To find the standard error, divide the standard deviation by the square root of the sample size
standard deviation = 7.5
sample size = 25......sqrt 25 = 5
standard error = 7.5 / 5 = 1.5 <==
Answer:
y = 3x - 14
Step-by-step explanation:
If a line is parallel to another, it will have the same slope
So, the line's slope will be 3
Plug in the given point and the slope into y = mx + b, and solve for b
y = mx + b
-2 = 3(4) + b
-2 = 12 + b
-14 = b
Plug in the slope and b into y = mx + b
y = 3x - 14
So, the equation is y = 3x - 14
<span>(x + 6y) − (3x − 10y)
= x + 6y -3x + 10y
= -2x + 16y
Value of A: -2</span>
Answer:
9 cm
Step-by-step explanation:
It say ΔLMN and Δ PQR is equal
Therefore, LN is 9 cm Then PQ is 9 cm Too.
