where RS = 6y + 2, ST = 2y + 7, and RT = 13y - 21.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete but a possibility is that the given parameters are points on a straight line.
I'll answer base on that assumption.
[tex]RS = 6y + 2[/tex]
[tex]ST =2y + 7[/tex]
[tex]RT =13y -21[/tex]
To solve for y, we have that:
[tex]RT = RS + ST[/tex]
This gives:
[tex]13y - 21 = 6y + 2 + 2y + 7[/tex]
Collect Like Terms
[tex]13y - 6y - 2y = 21 +2+7[/tex]
[tex]5y = 30[/tex]
Divide both sides by 5
[tex]y = 6[/tex]
To get the measure of each line. Substitute 6 for y in
[tex]RS = 6y + 2[/tex]
[tex]ST =2y + 7[/tex]
[tex]RT =13y -21[/tex]
[tex]RS = 6 * 6 + 2 = 36 + 2 = 38[/tex]
[tex]ST = 2*6 + 7 = 12 +7 = 19[/tex]
[tex]RT = 13*6 - 21 = 78 - 21 = 57[/tex]

What is standard deviation?A measure of a set of values' variance or dispersion is called the standard deviation. Because it aids in comprehending measurements when the data is scattered, standard deviation is significant. The greater the distribution of the data, the higher its standard deviation will be..l

Suppose that fund-raisers at a university call recent graduates to request donations for campus outreach programs. They report the following information for last year's graduates.
Size of donation $0 $10 $25 $50
Proportion of call 0.40 0.30 0.25 0.05
Three attempts were made to contact each graduate. A donation of $0 was recorded both for those who were contacted but who declined to make a donation and for those who were not reached in three attempts. Consider the variable
x = amount
of donation for the population of last year's graduates of this university.
(a) Write a few sentences describing what you think you might see if the value of x was observed for each of 1000 graduates.
You would expect roughly of the graduates to donate nothing, roughly to donate $10, roughly to donate $25, and roughly to donate $50. The frequencies would be close to, but not exactly, these values. The four frequencies would add to .
(b) What is the most common value of x in this population?

(c) What is P(x ≥ 25)?
(d) What is P(x > 0)?

In point a:
It's also expected that approximately [tex]1000 \times 0.40 =400[/tex] of both, the students contribute zero, approximately [tex]1000 \times 0.30 =300[/tex] to donors $10, approximately [tex]1000 \times 0.25 = 250[/tex] donors $25, and then about [tex]1000 \times 0.05 = 500[/tex] dollars $50 donors.

The only decimal that contains a digit that represents ten times the value of the digit to its' right is; 33.458
How to Interpret Decimals?From the question, we want to find the digit that represents ten times the value of the digit to its' right.
Now, when it comes to decimals, there is the whole number part which is the left side of the decimal while there is a fraction part which is the right side of the decimal.
Now, the decimal values given are;
36.295
33.458
37.889
Let us analyze each of them;
1) 36.295 = 30 + 6 + 2/10 + 9/100 + 5/1000
We can see that there is no number that is ten times the number to it's immediate right.
2) 33.458 = 30 + 3 + 4/10 + 5/100 + 8/1000
We can see that 30 is ten times the number to it's immediate right which is 3.
3) 37.889 = 30 + 7 + 8/10 + 8/100 + 9/1000
We can see that there is no number that is ten times the number to it's immediate right.

Weight of oranges bought = $7.14 ÷ $1.19
= 6 pounds
Weight of pears bought = $5.16 ÷ $1.29
= 4 pounds
Total weight of fruits bought = 6 + 4
= 10 pounds

If the function h(t) = tan(5t +4 ) using chain rule we found values h'(1)= 6.02 and h"(1) = -27.24
What is chain rule for differentiation?Chain rule for differentiation states that the differentiation of the composition of two functions f, g
(fоg)' = f'(g(x))* g'(x) , where ' represents first derivative with respect to independent variable x .
For three functions : x, y, t
(x(y(z(t))))' = x'(y(z(t)))*(y'(z(t)))*z'(t)
Given h(x) = tan(5t+4)
Let f(t) = tan t and g(t) = 5t+4
f'(t) = sec² t and g'(t) = 5
Then h(t) = fоg(t)
Using chain rule of differentiation:
h'(t) = (fоg(t))' = f'(g(t))* g'(t) = sec²(5t+4) *(5) = 5 sec²(5t+4)
let x(t) = 5t², y(t) = sec(t), z(t) = 5t+4
x'(t) = 10t , y'(t) = sect tan t , z'(t) =5
(x(y(z(t))))' = x'(y(z(t)))*(y'(z(t)))*z'(t)
h"(t) =(x(y(z(t))))'= 10 sec(5x+4) * sec(5t+4)tan(5t+4)*5
h"(t) = 50sec²(5t+4)tan(5t+4)
The value of h'(t) at t =1
h'(1 ) = 5 sec²(5(1)+4)= 5 sec²(9) =6.02
h"(1) = 50sec²(5(1)+4)tan(5(1)+4) = 50sec²(9)tan(9) = -27.24
Therefore, the values h'(1 ) = 6.02 and h"(1) = -27.24

Joshua drove his car a distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answer:
6 liters of gasoline
Step-by-step explanation:
Since, 1 km = 0.6214 miles
Therefore, 100 km = 0.6214 × 100 = 62.14 miles
∵ For 431.8 miles of driving Joshua required amount of gasoline = 10.4 gallons
∴ For 1 mile of driving gasoline required = [tex]\frac{10.4}{431.8}[/tex] gallons
∴ Gasoline required to drive 62.14 miles = [tex]\frac{10.4}{431.8}\times 62.14[/tex] gallons
= 1.4967
≈ 1.5 gallons
∵ 1 gallon of gasoline = 3.8 liters
∴ 1.5 gallons of gasoline = 3.8×1.5
= 5.7
≈ 6 liters
The number of liters of fuel should be 6 liters.
Calculation of number of liters:Since distance of 431.8 miles, and it required 10.4 gallons of gasoline (petrol).
So,
Since, 1 km = 0.6214 miles
Now
100 km = 0.6214 × 100 = 62.14 miles
The number of liters should be
[tex]= 10.4 \div 431.8 \times 62.14 \times 3.8[/tex]
= 6 liters

What is the domain of the function y=x-1
Answer:
All rational numbers or all numbers
Step-by-step explanation:
The function is a linear positive slope equation, which looks like the screenie below. Lines always travel forever, and since it is a linear line with a slope, it will be forever going in both directions.
Domain is the x-values that a function has, while range is the y-values.
Since the domain and range are infinite, it is all real numbers.
