Answer:
8 units
Step-by-step explanation:
AB = √(4×(4+12))
= √(4×16)
= 2×4
= 8 units
Answer:
<h2>B. Standard</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The standard form of an equation of a line:
The general fom of an equation of a line:
We have the equation 3x - 2y = 4 in standard form.
Answer:
x=12.22
Step-by-step explanation:
Sin(70)=13/x
xsin(70)=13
x=sin(70)13
x=12.22
Answer:
z-test.
Step-by-step explanation:
We want to perform an hypothesis test for a population mean.
In the case that the <u>standard deviation of the population is known</u> and the population distribution is normal, even if the sample is small, <u>we will use a z-test</u>.
The usual case is to not know the standard deviation of the population, in which case a t-test is adequate instead of a z-test, taking into account the degrees of freedom of the sample.
