Substitute any value for zero on the equation to find the x and y intercept in order to graph:
10x-3(0)=-15
10x=-15
/10x /10x
x=-1.5
Repeat for y:
10(0)-3y=-15
-3y=-15
/-3 /-3
y=5
Answer:
The slope of the line is -12/3

remember, rise over run
My I have brainliest please? :)
Answer:
i think it is A because that seems like the one making the most sense
Step-by-step explanation:
3w. you find common factor for each. For 12 and 15 it is 3. For w and wz it is w. Combine them together you get the answer.
Answer:
the population means are known the population variances are assumed equal but unknown
Step-by-step explanation:
If σ1= σ2 (= σ) but unknown , then the biased pooled or combined estimate of the common variance σ² ( the term common variance means that each population has the same variance ) is given by
Sp²= (n1-1) s1² + (n2-1) s2²/ n1+ n2- 2
So first assumption is correct.
When the population variances are assumed unequal and unknown
If σ1 ≠ σ2 but unknown
we use the sample estimates s1 and s2 to compute the standard error of the difference between the means.
S(x1`- x2`) = √s1²/ n1 + s2²/n2
So this is does not apply here.
