Answer:
1/3
Step-by-step explanation:
1/2 of 2/3 = 1/2·2/3 = (1·2)/(2·3) = 1/3
Answer:
83
Step-by-step explanation:
x = 1st number
x+2 is the next consecutive odd number
x+ x+2 = 164
Combine like terms
2x+2 = 164
Subtract 2 from each side
2x= 162
Divide by 2
2x/2 =162/2
x = 81
x+2 = 83
The largest number is 83
Answer:
option (d) 16.6 and 21.4
Step-by-step explanation:
Data provided in the question:
The mean life for a particular use before they failed = 19.0 hours
The distribution of the lives approximated a normal distribution
The standard deviation of the distribution = 1.2 hours
To find:
The values between which 95.44 percent of the batteries failed
Now,
In Normal distribution, the approximately 95% ( ≈ 95.44% of all values ) falls within 2 standard deviations of the mean
Therefore,
Upper limit = Mean + 2 × standard deviation
⇒ Upper limit = 19.0 + 2 × 1.2 = 21.4
Lower limit = Mean - 2 × standard deviation
⇒ Lower limit = 19 - 2 × 1.2 = 16.6
Hence,
the answer is option (d) 16.6 and 21.4
Answer:
the answer is 20,21,29 because
20 times 20 is 400
21 times 21 is 441
and 29 times 29 is 841
the formula to ge tthe answer is a^2 + b^2 = c^2
20^2 + 21^2= 29^2
then plug the rest in
400+441= 841
