Math Problem 1: What is the total area of Xavier’s lot?
Use the formula for calculating the area of a trapezoid to help answer your question:
A= a+b2c or front of lot + back of lot/2
Once Bradley has the total area of the lot, he explains to Xavier that the county only allows for 40 percent of any lot to be covered with buildings.
Math Problem 2: What is Xavier’s available lot coverage? (In other words, how big a house can he build?)
Use the formula for calculating percentage to help answer your question:
40/100 = x/Total Area.
Problem 1:
To find the area you must use the formula A = (b_1 + b_2)h/2, so you do (175 + 185)100/2 which is 360*50 = 18000cm².
A = 18000 cm²
Problem 2:
Just use the shown formula, so it would be 40/100 = x/Area, 40*18000/100 = 40*180 = 7200cm²
Available lot coverage = 7200cm²
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.
What is a trapezoid?A trapezoid is a four-sided shape that has one pair of sides parallel.
We have,
Area of a trapezoid:
= 1/2 ( a + b ) h
a and b are the two parallel sides.
h = height of the trapezium.
We have,
a = 175
b = 185
h = 100
Area of a trapezoid:
= 1/2 x ( 175 + 185 ) x 100
= 1/2 x 360 x 100
= 18000
We will calculate 40% lot coverage of the 18000 area.
40% = 40 / 100
So,
= 40/100 x 18000
= 7200
Thus,
The area of the trapezoid is 18000 square units.
The area available for lot coverage is 7200 square units.

given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}

O Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease
Answer:
Some measures I believe you are talking about are mean, median, mode, and range.
Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.
Example:
1, 2, 4, 6, 10
(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6
1, 2, 4, 6
(1 + 2 + 4 + 6)/4 = mean = 3.25
Because of this, mean does change when adding and removing outliers, and is therefor not the answer.
Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.
Example:
1, 2, 4, 6, 10 Median = 4
1, 2, 4, 6 Median = 3
So median is not the answer, because it is affected by adding and removing outliers.
Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.
Example:
1, 1, 1, 2, 3, 4, 4, 86 Mode = 1
1, 1, 1, 2, 3, 4, 4 Mode = 1
This means the mode is not affected by adding and removing outliers.
Mode is a possible answer, but let's take a look at range before coming to a conclusion.
Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.
Example:
1, 2, 4, 6, 10
10 - 1 = highest value - lowest value = range = 9
1, 2, 4, 6
6 - 1 = highest value - lowest value = range = 5
The range is certainly affected by outliers, so it is not the answer.
Out of mean, median, mode, and range, the answer to this question is mode.
If an outlier is removed, mode will not change.
Hope this helps!

What is the median number of students in these classes?
Answer:
22
Step-by-step explanation:
Put them in order from least to greatest
18,19,22,22,24
Then cross one out from each side
19,22,22
Then cross one out from each side again

a whole number by a unit fraction is the same as multiplying a whole number by the of the unit fraction.
Answer:
A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.
Step-by-step explanation:
Given
[tex]8 \div \frac{1}{5} = 40[/tex]
[tex]8 * 5 = 40[/tex]
Required
Explain why both expressions are correct
No dropdown to select from. So, I will provide a general solution.
When a number is divided by a fraction.
Take for instance:
[tex]8 \div \frac{1}{5}[/tex]
The above can be expressed as the product of the number and the inverse of the fraction.
The inverse of 1/5 is 5.
So, we have:
[tex]8 \div \frac{1}{5} = 8 * 5[/tex]
The result of the above expression is:
[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]

Suppose 288 electricians took a certification test that is worth 140 points. The five-number summary for the scores is shown here.
min. value = 68
Q1 = 110
median = 125
Q3 = 130
max. value = 138
About how many electricians had a score of 110 or less? A: 72 B: 130 C: 144 D: 216
Answer:
72
Step-by-step explanation:
For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:
0.25 * 288 = 72.
