The point’s new coordinates would be (4,-4). When you’re reflecting across the x-axis, just change the y coordinate to it’s opposite, like a negative to a positive and vice versa.

Radda [10]

Answer:

68%

Step-by-step explanation:

The Standard Deviation Rule = Empirical rule formula states that:

68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question,

Step 1

We have to find the number of Standard deviation from the mean. This is represented as x in the formula

μ = Mean = 61

σ = Standard Deviation = 8

For x = 53

μ - xσ

53 = 61 - 8x

8x = 61 - 53

8x = 8

x = 8/8

x = 1

For x = 69

μ + xσ

69 = 61 + 8x

8x = 69 - 61

8x = 8

x = 8/8

x = 1

This falls within 1 standard deviation of the mean where: 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

Therefore, according to the Standard Deviation Rule, the approximate percentage of daily phone calls numbering between 53 and 69 is 68%

maxonik [38]

Step-by-step explanation:

figure of speech in which a character or speaker addresses someone who is absent. This could be a person they know or don’t know someone who is alive or dead, or someone who never existed at all. It might also be a non-human animal, an abstracted, but personified force, or even an object. Often, this technique is used when a speaker addresses a god or group of gods.

Apostrophe Examples

Twinkle, twinkle, little star, how I wonder what you are. ( ...

O holy night! ...

Then come, sweet death, and rid me of this grief. ( ...

O, pardon me, thou bleeding piece of earth. ( ...

Roll on, thou deep and dark blue Ocean – roll! ( ...

Welcome, O life!
