Answer:

65.6 degrees Fahrenheit

Step-by-step explanation:

The formula for mean is

sum of all values / number of values.

  Sum of values: 65 + 72 + 72 + 67 + 63 + 58 + 62 = 459

  Number of values: 7

  Mean: 459/7 = 65.571 = about <u>65.6</u>

stellarik [79]

Answer:

$44

Step-by-step explanation:

First, find how much he was making originally:

Multiply the number of hours he worked by the amount he got per hour:

20(8)

= 160

Then, find how much he gets now:

24(8.50)

= 204

To find his total weekly pay increase, find the difference between them:

204 - 160

= 44

So, his total weekly pay increase is $44

0.5x -2 = 1.5x + 0.15
frutty [35]

Answer: x=−2.15

Step-by-step explanation : Alright Let's solve your equation step-by-step.

0.5x−2=1.5x+0.15

Step 1: Subtract 1.5x from both sides.

0.5x−2−1.5x=1.5x+0.15−1.5x

−x−2=0.15

Step 2: Add 2 to both sides.

−x−2+2=0.15+2

−x=2.15

Step 3: Divide both sides by -1.

−x

−1

=

2.15

−1

x=−2.15<em>        hope this helped!- Alex</em><u> </u>

Betty's grade in science class is affected by the number of missing assignments. The table below shows the science grade percent
Angelina_Jolie [31]

Hi!

y=-5x+95

<em>Plug in </em>15 for x

y=-5(15)+95

<em>Multiply </em>-5 <em>and </em>15

y=-75+95

<em>Add </em>-75 <em>and </em>95

y =15

-------------------------------------------------------------------------------------------------------------

Betty's percentage is 15%.

The rate of change is the amount it changes for every missing assignment, therefore it would be -5.
