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%

Please help me on this one?
blondinia [14]

3x + 4y = 16             Subtract 4y from both sides. Put brackets around the 2 terms on the right.

3x + 4y - 4y = (16 - 4y)

3x = (16 - 4y)            Divide by 3

\text{ x =}\dfrac{(16 - 4y)}{3} = \dfrac{16}{3} - \dfrac{4y}{3}

Answer That's B.
