Look at the triangle below.
Which equation is equivalent to the law of cosines?
A
a2=c2−2cx+h2
B
a2=c2−2cx+x2+h2
C
a2=c−x2+h2
D
a2=c2−x2+h2
Answer:
I believe the answer is B. a^2 = c^2 - 2cx + x^2 + h^2
Step-by-step explanation:
The law of cosines states: c^2 = a^2 + b^2 - 2bc * cos(C). If we plug in the values from the diagram, we'll have (c-x)^2 = a^2 + h^2 -2ah * cos(90)
cos(90) = 0, so now we have just (c-x)^2 = a^2 + h^2
Let's expand this to c^2 -2cx + x^2 = a^2 + h^2
Isolate a^2 and we now have a^2 = c^2 -2cx + x^2 + h^2

1.) A six-sided number cube is rolled, and the spinner
below is spun. Determine the probability of rolling a 3 and
spinning blue. (B=blue, R=red) Express your answer as a
fraction, a decimal, and a %.
Answer:
Step-by-step explanation:
The question is not totally clear. I will assume that the spinner has 2 colors, red and blue.
Your chances of rolling a 3 are 1 in 6 = 1/6
Your chance of getting blue is 1/2
Your chances are 1/2 * 1/6 = 1/12
As a decimal that is 0.0833333
As a % it is 8.3333 %

write and solve an equation to find the value of X. please explain in details and show your work!
Answer:
Ok. so let's teach you how to find the angles of a triangle. When you add all three sides, they must equal 180 degrees. Because of this, let's do some math. What is 96+35. Ima pretend you said 131 and so you would be right. Now let's subtract that from 180 degrees. 180-131 is 49 and so x is 49 degrees. Hope this helps!!
Can a set of data having two modes have two points of central tendency
Answer:
The Measure of Central Tendency are
1. Mean
2. Median and Quartiles
3. Mode
4. Geometric Mean
5. Harmonic Mean
→When all the five Measure of Dispersion are Same, it means the two data sets have Identical Variate.
→Now consider the two data sets,
A=3,4,4,5
B=1,4,4,7
Both the Data set have , same mean, median, and Mode,which is equal to 4.
→When you will consider, First three as Measure of central tendency ,then it becomes incorrect statement ,that Data Set are same.
Step-by-step explanation:
A measure of central tendency is a descriptive statistic
The correct response to the question is as follows;
Yes; A data having two modes can have two points of central tendency
The reason a dataset having two modes can have two points of central tendency is as follows:
A dataset having two modes is said to be bimodal
A dataset having three modes is said to be trimodal
A dataset having more than three modes is said to be multimodal
A measure of central tendency is a type of summary statistics that is a
single value representing the center point, or average of a set of data
thereby providing a description of the data by telling the middle value, the
average or the most common value which is the mode
As can be seen from the given example, by having two modes, a bimodal
data set describes a data that has two points of central tendency, thereby
giving a description of the data type, which for example may a collection
of the height of individuals, male and female, that have two most common
height values for each gender
Therefore, the correct response is yes, a dataset having two modes can
have two points of central tendency because the mode is a measure of
central tendency which is a descriptive statistics

5x + 4m = 43my + 6 solve for m
9514 1404 393
Answer:
m = (5x -6)/(43y -4)
Step-by-step explanation:
Subtract 4m+6 to separate m-terms from other terms.
5x +4m -(4m +6) = 43my +6 -(4m +6)
5x -6 = 43my -4m
5x -6 = m(43y -4) . . . . factor out m
(5x -6)/(43y -4) = m . . . . divide by the coefficient of m
What is the least three-digit whole number that has exactly five positive factors?
There is no three-digit whole number that has exactly five positive factors.
The prime factorization of a number with five factors will be of the form p⁴ or p²q, where p and q are distinct prime numbers.
p⁴:
The smallest prime number greater than or equal to 10 is 11.
So, let's consider 11⁴:
11⁴ = 14641 (which is a five-digit number)
p²q:
To minimize the number, we need the smallest prime numbers possible. The two smallest prime numbers greater than 10 are 11 and 13.
Let's consider the product of these two primes:
11² × 13 = 1573 (a four-digit number)

Given that mercury has a freezing point of -38°F and water has a freezing point of 32°F.
The difference between the freezing point of water and mercury is calculated below
Difference = freezing point of water - freezing point of mercury
Difference = 32 - ( -38)
Difference = 70°F

solve 4(x-3) -2(x+1) =2
Answer:
8
Step-by-step explanation:
4(x-3) -2(x+1) =2
=> 4x - 12 - 2x - 2 = 2 [opening brackets]
=> 4x - 2x - 12 - 2 = 2
=> 2x - 14 = 2
=> 2x = 14 + 2
=> 2x = 16
=> x = 16/2
=> x = 8
4 ( x - 3 ) - 2 ( x + 1 ) = 2
2 ( x - 3 ) - ( x + 1 ) = 1
2x - 6 - x -1 = 1
2x - x = 1 + 6 + 1
x = 1 + 6 + 1
x = 7 + 1
x = 8
