A= d+26
a-2= 2(d-2)
Substitute for a
d+26-2= 2d-4
Combine like terms
d+24=2d-4
Subtract d from both sides
24=d-4
Add 4 to both sides
d=28
Final answer: 28
Answer:
HL
Step-by-step explanation:
It doesn't specifically mention that the Hypotenuse of the two triangles are congruent.
Answer:
WE fail to reject the Null and conclude that ; Standard deviation of test hasn't decreased.
Step-by-step explanation:
The hypothesis :
H0 : σ = 13
H1 : σ < 13
Using the Chisquare Square statistic :
χ² = (n-1)*s²/σ²
Sample size, n = 25
s² = 6.0547²
σ² = 13²
χ² = (25 - 1)*6.0547² / 13²
χ² = 879.82541016 / 169
χ² = 5.206
The degree of freedom, df = 25 - 1 = 24
The Pvalue(5.206, 24) = 0.99981
Reject H0, if Pvalue < α ;
Since Pvalue > α ; WE fail to reject the Null and conclude that ; Standard deviation of test hasn't decreased.
Answer:
The slope <em>m</em> is 1.9 and the y-intercept <em>b</em> is 2.5.
Step-by-step explanation:
This is in slope-intercept form, y=<em>m</em>x+<em>b</em>, where <em>m</em> is slope and <em>b</em> is the y-intercept.
y = 1.9x + 2.5 means that <em>m </em>is 1.9 and <em>b</em> is 2.5.
