Answer:
x=5
Step-by-step explanation:
The square measures 14 by 14
so the area = 14 x 14 = 196 square inches
Double the area:
196 x 2 = 392 square inches
To find one side of the square:
= 19.80 inches (2 d.p.)
so the area = 14 x 14 = 196 square inches
Double the area:
196 x 2 = 392 square inches
To find one side of the square:
Answer:
No, does not differ.
Step-by-step explanation:
Given that there are two intersections route 7 and route 62.
At the intersection of Route 7 and North Shrewsbury in Clarendon, Vermont, 154 vehicles were observed to encounter a yellow light in the indecision zone, and 21 of them ran the red light. At the intersection of Route 62 and Paine Turnpike in Berlin, Vermont, 183 vehicles entered the intersection in the indecision zone, and 20 ran the red light.
Let p1 be the first proportion and p2 the second
We want to test whether these two proportions differ
(two tailed test at 5% significance level)
test statistic =
Z statistic =
p value = 0.4473
Since p >0.05 accept null hypothesis.
There is no significant difference and the proportion of redlight runners does not differ between the two intersections
