Answer:78.5
Step-by-step explanation:
Because the diameter is always going to be twice the radius and area equal pi which is 3.14
1 year 500 x .06 = 30.00
2 year 530 x .06 = 31.80
Answer 531.80
Answer:
0.9544
Step-by-step explanation:
We are given that mean=18 and standard deviation=1 and we have to find P(16<X<20).
P(16<X<20)=P(z1<Z<z2)
z1=(x1-mean)/standard deviation
z1=(16-18)/1=-2
z2=(x2-mean)/standard deviation
z2=(20-18)/1=2
P(16<X<20)=P(z1<Z<z2)=P(-2<Z<2)
P(16<X<20)=P(-2<Z<0)+P(0<Z<2)
P(16<X<20)=0.4772+0.4772=0.9544
The probability that the height of a tree is between 16 and 20 feet is 95.44%
Answer:
x = 69
Step-by-step explanation:
x+x+(x-27) = 180
3x = 207
x = 69
