The value of x that makes lines a and b parallel is 76°.
This is because when two parallel lines are cut by a
transversal, the alternate angles formed by the transversal are equal. In the
figure below, the angle x is an alternative interior angle to the angle
measured 76°, so they are equal. That is, x = 76° (provided that line a is parallel to line b)
Answer:
Throw this sample out and start over again with a better sampling method
Step-by-step explanation:
Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.
Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.
Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.
Ur given a slope of 1/4. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will need a slope of -4. (see how I flipped 1/4 and made it 4/1 or just 4, and then changed the sign making it -4)
y - y1 = m(x - x1)
slope(m) = -4
(5,5)...x1 = 5 and y1 = 5
now we sub
y - 5 = -4(x - 5) <== ur perpendicular equation in point-slope form
Answer:
A two-step equation is an algebraic equation that takes you two steps to solve. You've solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
Step-by-step explanation:
1. x=-2, x=0
So, the equation in factored form would be x(x+2)=0.
2. x=0, x=4
So, the equation in factored form would be x(x-4)=0.
3. x=-2, x=0, x=4
So, the equation in factored form would be x(x+2)(x-4)=0.
