Answer:
The claim can be determined by the probability method which will determine the percentage of battery lasting to an average of 16 hours.
Step-by-step explanation:
Probability method in statistics helps to determine the percentage of an event in certain circumstances. In the given scenario the claim is made that battery lasts an average of 16 hours. This claim can be verified by the probability check though standard deviation from the observation.
To solve for surface area of a sphere, the formula is 4*pi*r^2 where "r" is the radius. Since we know the diameter and that it is the length across the sphere, and that the radius is the distance from the center to the edge, we can divide the diameter by 2 to get the radius. This shows the radius is 5. Now all we have to do is substitute in the 5 for the "r" and solve.
SA=4*pi*r^2
SA=4*pi*5^2
SA=314.159
We are rounding to the hundredth here, so we can say the surface area of the sphere is (A) approximately 314.16 square miles.
Answer:
Formula for nth term in Arithmetic sequences is:
![a_n =a+(n-1)d](https://tex.z-dn.net/?f=a_n%20%3Da%2B%28n-1%29d)
where a is the first term, d is the common difference and n is the number of terms.
As per the statement:
The rule for the pattern is add 4.
As the first term in line says the first term i,e 7
![a= 7](https://tex.z-dn.net/?f=a%3D%207)
common difference(d)= 7
As the Jenna number is 8th in line.
Series we get;
7, 11, .........![a_8](https://tex.z-dn.net/?f=a_8)
We have to find the 8th term.
n = 8, a = 7 and d = 4
Using above formula:
![a_8 = 7+(8-1)4 = 7+7 \cdot 4 = 7 +28 = 35](https://tex.z-dn.net/?f=a_8%20%3D%207%2B%288-1%294%20%3D%207%2B7%20%5Ccdot%204%20%3D%207%20%2B28%20%3D%2035)
Therefore, 35 number should Jenna say.
