There are 98,515 tress at Washington Park.If there are 85 acres of land,and the trees spread out evenly,how many trees are there

aksik [14]

To answer this all we need to do is DIVIDE.

98515 ÷ 85 = 1159

CHECK OUR WORK

1159 × 85 = 98515

So, we were right!! :)

So, there would be 1159 trees on each acre.

Hope I helped ya!!

IQ scores are measured with a test designed so that the mean is 116 and the standard deviation is 16. Consider the group of IQ s

butalik [34]

Answer:

So the z-scores that separate the unusual IQ scores from those that are usual are Z = -2 and Z = 2.

The IQ scores that separate the unusual IQ scores from those that are usual are 84 and 148.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 116, \sigma = 16$

What are the z scores that separate the unusual IQ scores from those that are usual?

If Z<-2 or Z > 2, the IQ score is unusual.

So the z-scores that separate the unusual IQ scores from those that are usual are Z = -2 and Z = 2.

What are the IQ scores that separate the unusual IQ scores from those that are usual?

Those IQ scores are X when Z = -2 and X when Z = 2. So

Z = -2

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

$-2 = \frac{X - 116}{16}$

$X - 116 = -2*16$

$X = 84$

Z = 2

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

$2 = \frac{X - 116}{16}$

$X - 116 = 2*16$

$X = 148$

The IQ scores that separate the unusual IQ scores from those that are usual are 84 and 148.

The height that a ball bounces varies directly with the height from which it is dropped. A certain ball bounces 30 cm when dropp

Akimi4 [234]

The ball will bounce 72 cm high if dropped from a height of 120 cm

Solution:

Given, The height that a ball bounces varies directly with the height from which it is dropped.

A certain ball bounces 30 cm when dropped from a height of 50 cm.

We have to find how high will the ball bounce if dropped from a height of 120 cm?

Now, according to given information,

When dropped from 50 cm ⇒ bounces 30 cm

Then, when dropped from 120 cm ⇒ bounces "n" cm

Now by Chris cross method, we get,

$\begin{array}{l}{n \times 50=30 \times 120} \\\\ {\rightarrow n=\frac{30 \times 120}{50}} \\\\ {\rightarrow n=\frac{3600}{50}} \\\\ {\rightarrow n=72}\end{array}$

Hence, the ball bounces 72 cm high.
