Answer:
$8.75
Step-by-step explanation:
Create a proportion where x is the cost for 7 bags:
= 
Cross multiply and solve for x:
4x = 35
x = 8.75
So, the cost of 7 bags is $8.75
Answer:
it is 50.27
Step-by-step explanation:
the formula for finding the area it
A= pi r^2
pi=3.14
so that being said you want to:
you want to divide the diameter by 2 to get 4,then you want to do 4^2 to get 16. then multiply 16 by 3.14 to get 50.265 then you want to round up to 50.27
Answer:
$102
Step-by-step explanation:
We need to build a system of equations for this question.
I am going to call x the value Lawson will pay to Expert Card, y the value he will pay to passport and z the value he will pay to US Speedy.
He will pay $612 in all, so x+y+z = 612.
He will pay 5 times as much to Expert Card as US Speedy, so x = 5z.
The passport payment will be only 20% of the total of the other two payments. So y = 0.2(x+z).
Now we have the following system of equations:
1)x+y+z = 612
2)x = 5z
3)y = 0.2(x+z)
And we need to find y.
I will put 2) and 3) at 1). We end up with:
5z + 0.2(5z+z)+z = 612
5z + 1.2z + z = 612
7.2z = 612
z = $85
Knowing z, now we can find y at 3)
y = 0.2(x+z)
y = 0.2(5z+z)
y = 1.2z
y = 1.2(85)
y = $102
Lawson will pay $102 towards the passport credit balance.
The <em>correct answer</em> is:
The mean for July is smaller than the median; and
the mean for August is larger than the median.
Explanation:
A distribution with a positive skew would have a longer whisker in the positive direction than in the negative direction. A larger mean than median would also indicate a positive skew.
Alternatively, a distribution with a negative skew would have a longer whisker in the negative direction than in the positive direction. A smaller mean than median would also indicate a negative skew.
The whisker in the negative direction for July is longer than the whisker in the positive direction. This indicates a negative skew.
The whisker in the positive direction for August is longer than the whisker in the negative direction. This indicates a positive skew.
