So, I assume that you mean 26 students times the teachers. 
You can create two equations out of this information.
s = students while t = teachers
26t = s
900 - 9 = 891 seats being occupied
s + t = 891
You can use these two equations for substitution.
s = 891 - t
26t = 891 - t
27t = 891
t = 31
So, 31 teachers. Now plug that back into an original equation.
s + (31) = 891
s = 860
860 students.

(x^4)^3=(x^3)^4 true or false
telo118 [61]

Step-by-step explanation:

(x^4)^3=(x^3)^4 , true

=> x^(4×3) = x^(3×4) = x^12

13^4 x 13^7= (13^4)^7, false

13^(4+7) = 13^11

(13^4)^7 = 13^(4×7) = 13^28

y^5 x y^0/y^3=(y^2)^1 , true

y^5 x y^0/y^3 = y^(5+0-3) = y^2

(y^2)^1 = y^(2×1) = y^2

q^0 x q^5/q^2=(q^3)^2/q^3, true

q^0 x q^5/q^2= q^(0+5-2)= q^3

(q^3)^2/q^3 = q^(3×2-3) = q^3

A sample size of 500 is sufficiently large enough to conclude that the sampling distribution of the sample proportions is a norm
Paha777 [63]

In a statistical test, the null hypothesis to be made is that the sample proportions do not have any significant differences, which means an equal distribution. This is only rejected when the estimate is equal or less than 0.95. But since in this case it is >0.95, so therefore the null hypothesis is not rejected. Therefore:

<span>False</span>
