Solution: We know that height of trees follows a normal distribution with mean height \mu=60 inches and standard deviation \sigma =12 inches

Now let's fill the missing values as per the normal distribution and the given information.

a0=34.1\% of 500 = 0.341 \times 500

           =170.5 \approx 171

Now, let's find the value of a1. Since the height follows normal distribution with mean 60 and standard deviation = 12. Therefore, we have:

a1=\mu+\sigma = 60+12=72

To find the value of a2, we need to use the empirical rule of normal distribution. According to empirical rule, the area between Mean and 1 standard deviation above mean is 34.1%. Therefore, the value of a2 is:

a2=34.1\%

a3 denotes the area between +1 and +2 (72 to 84 inches). According to empirical rule of normal distribution, the area between one standard deviation above mean and two standard deviation mean is 13.6%.

\therefore a3=13.6\%

And a4=13.6\% of 500=0.136 \times 500=68

Therefore, the complete table is attached here.

The edges of a cube are 5 cm each and the diaganol of a face is approximately 7 cm what is the approximate area of the cross sec
xxTIMURxx [149]

Answer:

The approximate area is 35 square centimeters

Step-by-step explanation:

we know that

The cross section passing through the diagonal of opposite faces of the cube is a rectangle

so

the approximate area is equal to

A=bh

where

b is the diagonal of a face

h is the length side of the cube

we have

b=7\ cm\\h=5\ cm

substitute

A=7(5)=35\ cm^2

Aleonysh [2.5K]

The angle for shooting laser gun should be 89.98°.

The vertical height where a tiny but horrible alien is standing is given as 443443443 meters. The horizontal distance of a men in black agent from building is given in the question as 181818 meters. So, let us assume the angle formed to be theta (θ).

Writing the formula for tan theta, that relates the given height and distance

Now, tan θ = vertical height ÷ horizontal distance

Keep the values in above mentioned equation of theta to find the angle.

tan θ = \frac{443443443}{181818}

Performing division to find the tan theta and subsequently calculate the angle

tan θ = 2438.94

θ = tan⁻¹ 2438.94

Calculating tan inverse to find the value of theta

θ = 89.98°

Therefore, the  angle for shooting laser gun by a men in black agent  should be 89.98°.
