A stadium has a seating capacity of 15400.

a) calculate the number of people in the stadium when 75% of the seats are occupied.

b) the stadium is to be renovated with the new seating capacity of 20790 seats. After the renovation, what will be the percentage increase in the number of seats?

The number of people is 11550 and the percentage increase is 35%.

When 75% of the seats are occupied and the stadium has a seating capacity of 15400, the number of people will be:

= 75% × 15400

= 11550

The percentage increase after innovation will be:

= (20790 - 15400) / 15400 × 100

= 35%

a) 11550

b)35%

Step-by-step explanation:

Hi, to answer this question, first, we have to multiply the stadium capacity by the percentage in decimal form (75/100)

a)15400 x (75/100) = 11,550

For b), we know that 15400 is the 100% of the capacity, so, for 20790 the percentage will be:

15400/100= 20790/x

Solving for x

x= 20790 / 154

x= 135%  

135%-100% = 35%

The percentage increase in the number of seats will be 35%

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
