Answer:

Step-by-step explanation:

The equation of the linear regression line represents the relationship between

From the above question, let's represent:

Number of candles sold for charity = x

The amount earned for charity = y .

Our equation is given as:

ŷ = 10x +41

Hence, x = 47

y = 10 × 47 + 41

y = 470 + 41

y = 511

The amount of money the charity should expect is 511

Answer:

x=11.2

Step-by-step explanation:

Set up a proportion:

x+11/36 = 37/60

Cross multiply:

1332=60(x+11)

Distribute:

1332=60x+660

Subtract 660 from 1332

672=60x

Divide:

x=11.2

I'm not sure if this is the correct answer but I hope this helps! :)

Alborosie

Answer: $8t+581$

Step-by-step explanation:

<h3> The complete exercise is: "Omar works as a tutor for $15 an hour and as a waiter for $7 an hour. This month, he worked a combined total of 83 hours at his two jobs. Let "t" be the number of hours Omar worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month."</h3><h3 />

Let be "t" the number of hours Omar worked as a tutor this month and "w" the number of hours Omar worked as a waiter this month.

Based on the data given in the exercise, you know that Omar worked a combined total of 83 hours this month.

Then, you can represent the number of hours he worked as a waiter this month with this equation:

$w=83-t$

Since he earns $15 per hour working has a tutor and $7 per hour working as a waiter, you can write the following expresion to represent the total money earned:

$15t+7w$

Since $w=83-t$ , you can substitute it into the expression and then simplify it in order to find the final expression that represents the total amount of money Omar earned this month.

This is:

$15t+7(83-t)=15t+581-7t=8t+581$

*MAJOR POINT BOOST*<br> describe the fibonacci sequence in a detailed explanation

Kryger [21]

The Fibonacci Sequence is a stream of numbers that typically begins with a "0" or "1". From there, any number placed after would be added to the previous number.
For instance, if I started with a "1", and the next number was a "2", the number after would be a "3". From this "3", it would be a "5", the next number would then be a "8".
It would look like this:
1, 2, 3, 5, 8
