20. The temperature of a pot of water is 62*F. The temperature increasesby 20*F per minute when being heated. Write an equation to represent

the linear relationship. *

Answers

Given :

The temperature of a pot of water is 62 F .

The temperature increases by 20 F per minute when being heated .

To Find :

Write an equation to represent the linear relationship.

Solution :

Here , the temperature is increasing directly with the time .

Therefore , it is a linear equation .

Let temperature varies with as :

T = at+b .... equation 1 .

( Here , a and b are constants )

Now , at t= 0 min .

$T = 62 =a* 0 + b$

$b=62$

Now , after 1 min temperature will be , T = 62 +20 =82 F

$T = 82 = a* 1+62\na=20$

Putting value of a ans b in equation 1 , we get :

$T=20t+62\ F$

Hence , this is the required relation .

What is the slope of a line that passes through points (-1, 4) and (4, 9)?

Answers

The slope is (difference in 'y') divided by (difference in 'x') .

Difference in 'y' = (9 - 4) = 5

Difference in 'x' = (4 - [-1]) = 5

Slope = 5/5 = 1 .

(I don't think we need the pictures at all.)

Ok here is the graph. And all of the Different slopes.
The slope would be Positive Slope!

The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62.The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Anna is on holiday in Portugal.
She posts 15 postcards to the UK on Monday.
How many of her postcards can she expect to be delivered within a week?
(2 marks)

Answers

Answer:

You can expect at least 9 of her postcards to arrive within a week

To find that, we multiply the number of postcards by the probability

15 x 0.62 = 9.3

Hope this helps
