Satara was having fun playing poker. She needed the next two cards dealt to be hearts so she could make a flush (five cards of t

evablogger [386]

Answer:

Step-by-step explanation:

Given the following :

Total Number of cards left in deck = 10

Number of hearts left in deck = 3

Probability = (required outcome / Total possible outcomes)

Required outcome = hearts card in deck

Two cards are to be dealt to Satara without replacement :

Probability of 1st card being hearts :

P(1st card being hearts) = required outcome / Total possible outcomes

P(1st card being hearts) = 3 / 10

Probability of 2nd card being hearts :

Since it is without replacement :

Required outcome = (3 - 1). = 2

Total possible outcomes = (10 - 1) = 9

P(2nd card being hearts) = 2 /9

Probability of the two cards being hearts :

(3 / 10 × 2/9) = 6 /90 = 0.0666

0.06666 × 100% = 6.66%

= 7% (nearest whole number)

Which statement is true about the purpose of trend lines in scatterplots? A trend line must pass through the largest data point.

Eddi Din [679]

Answer:

a trend line can be used to make predictions in real-world situations (the third option)

Explanation:

the first & second options are wrong because it is not a requirement for a trend line to pass through any given data point.

the fourth option is wrong because a trend line shows the general upward/downward trend of the data, and may not necessarily touch all of the data points.

the third option is correct because a trend line helps to roughly estimate the trend (hence the name) of the graph, which allows us to make predictions in real-world situations.

i hope this helps! :D
