Answer:
The percentage of boys students in Jamie's class is 20 %
Step-by-step explanation:
Given as :
The total number of boys in the Jamie's class = 
of the total student
Let the total number of student's in the class = x
So, The number of boys = × x
I.e The number of boys = 
So , in percentage the number of boys students in class = 
× 100
OR, % boys students = 
× 100
or, % boys students = 
∴ % boys students = 20
Hence The percentage of boys students in Jamie's class is 20 % . Answer
Answer:
10.6%
Step-by-step explanation:
Normal curves are symmetrical. That means that on a standard normal distribution, the area less than -1.25 is the same as the area greater than +1.25. The total area under the curve is 1, so:
P = 1 - 0.894
P = 0.106
Approximately 10.6% of the area under the curve lies below -1.25.

Explanation:
<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>
If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.
If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.
<span>The correct answer is (a) total deviation equals unexplained deviation plus explained deviation.
These deviations are commonly encountered or studied in statistics, and sometimes in regression analysis.</span>
