Answer:

<h2>9498.5 m</h2>

Step-by-step explanation:

We know that the Circumference = 3454 cm

And we also know that the formula for the Circumference of Circle is,

2\pi \times r

So we can put the equation this way,

3454 = 2\pi \times r

So we can solve for 'r'

3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r   =   \frac{3454}{6.28}  \\ r = 550

Now we have radius and we can solve for the area of the circle,

\pi \times  {r}^{2}

3.14 \times 550 \times 550  \\  = 949850

We can convert this to meter,

9498.5 m

I am not sure if this is correct just let me know thanks :)

Use the expression 28b - 4c. Part B: What is the value of the expression when b = -4 and c = 1? Show your work or explain.
Brilliant_brown [7]

Answer:

The value of the expression is -116

Step-by-step explanation:

Given

Expression: 28b - 4c

Required

Solve when b = -4 and c = 1

Expression: 28b - 4c

Substitute -4 for b and 1 for c

Expression: 28*-4 - 4*1

Expression = -28*4 - 4

Expression = =112 - 4

Expression: -116

<em>The value of the expression is -116</em>

n HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you tha
Dominik [7]

Answer:

0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 17.39 ppm

Standard Deviation, σ = 4.25 ppm

Sample size = 11

We are given that the distribution of printing speed is a bell shaped distribution that is a normal distribution.

Formula:  

z_{score} = \displaystyle\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}  

P(printing speed of the sample is greater than 17.99 ppm.)  

P(x > 17.99)  

P( x > 17.99) = P( z > \displaystyle\frac{17.99-17.39}{\frac{4.25}{\sqrt{11}}}) = P(z > 0.468229)\\\\P( z > 0.468229) = 1 - P(z < 0.468229)

Calculating the value from the standard normal table we have,

1 - 0.679 = 0321= 32.1\%\\P( x > 17.99) = 32.1\%

Thus, 0.321 is the probability that their mean printing speed of the sample is greater than 17.99 ppm.
