.

I want the answer to this problem<br> 3(x+2)-x=38

maks197457 [2]

Answer:

x = 16

Step-by-step explanation:

3(x+2)-x=38

Distribute

3x+6 -x = 38

Combine like terms

2x+6 = 38

Subtract 6 from each side

2x+6-6 = 38-6

2x = 32

Divide each side by 2

2x/2 = 32/2

x = 16
