A 7,000-seat theater is interested in determining whether there is a difference in attendance between shows on Tuesday evening and those on Wednesday evening. Two independent samples of 33 weeks are collected for Tuesday and Wednesday. The mean attendance on Tuesday evening is calculated as 5,300, while the mean attendance on Wednesday evening is calculated as 5,700. The known population standard deviation for attendance on Tuesday evening is 490 and the known population standard deviation for attendance on Wednesday evening is 480. Which of the following is the value of the appropriate test statistic?

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
