Answer:The answer is 0.5b+7
Step-by-step explanation:
Answer:
A. = 3.053
B. = 1.85
C. =-1.85
D. since the z sore is less than -2, the highest weight is significantly low
Step-by-step explanation:
a) Difference between weights
= 5.31 - 2.527
= 3.053
b) Number of standard deviations = = 3.053÷1.655
= 1.85
c) the z score = \frac{\bar{X}-5.26}{s}
= (2.527 - 5.31 )÷1.655
= −3.053 ÷ 1.655
=-1.85
d) since the z sore is less than -2, the highest weight is significantly low

The generic equation for a linear function can be expressed in the slope intercept form f(x) = mx + b, where m is the slope and b is the y intercept. For this problem we can first find the equation of the line. Then we substitute x = 7 to get the f(x) value, which is n at the point x = 7.
To find the equation of the linear function we first find the slope. Slope is defined as the change in f(x) divided by the change in x. As we are given a linear function, the slope at every point is the same. We can pick any two points known to find the slope.
Let's pick (3, 7) and (9, 16). The slope m is m = (16-7)/(9-3) = 9/6 = 3/2.
Now that we have the slope, we can plug in the slope and one of the points to find b. Let's use the point (3, 7).
f(x) = mx + b
7 = (1/2)(3) + b
b = 11/2
Now we can write the equation
f(x) = (1/2)x + 11/2
Plugging in x = 7 we find that f(7) = 9. n = 9
