Answer:
x = 70
Step-by-step explanation:
14 + x = 84
x= 84 - 14
x = 70
here x is the games lost.

42/558 is what you write to show the expression 42 divided by 558
A 99% confidence interval for the population mean of high school students that take the bus to school every day is b) ci=(44.34%, 54.43%)
We need to find the 99% confidence interval for the population mean of high school students that take the bus to school everyday
A confidence interval is a range of estimates for an unknown parameter. The confidence interval is calculated at the specified confidence level; the most common is the 95% confidence level, but sometimes other levels are used, such as 90% or 99%.
The confidence interval of proportions is given by:
π ± z √(π (1-π) /n)
π is the sample proportion.
z is the critical value.
n is the sample size.
For 99% confidence interval the value of z is 2.58
π = 321/650
The confidence interval is given by
=321/650 ± 2.58 √( (321/650) × [ 1 - (321/650) ] ÷ 650)
= (0.493846 ± 0.050594)
=(0.4434 , 0.5443)
=(44.34 % , 54.43 %)
Hence a 99% confidence interval for the population mean of high school students that take the bus to school every day is ci=(44.34%, 54.43%)

Answer:
$256
Step-by-step explanation:
Each class got $256. I know this because I did 3,840 divided by 15 which got me the CORRECT answer of $256
The only two points that I can clearly see are (0,2) and (5,3).
The slope is (y2-y1)/(x2-x1), in this case:
m=(3-2)/(5-0)=1/5
So the slope of the line is 1/5
