on a drive from your home to town, you wish to average 64 mph. the distance from your home to town is 88 miles. however, at 44 miles (half way), you find you have averaged only 48 mph. what average speed must you maintain in the remaining distance in order to have an

Answers

The average speed must you maintain in the remaining distance in order to have an overall average speed of 33.6 mph is 50.39 mph.

We have to find the average speed must you maintain in the remaining distance in order to have an overall average speed of 33.6 mph.

Let the speed be x.

The total average we want = 33.6 mph

The distance from your home to town = 90 miles

Time = Distance/Speed

Time = 90/33.6

At 45 miles (half way), you find you have averaged only 25.2 mph. So

Time first leg = 45/25.2

Time second leg= 45/x

Now the average speed;

45/25.2 + 45/x = 90/33.6

Subtract 45/25.2 on both side, we get

45/x = 90/33.6 - 45/25.2

After solving the ratio, we get

45/x = 0.893

Multiply by x on both side, we get

0.893x = 45

Divide by 0.893 on both side, we get

x = 45/0.893

x = 50.39 mph

in a sample of 2000 people, 430 people have their ears pierced. two unrelated people are selected at random without replacement, find the probability that neither of the people have their ears pierced.

Answers

The probability that neither of the people have their ears pierced is 0.6157

What is the probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain.

The probability of A happening is the number of people who do not have their ears pierced divided by the total number of people in the sample, which is:

P(A) = (2000 - 430) / 2000 = 1570 / 2000 = 0.785

The conditional probability of B given A is the number of people who do not have their ears pierced and are still available to be selected as the second person divided by the total number of people available to be selected as the second person, which is:

P(B|A) = (2000 - 430 - 1) / (2000 - 1) = 1569 / 1999 = 0.7845

Therefore, the probability that neither of the people have their ears pierced is:

P(A) * P(B|A) = 0.785 * 0.7845 = 0.6157

Hence, the probability that neither of the people have their ears pierced is 0.6157

Answers

The two missing positive numbers are; 50/3 and 200/3

How to solve algebra word problems?

The difference between two positive numbers is 50. Let the two numbers be x and y and as such we have;

x - y = 50   -----(1)

One number is four times the other number. Thus;

x = 4y  -----(2)

Put 4y for x in eq 1 to get;

4y - y = 50

3y = 50

y = 50/3

Thus;

x = 4(50/3)

Formulate an IP to minimize the number of fulltime employees who must be hired, and solve it using Excel Solver to find the optimal solution

Answers

Here is a simple framework to model the problem as an Integer Programming (IP) problem and solve it using Excel Solver:

Define decision variables:

Let x(i,j) be the number of full-time employees assigned to work on day i (1 <= i <= 7) and given day off on day j (1 <= j <= 7).

Set constraints:

a. Work days constraint: For each day i, the number of employees working must meet the demand:

∑(j=1 to 7) x(i,j) = demand(i) (1 <= i <= 7)

b. Availability constraint: Each employee can work only 5 consecutive days, so for each day j (1 <= j <= 7), the number of employees given day off on day j must be less than or equal to the number of employees working on day j-5:

∑(i=1 to 7) x(i,j) <= ∑(i=j-5 to j-1) x(i,j-5) (1 <= j <= 7)

Set objective:

The objective is to minimize the total number of full-time employees hired, so the objective function is:

minimize: ∑(i=1 to 7) ∑(j=1 to 7) x(i,j)

Solve using Excel Solver:

Excel Solver can be used to find the optimal solution to the IP problem. The constraints and objective function should be set up in the spreadsheet, and Solver should be configured to use the integer constraint option. The solution will give the optimal number of full-time employees hired and their assignment on each day.

How many BTU does an average American household use? Show Work

Answers

Proportionately, an average American household uses 100 BTU of energy per home per year while Californians use 75 BTU, which is 25% less than the national average.

What is the proportion?

Proportion refers to the ratio or relative size of a value or number compared to another.

Proportions are fractional values equated to each other.

Generally, proportions may be depicted as fractions, decimals, or percentages.

The level of energy per home per year in California = 75 BTU

The national average of BTU use = 100%

California's use = 75% (100 - 25)

Proportionately, if 75% = 75 BTU, 100% = 100 BTU (75/0.75)

So, each exterior angle can be calculated as, 180 - (n - 2) 180°/n

Now, let us put the number of vertices into these formulae,

Each interior angle = (45 - 2)×180°/45 = 43×180°/45 = 172°

Answers

The approximate probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average is 0.019

We can use the normal distribution to approximate the probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average.

To do this, we have to standardize the variable by subtracting the mean and dividing by the standard deviation.

In this case, X = (50 - 37) / hours = 1.83

We know that for a standard normal distribution, the probability of X being less than a certain value can be found using a standard normal table or a calculator with a built-in standard normal cumulative distribution function (CDF).

Now, we will use the cumulative distribution function to find the probability of less than 10 out of 200 working more than 50 hours a week on average. Using a standard normal table or calculator, we can find the probability of having X < -2.04.

P(X < -2.04) = 0.0188

So the approximate probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average is 0.0188 which rounding it off to the third decimal place we get 0.019.

Tank A has a capacity of 9.5 gallons. 6 1/3 gallons of the tanks water are poured out. How many gallons of water are left in the tanks

Answers

The volume of water that are left in the tank is equal to 3.2 gallons.

How to calculate the volume of a geometric figure?

Mathematically, the volume of a cuboid tank is a measure of its capacity and it can be calculated by using this following formula:

Volume of a tank = L × W × H

Where:

L represents the length of a cuboid tank.W represents the width of a cuboid tank.H represents the height of a cuboid tank.

In order to determine the quantity (volume) of water that are left in the tank, we would use this mathematical expression:

Volume of water left = capacity of tank A - volume of water poured

Volume of water left = 9.5 gallons - 6 1/3 gallons

Volume of water left = 9.5 gallons - 6.3 gallons

Answers

The number of bean plants should she plant will be 60

t = tomato plants

b = beans

To Solve by using system of equations

Clear any fractional coefficients if there are any. Alternate the coefficients of a single variable. Select the variable you want to remove. Multiply one or both equations to make the variable's coefficients opposite.

Total plants = 100

t + b = 100     {equation 1}

20 more tomatoes than beans

t = b + 20       {equation 2}

b + 20 + b = 100

2b + 20 = 100

Finish solving for b to find a number of beans.

Then tomatoes will be b+20

Putting this in equation 1

b+20+b=100

2b+20=100

b=40

then t= b+20  {equation 2}

t=60

Hence the number of bean plants should she plant will be 60
