Answer: 2.28%
Step-by-step explanation:
Given: An airport find that at the present time, the mean noise level is 103 decibels and the standard deviation is 5.4 decibels.
The distribution of noise levels(x) for all jets during takeoff over the neighborhood has a normal distribution.
The probability that jets have a noise level less than 92.2 decibels when taking off over this neighborhood will be :-
Hence, the percent of these jets have a noise level less than 92.2 decibels when taking off over this neighborhood = 2.28%
Answer:
x=80, y=15
Step-by-step explanation:
The angle on the opposite side of 100 will be equal to x
We know it is 180-100 so x=80
We know 6y=90
therfore y = 90/6 which equals 15
so y=15 and x=80
Answer:
160 not interested and 144*
Step-by-step explanation:
* is the degree sign like the little o
Since he bought more than one of each, he needs to find the total cost of the biscuits and sausage first.
The correct answer should be:
<span>B. Step 1: Calculate the price of 3 biscuits. Step 2: Calculate the price of 3 sausages. Step 3: Add the total amounts from Steps 1 and 2 to the amount of the tip. Step 4: Subtract that total amount from $25.</span>
The triangle inequality tells you the third side will be between the difference and sum of the other two sides.
5 < third side < 21
