Answer:
44
Step-by-step explanation:
to find circumference of a circle you need to multiple r (7 in here) with 2 and pi
therefore the answer is : 2x7x3 = 42 or 44 approximately
Answer:
1 / 18
Step-by-step explanation:
Odds = 1 : 17
Probability = odd * (17 ÷ sum of odd ratio)
Sum of odd ratio = ( 1 + 17) = 18
= (1 / 17) * (17 / 18)
= 1 / 18
Answer:
There is no enough evidence to reject the claim using a level of significance of 5%
Step-by-step explanation:
Let p be the true proportion of homeowners in Omaha who own a lawnmower. We want to test
vs 
(two-tailed alternative).
We have a large sample of size n = 500 and a point estimate for p is 
. The test statistic is given by
where 
is the standard error of 
when 
is true. The observed value is 
= 1.4064 which comes from a standard normal distribution. Because we want to use a level of significance of 5%, our rejection region is RR={z | z < -1.96 or z > 1.96} where -1.96 and 1.96 are the 2.5th and 97.5th quantiles respectively. Because 1.4064 does not belong to RR, we fail to reject the null hypothesis.

Answer:
x intercept is 8
y intercept is 4
Step-by-step explanation:
x-intercept -> format is (x, 0)
We know that y=0, so we can substitute that in and solve for x to find the x-intercept. x-2y = x - 2(0) = x = 8. Therefore, the x-intercept is 8.
y-intercept -> format is (0, y)
We know that x=0, so we can substitute that in and solve for y to find the y-intercept. x-2y = 0 - 2y = 2y = 8 -> y =4. Therefore, the y-intercept is 4.
I hope this helps! :)
