Find the 8th term in the

sequence

-1/2,-1, -2, -4,...

Hint: Write a formula to help you.

1st term . Common Ratio desired term – 1)

**Answer:**

-64

**Step-by-step explanation:**

By looking at the numbers, we can identify that this is a geometric sequence and the ratio would be 2. The formula to find the nth term in a geometric series is:

[tex]t *r^{n-1}[/tex]

where t is the first term and r is the ratio. We can substitute in the information we know:

[tex]-\frac{1}{2} *2^{n-1}[/tex]

We are looking for the eighth term, so we substitute 8 where n is:

[tex]-\frac{1}{2}*2^{8-1}[/tex]

We can simplify:

[tex]-\frac{1}{2}*2^7[/tex]

[tex]-2^6[/tex]

[tex]-64[/tex]

A billing company that collects bills for doctors' offices in the area is concerned that the percentage of bills being paid by medical insurance has risen. Historically, that percentage has been 31%. An examination of 8,606 recent, randomly selected bills reveals that 32% of these bills are being paid by medical insurance. Is there evidence of a change in the percent of bills being paid by medical insurance

**Answer:**

Following are the responses to the given question:

**Step-by-step explanation:**

[tex]H_o : p =0.31\\\\H_a: p \neq 0.31\\\\n = 8606 \\\\ p^ = 0.32[/tex]

[tex]TS = \frac{(p^ - p)}{\sqrt{(\frac{pq}{n})}}[/tex]

[tex]= \frac{(0.32-0.31)}{\sqrt{(\frac{0.31\times 0.69}{8368})}}\\\\=\frac{0.01}{5.4}\\\\=0.00185\\\\[/tex]

Solve for x 5x - 10 = -10

**Answer:**

the answer is x = 0

**Step-by-step explanation:**

Cancel equal terms on both sides of the equation:

[tex]5x = 0[/tex]

Divide both side of the equation by 5.

[tex]x = 0[/tex]

Therefore, the answer is x = 0

**Answer:**

5x - 10 = -10

+10 +10

5x = 0

divide by 5 on both sides:

x = 0

Sarah's dad bought her a scooter that cost $89.95. He figures he can spend up to $30.05 on a helmet before he spends too much money in all. Let x represent how much money Sarah's dad wants to spend in all. Which inequality describes the problem?

Answer:

x - 89.95 ≤ 30.05= x ≤ 120

add 89.95 to both sides of the equation. Since on the right side 89.95 is already there it cancells eachother out leaving x. After adding 89.95 to 30.05 you should get an answer of 120.

The **money **Sarah's dad wants to **spend **in all if Sarah's dad bought her a scooter that costs $89.95, He can spend up to $30.05 on a **helmet**, which is **less **than or **equal **to $120, x ≤ 120.

**Inequality **is a **relationship **that compares two numbers or other mathematical expressions in an **unequal **way. Inequalities are the name given to certain algebraic mathematical **expressions**.

**Given**:

Sarah's dad bought her a scooter that cost $89.95,

He can spend up to $30.05 on a helmet,

Assume the x is the money Sarah's dad wants to spend in all,

Write the inequality as shown below,

x - 89.95 ≤ 30.05

Solve the inequality by adding 89.95 on both sides,

x - 89.95 + 89.95 ≤ 30.05 + 89.95

x ≤ 120

Ms jaegar can type 280 words in 4 minutes on her computer. If this is her average rate, How much word will she type in 10 minutes?

Show your work

**Answer:**

700 words

**Step-by-step explanation:**

280: 4

x:10

280/4 = x/10

4times x is equal to 4x and 280 times 10 is equal to 2800

4x=2800

2800 divided by x is 700.

The answer is 700 words per 10 minutes.

280x2=560. 8min

280/2= 140. 2min.

560+140=700. 10min.

Each quarter the marketing manager of a retail store divides customers into two classes based on their purchase behavior in the previous quarter. Denote the classes as L for low and H for high. The manager wishes to determine to which classes of customers he should send quarterly catalogs. The cost of sending a catalog is $15 per customer and the expected purchase depends on the customer’s class and the manager’s action. If a customer is in class L and receives a catalog, then the expected purchase in the current quarter is $20, and if a class L customer does not receive a catalog his expected purchase is $10. If a customer is in class H and receives a catalog, then his expected purchase is $50, and if a class H customer does not receive a catalog his expected purchase is $25. The decision whether or not to send a catalog to a customer also affects the customer's classification in the subsequent quarter. If a customer is class L at the start of the present quarter, then the probability he is in class L at the subsequent quarter is 0.3 if he receives a catalog and 0.5 if he does not. If a customer is class H in the current period, then the probability that he remains in class H in the subsequent period is 0.8 if he receives a catalog and 0.4 if he does not. Assume a discount rate of 0.9 and an objective of maximizing expected total discounted reward.

a) Formulate this as an infinite-horizon discounted Markov decision problem.

b) For ???? = 0.1, find a near-optimal policy using value iteration.

c) Find an optimal policy using policy iteration starting with the stationary policy which has greatest one-step reward.

d) Formulate the problem as a linear program, giving its primal and dual. Solve both and interpret the solutions.

**Answer:**

147 degrees

**Step-by-step explanation:**

all the angles of a triangle add up to 180 degrees. so, you must perform the operation 180-(83+64) which equals 33. this is the angle supplementary to angle 1. to find angle 1, you must subtract 180 and 33 since supplementary angles add up to 180 degrees. this is equal to 147 degrees.

A property has been assessed at $225 000. The mill rate is 14.5. To find the property tax, you would multiply the mill rate by: *

a) 0.10

b) 0.001

c) 0.01

d) 0.0001

A would be the answer

To find the** property tax**, you would multiply the mill rate by 0.01

To find the property tax, you would multiply the assessed **value** of the property by the mill rate.

Given that the assessed value is $225,000 and the** mill rate** is 14.5, we need to multiply these two values to calculate the property tax.

Property Tax = Assessed Value × Mill Rate

Property Tax = $225,000 × 14.5

To simplify the calculation, we can **convert **the mill rate to a decimal by dividing it by 1,000.

Mill Rate = 14.5 ÷ 1000 = 0.0145

Property Tax = $225,000 × 0.0145

Property Tax = $3,262.50

Therefore, to find the property tax, you would multiply the mill rate by 0.01 (option c).

Write one way of representing the equation of the given line in point-slope form. Then rewrite the equation in slope-intercept form.

answer:

step-by-step explanation:

points (0, 3) and (7, 4)

point-slope form = y - y1 = m(x - x1)

y - 3 = 1(x - 0)

just add y and x from either point to complete the form

slope-intercept form = y = mx + b

y = (0, -3)

m = 1

y = x - 3

x is the slope and -3 is the y-intercept

step-by-step explanation:

points (0, 3) and (7, 4)

point-slope form = y - y1 = m(x - x1)

y - 3 = 1(x - 0)

30 POINTS AND BRAINLIEST Alexis needs to paint the four exterior walls of a large rectangular barn. The length of the barn is 80 feet, the width is 50 feet, and the height is 30 feet. The paint costs $28 per gallon, and each gallon covers 420 square feet. What is the area of the barn Alexis needs to paint? ______________ Explain how you found your answer.

**Answer:**

It will cost $532 to paint the barn

**Step-by-step explanation:**

First we need to find the area of the barn's walls.

2 (length x height) + 2 (width x height)

=2 (80x30) + 2 (50x30)

=2 (2400) + 2(1500)

=4800+3000

=7800 ft^2

Now we can find the amount of gallons needed, then the total cost.

7800 ft^2/420 ft^2

=18.57 gallons

=19 gallons

19 gallons x $28

=$532

**Answer:**

520

**Step-by-step explanation:**

Area:

[tex]2(80*30) + 2(50*30) = 7800[/tex]
