Answer:
false
Step-by-step explanation:
3×-8=-24
-171+9=-162
so -24 is not equal to-162
The quotient of 2 times some number and four.
Hope this helps and sorry if it is wrong but it’s what I got
Answer:
Maths is a very interesting subject, studying which - offers one with various positive & negative experience(s)
Step-by-step explanation:
Positive Experience : It enhances analytical, logical ability, which is useful in other subjects also. Eg - Accounts, Logical Reasoning
Negative Experience : It sometimes becomes bulky to solve, with loads of formulas & calculations. So, time management becomes a difficult task thereof
I would use the Law of Sines to solve this problem.
The angle next to the 58 degree angle is 122 degrees. The side opposite this angle is 3.72 km.
The angle we need to find is at the cave. The side opposite this angle is 2.60 km.
(Sin 122/3.72) = (Sin x/2.60)
Cross multiply to solve.
3.72 Sin x = 2.60 Sin 122
Divide both sides by 3.72
Sin x = (2.60 Sin 122)/3.72
Sin^-1 x = (2.60Sin122)/3.72
x = 36 degrees
According to the confidence interval only persons who watch at least 9.9 hours TV per day are eligible.
According to the statement
we have given that the mean of 7 hours per day watching TV, and a standard deviation of 1.8 hours.
And we have to find that the At least how many hours of daily TV watching are necessary for a person to be eligible for the interview.
So, For this purpose,
The confidence interval is is a range of estimates for an unknown parameter. A confidence interval is computed at a designated confidence level.
Let us Assume x is the amount of hours that 5% of the persons exceeds.
Then P(z<(x-7)/1.8) = 0.95
From a standard normal table, we know that:
(x-7)/1.8 = 1.6449
x-7 = 2.9607
x = 9.9607
So, According to the confidence interval only persons who watch at least 9.9 hours TV per day are eligible.
