Answer:
The rate of change will be $25
Step-by-step explanation:
Since she started from $45 we have to count again so on the chart it goes 5, 10, 15, 20, and 25!

Answer:
-1/2
Step-by-step explanation:
The slope of the given line is the coefficient of x, which is 2.
The slope of the perpendicular line is the negative reciprocal of that:
-1/2
mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.
Answer:
-3, 7
Step-by-step explanation:
because you take how much from the first coordinate to the second and add it too the second
Compound inequality combines multiple single inequalities.
The solution and interpretation of the inequality is:
<em />
<em> and </em>
<em>. Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates.</em>
<em />
We have:
and 
Solve for x in both inequalities
Divide both sides by 2
Rewrite as:
Also, we have:
Divide by 2
So, the solutions to the inequalities are:
and
This means that Ryan needs to consume more than 50 but less than 150 grams of carbohydrates.
Hence, (a) is correct
