Function 1 Answer: 45
Function 1 Explanation: The rate of change (ROC) is basically the same thing as the slope of a graphed function. If you were to graph this table onto a coordinate plane, the slope of the line formed would be 45. (see Function 2 Explanation for more explanations, duh.)
Function 2 Answer: 40
Function 2 Explanation: Functions can be written in slope-intercept form, like this: y = mx + b. The <em>m</em> is the slope, or ROC (above), and the <em>b</em> is called the y-intercept, or where the line crosses the y-axis. The m in that equation is 40...
Hope that helps!! Sorry that took so long...
55*2=110, 360-110=250, 250/2=125. The answer is 125°.
Answer:
Step-by-step explanation:
-3x + 3y = 6.......(1)
y= 4x + 5............(2)
Putting (2) in (1)
-3x + 3(4x + 5) = 6
-3x + 12x + 15 = 6
9x = 6 -15
9x = -9
x = -9/9
x = -1
Putting x in (2)
y= 4x + 5
y = 4(-1) + 5
y = -4 + 5
y = 1
Answer:
, option D
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
From a random sample of 50 students, she found that 32 students read at least 1 book last month.
This means that 
90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Confidence interval:


So the correct answer is given by option D.
