sammy [17]

Answer:

x = 9

Over [174]

Answer:

The expected number of wins for the​ player is 2.31

Step-by-step explanation:

No. of face cards = 12

total cards = 52

Probability of getting face card = \frac{\text{No. of face cards}}{\text{Total No. of cards}}

Probability of getting face card = \frac{12}{52}

The player plays 10​ times

Formula : E=np

n = no. of trials = 10

p = probability of success= \frac{12}{52}

E=expected number of wins

E=10(\frac{12}{52})

E=2.307

So,  the expected number of wins for the​ player is 2.31

An ant can travel at a constant speed of 980 inches every 5 minutes. At this rate, how far can the ant travel in 7 minutes?
Zarrin [17]

Answer:

1372\: \mathrm{inches}

Step-by-step explanation:

Since the ant travels at a constant speed, we can set up the following proportion:

\frac{980}{5}=\frac{x}{7}, where x is the distance the ant can travel in 7 minutes.

Solving for x, we get:

x=\frac{7\cdot980}{5}=\fbox{$1372\:\mathrm{inches}$}.
