Answer:

1.6

Step-by-step explanation:

So, first, write down the number of jokers in each deck of cards.

That would be: 0, 1, 2, 2, 3

Then, add up all those numbers.

0+1+2+2+3=8

Now, divide that sum by the number of decks or cards shown in the data set, which would be 5.

8/5=1.6

So, the mean of the data in the dot plot shown is 1.6.

Convert 49° Celsius to degrees Fahrenheit using the following formula: F = {C+32 O A. 506.5°F OB. 196.2°F C. 94.6°F OD. 2237°F O E. 120.2°F​

Answers

Answer:

Step-by-step explanation:

F = 9/5C + 32

Putting value

9/5(49) + 32

88.2 + 32

= 120.2°F

Option E is the correct answer

The Celsius temperature 49 in Fahrenheit is 120 F.

To convert Celsius to Fahrenheit, you can use the formula:

F = (C × 9/5) + 32

Let's calculate the conversion using the given Celsius value:

C = Celsius temperature

F = (C × 9/5) + 32

F= (49 x 9/5)+ 32

F= 88.2 + 32

F = 120.2 F

Thus, Celsius temperature 49 in Fahrenheit is 120 F.

Step-by-step explanation:

The distance formula is useful for finding the length of a line segment.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

Filling in the point coordinates L(-5, -3) and M(0, 4), we find the length of LM to be ...

Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes

Probability refers to a possibility that deals with the occurrence of random events also can be state as all the events occurring need to be 1.
