Answer:

kei = kelvin\_kei(x) evaluates an approximation to the Kelvin function kei x. The function is based on several Chebyshev expansions. For large x, kei x is so small that it cannot be computed without underflow and the function fails.

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.

Percentage of total hours were spent skiing is 10%

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%

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.

The correct answer is 26.5ft

The distance between the stick and Lisa is C) 45.6 ft.

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.

================================================

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

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.

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.
