Area of pond:

A=\pi r^{2}

r=1,5m

A=3,142*1,5*1,5=7,0695

Area of pond with path

B=\pi r^{2}

r=50 cm+1,5m=0,5m+1,5m=2m

B=3,142*2*2=12,568

Area of path:

12,568-7,0695=5,4985=5,50

Answer:

5.5 cm²

Step-by-step explanation:

Area of path = Area of path and the pool - area of pool

Area of pool = πr² = 3.14* 1.5 * 1.5 =7.065 cm²

Area of path along with pool:

Width of path =  50 cm  = 0.5 m

Here r = 1.5 + 0.5 = 2 m

Area of path along with pool = 3.14 * 2 * 2

                                                = 12.56 cm²

Area of path = 12.56 - 7.065 = 5.495 = 5.50 cm²

Last years freshman class at big state university totaled 5,305 students of those 1258 received a merit scholarship to help offs
Leokris [45]

Using the normal distribution, it is found that 95.15% of students receive a merit scholarship did not receive enough to cover full tuition.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The mean and the standard deviation for the amounts are given as follows:

\mu = 3456, \sigma = 478

The proportion is the <u>p-value of Z when X = 4250</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{4250 - 3456}{478}

Z = 1.66

Z = 1.66 has a p-value of 0.9515.

Hence 95.15% of students receive a merit scholarship did not receive enough to cover full tuition.
