Mean = 5+11+8+8+7+4+10+9+7+7+6 divided by the number of observations which is 10
Therefore, 73/10
Mean= 7.3

Ratling [72]

Answer:

Recursive formula:

$P_{n} = (1.15)P_{n-1}$

P(0) = 200

1070 speeding tickets are predicted to be issued in 2025

Step-by-step explanation:

The number of speeding tickets in an year, in function of the number in the previous year, can be given by the following formula:

$P_{n} = (1+r)P_{n-1}$

In which $P_{n-1}$ is the number of tickets issued in the previous year and r is the rate the number of tickets increase.

Every year thereafter, the number of speeding tickets issued is predicted to grow by 15%

So r = 0.15 and

$P_{n} = (1.15)P_{n-1}$

During the year 2012, Middletown issued 200 speeding

So P(0) = 200.

Then the recursive formula is:

$P_{n} = (1.15)P_{n-1}$

P(0) = 200

Write the explicit formula for P n P n = If this trend continues, how many speeding tickets are predicted to be issued in 2025?

2025 is 13 years after 2012.

So this is P(12).

We can expend the equation in the following format

$P(12) = (1.15)^{12}P(0) = (1.15)^{12}*200 = 1070$

1070 speeding tickets are predicted to be issued in 2025

Answer:

$18c - 30d + 36$

Step-by-step explanation:

Given

$6(3c - 5d + 6)$

Required

Expand

$6(3c - 5d + 6)$

Open bracket

$6(3c - 5d + 6) = 6*3c - 6*5d + 6*6$

$6(3c - 5d + 6) = 18c - 30d + 36$

So, the result of the expression is:

$18c - 30d + 36$

The scatter plot below can be used to find the approximate rate at which water flows through a garden hose. The line of best fit

creativ13 [48]

Answer:

$36\ \text{gallons per unit}$ will flow from the hose in 45 minutes.

Step-by-step explanation:

The line of best fit for the scatter plot can be described by the equation :

$y=\dfrac{4}{5}x$

y is amount of water in gallons

x is time

When x = 45 minutes, put x = 45 in above formula as :

$y=\dfrac{4}{5}\times 45\\\\y=36\ \text{gallons per unit}$

So, $36\ \text{gallons per unit}$ will flow from the hose in 45 minutes.
