Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
True mean(μ) = 77.9
True standard = 20
Sample size (n) = 50
Sample mean (m) = 82.1
Sample standard deviation (s) = 18.6
The standard error (SE) :
SE = sample standard deviation / √sample size
SE = 18.6 / √50
SE = 2.6304372
SE = 2.63
Answer: -8
Step-by-step explanation: because the formula is mx+b=y and the -8 is the b
Quadrant: one of the four region into which the x and y axis separate the coordinate plane
Ordered pairs: a pair of numbers that are used to correspond to a pint on a graph where the first number is the x coordinate and the second is the y coordinate
Y-intercept: the point where a graph crosses the y-axis
Parallel lines: Lines that have the same slope and never intersect
Slope intercept form: A linear equation in the form y=mx+b where m is the slope and b is the y-intercept
Linear Equation: An equation with two variables that makes up a straight line on a coordinate plane
Answer:
x=20
Step-by-step explanation:
x=20 because (4x+3)=77 so you take out of parnetheses
