so b) circumcenter
Answer:
If the lifetime of batteries in the packet is 40.83 hours or more then, it exceeds for 5% of all packages.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 15
Standard Deviation, σ = 1
Sample size = 4
Total lifetime of 4 batteries = 40 hours
We are given that the distribution of lifetime is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
We have to find the value of x such that the probability is 0.05
P(X > x) = 0.05
Calculation the value from standard normal z table, we have,
Hence, if the lifetime of batteries in the packet is 40.83 hours or more then, it exceeds for 5% of all packages.
we are given
where
d is the horizontal distance the ball traveled in yards
f(d) is the height, in yards of the ball at d horizontal yards
Initial height:
For finding initial height , we can plug d=0
So, initial height is 0.8 yard
Initial Velocity:
We can find derivative
now, we can plug d=0
so, initial velocity is 5.4 yard vertically / yard horizontally
Hence , option-B.......Answer
Answer:
Step-by-step explanation:
Open the brackets
3 x 2x = 6x
3x -3 = -9
4 x 2x= 8x
4 x 4= 16
6x - 9 = 8x + 16
Move same to same side
-16 -9 = 8x - 6x
-25 = 2x
x -25/2
x = -12.5
