Answer: 12,045 boxes
Step-by-step explanation:
120,450 divided by 10
= 12,045
Answer:
The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 99% confidence interval for the proportion of athletes who graduate is (0.5309, 0.7323).
equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
(1,-2) and slope of 1/3
y-(-2)=1/3(x-1)
general form is ax+by=c (or ax+by+c=0) where a,b,c are integers and a is positive
y-(-2)=1/3(x-1)
y+2=1/3(x-1)
times both sides by 3
3y+6=x-1
minus 3y both sides
6=x-3y-1
add 1 both sides
7=x-3y
x-3y=7
To get ax+by+c=0 form, subtract 7 from both sides to get
x-3y-7=0
Try
6.79 x 1.2
Then divide by two
Answer:
x=1/49, x=1
Step-by-step explanation:
part a:
so if (7^2)=49, you are left with 49x=1. we have to use inverse operations to isolate the variable x. this means we have to divide by 49 on both sides since 49 is multiplied with x. so, you are left with 1/49. x=1/49.
part b:
so according to the zero property, if you raise any number to the power of 0, you get 1. therefore, we are left with 1x=1. we can simplify this to x=1, which is the answer!
i think this is what you're asking for, if i misunderstood please comment under my response!
