The hikers 3 miles from the trailhead to the waterfall.
d1 = 3 miles
Then, the hikers made a right turn and hiked another 3 miles until they stopped for lunch.
d2=3 miles
We can solve the distance when they returned to the trailhead using Pythagorean theorem:
D ² =d1² + d2²
D² = 3² + 3²
D = 4.24
The distance is 4.24 miles.
Answer:
80 square m
Step-by-step explanation:
We are given that
Mean=150 m
S.D=4 m
We have to find the variance of the total length of the wire in the coils.
Let X1, X2,X3,X4 and X5 are random variable of sample space of coil are choosing.
Var
for all i=1 to 5
Let X be the total length of coils
![X=X_1+X_2+X_3+X_4+X_5](https://tex.z-dn.net/?f=X%3DX_1%2BX_2%2BX_3%2BX_4%2BX_5)
![Var(X)=Var(X_1)+Var(X_2)+Var(X_3)+Var(X_4)+Var(X_5)](https://tex.z-dn.net/?f=Var%28X%29%3DVar%28X_1%29%2BVar%28X_2%29%2BVar%28X_3%29%2BVar%28X_4%29%2BVar%28X_5%29)
![Var(X)=16+16+16+16+16=80m^2](https://tex.z-dn.net/?f=Var%28X%29%3D16%2B16%2B16%2B16%2B16%3D80m%5E2)
Hence, the variance of the total length of the wire in the coils=80 square m
Answer:
$5909.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 5575 × 0.03 × 2 = 334.5
I = $ 334.50
The simple interest accumulated
on a principal of $ 5,575.00
at a rate of 3% per year
for 2 years is $ 334.50.
