Answer:
Step-by-step explanation:
Given that :
μ1 = 39420 ; σ1 = 1659 ; s1 = 12
μ2 = 30215 ; σ2 = 4116 ; s2 = 26
df1 = 12 - 1 = 11
df2 = 26 - 1 = 25
98 % confidence interval of the difference in sample means :
Pooled Variance :
S²p = ((df1 * s1²) + (df2 * s2²)) / (df1 + df2)
((11×1659^2)+(25×4116^2))÷(11+25) = 12605874.75
Standard Error :
√(S²p/n1) + (S²p/n2)
√(12605874.75/12) + (12605874.75/26)
= 1239.0847
Answer:
D.
Step-by-step explanation:
In direct variations, we would have:
Where <em>k</em> is some constant.
Since this is indirect variation, instead of that, we would have:
To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>
<em />
<em />
Now plug this back into the variation:
The answer is D.
The third statement does not describe a correlation all relationship because some children’s vocabulary does not increase as they get older, but their weight does.
Answer:
153.86 yards²
Step-by-step explanation:
A(Circle) = πr² where r = radius.
r = d/2 where r = radius and d = diameter.
r = 14/2 = 7 yards.
(3.14)(7)² = (3.14)(49) = 153.86 yards²
In term of Angles, they're the same.
So like
2x + 62 = 5x + 38
(-2x)
62 = 3x + 38
(-38)
24 = 3x
(/3)
x = 8
