Answer:
if x=ky, where k is constant.
value of x
45/3=k3/3
15=k, constant is 15
value of x when y =6
x=ky
x=15(6)
x=80

The z-score of the data can be calculated by the formula expressed as follows:
z = ( score - mean ) / standard deviation
z = (126 - 150 ) / 11 = <span>-2.18
</span>
A z-Score<span> is a statistical </span>measurement<span> of a </span>score's<span> relationship to the mean in a group of </span>scores<span>. A </span>Z-score<span> of 0 means the </span>score<span> is the same as the mean.</span><span>

Answer:
1. 6
2. 23
Step-by-step explanation:
1.
logx+1 ( x^2 + 2x + 1)^3
= 3logx+1 ( x^2 + 2x + 1)
= 3 logx+1 (x + 1)^2
= 6 logx+1 (x + 1) Now the logx+1 x+1 = 1 so
The answer is 6.
2.
log11 11^23
= 23 log11 11
As in question 1 log11 11 = 1
So the answer is 23.
