IGNORE WORK ON PAPER PLS HELP3. A game at an arcade consists of a balloon that is inflated little-by-little during each round of play. The player wins. when the balloon pops. The amount of air (in cubic inches) that is needed to make the balloon pop can be modeled by a uniform distribution on the interval from 25 to 35 cubic inches of air. (a) Draw a density curve to model the amount of air that is needed to make the balloon pop. Be sure to include scales on both axes. (b) About what percent of the time will the balloon pop upon receiving at most 28 cubic inches of air? (c) Find the first quartile (Q1) of this distribution. 4. The manager of the arcade wants to know how quickly players switch from one game to another. After conducting a study, he concludes that the amount of time that people spend playing a game before switching to a different game can be modeled by a normal distribution with mean 2.1 minutes and standard deviation 0.4 minutes. Sketch the normal density curve. Label the mean and the points that are 1, 2, and 3 standard deviations from the mean.

Answers

convert 12 feet and 5 inches to inches
1 foot=12 inches
12 feet times 12=144 inches
144+5=149 inches

Find the given term 11, -33,99 9th term

Answers

Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is $a_n=-11\cdot(-1)^n\cdot3^(n-1)$

So, the 9th term is
$a_9=-11\cdot(-1)^9\cdot3^(9-1)=-11\cdot(-1)\cdot6561=72171$

Brew Ha Ha & Tea Co. produces two types of coffee blends: Moring (x) and (y). The Morning Blend has 9 oz of Guatemalan coffee and 7 oz of Brazilian coffee, and the house blend has 6 oz of Guatemalan coffee and 10oz of Brazilian coffee. The company makes $2 in profit from each bag of the morning blend sold and $2.50 in profit from each bag of house blend sold. The company has 400 oz of both the Guatemalan and Brazilian coffees available. This set of inequalities represents the constraints in this situation. 9x + 6y< 400 7x + 10y<400 x > 0 y > 0 The company wants to maximize their profits using the objective function P = 2x + 2.5y What is the maximum profit? there is a chart for vertex and objective function

Answers

From the graph of the constraints, the corner points are: (0, 0), (0, 40), (33.33, 16.67), (44.44, 0)

For the corner points the profits are:
For (0, 0): P = 2(0) + 2.5(0) = 0
For (0, 40): P = 2(0) + 2.5(40) = 0 + 100 = 100
For (33.33, 16.67): P = 2(33.33) + 2.5(16.67) = 66.66 + 41.68 = 108.34
For (44.44, 0): P = 2(44.44) + 2.5(0) = 88.88

Therefore, the maximum profit is $108.34

The amount of time needed to complete a certain road trip, t, varies inversely with the speed of avehicle, s. At a speed of 68 miles per hour, the trip will be complete in 15 hours. What would the
speed of the car have to be to complete the trip in 17 hours?

Answers

The speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

What is speed?

The rate of change of position of an object in any direction is called speed.

How do you calculate speed when distance and time is given?

$speed = (distance)/(time)$

According to the given question

At a speed of 68 miles per hour, the trip will be complete in 15 hours.

⇒ Total distance covered in 15 hours = 68 × 15 = 1,020 miles

( because, distance = speed × time)

Therefore, the speed of car to complete the trip in 17 hours

= $(1020)/(17) =60miles/hr$

Hence, the speed of car must be 60mile/hour, so that the trip will complete in 17 hours.

Answer:

x = 60

Step-by-step explanation:

t = $(k)/(x)$

15 = k/68

k=1020

~~~~~~~~~~~

17 = 1020/x

x = 1020/17

x = 60
