Answer:
a. y = 36x, b. $252
Step-by-step explanation:
Answer:
Is this a general equation?
Answer:
B, (6,0)
Take the average of the x values and the average of the y values:
(3+9)/2 = 6
(-2+2)/2 = 0
This means the answer (the average (midpoint) of the two points) is (6,0)
Answer:
-29
Step-by-step explanation:
substitute the y and x values whith there given values
so 1/3-2(3)-4(-1)2
first simplify (-1)2 or (-1)(-1) which is 1 so now the equation is 1/3-2(3)-4(1)
now you must solve all the values that have multiplying involved so you have 1/3-6-4
now subtract 6 and 4 to get 1/3-10
now find the LCD which is 3
multiply the LCD by both terms to get 1-30 which equals -29
Answer:
(a) 74.12633 mm ≤ μ ≤ 74.12767 mm
(b) μ ≥ 74.12649 mm
Step-by-step explanation:
Here we have;
Sample count, n = 15
Mean, = 74.127 mm
Standard deviation, σ = 0.001 mm
(a) The confidence interval, CI is given as follows;
At 99%, z = ±2.575829
Therefore, the confidence interval is;
74.12633 mm ≤ μ ≤ 74.12767 mm
(b) The lower confidence at 95% is given by;
z at 95% = 1.959964
or μ ≥ 74.12649 mm.
