Answer:6
Step-by-step explanation:
Heron's Formula is: area = sqrt(s(s-a)(s-b)(s-c)) and s is the semiperimeter
Putting the side lengths in would be:
s = (a + b + c)/2
area = sqrt(6(6-5)(6-4)(6-3)) = sqrt(6*1*2*3) = 3*sqrt(2)
So the answer is 3*sqrt(2) which is equal to 6
Answer:
6 units²
Step-by-step explanation:
You want the area of the 3-4-5 right triangle.
AreaThe area formula for a triangle is ...
A = 1/2bh
where b represents the "base" and h represents the "height". The height is always measured to the vertex opposite the base, in direction perpendicular to the base.
Right triangleThe perpendicular legs of a right triangle have the necessary relationship for either one to be considered the "base", and the other to be the "height."
Here, that means we can call the side of length 3 units the "base" and the side of length 4 units the "height", or vice versa.
This means the area is ...
A = 1/2(3 units)(4 units) = 6 units²
__
Additional comment
Heron's formula for the area of a triangle based on all three side lengths can be used for this, but is more work than necessary.

Answer: The answer to 2, 6, 12, 16 is 9 and the answer to 5, 6, 12, 13 is 9
Step-by-step explanation: The mean of a set of numbers is another term for average. You add all of the numbers up like for example in the second set of numbers, 16+12+6+2 is equal to 36 and you then divide that sum by the amount of numbers you added which in this case is 4 so you get 36/4 which is equal to 9.
Mean of 2, 6, 12, 16 = (2 + 6 + 12 + 16) ÷ 4 = 36 ÷ 4 = 9
Mean of 5, 6, 12, 13 = (5 + 6 + 12 + 13) ÷ 4 = 36 ÷ 4 = 9

Data Set : {8, 2, 5, 0, 1, 9, 2, 5, 2}
Arrange in ascending order : {0, 1, 2, 2, 2, 5, 5, 8, 9}
Range = Last Term - First Term = 9 - 0 = 9 is the range
Mean = sum of terms/number of terms = 34/9 = 3.777... = 3.78 is mean
Mode = the most appearing integer in the set = 2 is the mode
Median = The integer at the middle of the set = 2 is the median
======================
Range = 9Mean = 3.78Mode = 2Median = 2Mean: Add up all the numbers and divide by the amount of numbers. 8+2+0+1+9+2+5+2= 29 then divide by 9 = 3.22 therefore the mean is 3.22.
Mode: Number that appears the most frequent. There can be multiple. In this case the mode is 2.
Median: The middle number. First order from lowest to highest: 0,1,2,2,2,5,8,9. In this case the median is 2 and 2. So we simply add 2+2 which equals 4 and divide it by 2. Therefore the median is 2. Hope this helped!!

Step-by-step explanation:
y=total amount of money
b=cost of admission
m=cost per ride
r= amount of rides
How to solve:
Step 1: Set up the equation in [tex]y=mx+b[/tex] format.
[tex]23=22+0.50r[/tex]
Step 2: Subtract 22 from both sides of the equation.

The mean of the scores is approximately 6.2. The correct answer is (C).
What is arithmetic mean?The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
To calculate the mean of the scores based on the given frequency table, we need to multiply each score by its corresponding frequency, sum up the results, and then divide by the total frequency.
Let's perform the calculations:
(1 x 1) + (2 x 1) + (3 x 3) + (4 x 1) + (5 x 4) + (6 x 5) + (7 x 6) + (8 x 5) + (9 x 3) + (10 x 1) = 167
1 + 2 + 9 + 4 + 20 + 30 + 42 + 40 + 27 + 10 = 185
The total frequency is 1 + 1 + 3 + 1 + 4 + 5 + 6 + 5 + 3 + 1 = 30
Now, we divide the sum (185) by the total frequency (30) to find the mean:
185 / 30 = 6.1667
Rounding this value to the nearest tenth, the mean of the scores is approximately 6.2.
Therefore, the answer is C) 6.2.
