Answer:
<em>The correct option is : C. 3.4</em>
Step-by-step explanation:
The probability that a person shopping at a certain store will spend less than $20 is 0.2
That means, here 
Given that, the sample size
So, the Mean 
Thus, the mean number who spend less than $20 will be 3.4
Answer:
he has a 4/5 chance to hit bulls-eyes.
Step-by-step explanation:
Using the point slope form y - y1 = m(x-x1)
m is the slope, because the lines are parallel the slope is identical, so m = -2.
Replace x1 and y1 with the given point and then solve for y:
y - 1 = -2(x-4)
Simplify:
y - 1 = -2x + 8
Add 1 to both sides:
y = -2x +9
Answer:
They are perpendicular.
Step-by-step explanation:
When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.
