Bill bought 38 1/2 feet of wire fencing to put around his blueberry plants. He cut the wire into several pieces, each one measur
Nadya [2.5K]

Answer: 7

Step-by-step explanation:

You are given that Bill bought 38 1/2 feet of wire. Convert the mixed fraction into improper fraction.

The length L1 = 77/2

You are given that he cut the wire into several pieces, each one measuring 5 1/2 feet. Convert it too to improper fraction.

The length L2 = 11/2

To know how many number of pieces of wire he have after making the cuts, divide length L1 by length L2. That is,

L1/L2 = 77/2 ÷ 11/2

Change the division to multiplication by reciprocating 11/2 to 2/11

77/2 × 2/11 = 77/11 = 7

Therefore, he had 7 pieces of wires after making the cuts.

Laboratory experiment shows that the life of the average butterfly is normally distributed with a mean of 18.8 days and a standa
inessss [21]

Answer:

a) 0.4164

Step-by-step explanation:

Mean lifespan (μ) = 18.8 days

Standard deviation (σ) = 2 days

For any given lifespan 'X', the z-score is:

z=\frac{X- \mu}{\sigma} \\z=\frac{X- 18.8}{2}

For X=12.04 days:

z=\frac{12.04 - 18.8}{2} \\z=-3.38

A z-score of -3.38 falls in the 0.036-th percentile of a normal distribution.

For X=18.38 days:

z=\frac{18.38 - 18.8}{2} \\z=-0.21

A z-score of -3.38 falls in the 41.68th percentile of a normal distribution.

The probability that a butterfly lives between 12.04 and 18.38 days is

P=41.68-0.036\\P=41.64\%\ or\ 0.4164
