Jayce is a taxi driver

erastovalidia [21]

Answer:

Jayce's fee for his $10^{th}$ drive is equal to $K$ dollars.

Step-by-step explanation:

$M(n)$ models Jayce's fee (in dollars) for his $n^{th}$ drive on a certain day.

Substitute $n=10,$ then

$M(10)$ models Jayce's fee (in dollars) for his $10^{th}$ drive on a certain day.

This means Jayce's fee for his $10^{th}$ drive is equal to $K$ dollars.

Find the measure of angle A

Westkost [7]

Answer:

35 degrees

Step-by-step explanation:

Sum of angles inside a triangle is 180 degrees.

Right angle is 90 degrees.

180 = 90 + (x + 46) + (x + 66) = 2x + 202

x = -11

A = x + 46 = -11 + 46 = 35

Need help wasn't there for a lesson

These are linear equations, so there is x and y. On number one the first thing they plotted was (3,8) so in a function table the 3 would be on the left side and the 8 would be on the right side. I’ll leave you with the rule of the first one, if the rule is times 2 plus to the how would you put it in a function table.

The first thing that you would put into the function table on the first question would be as I said earlier 3 and then 8. The rule is the rate. Using a function table will be very helpful (That’s why I keep mentioning one). Let me know if this helps.

SAT scores have a mean of 1026 and a standard deviation of 209. ACT scores have a mean of 20.8 and a standard deviation of 4.8.

Y_Kistochka [10]

Answer:

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

Step-by-step explanation:

Mean SAT scores = 1026

Standard Deviation = 209

Mean ACT score = 20.8

Standard Deviation = 4.8

We are given SAT and ACT scores of a student and we have to compare them. We cannot compare them directly so we have to Normalize them i.e. convert them into such a form that we can compare the numbers in a meaningful manner. The best way out is to convert both the values into their equivalent z-scores and then do the comparison. Comparison of equivalent z-scores will tell us which score is higher and which is lower.

The formula to calculate the z-score is:

$z=\frac{x-\mu}{\sigma}$

Here, μ is the mean and σ is the standard deviation. x is the value we want to convert to z score.

z-score for junior scoring 860 in SAT exam will be:

$z=\frac{860-1026}{209}=-7.59$

z-score for junior scoring 16 in ACT exam will be:

$z=\frac{16-20.8}{4.8}=-1$

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.
