Answer:
1400m
Step-by-step explanation:
X*30%=420, X=420/30%=420/0.3=1400
Here are the choices
The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with positive correlation can have either weak correlation or strong correlation.
The slope of a line is independent of whether the correlation of a scatterplot has positive or negative correlation. A scatterplot with a negative slope can have either positive correlation or negative correlation.
The nonlinear association of a scatterplot depends on whether it has a weak or strong correlation. A scatterplot with nonlinear association will have a strong correlation.
The nonlinear association of a scatterplot depends on whether it has a positive or negative correlation. A scatterplot with nonlinear correlation will have a negative correlation.
It's a, because if it is positive, it can either be one skinny line, or one thick fat confusing line. Positive isn't perfect.
Answer:
Here, Diameter of the whole tube = 10 m
Diameter of the inner tube= 10mm - 2 mm= 8mm
Now,
Area of the shaded region =1/4 ×πd^2
=1/4×3.14×8^2
=50.24 mm^2
The answer is:
32x^5+ 240x^4+ 720x^3+ 1080x^2+810x+243
Hehe i hope it can help you
