Answer:

Total amount spread on electricity in three months is $784.98.

Step-by-step explanation:

Tan's electricity bill for the month of August was $267.00.

It is given that the September bill showed a 2% increase from his August bill.

Increase in electricity bill is 2% of $267.00.

\frac{2}{100}\times 267=5.34

The electricity bill for the month of September is

267.00+5.34=272.34

It is given that in October, his bill decreased 8% from the amount he was billed in August.

decrease in electricity bill is 8% of $267.00.

\frac{8}{100}\times 267=21.36

The electricity bill for the month of October is

267.00-21.36=245.64

Total amount spread on electricity is

Total=267.00+272.34+245.64=784.98

Therefore total amount spread on electricity in three months is $784.98.

Given that it was less than 80º on a given day, what is the probability that it also rained that day? 0.3 0.35 0.65 0.7
eimsori [14]

The probability that it also rained that day is to be considered as the 0.30 and the same is to be considered.

<h3>What is probability?</h3>

The extent to which an event is likely to occur, measured by the ratio of the favorable cases to the whole number of cases possible.

The probability that the temperature is lower than 80°F and it rained can be measured by determining the number at the intersection of a temperature that less than 80°F and rain.

So, This number is 0.30.

Hence, we can say that it was less than 80°F on a given day, the probability that it also rained that day is 0.30.

To learn more about the probability from the given link:

brainly.com/question/18638636

The above question is incomplete.

The conditional relative frequency table was generated using data that compared the outside temperature each day to whether it rained that day. A 4-column table with 3 rows titled weather. The first column has no label with entries 80 degrees F, less than 80 degrees F, total. The second column is labeled rain with entries 0.35, 0.3, nearly equal to 0.33. The third column is labeled no rain with entries 0.65, 0.7, nearly equal to 0.67. The fourth column is labeled total with entries 1.0, 1.0, 1.0. Given that it was less than 80 degrees F on a given day, what is the probability that it also rained that day?

Multiply. Express your answer in simplest form. 5/8, 24
musickatia [10]
A number without denominator such is equal to number with denominator 1.
So, 24 is equal to 24/1


5/8 x 24

= 5/8 x 24/1

= (5x24) / (8x1)

= 120/8


= 15
