Answer:

21 grapes.

Step-by-step explanation:

We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.

First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.

$\text{Grapes eaten by Tyrell}=2\times 6$

$\text{Grapes eaten by Tyrell}=12$

Now, we will find half of 6 to find number of grapes eaten by Lucy.

$\text{Grapes eaten by Lucy}=\frac{6}{2}$

$\text{Grapes eaten by Lucy}=3$

$\text{Grapes eaten by them in all}=6+12+3$

$\text{Grapes eaten by them in all}=21$

Therefore, the three of them eat 21 grapes in all.

iVinArrow [24]

Answer: 20

Step-by-step explanation:

Formula to find the sample size : $n=(\dfrac{\sigma\times z_{\alpha/2}}{E})^2$

Given : Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Margin of error : $E$

Standard deviation: $\sigma=\text{ 4.5 hours}$

Then, we have

$n=(\dfrac{4.5\times(1.96)}{2})^2=19.4481\approx20$

Hence, the minimum sample size must be 20.
