If the mean = 54, 1 standard deviation (+1σ) above the mean = 54+6 = 60

1 standard deviation (-1σ) below the mean = 54 - 6 = 48

68% of the data of a normal distribution lies between -1σ and +1σ: between 48 - 60 requests

between 54 - 60 requests (between the mean and +1σ) is half of this percentage: 68/2 = 34%

Answer: 34%

Step-by-step explanation:

We can rearrange line M so it is in y = mx + b form.

2y - 10x + 3 = 0 -> 2y = 10x - 3 -> y = 5x -3/2. Since line L and line M have the same slope (which is the m value, 5), they are parallel.

I hope this helps! :)

Vsevolod [243]

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

<u>Question asked:</u>

What is the approximate length of the arc of the section containing the peas?

<u>Solution:</u>

The central angle formed by the peas = 360° - 105° - 203°

                                                                = 52°

Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches

As we know:

Length\ of\ arc=2\pi r\times\frac{\Theta }{360}

                        =2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.
