Answer:
The length of side st is 15.
Step-by-step explanation:
A tangent is a straigth line that touches a circle externally at a point on the circumference. Considering one of its properties that tangents from the same point to a fixed point outside a circle are equal.
Then,
/rn/ = /rp/
/tm/ = /tn/
/sm/ = /sp/
But, /rp/ = 7, /rt/ = 17 and /sm/ = 5.
Then,
/rt/ = /rn/ + /tn/
17 = 7 + /tn/ (∵ /rp/ = /rn/ = 7)
⇒ /tn/ = 10
Since /nt/ = 10, then /tm/ = 10 (/tm/ = /nt/)
So that,
/st/ = /sm/ + /tm/
= 5 +10
/st/ = 15
The length of side st is 15.
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
Mean = 10
Sample size = 9
Standard deviation = 6
We need to find the upper and lower control limits.
so, Lower limit would be

Upper limit would be

Hence, Third option is correct.
1 kilometer =5/3 week
Step-by-step explanation:
Given that the crew paves 3/5 kilometer of a road in 1 week then this can be written as;
3/5 k = 1 week
For 1 kilometer of a road,
3/5k = 1 week
1k=?
perform cross product as;/multiplication equation
1*1 / 3/5
1*5/3
5/3, 1 2/3 weeks
A division equation will be'
3/5 kilometers = 1 week
Divide both sides by 3/5
1 kilometer =5/3 week
