7-4= 3. Then 3 times 0= 0. Plus one would equal 1 :)
Answer:
Yes
Step-by-step explanation:
To determine if this is a right triangle, use the pythagorean theorem and see if a^2 + b^2 is equal to c^2.
a^2 + b^2 = c^2
12^2 + 16^2 = 20^2
Evaluate the exponents.
144 + 256 = 400
Add them together.
400 = 400
Since a^2 and b^2 add up to equal c^2, this is a right triangle.
So you would do 13+2 then add 3 then plus that by five
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.
