Answer:
test stat=1.7986
p value =0.0391
Step-by-step explanation:
given
n=50
d = 7.3
s d = 28.7
formula to calculate test statistic
t=
⇒ t=
⇒t=1.7986
for 49 df and t=1.7986 ,p value can be obtained from software
p value=0.0391
ST^2 = 7 ( 7 + 23) ( I think its called the tangent/secant length theorem)
ST^2 = 210
ST = sqrt 210 = 14.49 to nearest hundredth.
Answer:
The formula for slope intercept is y=mx+b and m is the slope and B is our y intercept. so if we just input our values:
y=2x-4
you also you could write the slope as 2/1 since the slope is rise over run (rise/run)
3 1/2 miles/ (1 1/4 hour)
= (7/2 miles)/ (5/4 hour)
= 7/2* (4/5) miles/hour
= 2.8 miles/ hour
The final answer is 2.8 miles/ hour~
