Answer:

Binomial distribution

Step-by-step explanation:

For each processor, there is only two possible outcomes. Eithey they will require repair, or they will not. This means that we solve this problem using the binomial probability distribution.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Given the data shown below, which of the following is the best prediction for the number of years it will take for the populatio
aleksley [76]

We will have the following:

Using exponential regression we will have that the line of best fit will be:

f\mleft(x\mright)=8585.658603*1.399211892^x

Now, we will have that:

\begin{gathered} 300000=8585.658603*1.399211892^x\Rightarrow34.94199034=1.399211892^x \\  \\ \Rightarrow x=\frac{ln(34.94199034)}{1.399211892}\Rightarrow x= \end{gathered}

So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then

First correct response gets brainliest
Simora [160]

Answer:

x = 13

Step-by-step explanation:

This question is based on Secant Secant theorem.

Secant Secant theorem gives us the following formula:

(AB + BD)AB = (AC + CE).AC

From the above question we have the following parameters

AB = 5

BD = x

AC = 7.5

CE = 4.5

Hence,

(AB + BD)AB = (AC + CE).AC

(5 + x)5 = (7.5 + 4.5)7.5

25 + 5x = 90

Collect like terms

5x = 90 - 25

5x = 65

x = 65/5

x = 13
