What is the sine rule for a triangle?The sine rule for triangle ABC is a/sinA = b/sinB = c/sinC.
Given, Lisa and Molly are standing on a bridge and see a tree sticking out of the water.
m∠M = 103°, m∠L = 54°, and the side opposite to ∠L is l which is 22 feet and m is the side opposite to ∠M.
∴ 22/sin54° = m/sin103°.
22/0.8 = m/0.97.
m = 26.67 feet.

Which set represents y as a function of x
Answer:
the answer would be c.
Step-by-step explanation:
in order to be a function the x axis cannot repeat itself. after process of elimination you are left with c which is the only option in which x does not repeat.
Suppose the distribution of a set of scores has a mean of 47 and a standard deviation of 14. If 4 is added to each score, what will be the mean, standard deviation, and variance of the distribution of new scores?
Answers:
New Mean = 51New Standard Deviation = 14New Variance = 196================================================
Explanation:
Consider the set {x1,x2,x3,...,xn}. The numbers 1,2,3,...,n represent the index of each x value. So we have n numbers we want to find the average.
The sum of those values is
S = x1+x2+x3+...+xn
When dividing that over n, we get the average A
A = S/n
A = (x1+x2+x3+...+xn)/n
-----------------
Now consider adding 4 to each x value
We have this new set
{x1+4, x2+4,x3+4,...,xn+4}
The new sum T is
T = (x1+4)+(x2+4)+(x3+4)+...+(xn+4)
T = (x1+x2+x3+...+xn) + (4+4+4...+4)
T = S + 4n
Divide both sides by n
T/n = (S+4n)/n
T/n = (S/n) + (4n/n)
T/n = (S/n) + 4
T/n = 47+4
T/n = 51
The new average T/n is 4 larger compared to the old average S/n. So we just add 4 to the old average 47 to get 51 as the new average.
-----------------
If we shift every value the same amount, then the standard deviation and variance will not change. This is because both of those items measure how spread out a distribution is. Shifting each item the same amount, keeps the same spread and shape of the distribution. If only affected some of the items, then the standard deviation and variance would change.
Note that,
variance = (standard deviation)^2
variance = (14)^2
variance = 196
What’s the rate of change

Answer:
Jane's situation is the one which represents a porportional relationship.
Step-by-step explanation:
To verify the proportionality betwen a ratio you have to divide all the ratios and all them have to get the same constant factor.
So, if you divide the matt's ratios you aren't gonna find the same constant factor
12/1=12
20/2=10
31/2=15,5
But if you try with Jane's ones:
12/1=12
24/2=12
36/3=12
This 12 is the known constant factor, which show us that these ratios are proportional.

3(t-8)=9 as a sentence
Answer:
The difference of t-8, multiplied by 3
Correct me if i'm wrong
The expression in the word form can be written as the difference of t-8, multiplied by 3.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 3(t-8)=9 the word form will be written as below:-
3(t-8)=9 = The difference of t-8, multiplied by 3.
3(t-8)=9
3t - 24 = 9
3t = 33
t =11
Therefore, the expression in the word form can be written as the difference of t-8, multiplied by 3.

What percentage of total hours were spent skiing?
Soccer 5
Jogging 20
walking 10
skiing 5
football 10
Answer:
10%
Step-by-step explanation:
5/50=x/100
5×100=500
500/50=10
x=10
10%
Percentage of total hours were spent skiing is 10%
What is the percentage?Percentage is defined as a relative value indicating 100th parts of any quantity. It is denoted by symbol of %.
Given that,
Soccer = 5 hours
Jogging =20 hours
Walking =10 hours
Skiing = 5 hours
Football = 10 hours
Total hours were spent all activity = 5+20+10+5+10=50
Let, percentage of total hours were spent skiing = x
5/50=x/100
5×100=500
500/50=10
x=10
Hence Percentage of total hours were spent skiing is 10%
