The picture in the attached figure
we know that
area of the <span>the shaded region=area of rectangle -area of a kite
area of rectangle=(3x+x)*(x+x)----> 4x*2x---> 8x</span>²
area of a kite=(1/2)*[d1*d2]
where d1 and d2 are the diagonals
d1=4x
d2=2x
so
area of a kite=(1/2)*[4x*2x]----> 4x²
area of the the shaded region=8x²-4x²-----> 4x²
the answer is 4x²
2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
Answer:
Step-by-step explanation:
-5f=-3(8-f)
Opening bracket
-5f = - 24 + 3f
Collecting like terms
-5f - 3f = -24
-8f = -24
Dividing by -8
f = -24/-8
f = 3
Answer: H
The first step is dividing 4 from both sides to find what m equals. By the way, its the <u>only</u> step :D
Answer:
There is a significant difference between the means of the two population
Step-by-step explanation:
The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.
Range = 140 - 75 = 65
The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.
Range = 183 - 96 = 87
Difference in mean = 104 - 85 = 19
If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence
But by considering the mean difference and the value of range, we can say that
There is significant difference between the means of the two population
