Solution :
Assuming 
We have to test

Against 
Level of significance, 


= 420.6107
Under
, the t-statistics is as follows:


= 0.90
DF = (25 + 20 - 2)
= 43
P-value of the test = 0.375
Since the p value is more than 0.05, we fail to reject our null hypothesis.
There is no difference between then mean tensile strength of the ropes that is produced in the Bozeman and Challis.
QS =25
Step-by-step explanation:
QR + RS = QS
18 + (x-11) =2x-11
7 +x =2x -11
18=x
Plug in x
2(18) -11
36-11
QS=25
18 + (18-11) = 2(18)- 11
18+ 7 = 36 -11
25= 25
True
Answer:
QS + QR > RS
QR + RS > QS
RS + QS > QR
Step-by-step explanation:

Answer:
y=-1/4x+8
Step-by-step explanation:
To find the equation of a line that is perpendicular to a line, you would take the opposite reciprocal of the slope.
Before that, we need to change the equation into slope-intercept form.
-4x+y=10
y=4x+10
The opposite reciprocal of the slope is -1/4.
Now, let's use the point-slope formula to find our equation of the line that passes through (-4,9).
y-y1=m(x-x1)
y-9=-1/4(x-(-4))
y-9=-1/4x-1
y=-1/4x+8
Answer:
its 13.83
Step-by-step explanation:
Use the distance formula and plug them in
