Answer:
The correct answer is C. 224
Step-by-step explanation:
Sn = n/2 (2*A1 +d(x-1))
S7=7/2(2*17+5(7-1))
S7=7/2(34+30)
S7=7/2(64)
S7=7*64/2
S7=7*32/1
S7=224

Degrees of freedom is defined as the number of independent values or quantities which can be assigned to a statistical distribution.
#In a two sample study, the t-statistic degrees of freedom is calculated as
#Where
denotes the sample size of the
sample.
![DoF=(15+15)-2=28](https://tex.z-dn.net/?f=DoF%3D%2815%2B15%29-2%3D28)
The t-statistic degrees of freedom is thus 28
<span>We can find as follows
x D=x^2/9
speed braking distance
mph in feet
20 44.44
60 400.00
b) x^2/9=16
x^2=144
x=12 mph</span>
