Answer:01 50 Hrs
Step-by-step explanation:
If the soldier started patrol at 2230 hrs and his petrol lasted for 3 hours and 20 minutes, that means he was on patrol for that time.
The time he finished was therefore:
= 2230 + 320
= 2550
At 24 you begin at 0:00am so:
= 2550 - 2400
= 150
Patrol ended at 0150 hrs
Answer:
use desmos :)) it helps
Step-by-step explanation:
Answer:
CI = (98.11 , 98.49)
The value of 98.6°F suggests that this is significantly higher
Step-by-step explanation:
Data provided in the question:
sample size, n = 103
Mean temperature, μ = 98.3
°
Standard deviation, σ = 0.73
Degrees of freedom, df = n - 1 = 102
Now,
For Confidence level of 99%, and df = 102, the t-value = 2.62 [from the standard t table]
Therefore,
CI = 
Thus,
Lower limit of CI = 
or
Lower limit of CI = 
or
Lower limit of CI = 98.11
and,
Upper limit of CI = 
or
Upper limit of CI = 
or
Upper limit of CI = 98.49
Hence,
CI = (98.11 , 98.49)
The value of 98.6°F suggests that this is significantly higher and the mean temperature could very possibly be 98.6°F
<h2>
The product of two numbers is <em>
a,</em>
of both numbers.</h2>
Step-by-step explanation:
Given,
The product of two numbers = a
To find, the both numbers = ?
Let the two numbers = x
∴ x × x = a
⇒
= a
⇒ 
Comparing the powers, we get
⇒ x = 
∴ First number =
and Second number =
Thus, the product of two numbers is <em>a,</em>
of both numbers.
Because BA ≅ BC, we know the triangle is isosceles. Because ∠FEC=90°, we know BE is a median and angle bisector of ∠ABC.
Hence ...
... AC = 2×AE = 20 in
... ∠EBC = (1/2)×∠ABC = 65°15'
