23
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
First find the pattern. The pattern is you multiply the number before by -3.
Just start with x as the first number.
x, -3x, 9x, -27x, 81x, -243x, 729x, -2187x, 6561x, -19683x
Add them all up: -14762
Now multiply by -3:
44286

Answer:
No ;
Step-by-step explanation:
Given ;
s2 = 10 ; n2 = 10 ; s1 = 12 ; n1 = 12
Hypothesis :
H0 : σ1² = σ2²
H1 : σ1² ≠ σ2²
The test statistic :
Ftest = s1² / s2² = 12² / 10² = 144 / 100 = 1.44
The Pvalue using the Pvalue from Ftest calculator :
Numerator df = 12 - 1 = 11
Denominator df = 10 - 1 = 9
Pvalue = 0.2969
At α = 0.1
If Pvalue > α ; Fail to reject H0
0.2969 > 0.1 ; Hence, we fail to reject the Null
Hence, we cannot conclude that variation exists
Answer:
x=33°
Step-by-step explanation:
Hi there!
We're given a triangle, with 2 known measures of angles in the triangle
54° and 93°
the other (unknown) value is x
the angles in a triangle add up to 180°
therefore, to find the value of x, we can add up the values of the 3 angles and set that to equal 180
54°+93°+x°=180°
add 54 and 93
147°+x°=180°
subtract 147 from both sides
x=33°
so the value of x is 33 degrees
Hope this helps!
