8x-10y=-23
9x+10y=-16
(8x+9x)+(10y-10y)=(-23+(-16))
17x+0y=-39
x=-39/17
8(-39/17)-10y=-23
-312/17-10y=-23
-10y=-23+312/17
-10y=-79/17
y=79/170
Answer:
The correct option is;
B. I only
Step-by-step explanation:
The central limit theorem states that when adequately large random samples are taken from a population that has a mean, μ, and standard deviation, σ, the distributions of the sample means of individual samples taken will be more or less (approximately) normally distributed
The central limit theorem is correct for both normal and skewed populations such that estimates can be made about the population mean based on available sample mean information.
C. 3.0 is the nearest mean
Answer:
x=-5
Step-by-step explanation:
since the y's cancel out, set the first equation equal to the second and solve like you'd normally do.
Let Frances time = F
9 minutes less than frances time = F - 9
F - 9 is your expression
hope this helps
