Answer: C. 375
Step-by-step explanation:
All your doing is multiplying
Answer:
5
Step-by-step expTo find IQ Range, you take the Third Quartile and subtract it by the First Quartile to get your answer.
80% of x = 0.80x or 4x/5
Any fraction equivalent to 80/100 can be used to multiply x. You could also divide x by any equivalent to 5/4 or 1.25.
Answer: C. Y = 5x + 5
Step-by-step explanation:
We need to write, or decide on, the equation for the blue line as this line represents the trend line for this scatter plot. We will write this in slope-intercept form. <em>See attached for a visual</em>.
First, we will find our slope. We will use
for this since we have a graph with clear points. See attached, we count up [5] and then count to the right [1] for a slope of 5.
-> Slope = 5
Now, we will find our y-intercept. This is where the line intersects the y-axis. The line hits the y-axis at point (0, 5) giving us a y-intercept of 5.
-> Y-intercept = 5
Lastly, we will write our equation and decide on an answer.
y = <em>m</em>x + <em>b</em>
y = (5)x + (5)
Y = 5x + 5
C. Y = 5x + 5
