shemillie earns $8 per hour at a yogurt store. she receives a 5% raise. What are her new hourly earingings?
Soloha48 [4]

A 5% raise means that you have to find out what 5% of 8 is and then add that to 8:

5/100 * 8 = 40/100 = $0.40

8 + 0.40 = $8.40.

If changes are made to a signature while using version 5.x signature files, are they visible in the router running the configura
tatyana61 [14]
I think that the changes will not be visible in the router running the configuration. This is because they are not part of the router configuration. The version 5.x signature is more advantageous it has an additional signature risk rating feature and it supports encrypted signature parameters. <span />

If a number x is chosen at random from the numbers -2,-1, 0, 1,2.what is the probability that x2&lt;2.
Katyanochek1 [597]

Answer:

Do you mean 2x<2 or

X <2 or do you mean x²<2

Step-by-step explanation:

If your question is X²<2

Then

Total outcomes=5

Possible outcomes=3(-1,0,1)

Probability of x²<2=3/5

If your question means probability of2x<2

Then

Total outcomes=5

Possible outcomes=3 (-2,-1,0)

Probability of 2x<2=3/5

If your question means x< 2

Then

Total outcomes=5

Possible outcomes=4 (-2,-1,0,1)

Probability of x <2 =4/5

Find the distance between (-3,-1) and (4, 2). (Round up to the nearest hundredths.)
yanalaym [24]

Answer:

The answer is

<h2>7.61 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,-1) and (4, 2).

The distance is

d =  \sqrt{ ({ -  3 - 4})^{2}  +  ({ - 1 - 2})^{2} }  \\  =  \sqrt{ ({  - 7})^{2}  +  ({ -   3 })^{2} }  \\  =  \sqrt{49 + 9}  \\  =  \sqrt{58}  \\  = 7.615773

We have the final answer as

<h3>7.61 units to the nearest hundredth</h3>

Hope this helps you
