Answer:

$39.2

Step-by-step explanation:

The sale price will be 20% of $49 subtracted from $49

That’s

20% /100% x $49

0.2 x $49

$9.8

Sale price = $49 - $9.8

= $39.2

The sale price is $39.2

Find the range of the graphed function.
rusak2 [61]

Range is set of all y-values. To find a range of graphed function, we need to know that range starts from the minimum value of graph to maximum value. That's because the minimum value is the least value that you can get by substituting the domain and the maximum value is the largest value that you can get by substituting the domain as well.

Now we don't talk about domain here, we talk about range. See the attachment! You are supposed to focus on y-axis, plane or vertical line. See how the minimum value of function is the negative value while the maximum value is positive.

That means any ranges that don't contain the negative values are cleared out. (Hence A and C choices are wrong.)

Next, range being set of all real numbers mean that graphed functions don't have maximum value or minimum value (We can say that both max and min are infinite.)

Take a look at line graph as an example of range being set of all real numbers, or cubic function.

Answer/Conclusion

  • The range exists from negative value which is -9 to the maximum value which is 5.
  • That means the range is -9<=y<=5

A cell phone company says that a fully charged battery lasts 14 hours. In reality, each battery behaves a little differently. Fo
gregori [183]

Answer:

The percentage is 50%

Step-by-step explanation:

From the question we are told that  

     The  mean is  \mu  =  14 \  hours

     The  standard deviation is \sigma =  1 \  hour

Generally on the normal distribution curve the mean divides the curve into  two. with the half to the left of the mean (50% to the left )representing the percentage of the batteries that will last less than 14 hours and  the area under the curve to the right (50% to the right)representing the percentage of batteries that will last longer than mean (14 hours )

Hence the percentage of the cell phone batteries that will be expected to last longer than 14 hours is 50%

To solve a one-step equation, you must _____<br> the variable.
krek1111 [17]

Answer:

Isolate.

Step-by-step explanation:

To solve a one-step equation, you must isolate the variable.

For example,

3x = 9.

You must isolate x, which just means you have to get x by itself.

Divide by 3 on both sides to get x by itself.

x = 3.

The answer to this question is isolate.
