Answer:
probability = 0.9286
Step-by-step explanation:
given data
mean = $8.30
standard deviation = $4.70
waits parties over a weekend of work = 60
solution
when we earn at least $550 in 60 parties
so average per party will be x = 
average x = 9.1667
so now we get here z value that is
...............1
put here value and we get
z = 
z = 0.184404
so
P(x>9.1667) = P(z>0.184404)
use standard normal table
probability = 1 - 0.0714 = 0.9286
Answer:
A'(5.5, -4.2), B'(7.5, -9.2), C'(3.5, -3.2)
Step-by-step explanation:
I really do hope I understood you correctly. I figured that the rule would have to be added to each point. If those are wrong, try subtracting the rule.
Again, I'm not trying to take your points and leave you with a wrong answer. I really did give it my best.
55 mph minus 40 mph = 15 miles distance for each hour
So 5 hours * 15 = 75 miles difference after 5 hours
The area of a circle with respect to its diameter is:
A=(πd^2)/4
If he plants roses in every other section, there will be half of the area remaining, so half of the area of the circle is:
A=(πd^2)/8, since d=8:
A=(64π)/8 m^2
A=8π m^2 and if you want an approximation:
A≈25.13 m^2 (to nearest hundredth of a square meter)
Solution
1) Simplify
<span> to </span>
<span>−2= </span>
+
2) Simplify
+
<span>to <span>914</span>
</span>
<span>−2= </span>
3) <span>Add 2 to both sides
</span>
=
<span>+2
</span>
4) Simplify
<span><span>+2</span> to </span>
=
5) <span>Multiply both sides by 7
</span><span>4y= </span>
<span>×7
</span>
6) Simplify
<span><span>×7</span> to </span>
=
7) Simplify
<span> to </span>
=
8) <span>Divide both sides by 4
</span>y=
<span>×4
</span>
9) <span>Simplify <span>2×4</span> to 8
</span><span>y=</span>
<span><span>
Hope this helps
