Answer:
(-9, -26)
Step-by-step explanation:
y = (x - 1)2 - 6 and y = 4x + 10
Since they are both y =, you can set the two equations equal to each other:
(x - 1)2 - 6 = 4x + 10
2x - 2 - 6 = 4x + 10
-2 - 6 = 2x + 10
-8 = 2x + 10
2x = -18
x = -9
Check:
y = (x - 1)2 - 6
y = (-9 - 1)2 - 6
y = -18 - 2 - 6
y = -26
y = 4x + 10
y = 4 (-9) + 10
y = -36 + 10
y = -26
The answer to these equations is (-9, - 26). If you graph this, this is the point where the two graphs intersect.
Answer:
57.5
Step-by-step explanation:
The expected frequency of West Campus and Failed :
Let :
Failed = F
East Campus = C
West Campus = W
Passed = P
Frequency of FnW :
[(FnE) + (FnW) * (PnW) + (FnW)] / total samples
[(52 + 63) * (63 + 37)] / 200
[(115 * 100)] / 200
11500 / 200
= 57.5
n(Failed n East campus)
Answer:
The length of the office is 36.4 ft
Step-by-step explanation:
The length of the classroom = 20 ft long
The length of the office = 20 ft + 82% of the classroom length
Now, 82 % of classroom length = 82 % of 20 ft
⇒
or, 82% of 20 ft = 16.4 ft
⇒The length of the office = 20 ft + 16.4 ft = 36.4 ft
Hence, the length of the office = 36.4 ft
