Answer:
The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep soundtion:
The third one is the answer?
Answer:
<em>y = 3x</em>
Step-by-step explanation:
<u>Equation of a Line</u>
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
We are given the following values of the function: f(-1)=-3 and f(2)=6. The points are (-1,-3) and (2,6). The slope is:

Now find the equation of the line using the second point:
y - 6 = 3 ( x - 2 )
Operating:
y - 6 = 3x - 6
Simplifying:
y = 3x
Answer:
No, because the largest standard deviation is more than twice the smallest standard deviation.
Step-by-step explanation:
Okay, so the standard deviation for each of the sample is given as;
NHES II study = 2.486, NHANES II study = 2.408 and NHANES study = 5.851.
In order to determine whether the standard deviations satisfy the guidelines for the use of ANOVA, one of the conditions for anova for sample standard deviations must be considered that is;
'' the value of the sample standard deviations should not be times two of the smallest standard deviation."
In which if we have; highest sample standard deviations / smallest standard deviation < 2, Then, population variance is equal.
Answer:
32.
1st get the total age of the students
x/20 = 11
x=11x20
x =220 (total age of students)
add y ( teachers age) to the equation
(220 + y)/21=12
y= 32
