Answer:
the answer is D
Step-by-step explanation:
just add the x into the equation. example→ -5(16)+80 =0. based on the graph the dot is on the true line so it make sense. i use x=16 based on the graph to get y. if x and y is match with the equation then thats was the answer. sorry if my answer is wrong.
(t^3-t)/a=b because a t the simple of questions
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.
Answer:
y = -3x - 6
Step-by-step explanation:
first, find the slope
(-4, 6)
(1, -9)
remember the equation for the slope
insert given points
((-9) - (6)) / ((1) - (-4))
simplify
( -9 - 6) / (1 + 4)
= -15/ 5
= -3
now insert it into the equation of the line
remember, the equation of the line is
y = mx + b
where "m" is the slope
and "b" is the y-intercept
to find "b", you just have to plug in a point that is found on the line
we know that (-4, 6) and (1. -9) is found on the line, so let's just use (-4, 6) for this problem
y = mx + b
substitute in the slope of this line
y = -3x + b
now substitute in the given points
6 = -3 * -4 + b
and solve it like any algebra problem, by inverse operations and simplifying
6 = 12 + b
-12 -12
-6 = b
so the equation of the line is
y = -3x -6
Answer:
65
62
Step-by-step explanation:
In inscribed quadrilaterals, opposite angles are supplementary.
First problem:
x + 148 = 180
x = 32
2x + 1 = 65
Second problem:
x + 20 + 3x = 180
x = 40
180 − (2x + 38) = 62
