danielle wants to know how fast her rose garden will grow. Right now, her roses are 3 3/8 inches tall. If her roses grow 5/8 of

KATRIN_1 [288]

Answer: The answer is minimum 33 days.

Step-by-step explanation: Given that Daniel has a beautiful rose garden and she wants to know how fast her rose garden will grow. Also given that

Height of her roses at present is given by

$h_p=3\dfrac{3}{8}=\dfrac{27}{8}~\textup{inches}.$

And, height of the roses that increases each day is

$h_d=\dfrac{5}{8}~\textup{inches}.$

We need to find the number of days in which her roses will be a height of minimum 24 inches.

Let, 'x' be the number of days taken by the roses to be minimum 24 inches tall.

So, we have

$h_p+h_dx\geq 24\\\\\Rightarrow \dfrac{27}{8}+\dfrac{5}{8}x\geq 24\\\\\Rightarrow 27+5x\geq 192\\\\\Rightarrow 5x\geq 165\\\\\Rightarrow x\geq 33.$

Thus, the roses will take minimum of 33 gays attain a height of no less than 24 inches.

In January of 2003(group 1), 1188 out of 1500 spots were bare ground (no vegetation). Find the sample proportion of bare ground

Nikitich [7]

Answer:

$n= 1500$ represent the random sample selected

$X= 1188$ represent the number of pots that were bare ground (no vegetation

$\hat p=\frac{X}{n}$

And replacing we got:

$\hat p=\frac{1188}{1500}= 0.792$

So then the sample proportion of bare ground spots is 0.792 for this sample

Step-by-step explanation:

We have the following info given from the problem:

$n= 1500$ represent the random sample selected

$X= 1188$ represent the number of pots that were bare ground (no vegetation)

And for this case if we want to find the sample proportion of bare ground spots we can use this formula:

$\hat p=\frac{X}{n}$

And replacing we got:

$\hat p=\frac{1188}{1500}= 0.792$

So then the sample proportion of bare ground spots is 0.792 for this sample
