Answer:
The sigma notation would look like this:
∞
Σ 48(1/4)^i-1
i = 1
Step-by-step explanation:
I can't seem to find a good way to make it more connected so I'll just have to tell you. The ∞ is above the ∑, while the i = 1 is under it. That is all one thing. The rest is followed as normal, and it is all next to the ∑
Answer:
r=2
Step-by-step explanation:
Divide diameter by 2 since the diameter is half of radius
4/2=r
r=2
Here is the solution based on the given problem above.
Given: Area of the piece of paper = 84 square inches
Width = 10 1/2 or 10.5 inches long
? = length of the piece of paper
To find the area of an object, the formula would be A= L x W
Now, let's substitute the given values above
84in2 = L(10.5in)
Now, divide both sides with 10.5 and we get 8.
L = 8 inches.
Therefore, the length of the paper is 8 inches.
Hope this solution helps.
Answer: a) 0.8665
b) 0.8190
Step-by-step explanation:
Given : The partial pressure of oxygen PaO2 is a measure ofthe amount of oxygen in the blood. Assume that the distribution ofPaO2 levels among newborns has a 
38 mmHg and 
9 mmHg.
If we take a random sample n= 25 newborns, then using formula 
, we have
At x= 36
At x= 41
Using table for z-values, the probability that the sample mean will be greater than 36 :
The probability that the sample mean will be between 36 and 41 :-
Answer:
$2600
Step-by-step explanation:
If his monthly salary is $2000 and 2% commission.
He made $30,000 in sales for the month so lets make an equation.
s = total salary
s = $2,000 + .02($30,000)
s = $2,000 + $600
s = $2600
Randy's salary for the month is $2600.
