Answer:
A: -6.5
Step-by-step explanation:
Take two points that we already know are on the line and find the slope
I used:
(4, -10) and (7, -30)
X1 (first x coordinate): 4
Y1 (first y coordinate): -10
X2 (second x coordinate): 7
Y2 (second y coordinate): 30
These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.
Use (Y2-Y1)/(X2-X1)
(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.
The closest answer to that is A.
Answer:
x = 10 and x = -2
Step-by-step explanation:
The equation has 2 solutions because we have a square. When things are squares, we get a positive and negative solution.
(x-4)^2 - 28 = 8
Add 28 to each side
(x-4)^2 - 28+28 = 8+28
(x-4)^2 = 36
Take the square root of each side
sqrt((x-4)^2) = ±sqrt(36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4 ±6
x = 4 ±6
x = 4+6 and x = 4-6
x = 10 and x = -2
Answer:
0.375
Step-by-step explanation:
Given that F is the event that a student is enrolled in a finance course, and let S be the event that a student is enrolled in a statistics course.
It is known that 40% of all students are enrolled in a finance course and 35% of all students are enrolled in statistics. Included in these numbers are 15% who are enrolled in both statistics and finance.
P(F) = 0.40: P(S) = 0.35: P(FS) = 0.15
A student is randomly selected, and it is found that the student is enrolled in finance.
Probability that this student is also enrolled in statistics/ student is enrolled in finance.
= 
(Using conditional probability formula)
Answer:
y = 8x
Step-by-step explanation:
A proportional relationship has the form
y = kx ← k is the constant of proportion
The only equation in this form is
y = 8x
Answer:
its kinda tricky because the actual size is 350ft tall so its pretty difficult??
