Answer:
y=2/3x+4
Step-by-step explanation:
Looking at the line, we can see that from point (-3,2) to point (0,4) that the line moves 2 spaces upwards and 3 spaces to the right. Because of this, we know that the slope is 2/3 because we can simply put the rise (2) over the run (3).
Then, to find the y-intercept, we look to see where the line crosses the vertical axis, and in this case, that point is (0,4). So we now know the y-intercept is 4.
Finally, we put everything into slope-intercept form, and get y=2/3x+4
Answer:
The expected number of students is 79
Step-by-step explanation:
She find that she can model the data with the normal distribution. The formula for normal distribution is expressed as
z = (x - u)/s
Where
x = the time it takes for Ivy Tech students to travel to school.
u = mean time
s = standard deviation
From the information given,
u = 27.5 minutes
s = 5.2 minutes
The probability that a student's commute time would be less than 22.3 minutes is expressed as
P(x lesser than 22.3)
For x = 22.3
z = (22.3 - 27.5)/5.2 = - 1
Looking at the normal distribution table, the corresponding value for a z score of - 1 is 0.15866
The number if students out of 500 whose commute time would be less than 22.3 minutes would be
0.15866 × 500 = 79

Answer:
Step-by-step explanation:
lower left triangle: 5^2 + x^2 = 13^2
x^2 = 144 => x = 12
So, area of triangle is : (5 * (12-4))*0.5 => 20
Shaded area: (8 *12) -20 => 96 -20
