Answer:
20, increased, Bianca
Step-by-step explanation:
First one:
He is shown to have travelled 20km in 1 hour, so that's 20km/h.
Second:
The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.
Third:
Bianca's line hits 50km before Alberto, so therefore she finished first.
Let me know if this makes sense, hope it helped! :D
So slope intercept form is y=mx+b m is the slope and b is the y intercept. The equation of this line would be y=1/4x+2 because the rise over run (slope) is 2/8 or 1/4 and the line intercepts the y axis at 2.
Answer:
-4
Step-by-step explanation:
Compare this to the form ...
y -y1 = m(x -x1)
which is the point-slope form of the equation for a line. Matching the parts of the equation, you see that ...
m represents the slope of the line. The slope is -4.
Using it's concept, there is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
From the histogram, the number of pitches is given by:
1 + 5 + 3 + 4 + 1 + 2 = 16.
Of those, 2 were between 70 and 75 mph, hence the probability is given by:
p = 2/16 = 1/8 = 0.125.
There is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
