Graph this function: y + 1 = 2(x + 3) Click to select points on the graph.
1 answer:
Answer:
use points (0,5) and (1,7)
see below for graph
Step-by-step explanation:
First, we'll turn the equation from point slope form (y-y1=m(x-x1)) into slope intercept form (y=mx+b)
y+1=2(x+3)
do the distributive property
y+1=2x+6
subtract 1 from both sides
y=2x+5
We'll need two points to graph the line.
You can subsitute x or y as any number you like and solve the equation.
For example:
if x=0:
y=2(0)+5
y=5
so the point would be (0,5)
and if x=1
y=2(1)+5
y=2+5
y=7
point: (1,7)
Use the points (0,5) and (1,7)

Answer:
Step-by-step explanation:
We know that:
Only employees are hired during the first 3 days of the week with equal probability.
2 employees are selected at random.
So:
A. The probability that an employee has been hired on a Monday is:
.
If we call P(A) the probability that 2 employees have been hired on a Monday, then:
B. We now look for the probability that two selected employees have been hired on the same day of the week.
The probability that both are hired on a Monday, for example, we know is . We also know that the probability of being hired on a Monday is equal to the probability of being hired on a Tuesday or on a Wednesday. But if both were hired on the same day, then it could be a Monday, a Tuesday or a Wednesday.
So
.
C. If the probability that two people have been hired on a specific day of the week is , then the probability that 7 people have been hired on the same day is:
D. The probability is . This number is quite close to zero. Therefore it is an unlikely bastate event.
