Answer:
The distance of the plane from the base of the tower is 25.5 foot.
Step-by-step explanation:
As given
Max is in a control tower at a small airport.
He is located 50 feet above the ground when he spots a small plane on the runway at an angle of depression of 27°.
Now by using the trigonometric identity.
As shown in the figure given below
Perpendicular = CB
Base = AC = 50 feet
Put in the identity.
Put in the above
CB = 0.51 × 50
CB = 25.5 foot
Therefore the distance of the plane from the base of the tower is 25.5 foot.

The cost of one can of tuna is $1.50/3, or $0.50 per can.
Answer:
0.683
Step-by-step explanation:
We have to find P(-1<z<1).
For this purpose, we use normal distribution area table
P(-1<z<1)=P(-1<z<0)+(0<z<1)
Using normal area table and looking the value corresponds to 1.0, we get
P(-1<z<1)=0.3413+0.3413
P(-1<z<1)=0.6826
Rounding the answer to three decimal places
P(-1<z<1)=0.683
So, 68.3% of the z-scores will be between -1 an 1.
Answer:
Width is 5 and length is 7
Step-by-step explanation:
You can solve the equation using the distributive property and inverse operations.
2x +2(x+2)=24
2x + 2x + 4 = 24
4x + 4 = 24
4x = 20
X = 5
This means the width is 5 and the length is 7.
