You didn't specify how big the festival is. so i can't find the answer.....but i will try
first let's devide 10,000 by 0.9 to see how many square metres we need, to fit 10,000 people
10,000÷0.9=11,111 square meters
we need atleast 11,111 meters of land for a safe festival

The vertex angle of isosceles triangle is 110. what are the measures of the base angles

alexgriva [62]

Two sides are equal in an isosceles triangle. This means that the angle both sides make with the third side must be the same. Since the angles in a triangle add up to 180°, you can subtract 110° from 180° and divide your answer by two. The resulting number will be the measure of each of the two unknown angles

Suppose the number of free throws in a basketball game by one player are normally distributed with a standard deviation 0.97 fre

babunello [35]

Answer: 1.960

Step-by-step explanation:

The value of z we use to calculate a confidence interval with a ( $1-\alpha$ ) confidence level is a two-tailed test value i.e. represented by :-

$z_{\alpha/2}$

Given : The level of confidence: $1-\alpha=0.95$

Then, significance level : $\alpha: 1-0.95=0.05$

With the help of standard normal distribution table for z , we have

$z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.960$

Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960

Lydia spent 4/5 of her money on a mobile phone and 2/3 of the remaining amount on a bag. She had $60 left. How much more money d

KengaRu [80]

The answer is 600 because 1 out 3 is 60 so to find the bag multiply by two while to find 1 out 5 of her monet take 60 times 3 which is 180. 180 times 4 is the money she spent on her mobile phone so take the money spent on her mobile phone(720)minus the amount of money spent on the bag(120)
