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
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

Californians use 75 BTU of energy per home per year which is 25% less than the national average.
How many BTU does an average American household use? Show Work
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)
Thus, the national average use of energy is expected to be 100 BTU.

In the parallelogram above, AE = 7x+4, BE=15x-12, and DE= 9x. What is the length of BD?
Answer:
BD = 36
Step-by-step explanation:
• the diagonals of a parallelogram bisect each other , so
BE = DE , that is
15x - 12 = 9x ( subtract 9x from both sides )
6x - 12 = 0 ( add 12 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Then
BD = BE + ED
= 15x - 12 + 9x
= 24x - 12 ( substitute x = 2 )
= 24(2) - 12
= 48 - 12

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.

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.
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

*Note: you must use these exact conversion factors to get this question right.
1 cup (cup) = 8 fluid ounces (fl oz)
1 liter (L) 1000 milliliters (mL)
1 pint (pt) = 2 cups (cups)
1 cubic meter (m³) = 1000 liters (L)
1 quart (qt) = 2 pints (pt)
1 gallon (gal) = 3.785 liters (L)
1 gallon (gal) = 4 quarts (qt)
1 fluid ounce (fl oz) = 29.574 milliliters (ml)
1 cubic foot (ft³) = 7.481 gallons (gal)
Answer:

how to graph y=2x+1
-2x=y=-2
Answer:
For y=2x+1
The line y=2x+1 has a y-intercept of +1, so begin with a point at (0,1)
and its slope is 2/1, which means from there you go Up 2 and Right 1.
Follow that pattern until you can draw a straight line through all the points.
For -2x=y=-2
In this point it only passes (0,2) and (1.0)
Have a wonderful day! :-)
